New in mrViewer 5.6.2 (Sep 8, 2020)

  • Fixed ocio* utilities on Windows which used OpenImageIO.

New in mrViewer 5.6.1 (Aug 27, 2020)

  • Removed all aces_* from distribution as they were taking too muchspace (the latest aces_1.3 was 2GB). Left only nuke-default.To download the other configs, please go to opencolorio.org forinstructions. Now the installers are around 84Mb, instead of 256Mb.
  • Switched compilers and Linux version to Ubuntu 16.04. This wasneeded to compile the latest OpenColorIO and OpenImageIO. Thismeans we are no longer compatible with really old versions ofLinux distros.
  • Compiled oiiotool on Windows with latest OpenImageIO and OpenColorIOand OpenEXR 2.5.2.
  • Bug fixed removal of old mrViewer from PATH when installing fromchocolatey.- Added the option to keep all nuspecs for downloading old chocolateyimages from archive. Now the install will try to download firstfrom the normal location and if it fails, it will try to downloadfrom the archive location.

  • Added the option to override the hotkey when a matching hotkey isfound.

New in mrViewer 5.6.0 (Aug 19, 2020)

  • Changed icons in Action Tools to a simplified version of them which hopefully makes them more clear.
  • Made the hotkeys 'k' (play forwards), and j (play backwards). Hitting them multiple times increments the speed of playback in that direction (or reverses the playback if less than the default speed). The previous 'k' (Clear Caches) is changed to SHIFT+'k' and 'j' (Swap FG/BG image) is changed to SHIFT+j.
  • Made area selection be temporary when SHIFT+Drag. But be persistent when selected from the action tool box.
  • Changed default color of pencil drawing to be bright green, instead of dull green.
  • Changed all text in Action Tools to be white/whitish instead of black.

  • Added a check for hotkeys already in use. mrViewer will now not allow you to set the same hotkey to different functions.
  • Bug fixed a bug in hotkeys which would not allow clearing the hotkey.
  • Added Draw Temporary and Erase Temporary modes. They are there so a hotkey can be assigned to them, with no hotkeys assigned to them. The idea is that if, for example, 'd' is assigned to draw, hitting 'd' will switch from scrub mode to draw mode and when released scrub mode will be selected again. This is similar to the SHIFT key of temporary selection mode.
  • Split the hotkeys from the main preferences file. Now hotkeys are stored in a mrViewer.keys.prefs file in the $HOME/.filmaura directory.
  • Made Text tool requester remember the font and size selected between each call.
  • Bug fixed Text tool transparency on ghosting.

  • Bug fixed Preferences->Cache->Image Cache Size setting. Now floatingpoint values are accepted. Also added arrows to allow setting the cache value in increments of 0.5 Gb.
  • BRAW and R3D formats now read Preferences->Cache->Image Cache Size and will try to limit the clips reading of frames to that memory limit and will recycle frames if they won't fit. However, it will also perform like a soft limit that will be overrun if you have several clips that you want to play. The biggest benefit comes from playing a single clip at a big resolution (1/2 or 1/4 for example) and recycling the frames.
  • BRAW now supports timecode and it matches BlackmagicRAWPlayer.
  • Fixed timecode when it was drop frame and it was less than 30 or not a multiple of 30. Now those cases behave as non-drop frame.
  • Fixed timecode when switching FPS value.
  • Bug fixed looping of sequences that start at another frame than 1 when using the FFMPEG library for one of its known image formats.
  • Previously, the looping would work only once.

  • Removed errors popping up when file requester is used.
  • They will get printed to stderr and to the log window, but the log window will not get raised.
  • Added support for Blackmagic's RAW video format and audio on Linux and Windows 64 bits. Windows 32 bits does not support it as there's a lack of a library for reading it on that platform.
  • Also note that BRAW's Metadata is only partially supported as array data is not read.

New in mrViewer 5.3.9 (Feb 16, 2020)

  • Bug fixed loading of pngs and similar with just lumma and with or without alpha channel.

New in mrViewer 5.3.7 (Jan 20, 2020)

  • Made the default transform for byte/short videos be sRGB or Output - sRGB instead of scene_linear, depending on what ocio config you are using (nuke-default or aces). Note that you can still override this if you specify in the OCIO preferences section for each image depth what color space to use.
  • Added playback of http:// and https:// videos with the help of youtube-dl. Note that .srt/sub/vtt subtitles are not yet automatically downloaded. This allows playing most youtube videos that do not have a playlist either thru the command-line or thru drag and drop (at least with firefox).
  • Added saving and loading of fade information in reel file.
  • Fixed text color scheme in gtk+ and Black color scheme for most widgets. Some widgets still refuse to coperate ( the color info window mainly ).

New in mrViewer 5.3.4 (Dec 21, 2019)

  • Made all R3D color changes be interactive.
  • Added pull down menus to color space and gamma curve in the R3D section of the image information window.
  • Made R3D color space selection modify the image's input color space so as to make it easier to see the images in the right color space. This works similar to Nuke, but better as it distinguishes between nuke-default's and aces' colorspaces.
  • Added support for legacy color pipeline (color version 2) in R3D movies. Most elements now work.
  • Added brightness, contrast, saturation, gain, etc. to R3D's media info.
  • Added 1:1, 1:2, 1:4 and 1:8 pulldown menu to media info to control the size of each R3D clip, instead of relying on the global cache pulldown.

  • Made thumbnails respect flip on x and flip on y.

New in mrViewer 5.3.3 (Dec 15, 2019)

  • Added .r3d (RED core) format to list of available movie formats. The decompression is done on the CPU and it takes into account the Cache Scale setting in the Preferences. The current color pipeline is IPP2 only. The legacy pipeline is not currently supported. To turn a legacy pipeline into IPP2, Use the two buttons labeled Load RMD and Reset to Camera. Then select Input - RED - Log3G10 - WideGamutRGB.
  • Made EDL switching more thread safe by temporarily stopping the playback.
  • Made Auto Fit Image be faster to not allow flickering frames not in their correct size and position.
  • Made OCIO's config file be selectable without exiting mrViewer. The switch happens automatically.

  • Bug fixed padding in sequences when a frame range is provided.
  • Made otio<->reel converter more solid and added features in mrViewer to support the conversion more seamlessly.
  • Added a first command-line video tutorial for OpenTimelineIO usage in:
  • https://youtu.be/yXaYj406xiM

New in mrViewer 5.2.7 (Oct 8, 2019)

  • Bug fixed .reel saver to save the fps with decimals. Previously, only integers were saved.
  • Made Preferences->Loading->Missing Frame be an automatic setting with no need to save it and reload mrViewer.
  • Fixed FPS extraction from reels without FPS (old reels). Now they default to 30.0 fps.
  • Bug fixed I/O buttons and end frame/start frame in timeline to set the loops regardless of how the view of the timeline is (timeline shown as overlay or timeline cut at the ends).
  • Fixed hotkeys for set In and set Out in timeline.
  • Bug fixed IN / OUT points setting which were being set up multiple times and so resetting themselves.
  • Merged repositories to both github and sourceforge. They are now in sync and only one remains on each site.
  • Bug fixed native file chooser on Linux to save images or image sequences. Note that the native file chooser on Linux is huge so it may not be the one you want by default.

New in mrViewer 5.2.6 (Sep 27, 2019)

  • Improvments to the otio<->reel converter. Now the clip name is attempted to be kept in both directions.
  • The otio<->reel converter now defaults to relative paths. This can be overriden by using -a relative_paths = False or
  • A relative_paths = False depending on whether you are reading or writing a .reel file.
  • Bug fixed a problem with XML ACES files when loading checkered images.
  • Bug fixed a huge memory leak in reel images which in time would slow everything down.
  • Bug fixed scratched pictures missing on Linux.
  • Bug fixed saving of images/movies as the native file requester would crash on both Windows and Linux.

New in mrViewer 5.2.5 (Sep 23, 2019)

  • Bug fixed a Windows problem with relative paths in reel files. They would show as empty filenames.
  • Bug fixed a Windows startup hangup when loading several short clips (usually in a reel file).
  • Made stereo cache be brighter green.
  • Made EDL playback work better on same clip divided with cuts in between.
  • Tightened EDL cuts to the first and last frames of the clip. Previously, sometimes the last frames would get skipped or the clip would go on an endless loop.
  • Minor sped up with clips that have timecode tracks in them. ffmpeg ignores them and so do we.
  • Updated to latest ffmpeg, which makes it compatible with truehd audio on mp4 containers.
  • Bug fixed IN/OUT points when in Timeline Shortened Display and when in Timeline Hilited Display. You can use the S/E buttons to set the in/out points. Note, however, that setting them while playing the clips can lead to hanging mrViewer.
  • Added missing flags from v4.x ( -b, -P, --stereo-input, --stereo-output, etc ).
  • otio->reel converter now keeps the name of the file in the Checkered images. This allows distinction of files not found.
  • Missing frames in sequences now do not stop playback with an opengl error. They work as set in the Preferences (black, use last frame, or use last frame scratched). This was a regression from an old version of mrViewer.

New in mrViewer 5.2.4 (Sep 12, 2019)

  • Tightened the last/first frames of sequence loops as they were sometimes letting another frame pass.
  • THIS IS EMBARASSING:
  • Bug fixed playback of sequences when not in EDL.
  • When stopping the sequence would reset to frame 1.
  • This was supposedly fixed in v5.2.3 but a re-release caused it to revert to the previous wrong behavior.
  • Temporarily fixed a crash on loading stereo exrs with different data windows on each frame.

New in mrViewer 5.2.3 (Sep 9, 2019)

  • Bug fixed playback of sequences when not in EDL. There were two problems: one when stopping the sequence would reset to frame 1 and the other was that the sequence would not get played in full and it would loop earlier.

  • Bug fixed fit ('f') algorithm in the EDL timeline.

New in mrViewer 5.2.2 (Sep 7, 2019)

  • Fixed EDL playback when changing clips and seeking manually.This would often not work and the clip would start at the beginning.
  • Fixed EDL playback for good. This was needed to have the otio adapter work well.
  • Made all PAL/NTSC Color Bars, Checkered, and Luminance/Linear images be playable.
  • Fixed a huge memory leak in the reel window's thumbnails creation. This also effected the EDL Window's thumbnails.
  • Added Fit image to Reel window. By default the key is 'f' and fits the selected image in the reel.
  • Made the viewer turn off screen savers to avoid playback from stopping or the viewer from exiting. Note that this does not effect Power Saving on Linux.
  • First beta release of .otio <-> .reel adapter. This is anOpenTimelineIO adapter to work with that EDL format which is now part of the Academy. Note that in order to work, it requires ffprobe to be on your PATH.Limitations of the current adapter are: no retiming, no dissolves or transitions, no stacked tracks (they are flattened to a single track), limited audio support.

New in mrViewer 5.2.1 (Aug 27, 2019)

  • Bug fixed looping movies showing some random frame at the end of the loop. Problem introduced in v5.1.2.
  • Fixed the bug that resulted in playback problems once the loop end was removed (like hitting the E button twice - once to set it, once to remove it).
  • Fixed the crash in the EDL window when using the LMB to drag a clip.

New in mrViewer 5.1.3 (Jul 11, 2019)

  • Made preferences always select and show User Interface first.
  • Fixed a crash when switching versions of movie files with the image info window open.
  • Fixed auto playback to always start when loading any video or sequence, not only on the first video/sequence. This would work intermittently previously.
  • Made EXR images' metadata set lut damage only on the first frame of the sequence, not on all frames as before. This avoids a whole list of information messages about lut already created.
  • Upgraded mrViewer's reading of Camera RAW formats by using OIIO instead.
  • Upgraded ffmpeg to the latest version.
  • Made Images/Labels in reel window not have a background. This allows easily seeing what image is selected by having the background yellow.

New in mrViewer 5.0.9 (Jun 16, 2019)

  • Removed a silly crash on exit usually during playback of EDLs.
  • Fixed removal of clips from the reels when the reel is not the first one. Previously, this would work sporadically.
  • Added support for audio files named with numbers in them. Previously, they would get read as sequences.

  • Fixed 16 bit movies with unsigned short pixel types.
  • Fixed alpha channel of 16 bit movies.
  • Removed F (C in Spanish) from frame display, leaving only the one of the popup menu.
  • Made auto-playback be the default setting on new installs.
  • Removed dead code of copy of boost threadpool in core directory.
  • Fixed volume display on Linux. Now the audio slider reflects the current volume at startup when the movie is loaded.

New in mrViewer 5.0.7 (Jun 4, 2019)

  • Made videos with two video tracks support stereo viewing, without needing to be the same length or fps.
  • Removed libstdc++.so from Linux distribution as it was causing problems with deepin AMD drivers.
  • The FLTK but with CTRL+ALT hotkeys was traced to a bad Linux configuration which can be corrected with xmodmap.
  • Bug fixed some memory trashing upon program exit.
  • Removed .cg shaders as NVidia has discontinued them.
  • Made shaders work with 4 channels on videos that have alpha in them and are not rgba (YCbCrA and YByBrA shaders).
  • Made Linux shortcut belong to user 1000 of the machine instead of root. This removes the message about the program not being trusted.
  • Removed a1.0.0 versioning from CTL transforms.
  • Made CTL transforms appear in media info list, as they were missing.
  • Removed libfontconfig.so.1, libfreetype.6 and libz.so.1.2.8 from distro as it was causing problems with Fedora 29/30 (slowdowns and a linker error about FT_Done_MM_Var).
  • We switched to a more modern Linux compiler to be more compatible with current distros. This means that if you are using an old distro (older than 6 years, I would guess) you might need to upgrade.

New in mrViewer 5.0.6 (May 27, 2019)

  • Made custom file requester load icons faster and be more interactive.
  • Improved the interaction of the TAB hotkey in the custom file requester.
  • Made progress report colors be readable in the black scheme.
  • Made ask/alert questions use mrv::fl_choice/fl_alert instead for color scheme and better layout.
  • Removed white background from a number of windows.
  • Bug fixed hotkeys which were acting out. Note that there's an FLTK bug with CTRL+ALT+key hotkeys, at least on international keyboards. This can be seen in the keyboard demo of fltk. - Bug fixed OCIO second display transform.
  • Made OCIO respect active_views and active_displays in ocio config file.
  • When OCIO is on, the gamma defaults are now removed from the pull down menu.
  • Bug fixed scaling up and down of the Reel window, getting corrupted or resizing incorrectly.

New in mrViewer 5.0.5 (May 17, 2019)

  • Removed a minor memory leak in decode_image when packet could not be decoded.
  • Bug fixed an FLTK menu bug which would change the text of the main menu popup and replace them with the color channel names when images changed (like in EDL playback).
  • Bug fixed a missed frame error when the videos were stopped in their last frames while in EDL playback.
  • Incorrectly called SHIFT+r to reset all changes in the image in v5.0.3, when in fact it is SHIFT+c.

New in mrViewer 5.0.4 (May 12, 2019)

  • Quick bug fix for EDL playback (got it wrong on v5.0.3).

New in mrViewer 5.0.3 (May 11, 2019)

  • Bug fixed installation of mrViewer on international characters like umlauts.
  • Bug fixed pixel query position on Windows.
  • Made CTRL+Drag gain use exposure instead.
  • Bug fixed EDL playback. Regression from 4.x.x.
  • Added SHIFT+r to reset all gamma/gain changes to the image.

New in mrViewer 5.0.2 (May 8, 2019)

  • Made Media Info's Remove Attributes work in nested attributes as well as flat attributes.
  • Improved the look of the color area window.
  • Made RMB Menu show up when media info window is open. Previously, only the main titles would show up and it would not allow anything to be selected.
  • Bug fixed Start and End frames to show secs/time/timecode when those options are selected.
  • Bug fixed Start and End buttons to select timeline display. (Regression from 4.4.7).
  • Made movie files return the attributes of their first frame only. Previously, opening the media info window in some other frame than the first one would not show any metadata.
  • Bug fixed all menus and widgets to support internationalization (Spanish currently).
  • Prettyfied some windows (about, hotkeys, keyboard).
  • Made open image open in the last directory opened (even if it was from DnD).
  • Bug fixed fullscreen and presentation modes on network connections. Previously, they would crash the viewer.
  • Made timeline, pixel bar and topbar hide properly from the preferences. Restoring them also works, but the top bar shows up a little of white area (three rows at the bottom after several show ups).
  • Gave the Black color theme some love. Now it looks much nicer.
  • Made the CTRL+Drag gain adjustment be more sensitive.
  • Added CTRL+SHIFT+Drag to adjust gamma.

New in mrViewer 5.0.1 (May 2, 2019)

  • Bug fixed connection editor failing on LMTs.
  • Bug fixed refresh windows when selecting a long ICS menu.
  • Improved reporting of .xml files as recognized.
  • Allowed metadata to be read and shown on a per frame basis. Previously, only the first frame would get shown.

New in mrViewer 5.0.1 RC5 (Apr 28, 2019)

  • Improved the fix to the Presentation mode. Now switching back and forth keeps and removes the top bar, pixel bar and bottom bar.
  • Bug fixed a crash on start up due to missing fonts.
  • Bug fixed a crash on OCIO due to missing ICS.
  • Bug fixed a memory crash on OCIO picker.

  • Fixed the listing of CTL transforms in the media info window.

New in mrViewer 4.4.6 (Mar 18, 2019)

  • Bug fixed histogram, color area, vectorscope and waveform to work with image sequences.

New in mrViewer 4.4.5 (Mar 2, 2019)

  • Bug fixed thumbnails in our own file requester which was crashing the viewer in beta-2.
  • Bug fixed saving of files creating empty entries in reels when in relative mode and files are into different drives on Windows.
  • Bug fixed crash in custom file requester when showing movies or music.
  • Bug fixed crash when loading music.

New in mrViewer 4.4.4 Beta 2 (Mar 1, 2019)

  • Fixed loading single images as they were not being loaded nor they were not being color corrected properly (OCIO/CTL).
  • Bug fixed RAW loader.

New in mrViewer 4.4.4 Beta 1 (Mar 1, 2019)

  • Reworked loading of image sequences to take advantage of threads. Now one idle thread caches images while playing. This seems to work very nicely with multipart OpenEXRs and with small (< 2K) 8 bit PNGs, IFFs, etc. This is a first beta with the new algorithm. Please report successes or failures.
  • Bug fixed crash when stereo-output/input command line option was unknown.
  • Bug fixed MMB+drag to drag canvas around. ALT+Shift+LMB remains the same and does the same.

New in mrViewer 4.4.3 (Feb 8, 2019)

  • Bug fixed loading of tiff files due to a library conflict on Linux.

New in mrViewer 4.4.2 (Feb 2, 2019)

  • Bug fixed playback/cache of sequences when frames did not begin at 1
  • Documented all commands in the connections section of the manual
  • Updated color management docs to talk about OCIO.
  • Removed a bunch of SCOPED_LOCK( _mutex ) which were unneeded
  • Made detection of sequences on disk more reliable

New in mrViewer 4.4.2 (Feb 2, 2019)

  • Bug fixed playback/cache of sequences when frames did not begin at 1.
  • Documented all commands in the connections section of the manual.
  • Updated color management docs to talk about OCIO.
  • Removed a bunch of SCOPED_LOCK( _mutex ) which were unneeded.
  • Made detection of sequences on disk more reliable.

New in mrViewer 4.4.1 (Jan 23, 2019)

  • Bug fixed Connections to work on all (?) commands.
  • Bug fixed Connections to not use relative paths in image names. Full paths are passed instead. This fixes the problem of two mrViewers started at different locations.
  • Several minor bug fixes to preload caching. Now precache reel and gui reel are different variables.
  • Added draw, erase, text, move picture hotkeys. They are SHIFT+first letter of the tool. Area selection remains as SHIFT+Drag.
  • Several minor bug fixes to BG playback.

New in mrViewer 4.4.0 (Jan 11, 2019)

  • Bug fixed BG playback of movies and sequences. It is now possible to have a FG image and comp it on the background and have it loop correctly when the FPS and length match.
  • This was a regression from some older version.
  • Added reel number in brackets of the clips being played on the title of the window.
  • You currently cannot put an EDL in the background and have it play/loop correctly. It will hang the viewer. For that reason, mrViewer will turn off the EDL in the background.
  • Added a shortcut to change pen size. This shortcut takes effect only when in draw or erase mode.
  • By default it is [ and ].

New in mrViewer 4.3.9 (Jan 4, 2019)

  • Made ghosting be a global setting instead of a per shape setting. This allows easily changing the previous/next ghosting value and see the result in real time.
  • Added "Ghosting <previous> <next>" to list of reel commands to control the ghosting of previous/next frames. Note that even thou it is a reel setting, only one setting is valid per session (the last loaded).
  • Improved OpenGL compatibility by drawing lines and points with polygons and circles respectively.
  • Increased the size of the eraser.
  • Made swing looping work on a single image when loaded with no background.
  • Removed a crash in EDL when two sequences were played and transitioned one from the other.

New in mrViewer 4.3.8 (Dec 28, 2018)

  • Bug fixed saving of shape in reel due to a typo (&d instead of %d).
  • Fixed playback of videos hanging up due to mutex lock in ping-pong (swing) playback.

New in mrViewer 4.3.7 (Dec 23, 2018)

  • Made showing and hiding of windows be a command. This makes them thread safe.
  • Bug fixed networking to work with multiple clients. Previously, only one server and one client were accepted. Now a single server can have many clients. - Removed a nasty bug in the shaders' use which would trash memory. This would make images appear green or gray sometimes. It would also not show BG images when it should. - Added previous and next frame counters to grease pencil drawing shapes. This replaces the single forwards/backwards toggle that was there before.
  • Made file requester of saving of reels start at the location of the first image loaded, instead of the current location. - Made saving of reel support saving the contents of the reel in relative path mode. - Added a Saving tab in the Preferences and two options to control the last two changes.

New in mrViewer 4.3.6 (Dec 14, 2018)

  • Bug fixed limiting of images for formats without a display window ( png, jpg, etc). Now memory setting works for them too, not just for exrs.
  • Bug fixed memory limit in win32 to handle cases of out of memory elegantly. An out of memory will limit the Gb of frames automatically.
  • Bug fixed network connections to be thread safe. Now they work as they should. There are some missing commands that it won't handle yet, but most functionality is there.

New in mrViewer 4.3.5 (Dec 7, 2018)

  • Bug fixed CTL RRT transform not getting selected when it was selected thru the menus. The 8bits, 16bits, float, etc. would work fine.
  • Bug fixed audio scrubbing which would, in latest versions, not work completely right.
  • Preload cache now works correctly when auto playback is off.
  • Bug fixed Windows' NVIDIA driver bug showing images with upped gamma.

New in mrViewer 4.3.4 (Nov 21, 2018)

  • Bug fixed cache sliding when it was stopped near the end of a sequence that did not have all frames cached. This was a Windows problem.
  • Bug fixed cache looping. Now the preload cache wraps around the end and starts at the beginning again when it is stopped near the end.
  • Made startup time be much faster, as it now does not load any frames until the GUI is up and idle.
  • Made background image show on first run if it is different than foreground image. Note that this makes the gui a tad slower on start up.

New in mrViewer 4.3.3 (Nov 12, 2018)

  • Bug fixed EDL playback as it had gotten broken with the new timeline algorithm. - Playback of BG images works only when the FG caches are full or, alternatively, when not using cache nor play all frames.

New in mrViewer 4.3.1 (Oct 29, 2018)

  • Reverted saving of movies with audio.
  • This had gotten broken when the display of in/out in the timeline was added.
  • Note that saving with audio has some problems in some rare movie files that create very short gaps (stutters) in the audio.
  • Also, saving movies with audio is slow. It is recommended you use the ffmpeg standalone that ships with mrViewer for any sort of complex audio manipulation.
  • Added libx265.so to Linux distribution as it was missing.
  • Made S/E buttons set the in and out points of the movie that is to be saved.
  • Made Linux distribution not use rpath anymore in any of its libraries. This makes sure LD_LIBRARY_PATH works correctly.
  • Updated utils/libs.rb accordingly to do it automatically.
  • Made GLSL shaders compatible with Mesa library on Linux, as they were reporting a bunch of errors.

New in mrViewer 4.3.0 (Oct 21, 2018)

  • Made loading of sequences much more interactive and faster. Now the GUI does not lock itself as much.
  • The option of missing frames now is more interactive. It only needs to clear the cache to refresh the image gaps. There's no need to quit mrViewer.

New in mrViewer 4.2.9 (Oct 12, 2018)

  • Added an option in Preferences->Loading to select how missing
  • frames are displayed. Currently, the options are as a black
  • frame, as a repeated frame, or as a repeated frame with a red
  • cross in the middle.
  • Updated libraries to latest OpenEXR (v2.3).
  • Bug fixed an incompatability issue with the FFMPEG libraries
  • by upgrading to latest Zeranoe libs.
  • Updated OIIO to latest libraries (libjpeg-turbo, libpng1.6.35).

New in mrViewer 4.2.8 (Oct 4, 2018)

  • Added %ENVVAR% and ${ENVVAR} support to OCIO environment variable.
  • The two syntaxes work on both platforms. This allows the OCIO
  • variable to be defined, like this example:
  • under Linux syntax:
  • $ export OCIO=/mnt/show/${SHOW}/${SHOT}/ocio/config.ocio
  • or in Windows syntax:
  • $ setx OCIO 'D:/show/%SHOW%/%SHOT%/ocio/config.ocio'
  • and then set SHOW and SHOT in the environment that calls mrViewer.
  • Made HDR shader show when _has_hdr is set. This variable is only
  • set when the shader type is GL.
  • Made HDR shader reset itself on new image foreground. Currently,
  • it is not possible to have a YCbCr shader in the foreground
  • (HDR10, for example) and a different one in the background (SDR).
  • Bug fixed a bug in looping that got introduced in v4.2.5 and was
  • NOT fixed in v4.2.6. Now loop works correctly instead of continu-
  • ing on sometimes, after the last frame.

New in mrViewer 4.2.7 (Sep 25, 2018)

  • An identical release to v4.2.6 but adds some missing DLLs in the Windows releases.

New in mrViewer 4.2.6 (Sep 24, 2018)

  • Bug fixed a bug in looping which got introduced in v4.2.5.
  • Bug fixed audio sync in stepping or scrubbing. Previously, they
  • would repeat the audio frames.
  • Added support for multithreading decoding of video in movies. This
  • is needed to play 4K movies in real time. The setting of automatic
  • threads is 0 in Preferences->Video->Number of Video Threads.
  • Added support for HDR10 movies. They need the 16-bit toggle in
  • Preferences->Loading and must use OpenGL shaders
  • (export MRV_SHADER_TYPE=GL).
  • Since these movies are 4K, you should also watch them with 0 video
  • threads (auto video threads).
  • This is a beta feature. We need to know if it creates some problems
  • in the compiling/linking of the shader under different gfx cards,
  • as we are trying to use the lowest compatibility layer possible.
  • Bug fixed BT709 matrix.

New in mrViewer 4.2.5 (Sep 5, 2018)

  • Improved cache significantly by changing its algorithm. Now OIIO loading works much responsive and faster.

New in mrViewer 4.2.2 (Jul 29, 2018)

  • Added interpreting foundry's YCbCr metadata for matrix transformation. Currrently, this leads to Rec 709 being added in the mrViewer color pipeline.
  • Bug fixed out of memory errors to not crash the viewer.
  • Changed caching to a new algorithm that works better and faster. It allows caching large scale images with audio, as long as memory is available to handle all the frames. It also allows jumping into the cache while playback is on.
  • Bug fixed memory cache for videos not being loaded properly from the preferences file.

New in mrViewer 4.2.1 (Jul 16, 2018)

  • Bug fixed a minor memory trashing in ICC browser.
  • Added back subtitles on Linux as ffmpeg was being compiled without libass due to a change in the ffmpeg Makefiles.
  • Improved performance of video decoding for yuv444p10le, which had gotten worse in v4.2.0.
  • Removed most tsan (thread sanitizer) warnings.

New in mrViewer 4.2.0 (Jul 1, 2018)

  • Bug fixed versioning with prefix of v only and matching movie files, like test.mov. The substring would index beyond the file size, aborting the program.
  • Bug fixed printing specifier in memory display ( PRIu64 instead of PRId64 ).
  • Removed a memory leak when changing image version due to thumbnail image being left behind.
  • Bug fixed precache when gaps are found as this got broken along the way when adding the code to versioning.
  • Bug fixed precache when first frame was not 1 for OIIO.
  • Bug fixed auto reloading of frames when the format was one of OIIO.
  • Bug fixed scrubbing getting turned off after using the drawing tool.
  • Bug fixed a bunch of tsan (ThreadSanitizer) warnings.

New in mrViewer 4.1.9 (Jun 23, 2018)

  • Removed a subtle bug in looping images that did not start at 1. The result would go unnoticed, but internally a wrong frame would get carried.
  • Made a second attempt at FFMPEG jpg/png/dpx loaders. With the fix above, all seems correct. You can now switch from FFMPEG, to OIIO or to ImageMagick.
  • Bug fixed a race condition in OIIO readers which could crash the viewer. This would mostly be seen when loading DPX files with the layer menu/shortcuts creation.
  • Made OIIO readers the default readers as they handle 10 and 16 bit images correctly and image sequence gaps.
  • Made versioning support _v with no version number and not interpret it as 0, but just skip it.
  • Bug fixed versioning for prefixes different than 2 characters.
  • Bug fixed Favorites listing in FLU file requester. Now they are listed in several columns if there are too many. Previously, they would get listed in a single column and scrolling would corrupt the view.
  • Added this HISTORY.txt file and the LICENSE.txt file to the docs/ directory.

New in mrViewer 4.1.8 (Jun 16, 2018)

  • Added .rgbe and .hdri as valid HDR image extensions.
  • Added versioning to the sequences/movies.
  • This allows to handle clips of the same shot, but different versions as one object. For example, if you place a clip with .../SHOT001_v005/SHOT001_v005.%04d.exr in the reel/timeline, and there is another sequence with: .../SHOT001_v008/SHOT001_v008.%04d.exr on disk, you can step through versions by pressing ALT+PgUp (previous version) or ALT+PgDown (next version).
  • The version number is found by a prefix, by default '_v'.
  • This can be changed in the Loading section of the preferences.
  • Note that the version numbers cannot be more than 10 numbers apart by default. This can be changed in the
  • Preferences->Loading->Max Frames Apart section of the preferences.
  • Bug fixed a movie playback problem that was introduced in v4.1.1. Looping would not work properly with some movies and you'd get a decode error on the first frame of the movie file.
  • Bug fixed a bunch of issues in the EDL / BG image playback.
  • Reverted the use of FFMPEG for PNG/JPG loading as it was not caching properly. Some frames would get repetitions.

New in mrViewer 4.1.7 (Jun 10, 2018)

  • Switched to OIIO's HDR image loader and saver as it is more robust than the original Radiance one I was using.
  • Added HDRI saver.
  • Made HDRI saver allow saving a crop region of the view (smaller data window than display window).
  • Bug fixed EDL editing start and end frames shifting.
  • Made PNG/JPG FFMPEG reader work properly once the images were cached. Now it works realtime with images that are 4K once they are cached.
  • Reverted naming convention to not use the YYYYMMDD format in archive name, as it was making other web pages not able to link to the download directly.
  • Bug fixed chocolatey with the old and new naming convention.

New in mrViewer 4.1.6 (Jun 4, 2018)

  • Bug fixed hdrImage.cpp which was incorrectly optimized.
  • Put back the reporting of LUTs as they are used as it was unclear before which lut was being used.
  • OIIO now has its own requester to save files. This is mainly to support MipMap saving to .tx files.
  • OIIO now has faster loading of tiff files.
  • Bug fixed installer to make it show the icon once again on Linux.
  • Re-added Libraw to oiiotool on Windows. Sent the changes to github.

New in mrViewer 4.1.3 (May 21, 2018)

  • Native file requester on Windows does not leave their menus open
  • and obstructing the view.
  • Previous channel hotkey now works correctly on Color channel when
  • this channel is in the middle of the channel list.
  • Previous channel hotkey now works correctly on Color channel when
  • the following channel would be alpha overlay (no more than RGBA
  • is loaded).
  • Previous channel hotkey now works correctly on Color channel when
  • the following channel would be a lumma (RGB or Y,RY,BY only is
  • loaded).
  • Bug fixed IFF image reader to work as all other image readers,
  • reading the header chunk on each fetch. Improved the fetching to
  • only fetch once instead of twice as before.
  • Made all shortcuts be a toggle (Z, N, C, R, G, B, A, L and V)
  • between their counter parts and the previously selected channel.
  • Made image switching keep the layer selected when possible. Note
  • that this feature does not always work particularly when toggling
  • the shortcuts (specially when dealing with multipart openexrs),
  • so it should be considered alpha.
  • Made use OCIO button be like the rest of the buttons instead of
  • a gray one.

New in mrViewer 4.1.2 (May 18, 2018)

  • Updated FFMPEG to a later (almost latest) version.
  • On Windows, the file requester is the native one by default now. This effects both loading and saving. Note that if you have preferences saved, you will need to remove it for this to take effect or save a new preferences with the native switch on.
  • Bug fixed EXR saver to not repeat main layer name twice and breaking the multipart saving.
  • Improvements to channel/layer usage per request from Dominik Pott:
  • Next/Previous channel hotkeys are less granular. They now jump RGBA channel groups.
  • Switching to the Z channel no longer breaks the hotkeys of RGBA.
  • Channel names are now sorted according to function (ex. XYZ, RGB, etc ).
  • Precaching now starts from the current frame, not from the start.
  • Changing channels past the last or first channel loops to the beginning and to the end channels respectively.
  • There's a new hotkey (e) to toggle two channels for easy comparison.
  • The cache now respects the IN/OUT points in the timeline and won't cache further than that, except it has already been cached.
  • The hotkeys have been changed so that 'c' always brings you to the color image, while r,g,b change based on what group of channels you have selected ( N, P, etc ).

New in mrViewer 4.1.1 (May 8, 2018)

  • Bug fixed switching FG/BG images where the start/end frames were different. Previously, this would lead to a hang.
  • Improved playback of short FG in loop with a long clip in BG. Previously, this would lead to a crash or to a mutex lock.
  • Removed the final code in time2frames() which was wrong and causing havok.
  • Fixed a memory leak in loop playback.
  • Updated oiio and oiiotool to the latest prerelease version. Note that on windows 32 bits, the code does not use SIMD optimizations.
  • Added Libs that OIIO is compiled with to the About window of mrViewer.

New in mrViewer 4.0.8 (Apr 23, 2018)

  • Made HEVC saver report a HVC1 fourcc so that Apple products will recognize them and show a thumbnail.
  • Made Z Depth be reported as "Z" only, as that makes it work on different languages when saving EXRs.
  • Bug fixed Z channel selection being chosen as Color.
  • Made OIIO iff saver save only up to 16-bits, as float is not supported. Note that OIIO's IFF saver does not support Z channel.
  • Added --stereo-input flag to command-line. It works just like --stereo-output flag but for the stereo input.
  • Bug fixed X and Y flips which got broken in a previous build.
  • Bug fixed pixel aspect ratio being applied twice.

New in mrViewer 4.0.6 (Apr 18, 2018)

  • Bug fixed looping in movies with an In/Out points. Now the looping is more frame accurate.
  • Further improved playback of two video tracks as stereo 3d.
  • Improved timecode/frame, timeline widgets allowing all the shortcuts of the main image view.
  • Made LUT be on as a default option and the 8 bits OCIO default be sRGB.
  • This change is only present if starting mrViewer without preferences set. Remove the prefs file from $HOME/.filmaura.
  • It makes 8 bit formats (png, jpeg, etc) behave like expected under the nuke-default ocio config, while linear formats like HDR, OpenEXR, etc. behave also well.
  • This change is to make mrViewer behave with LUTs just as when it was using gamma 2.2 only.
  • Made Active Views' environment variable OCIO_ACTIVE_VIEWS return sRGB, rec709, Film, Log, Raw or None in that order on linux as the active_view setting in the yaml config.ocio file was not respected on that platform. This is a bug fix work-around.

New in mrViewer 4.0.5 (Mar 25, 2018)

  • Bug fixed a crash when reading corrupt EXR files.
  • Reversed the order of lut baking/gamma change in MIFF, TIFF,
  • PIC and PSD.
  • Removed a debugging message printing "f " and the frame when playback started.
  • Improved performance of ocio baking by avoiding gamma changes too, unless they are needed.
  • Added T (toggle lut) shortcut to list of shortcuts.
  • Added Ctrl+p (toggle pixel ratio) to list of shortcuts.
  • Made the S and E buttons (and the corresponding I and O shortcuts) set the start/end frame of the timeline but not byshrinking the timeline, but by highlighting the area instead.
  • This is a preference option in:
  • Preferences->Playback->Timeline->Selection.

New in mrViewer 4.0.4 (Mar 14, 2018)

  • When lut is active, saving to a MIFF, TIFF, PNG, PIC and PSD will bake the lut in the picture.
  • Made lut more verbose, printing out the lut when it is not created, too.
  • Bug fixed alpha channel presence in imagemagick wand loader. Previously, it would tag all images with alpha channel and lead to reporting of colors to 0 premult when no alpha was there.
  • Made saving of TIFF and PNG several times faster.
  • Added support for alpha channel in YUVA movies, even if a shader is not available. This allows viewing the alpha channel of ProRes 4444 movies.
  • Added saving of alpha channel when codec is prores_ks and YUV format is YUV444.
  • Bug fixed stereo display of inferior/superior which was placing both images one on top of each other.
  • Bug fixed stereo looping of image sequences. Previously the loop would not happen. Looping of two movie tracks or movies was okay.

New in mrViewer 4.0.2 (Feb 19, 2018)

  • Bug fixed GLSL 2.0 YCrCbA shader to not throw a syntax error.
  • This makes mrViewer's YUVA work with other graphic cards other
  • than NVidia (ATI/AMD, Intel, etc). Note that the YUVA mrViewer
  • pipeline has not been developed yet.
  • Added some changes to OpenGL color selection in Windows to
  • to avoid a conflict with Windows 7's Aero.
  • Removed rpath from IlmCtl and IlmCtlSimd libraries, as it was
  • not allowing LD_LIBRARY_PATH to work properly.

New in mrViewer 4.0.1 (Feb 16, 2018)

  • Bug fixed GLSL 2.0 YCrCb shader to not throw a syntax error. This makes mrViewer work with other graphic cards other than NVidia (ATI, Intel, etc).
  • Bug fixed jpeg loader (ffmpeg), to load files starting at other frames than 1.

New in mrViewer 4.0.0 (Feb 11, 2018)

  • Improved loop sync in fg/bg image playback.
  • Improved loop sync in 3D stereo playback.
  • Made loop work in time instead of frames. That allows looping properly two different videos with different fps.
  • Made a change in GLEW initialization which should improve OpenGL compatibility.

New in mrViewer 3.9.9 (Jan 23, 2018)

  • Bug fixed LUT always on by mistake which would lead to wrong views
  • Improved gamma pulldown to display all displays/views in submenus.

New in mrViewer 3.9.8 (Jan 21, 2018)

  • Added OCIO ICS/Display/View changes on a network connection.
  • Added CTL IDT/RT/ODT in network connections.
  • Bug fixed Add to Favorites in file requester as it was not
  • adding any favorites. Regression of sorting alphabetically.
  • Added ACES ASC CDL transforms to network connections.
  • Source: README.txt, updated 2018-01-20

New in mrViewer 3.9.6 (Dec 16, 2017)

  • Solidified Window's maximize button to also work when the taskbar is not at the bottom of the screen or is of diferent size as default.
  • Added a command-line option to start the video/image playing. The shortcut is -P and the full option is --playback.
  • Detected JPEG file format with ffmpeg instead of with ImageMagick, as the reader is faster and can read more bitdepths.
  • Made Favorites pulldown and window report the files in alphabetical order.
  • Bug fixed Favorites pulldown in file requester as it was broken.
  • Bug fixed compositing when resize is on. It was not scaling the image properly in most cases.

New in mrViewer 3.9.5 (Dec 6, 2017)

  • Made cache preloading's default to on. This will take effect only if you open a fresh mrViewer with no preferences saved.
  • Made message when selecting an ocio input color space based on bit depth a tad more clear. It is now reported what bit depth it selected as default.
  • Made Preference Window's Revert/Cancel/Save buttons more clearly visible
  • Bug fixed maximize button on Windows which would place the window below the taskbar.
  • Bug fixed picking an OCIO config from the 3D LUT preference when another has been selected previously.

New in mrViewer 3.9.4 (Nov 29, 2017)

  • Bug fixed Video timecode not being read in Spanish locale.
  • Made SHIFT+LMB + drag draw a selection area (temporarily switching from Scrub mode).
  • Made tooltips in input color space report useful information.
  • Ported video and audio to latest FFMPEG API. This change should go unnoticed to the user.

New in mrViewer 3.9.3 (Nov 22, 2017)

  • Removed incorrect message about OCIO default for an image.
  • Added message of OCIO default and OCIO taken from name of image.
  • Made all shaders calculate gain before lut. This allows exposure
  • to work correctly.
  • Made all color calculations (color picker, color area, vectorscope
  • and histogram) take gain before lut to allow for exposure to work
  • properly.
  • Made input color space be taken from image filename following
  • Sony's conventions.
  • Bug fixed RY/BY/Y channel selection in luminance/chrominance
  • images. Regression from an old version of mrViewer.
  • Bug fixed color values showing as NANs when alpha was 0 due to
  • unpremult.
  • Added tooltips to ICS pulldown.

New in mrViewer 3.9.2 (Nov 19, 2017)

  • Fixed 'h' (Center Image) when the image was straight. Regression from 3.9.1.
  • Fixed Text tool in Linux. Previously the text would not appear at all or it would show as black squares.
  • Made OCIO Lut be a 3 channel lut, while CTL remains a 4 channel lut. This saves some memory and calculation time when using OCIO.
  • Made OCIO Pick button in the Media Info window also update the OCIO Input Color Space pull down.
  • Made mousewheel in pulldown menus a no-op to avoid hanging.
  • This required a change in fltk's Menu_popup.cxx to set MODAL to false.
  • Fixed move picture tool to move also the data window.
  • Fixed Masking and Safe Areas on rotation of image.
  • Fixed OCIO default scene_linear which would not appear in the ICS popup menu as selected when it was the default space.
  • Added hotkey (SHIFT+i) to toggle Input Color Space popup and fstop controls when Use OCIO is in effect.

New in mrViewer 3.9.1 (Nov 15, 2017)

  • Improved fixed pixel color when alpha was set to 0. mrViewer
  • would incorrectly do a premult of the alpha. Regression of
  • v3.9.0.
  • Cosmetic change. Gamma button will no longer display long
  • transform view names and will truncate them to the widget size.
  • Gamma button will always display the current OCIO view
  • transform.
  • Bug fixed alpha display in Area Color Information. Previously
  • it would always display it as black.
  • Fixed CentOS 7 compatibility by including libstdc++ and
  • libgcc_s DSOs to the distribution.
  • Added an Optional Image Color Space pulldown to the top
  • toolbar. It is activated when using ocio and the option
  • to the toolbar has been selected in the LUT->OCIO preference.
  • Bug fixed sequences of numbers.ext only, like 00001.exr, 00002.exr,
  • etc. Both the command line as well as the file requester now
  • support them.
  • Added an "inputColorSpace" attribute to EXRs to save out/load in
  • the input color space.

New in mrViewer 3.9.0 (Nov 13, 2017)

  • Bug fixed coordinate system for drawing, selection, safe areas, etc
  • Bug fixed off by 1 in mouse coordinates.
  • Added support for OCIO's Views to be accessed directly from the gamma pulldown. As a convenience, when an OCIO view is selected the LUT button is turned on and the gamma is set to 1.0.
  • Made OCIO's default config be nuke-default's, which now ships with mrViewer.
  • Fixed selection rectangle.
  • Added 90 degree rotations to the images. There's no image format that sets them. It is just a user hotkey and menu. They can be used together with flipping of images. However, rotations cannot yet be used with images that have data_window != display window. Also, area selection does not work properly on rotated images.

New in mrViewer 3.8.8 (Nov 8, 2017)

  • Bug fixed reversed coordinates as done in v3.8.6 as it was causing problems with area selection and with exr's with data window != display window.
  • Added https://youtu.be/BLX9Pwcny2c OCIO video tutorial.

New in mrViewer 3.8.7 (Oct 29, 2017)

  • Improved detection of .hdri images to support those saved from Photoshop (#?RGBE instead of #?RADIANCE).
  • Removed error when creating thumbnails of RAW formats.
  • Added support for mipmaps in .tx files. Now Media Info Window has a slider to change mipmap levels.
  • Removed crash in Clone Image when cloning a previously cloned image.
  • Added some partial EXIF data support to rawImage formats.
  • Added all metadata in .tx images.
  • Updated About messages to include OpenColorIO, OpenImageIO and Libraw copyrights and versions.
  • Added a Pixel Toolbar tab in Preferences to control how the pixel toolbar behaves on startup.
  • Updated documentation to reflect latest changes.

New in mrViewer 3.8.6 (Oct 24, 2017)

  • Bug fixed GLSL shaders to support scale and offset.
  • Removed a syntax error in GLSL rgba shader.
  • Added support for CR2, DNG, NEF, RAF formats through libraw.
  • Added support for Arnold's .tx format thru OIIO on Windows.
  • Reversed coordinate system to make it compatible with Nuke and Natron. Now 0,0 is the bottom left corner insted of the top left corner.
  • Updated to newer compilers. On Windows, VC2015. On Linux, gcc-4.9.

New in mrViewer 3.8.5 (Oct 14, 2017)

  • Added tooltips to all OCIO color spaces and to the Config line.
  • Allowed changing OCIO config file from the Preference window.
  • Added a button to toggle OCIO on and off. By default, it is on.
  • Added the environment variable MRV_OCIO_8bits_ICS, MRV_OCIO_16bits_ICS, MRV_OCIO_32bits_ICS, MRV_OCIO_float_ICS to control the default input color space for the corresponding type of image depth.
  • For OCIO to perform better, it is recommended you use a 64x64x64 lattice and a num stops of 8. mrViewer will set that to the default when loaded the first time.
  • Made the ODT.Academy.RGBmonitor_D60sim_100nits_dim the default ODT for CTL.

New in mrViewer 3.8.4 (Oct 8, 2017)

  • Add a CUBE regex line in cube2ctl.rb/py for compatability with some cube luts.
  • Added Move Picture Tool to the Action's toolbar. This tool allows moving the pictures in the canvas to, for example, position two shots side by side.
  • Currently, only two images can be placed (front and back).
  • Added OCIO support. Currently this means it reads the OCIO environment variable, and a new RMB menu called OCIO appears, while all the CTL/ICC menus disappear.

New in mrViewer 3.8.3 (Sep 29, 2017)

  • Made choco uninstall remove the mrViewer directory.
  • Improved bug error reporting of different ODTs when loading one incompatible from the ACESclip file. Now the message names both ODT names.
  • Added TIFF with JPEG support to ctlrender standalone executable on 64 bits Windows. Bug fixed a crash in presentation mode (F12).

New in mrViewer 3.8.2 (Sep 25, 2017)

  • Added Actions to Preferences. With them you can select the action that opens at start-up (scrubbing, drawing, color area selection, etc).
  • Added hotkeys to all window popups (F4-F9). You can, for example, pop up the reel window with F4, the media info window with F5, the Color Area Window with F6, The Action Window with F7, the 3D Stereo VR360 options with F8 and Preferences with F9.
  • Reverted back to VC2013 on Windows, to make the compilation work under Windows 7 and Vista. Windows 7 was broken due to the switch to VC2015 (which would compile with the 10 SDK).

New in mrViewer 3.8.1 (Sep 17, 2017)

  • Made Scrubbing work with the left mouse button only. The default behavior of the left mouse drag is now scrubbing. There's no need to use SHIFT/CTRL combo. You can use the Action Tools Window (renamed from Paint Tools Window) to change it back to area selection, draw pencil, draw text or eraser, besides scrubbing. Removed the scrubbing shortcut.
  • Removed work-around for subtitles with ' as a sea of backslashes quotes the file just fine. Same with file paths with : in them.
  • Bug fixed adding subtitles to audio files only. This is not allowed.
  • Added missing movie extensions to file requester. Now: asf, avc, avchd, m2ts, m2t, ogm, ogv and ts are listed as movie files. Previously, they would be hidden.
  • Made file requester list appropiate files for file extensions when the file requester has already been opened once.
  • Made the EDL timeline follow the viewer's timeline so it will show the current frame when the EDL Window is opened.
  • Made EDL Edit window support PageUp/PageDown shortcuts to go to the next or previous image sequence/movie.
  • Made Compositing->Scale the BG image to the FG image size, when unselected, place the BG image in the center of the screen, instead of in a corner.
  • Made SOP GUI hide when in presentation mode.
  • Made SOP LUT update when switching images with different LUTs.
  • Made SOP GUI update when switching images.

New in mrViewer 3.8.0 (Sep 7, 2017)

  • Bug fixed cutting of clips in EDL Window leaving the right clip
  • with no audio.
  • Changing OpenGL Blend Mode in Preferences now updates the view
  • interactively, without having to press OK.
  • Bug fixed 3D Stereo view when in VR Sphere mode. Previously,
  • moving the view would only move one eye (leaving the cyan, for
  • example, in the same place). This was a regression from v3.7.8.
  • Made preferences a tad more pretty (boxes aligning, etc).
  • Allowed loading of subtitles from the command-line
  • ( -u <srtfile> or --sub <srtfile> ). It can be specified
  • multiple times to load subtitles for multiple movies. Only one
  • subtitle per movie is allowed.
  • Made subtitle appear on both images of a stereo video when the
  • stereo comes from two movie files or a movie with two tracks.
  • Previously only the left eye would show subtitles.
  • Movies which encode both stereo images in a single image
  • (top/bottom, left/right) do not yet work.
  • Made Preferences->Auto Refit Image more intelligent. When
  • switching images with PgUp/PgDown they will not refit themselves
  • if zoomed and the two images have the same display window.
  • Previously, if Auto Refit was set in the preferences, the refit
  • would happen regardless.
  • Made maximum zoom reach x64 times to match the small resolution
  • of some samples in ffmpeg.
  • Added support to encoding in subtitles in the
  • Preferences/Subtitles, to allow for subtitles in different
  • languages other than English. ISO-8191-1 and UTF-8/16
  • are supported. You can also type in the encoding yourself.
  • Added a work-around to play subtitle files with ' in their names.
  • Basically, the subtitle is copied to $TEMP without the '.

New in mrViewer 3.7.9 (Aug 25, 2017)

  • Allowed saving movies in all formats, not just avi, mov and wmv. This includes mkv, ogv, etc.
  • Added support for x265 (HEVC) saving ( Profiles Main, Main10 and RExt ). Loading was already working.
  • Made the movie and image saving popup windows appear on the center of the screen, instead of randomly placing it.
  • Made profiles change when the codec is changed in the movie saving window. Now the profile reflects the available profiles for a codec.

New in mrViewer 3.7.8 (Aug 16, 2017)

  • Removed filtering on VR 360 Cube to avoid seams.
  • Fixed rotation of VR360 cube/sphere when a background image was present and then turned off. Previously, the geometry would get the rotation wrong. Also, the code is now faster.
  • Added a version check to cube2ctl.rb and 3dl2ctl.rb, as they require at least v1.9 of ruby.
  • Added 192x192x192 and 256x256x256 to LUT sizes. The new sizes consume a lot of memory but they are really accurate.
  • Removed a crash on windows on an assert() of audio buffers being aligned in mrvWaveEngine.cppp. The assert was wrong as it was casting the pointer to unsignedlong.

New in mrViewer 3.7.7 (Aug 9, 2017)

  • Preload cache now works when changing channels. Previously, the cache would not get refreshed.
  • Cache is smart enough to not reload channel changes to U, V, W or R, G, B, A or X, Y, Z (albeit Z channel sometimes may trigger a reload).
  • Preferences->Positioning: Fixed Size will now keep the size of the window even when loading a large image.
  • Same with Fixed Position. It will keep the window position.
  • Made Add Attribute refresh the view window. This updates things like the timecode HUD display.
  • Added a first pass at VR 360 Cube Map. You can find it in the Stereo 3D Options panel. This setting takes a strip of 6 images as OpenEXR uses and maps them onto a cube, similar to VR360 Spherical. Note that there are currently seams in the edges of the cube map.

New in mrViewer 3.7.6 (Aug 3, 2017)

  • Added a Positioning tab to Preferences. In it, you can set the position and size of the view window so that it always opens in the same place and at the same size.
  • Added a button to take the position and size parameters from the current settings in the view window.
  • Removed crashes on network connections when the server is closed.
  • Fixed audio sync on Windows when audio channels equals one, a regression from v3.7.2.

New in mrViewer 3.7.5 (Jul 27, 2017)

  • Bug fixed audio/video scrubbing not choosing the right frames. Sorting by the pts of the packet rather than the frame would not work.

New in mrViewer 3.7.4 (Jul 24, 2017)

  • Made saving of frames in OpenEXR save out the current timecode for the frame instead of the start timecode for the sequence. This allows to keep the timecode correct regardless of frame loaded.
  • Bug fixed 1D LUTs in cube2ctl.py. Previously there were syntax errors.
  • Bug fixed audio scrubbing not working anymore since v3.7.2.
  • The audio handle limiter was set too aggresive.

New in mrViewer 3.7.3 (Jul 19, 2017)

  • Made VR360 work in network connections
  • Made VR360 not take so many CPU cycles. Now it is a light process.
  • Bug fixed a problem on Windows' audio not playing files with very fast frame rates (239.846 fps).
  • Bug fixed flipping of image in X and Y when in VR360 mode.
  • File requester allows movies with the % character in them.
  • File requester allows utf8 characters in filenames.
  • Added Compositing Tab to Preferences. You can now toggle the resizing of the background image.

New in mrViewer 3.7.2 (Jul 13, 2017)

  • Bug fixed setting image as background when it was done thru the menu in the view or reel window. Previously, the reel would not get stored and this would lead to a crash.
  • Bug fixed channel selection on network connections.
  • Bug fixed gamma setting on network connections, when switching images.
  • Added cube2ctl.py and 3dl2ctl.py. These are Python ports of the Ruby versions (cube2ctl.rb and 3dl2ctl.rb). They both work practically the same and produce identical output.
  • Fixed movie files with 3 periods in them being recognized as image sequences when the extension was unknown.
  • Fixed loading many movies and reaching the maximum of audio file descriptors.
  • Added optionally saving the metadata for movies.

New in mrViewer 3.7.1 (Jul 5, 2017)

  • Bug fixed 3D stereo playback to sync the two tracks on loops.
  • Bug fixed a sequence detection when files were called 1234.psd or 12345.psd. Now they are treated as single images, regardless. Previously, you had to turn off Preferences/Loading/Load Sequence on File Association & CommandLine.
  • Bug fixed a nasty crash in audio playback, which would appear when switching images, usually in the background.
  • Improved looping with audio. No longer audio continues in the background once the last frame is reached.
  • Bug fixed file requester on multi selections. Previously, using CTRL or SHIFT to multiselect would, in some cases, not load the files once Okayed.

New in mrViewer 3.7.0 (Jun 27, 2017)

  • Removed the difference between IPTC and EXIF data, as it was never clear. Now they are all called Metadata.
  • Made int attributes' slider in Media Info Window update when changed instead of when released, except for ripmap/mipmap attribute which remains when released.
  • Added the missing attribute types (matrices, boxes, etc) to RMB->Add->Attributes panel in the Media Info Window.
  • Bug fixed timecode parsing of drop frame timecode. Valid Examples: 00;01;00;02, 00.01.00.02 or 00:01:00.02.
  • Added support for multiple video tracks, switching them as you do with subtitles (RMB->Video->Track #).
  • Added stereo from multiple video tracks in a movie file, when they are the same resolution and have the same frames per second (fps) and duration. You still need to go to the
  • 3D Stereo Window and select the stereo output type.
  • Bug fixed video/audio/subtitle selection when the codec could not be located.
  • Added support for OpenEXR's opaque attributes. They are attributes which cannot be modified.

New in mrViewer 3.6.9 (Jun 20, 2017)

  • Added saving OpenEXRs with deep data. Note that this mainly copies the file and changes the metadata only.
  • mrViewer now retrieves all metadata from an OpenEXR file. Note that except for capDate, all attributes are loaded from the first image in the sequence.
  • Fixed Preferences->Loading->Auto loading of images when changed on disk. Previously, it was a no-op. Now it properly updates the changed image(s).
  • Added an Update Frame in Cache (shortcut 'u') to update only a single frame in the cache. It reloads the image from disk.
  • Bug fixed saving of all layers when OpenEXR image had Z and ZBack channels. Previously, this would crash.
  • Fixed saving of metadata on OpenEXR images with no layers. Previously, no metadata would get saved.
  • Fixed a regression which was making loading of multichannel OpenEXR images be too slow to update the display.
  • Added the ability to create/remove/modify the metadata of a movie or OpenEXR image. Use the right mouse button on the Media Info Window to get a menu of options.
  • Removed the saving of dpx:television gamma in dpx saving as it was gamma'ing twice the image.
  • Made the OpenEXR attribute 'capDate' be stored and update on every frame. - Improved wandImage saving to save all types of attributes in PNG and MIFF formats only. PSD, TIFF and DPX do not keep the additional attributes.
  • Note that the current fast PNG reader does not read attributes.
  • Bug fixed saving of Video attributes in movie files. Note that ffmpeg saves its own set of attributes which cannot be changed (encoder, handler, language).

New in mrViewer 3.6.8 (Jun 15, 2017)

  • Made timecode start editable in the Media Info Window. Just type a new timecode and press TAB.
  • Added creation and removal of IPTC metadata. In the Media Info Window, use the right mouse button and select Add->IPTC->Metadata or Remove->IPTC->Metadata.
  • Allowed to load images which have only a number in them, like: 2304.exr. They are treated as single images, not as sequences.
  • Bug fixed loading of images that are like: t09.exr, when the image loaded is full content, like: t10.exr. Now they are both properly recognized as t%02d.exr
  • Added an option to Preferences->Loading to allow controlling how file asocciations behave when loading a single image or loading it command line. The option is to load the whole sequence or just the image. This is similar to the Drag&Drop option in the same Preferences->Loading.
  • Bug fixed HUD Timecode display. Previously, the values were wrong.
  • Bug fixed some memory trashing on the Media Info Window's tooltips.
  • Bug fixed reading of timecode in OpenEXR pictures.

New in mrViewer 3.6.7 (Jun 9, 2017)

  • Bug fixed OpenEXR timecode ( "timeCode" attribute ) to work as said in v3.6.6.
  • Made playback not start at the point of a preloading cache, but from the cursor location (start of sequence usually).
  • Bug fixed timecode being incorrect.
  • Bug fixed Opus audio decoding, which would previously raise tons of errors.
  • Made timecode be a separate variable, instead of modifying frame directly. This means:
  • Frames, Seconds and Time do not take the timecode start into account.
  • Timecode Drop Frame and Timecode Non-Drop Frame take timecode start into account.

New in mrViewer 3.6.6 (Jun 3, 2017)

  • Added support for timecode in movies. When a movie with a header entry of "timecode", or a video stream header entry of "timecode" is found, the timecode is interpreted as an offset of the current frame.
  • Added support for timecode in OpenEXR pictures. When the tag "Timecode" is found, the timecode is interpreted.
  • Added support for m2ts (AVCHD) [Blu Ray] movies.
  • Added support for saving OpenEXRs with both Z and ZBack channels in a layer. Previously, the saving would fail.

New in mrViewer 3.6.5 (May 26, 2017)

  • Added tooltips to 3d stereo options panel.
  • Made VR360 disregard the display window and wrap the data window instead. Previously, no image was displayed.
  • Added audio support for playing Dolby TrueHD.
  • Removed error reporting while creating thumbnails. This avoids the log window to appear when an error in the thumbnail is found and then not allow closing the log window.
  • Bug fixed a start up problem on movie files where the first image frame would not get decoded.

New in mrViewer 3.6.4 (May 19, 2017)

  • Made switching images respect the playback settings.
  • Next Page and Previous Page keys switch images with playback still on.
  • Bug fixed: OpenEXR's framesPerSecond as a string value not respecting the user's locale. Previously, floating point values with a comma would get turned into floating point values with a period.
  • Bug fixed opening the viewer in a second monitor through file associations. Previously, the viewer would not open.

New in mrViewer 3.6.3 (May 13, 2017)

  • Added an Override FPS option to preferences. With it, you override the FPS of the sequences to that value set in the preferences. If not active, FPS is tried to be extracted from the image sequence when possible or from the resolution and aspect ratio when not. Finally, if it all fails, it uses the preferences' FPS setting.
  • Made framesPerSecond attribute in OpenEXRs be read as a string also, to support Nuke saving it as a string instead of a rational number. This setting controls FPS when reading OpenEXRs.
  • Made film.frame_rate and television.frame_rate in DPX files act correctly as a FPS setting.
  • Made television.gamma in DPX act correctly as a gamma setting.
  • Fixed cache line for sequences that did not start at 1.
  • Made FPS 23.976 a default instead of 23.97.

New in mrViewer 3.6.2 (May 7, 2017)

  • Made subtitle always use Arial font by default.
  • Added selection of font for subtitle in the Preferences. Subtitle->Font. It is interactive, you can change it while playing the movie.
  • Made sequence detection more strict by avoiding common movie extensions.

New in mrViewer 3.6.1 (May 2, 2017)

  • Allowed file names like MovieFrame####20.png.
  • In command line, ILM format (not padded) now correctly sets the start and end frame of sequence. So, for example, avatar.61-120.png will set avatar with a start frame of 61 up to 120. Note that padding is not supported in ILM format.
  • Subtitles now work regardless of the location of mrViewer. We change directories before loading a subtitle file.
  • Embedded subtitles are now loaded automatically. No need to call Subtitle->Open for them.

New in mrViewer 3.6.0 (Apr 24, 2017)

  • Allowed image sequences with more than 4 digits in PNGs. Now up to 9 digits are allowed. Previously, files like: MovieFrame00016.png would get rejected.
  • Fixed playback of PNGs due to new code seeking incorrectly.
  • Fixed a crash in Media Information window due to use of an unitialized pointer with PNGs among others.

New in mrViewer 3.5.9 (Apr 18, 2017)

  • Bug fixed File->Open->Single Image. It was not doing what it was supposed to do. Now it loads a single image and the built-in file requester lists sequences as separate images.
  • Bug fixed translation of Open Single Image as Abrir Imagen. Previously it would say Grabar Imagen.
  • Bug fixed yellow line in file requester to always redraw properly and not leave a half line drawn.
  • Made thumbnail picture never exceed 150 pixels in width.
  • Removed a minor memory leak in wandImage.cpp (ImageMagick).

New in mrViewer 3.5.8 (Apr 9, 2017)

  • Bug fixed preload cache of PNGs to do nothing like movie files. This fixes loading of PNGs when they don't begin at frame
  • Bug fixed a crash when a single PNG was attempted to be loaded. It would raise a floating point exception.
  • Bug fixed listing and loading frames with no dots as possible frame spec ( %, d, ) as image sequences. For example, ballred.png. Now the check is more rigorous and they are treated as single images.

New in mrViewer 3.5.7 (Apr 2, 2017)

  • IMPORTANT BUG FIX:
  • Fixes preloading of image sequences, which would crash v3.5.6 due to a debugging abort(). Regression.
  • Added missing ffmpeg utilities to win32 release.
  • Added missing exr utilities to win32/win64 release.

New in mrViewer 3.5.6 (Mar 30, 2017)

  • Made ogg and ogv be valid movie extensions.
  • Improved the FFMPEG PNG reader to allow it to start at any frame in the sequence.
  • Made the FFMPEG PNG reader the default one. This makes reading PNGs about five (5x) times faster or more. It largely depends on multithreading, so machines with several CPUs or cores will see the more benefit.

New in mrViewer 3.5.5 (Mar 26, 2017)

  • Made YUV Conversion preference actually work correctly. Now it sets the color space index upon loading of the movie. You can now still change it afterwards manually in the Media Information Window->Color Space.
  • Changed algorithm to position window when first opened. This keeps window on the Desktop and clips centered. It helps when window would span two monitors.
  • Consolidated not finding and loading of images in sequences. Previously, this could crash the viewer when creating the icons.
  • **IMPORTANT** Moved VR360 channel layer from the channel pulldown as a button in the 3D Stereo Window . This allows putting any layer in 360, not just the color layer.
  • Made caching of sequences independent of VR 360. Previously, VR 360 would get deactivated for caching images.
  • Added a menu and hotkey (ctrl+h) to toggle the hud display.
  • Removed toggle all hud as it is quite useless.
  • Bug fixed LUT turning itself off when switching to VR 360.
  • Made HUD Resolution always display DAW (Data Window) and DYW (Display Window). Previously, when both were equal only a single line -RES (Resolution)- was displayed.
  • Added an environment variable ( USE_FFMPEG_PNG ) to switch PNG reader to that of FFMPEG. The FFMPEG reader is faster and works like a movie file, but it fails when there are gaps in the sequence of frames and it always requires the sequence to start at frame 1.
  • Made HUD display in VR 360 mode.

New in mrViewer 3.5.4 (Mar 20, 2017)

  • Restored sRGBColorspace hint as it was not the cause of double gamma. It is a bug with Windows' photo app.
  • Allowed sequences without first periods, like: image0001.pic instead of image.0001.pic or image_0001.pic
  • Improved window positioning when image is too large. Previously, the borders would be placed outside the desktop.
  • Bug fixed VR 360 which had clipping planes too close to the enclosing sphere and could run into floating point errors ( leading to a cut off sphere ).
  • Added zooming into the VR 360 view with mousewheel or CTRL+ALT+RMB. The zooming is always done on the center of the screen. Not where the mouse is.
  • In VR, 'f' key will reset the view angle to 45 degrees.
  • In VR, 'h' key will center the rotation the view at 0 degrees in X and Y.
  • Added name of maintainer in DEB file.
  • Made postrm and posinst scripts in DEB file be 0755 permissions.

New in mrViewer 3.5.3 (Mar 14, 2017)

  • Using a single instance of mrViewer was not removing the mrViewer.lock.prefs file. Fixed.
  • OpenGL was crashing the program on loading an image when the graphics card was not an NVidia card. Fixed.
  • Removed sRGBColorspace hint from wandImage creator (png, tiffs, etc), as it was leading to two gamma corrections in other programs.

New in mrViewer 3.5.2 (Mar 12, 2017)

  • Fixed a bug of NAN values in the 3dl2ctl.rb converter when 3d lut was a set of values up to 1023 or less. Now the script properly auto detects the depth to use.
  • Added support for 1D luts in cube2ctl.rb. Previously only the 3d lut format was supported.
  • Fixed a crashing bug in audio display when audio was short.
  • Fixed HUD display of resolution when exr had crop areas.
  • Added a View->Hud->All to toggle on/off all hud settings.
  • Made scrubbing be more sensitive to drag. This allows viewing more frames before reseting the scrub with CTRL.
  • Added a new Preference setting: Playback->Defaults->Scrubbing Sensitivity which controls the speed of scrubbing when moving the mouse right and left after SHIFT clicking. The new setting is 4 times more sensitive than what was there before.
  • Reverted back the swizzling of channels on 5.1 or higher as it was leading to very quiet dialogues.
  • Fixed a huge memory leak when working with sequences. Deleting them from the reel was not clearing all memory.
  • Bug fixed requester in media browser asking if image is to be removed when the reel is empty.

New in mrViewer 3.5.1 (Mar 5, 2017)

  • Fixed a memory leak in OpenEXR library.
  • Fixed a memory leak in audio buffer.
  • Made CTL listing list all ctl scripts alphabetically, regardless of what directory they are in. Previously, each directory would list its files alphabetically. Also, repeated CTL scripts are avoided.
  • Added a preference to the Video section to set the YUV Colorspace conversion to something consistant (BT709, Unspecified, BT470BG, etc) instead of reading the information from the movie file.
  • CTL browser now has an Empty button to select an empty CTL (clear it). Previously you had to open the requester to click on an empty area.
  • mrViewer is now friendlier to the pipelines, supporting common LUTs.
  • Added a Ruby command-line script that converts .3dl lut (as created by Nuke) into a LMT CTL script. The script is called 3dl2ctl.rb and is in the bin/ directory of the distribution.
  • Added a Ruby command-line script that converts .cube lut (as created by Flame) into a LMT CTL script. The script is called cube2ctl.rb and is in the bin/ directory of the distribution.

New in mrViewer 3.5.0 (Feb 26, 2017)

  • There was a bug in the theme color selection which would show as random crashes on Windows, particularly when the viewer was in the background. Fixed. If you still see crashes, please report them.
  • Added an option in Preferences to select the number of fstops the LUT will use. This helps to get more accurate values on black levels.
  • On Windows, turning on the LUT automatically was not showing the results immediately. Fixed.

New in mrViewer 3.4.8 (Feb 20, 2017)

  • Added LUT SOP and Saturation nodes to cover ASC_CDL.
  • Added GUI SOP and Saturation to modify the ASC_CDL of ACESclip files.
  • Made GUI SOP and Saturation add 4 look mod transforms if not present: ACEScsc.ACES_to_ACEScg -> LMT.SOPNode -> LMT.SatNode -> ACEScsc.ACEScg_to_ACES
  • Made GUI SOP and Saturation turn on LUT automatically.
  • Made OpenGL use any fixed text if no font of 16 pixels is found.
  • Added HUD display of directory which was missing.
  • Removed libfontconfig.so.1 from Linux distribution as it should use the one installed in the machine OS.
  • Added "Values" button to change values of SOP and Saturation in the Media Information window.
  • Made CTL Preferences not reset the LUT button, but activate it if it is not on and the preference is set to have it on.
  • Bug fixed stereo exr layer selection when images in sequence change the order or count of layer pairs. Note that you cannot expect an image to have layer.rgbaz and the next have layer.rgba and layer.z. Only the rgba will be taken into account in that case.
  • Extracted duration of movies from the movie stream instead of the file context. This leads to better calculation of end frame.

New in mrViewer 3.4.7 (Feb 6, 2017)

  • Made CTL Lut baking calculation faster and more accurate.
  • Made CTL/ICC of monitor trigger a refresh of the view. Previously, the old values were kept until a refresh from other ways happened (switch to new frame, etc).
  • Removed a debugging statement in the seek request.
  • Bug fixed ImageMagick loader to work with different color spaces. This effects log colorspace as found in DPX images. Previously rgb layers would not appear and only VR360 would show up.
  • Added all ACES v1.0.3 CTL transforms.
  • Made CTL browser list all transforms sorted alphabetically.
  • Allowed CTL transform which is only the prefix, like RRT.ctl. Previously those file names would not get shown.
  • Added missing CTL scripts ( LMT.SatNode and LMT.SOPNode ) used to emulate ASC_CDL.
  • Compiled libtiff into ImageMagick which was missing in the previous release on Linux.
  • Removed the auto maximize window on Linux as it was buggy. Now it works like Windows.

  • Fixed chocolatey uninstaller to remove the directory of the mrViewer install.
  • Fixed glsl shaders to compile under NVidia's old drivers.
  • Added FONTCONFIG_PATH to mrViewer.sh to remove warnings of fontconfig. Commented out as, supposedly, unneeded.
  • Fixed LUT crashes due to new stereo engine OpenGL conflicts.
  • Fixed saving of ACESclip XML files only, on Linux.

New in mrViewer 3.4.5 (Feb 3, 2017)

  • Bug fixed GIF duration check, which would result in errors due to ffmpeg new api. Regression from v3.4.1.
  • Bug fixed saving of reels from the gui on Windows. Previously this led to a crash due to libintl conflicting with Windows' stdio.
  • Bug fixed audio device descriptor count as it seems Windows or its drivers impose a limit on the number of open devices. This prevented audio to be played on the 8th clip or so.
  • Made 5.1/7.1 Surround not shuffle channels as they now seem to come ordered from ffmpeg.
  • Added input of , to float input requesters to support Spanish locale on Windows.
  • Added version to chocolatey.

New in mrViewer 3.4.4 (Jan 20, 2017)

  • Bug fixed stuterring NaNs in pixel info bar when loading an OpenEXR sequence. This was particularly buggy on Windows.
  • Fixed documentation, main_toolbar.html, to reflect the changes in stereo.

  • Fixed video frames at the end of movies not being shown.
  • Added Disposition to the video, audio and subtitle tracks' media info.
  • Lowered the severity of errors caused by missing frames. Now they are warnings instead of errors.
  • Bug fixed audio frames on right eye movies at the beginning.
  • Bug fixed a problem with multiple images when not in EDL mode which would lead to stopping and switching to the wrong image.
  • Bug fixed stepping on the second/third/etc. movie in a reel.
  • It is now possible to install mrViewer on Windows using chocolatey. To do so: $ choco uninstall mrviewer -y # in case a previous version is # installed $ choco install mrviewer -y --version 3.4.4

New in mrViewer 3.4.3 (Jan 9, 2017)

  • Bug fixed VR360 on network communication not always opening in the VR360 view.
  • Bug fixed a dead lock of log window due to multiple threads accessing it when in stereo. The problem would show up in Linux, mainly.
  • Bug fixed normalized pixel values when in some stereo mode, like Red/Cyan glasses.
  • Allowed graphics cards with small textures display videos thru scaling down the original video.
  • Bug fixed crash of switching to an empty reel when background image was active.
  • Bug fixed background image being shifted by start frame when not in EDL mode.
  • Bug fixed stereo of Z (depth) channels in stereo OpenEXRs with multipart files. Previously only one channel would be shown or multiple errors would show up if the deepest Z channel was chosen.
  • Fixed a bug where background images would not appear once they were offset in the EDL.
  • Fixed error reporting with frame number to report the actual frame, not one before.
  • Improved synchronism of background images/movies with foreground sequences.
  • Made looping not effect every image in a reel, only the foreground image.
  • Made VR 360 dragging stop after a while. This makes it easier to control.
  • Fixed stepping on background images when they are in the same reel as the foreground image.
  • Fixed compositing of foreground images on background movies due to an overflow in calculations. Now the values are clamped to prevent the error, which showed up on Windows only.

New in mrViewer 3.4.2 (Dec 28, 2016)

  • Added Paint Tools to the Preferences so it can be opened on startup.
  • Bug fixed color area of bottom/top and right/left on stereo output.
  • Bug fixed a wrong memory access due to a race condition on a missing mutex. This bug would often show up as a crash in stereo reels.
  • Fixed a bug that would crash the viewer when selecting stereo viewing and no image was present on the right eye.
  • Allowed fit image to fit the right image only when it is selected in the stereo options window.
  • Allowed gamma control on each stereo image when two sequences or movies are fed. If both images are shown, both images change gamma. If only one image is shown, only that image will change gamma. Note that for stereo OpenEXRs (sxr) or Top/Bottom or Left/Right inputs, both images change gamma always.
  • - Updated log window so it appears as soon as an error is raised (and the Preferences' option is set to such). Previously, the mouse had to be moving or the movie had to be playing.
  • Made normalize pixel values (Norm button) be displayed in pixel bar and in color area, vectorscope and histogram.
  • Added Stereo 3D Options window and Paint Tools Window to those that get hidden on presentation mode (F12 key). Previously it would leave the main window in full screen mode only with OS's toolbars open.
  • Made Stereo Options Window and Paint Tools Window appear/ disappear on network connections.
  • Made Stereo OpenGL active on card capability albeit it has not been tested.
  • Made stereo input and output work in network connections.
  • Bug fixed network connections on different locale (Spanish).
  • Removed language selection from the interface. Now all is controlled with the environment variable LC_ALL.
  • Bug fixed network connections which were severely broken. Now they shouldn't crash and reconnects should be possible.
  • Added VR 360 to network connections.

New in mrViewer 3.4.1 (Dec 21, 2016)

  • Improved the cache saving with stereo sequences.
  • Bug fixed thumbnail creation for sequences with varying data windows.
  • Made stereo 3D cache line in the timeline be bright green. For non stereo caches, the line remains dark green.
  • Bug fixed some movies not showing the last frames of the film on playback.
  • Bug fixed stereo input on images with display windows (OpenEXRs). Now selecting stereo input Top/Bottom will correctly split the image in half to use the top as the left eye and the bottom as the right eye (or viceversa according to stereo output). Using stereo input top/bottom or left/right on images with different data windows will not work well.
  • Made main window appear maximized on startup when showing some large video or image (Linux only). This works very nice in Ubuntu's Unity.
  • Fixed pixel queries on all stereo input/output states. Previously the pixel shown could be wrong or point to undefined memory (leading to potential crashes).
  • Made stereo output changes not clear caches on movies. This removes warnings and errors that would happen otherwise if the movie was in playback.
  • Added Stereo 3D Options Window to preferences, so the window can be shown on starting up mrViewer.
  • Bug fixed color info rectangle to reach the ends of the image when the image has a data window.
  • Bug fixed color info rectangle to work properly on stereo displays (left/right, top/bottom, interlaced, etc). There are still problems with reversed and anaglyphs. Bug fixed a bug when typing a speed of fps which could hang the viewer. The minimum fps is now 6.
  • Added documentation for Stereo 3D Options.

New in mrViewer 3.4.0 (Dec 12, 2016)

  • Bug fixed cache saving for image sequences. Regression from v3.3.9.
  • Made Stereo Window settings be persistent when loading new images.

New in mrViewer 3.3.9 (Dec 12, 2016)

  • Made VR 360 channel appear only once. Previously, when switching resolutions of a multiresolution image, several VR 360 channels would appear.
  • Made int slider in Image Information update on release, instead of on value change. This makes it behave more nicely with mipmaps and ripmaps.
  • Fixed image coordinates when data window is smaller than display window. Previously there would be an offset.
  • Added new 3D Stereo Options panel. This panel allows selecting the input and output options of stereo images. It allows you to show in stereo any group of left/right paired channels in OpenEXRs, instead of just the beauty channels as before. It also allows selecting input of images which have the two stereo channels in them by selecting top-bottom or left-right. This type of movies is typical of youtube. You can also mix this with VR360 for a virtual reality 3D stereo movie.
  • Removed old stereo channels from the channels pulldown. Use the new stereo options window for controlling 3D stereo.
  • Fixed image coordinates and color information on cursor position when in 3D stereo mode.
  • Fixed left and right image sometimes showing up in reverse.
  • Made fit image when changing stereo output.
  • Bug fixed a memory leak when exiting.

New in mrViewer 3.3.8 (Dec 5, 2016)

  • Added VR 360 support for environment maps and VR videos. Images or Videos whose width is twice the height will show a VR 360 channel in the channel pop up and also those with less than 6 channels. When in VR 360° mode, dragging the mouse with the left mouse button (or the middle mouse button) will orient you around and up and down. The resolution supported is the maximum supported by your graphics card ( See About/HW ). On relatively new graphics cards, the maximum resolution is 16384x16384. Note that 3D VR 360 is currently unsupported.
  • Documented VR support in the Main Toolbar section of the html docs.
  • Added a video with the VR 360 workflow
  • Removed an error display in preferences wizard selection when no item is selected.

New in mrViewer 3.3.7 (Nov 20, 2016)

  • Fixed cache line in timeline for sequences which would show only the cache from frame forwardsRegression from v3.3.6
  • Bug fixed a crash in Drag and Drop when several reels were loaded.
  • On Windows fixed the volume indicator which would show only half the volume
  • Bug fixed audio volume control on Linux.
  • Removed empty filename from drag and drop on Linux- Made queue size bigger to handle some movies (Abba_Chiquitita_Español.wmv )

New in mrViewer 3.3.6 (Nov 12, 2016)

  • Bug fixed EDL playback which got broken in v3.3.5.
  • Minimized (fixed?) hangings and crashings due to log window.
  • Made audio track selection in EDL control all clips of EDL.
  • Made Timebar Looping control in EDL control the looping of all clips in EDL.
  • Fixed cache line to not extend beyond the start of clips.

New in mrViewer 3.3.5 (Nov 7, 2016)

  • Made loop mode be an attribute of the movie or sequence loaded instead of the timeline. It is now possible, for example, to have a foreground sequence with loop on and a background movie with swing (ping pong) on.
  • Allowed image sequences to extend beyond their natural image boundaries. The behavior is controlled by the loop mode. If a sequence of 100 frames is played for 200 frames, the end behavior of the sequence will be to stop, loop or ping pong as set accordingly. Note that this feature does not yet work with videos or with sequences with audio attached.
  • Added the -b flag to the command line to load a sequence or a movie in the background of the view window.
  • Made reloading of images work for images in the background of the view window.
  • Bug fixed a problem in ping pong playback of some short movie files.
  • Bug fixed stepping a frame and changing movie files in EDL mode as it would sometimes not revert it to the actual frame needed.
  • Bug fixed playback of some movies with audio in EDL. Previously, some frames would get skipped.
  • Removed a hanging bug which would happen if step frame was set on continuosly while the movie played.
  • Bug fixed saving of sequences with audio as movie files, as the audio would be missing frames. Regression from v3.3.3.

New in mrViewer 3.3.4 (Nov 7, 2016)

  • Bug fixed reloading of images from disk when the creation or modification time changed and the image is not complete. You will get an error when loading the image, but it will get loaded if tried on a second attempt (when it has finished being saved). Previously, the image would not get loaded on a second attempt.

New in mrViewer 3.3.3 (Oct 24, 2016)

  • Bug fixed reloading of images from disk when the creation or modification time changed and the image is not complete. You will get an error when loading the image, but it will get loaded if tried on a second attempt (when it has finished being saved). Previously, the image would not get loaded on a second attempt.

New in mrViewer 3.3.3 (Oct 18, 2016)

  • Audio volume is no longer set at start up unless the value the Preferences->Override Audio is set. This allows you to control the volume from the system's preferences (gnome-control-center, for example)
  • Images (not movies) saved on disk can now be updated and the viewer will refresh the image by itself. You need to check the option in the "Preferences->Loading-> Auto update images when changed on disk"
  • Made exit of playback more solid when there are errors and the error window is up. - ade the error of a missing frame in the sequence be a warning instead.

New in mrViewer 3.3.2 (Sep 29, 2016)

  • Bug fixed file requester closing after typing a filename and choosing a button other than OK or Cancel.
  • Bug fixed file requester not accepting list of images in the form of d. This was a problem introduced in v3.3.1.
  • Bug fixed thread hanging in decode thread when audio was on in a sequence of frames
  • Bug fixed name of movie files saving when in EDL mode. Previously, a number suffix was always added. Now, only when more than a single movie is saved the suffix is added.

New in mrViewer 3.3.1 (Sep 25, 2016)

  • Allowed selection of Favorites, Desktop, My Computer and Documents from the input browser pulldown on Windows.
  • CRITICAL BUG FIX in RE-RELEASE: The first versions of v3.3.1 would not allow saving by typing a new filename in the file requester. The re-release fixes that.

New in mrViewer 3.3.0 (Sep 17, 2016)

  • Bug fixed gif sequence detection. Now mrViewer can load both single animated gifs as well as a sequence of gif files, as those generated by default in Maya's playblast.
  • Added Softimage .pic (si in maya) loader and saver.
  • Bug fixed a crash that could happen when an image was not loaded.

New in mrViewer 3.2.9 (Sep 12, 2016)

  • It is now possible to switch audio device in the Preferences window, Audio section on Windows. For Linux, the preferred way is to leave the setting as default and use the default system audio control (gnome-control-center). By default, the system default audio device is used.
  • In Windows, UNC network paths are now accepted. For example: //gga-desktop1/D/movies/test.mov They can be used from Drag and Drop. Currently, it is not possible to type or pick them in yourself.

New in mrViewer 3.2.8 (Aug 29, 2016)

  • Fixed playback being too fast on 4K video
  • Fixed video stores being kept too long and eating ton of memory. This improves playback of long movies and 4K movies. On Win32 when playing 4K movies, it may be needed to size the cache smaller.
  • Upgraded Windows compiling to MSVC 2015 Community on x64. Win32 uses the MSVC 2012 compiler. This potentially removes Windows NT and XP compatability
  • When mrViewer runs out of memory it will print an error into its message console, instead of crashing.
  • Bug fixed scrubbing on Windows 8.1. It works as a toggle now. You press SHIFT and enter scrub mode. Move the mouse left and right. You press CTRL and exit scrub mode. If you have preferences (.filmaura/mrViewer.prefs) saved, no change in scrubbing is made. If you want the new scrubbing, Untoggle Shift button and leave hotkey1 to LeftShift and hotkey2 to RightShift.

New in mrViewer 3.2.7 (Aug 17, 2016)

  • Updated Histogram in RGB to show colors mixed in areas where R, G and B overlap. So you get R+G=YELLOW, G+B=CYAN, R+B=MAGENTA, R+G+B=WHITE.
  • Bug fixed histogram so R,G,B are averaged with the same maximum value. Previously, each channel was averaged individually, leading to overshooting of histogram.
  • Made audio offset in EDL window shift in opposite direction as it is more intuitive.
  • Audio offset no longer effects other videos in the timeline.

New in mrViewer 3.2.6 (Jul 30, 2016)

  • Audio offset was conflicting with audio loop (clicking on the E in the timeline). This got broken in v3.2.3. Fixed.
  • Bug fixed an audio store problem that would remove needed audio frames. See Matrix_Reloaded_Trailer.mkv.
  • Removed libdl, libpthreads and libX* from Linux distribution as that made them less compatible with current distros. Verified the distribution works in Ubuntu 14.04 and Ubuntu 16.04.

New in mrViewer 3.2.5 (Jul 25, 2016)

  • Bug fix release to address the saving of images with an audio track added.
  • This got broken in v3.2.4

New in mrViewer 3.2.4 (Jul 25, 2016)

  • Added shift audio offset to server-client communication.
  • Added an Override FPS setting to the Save Movie requester to simplify where FPS for saving movies is set
  • Bug fixed audio video sync playback for some movies.
  • This change fixes audio stores, too
  • Bug fixed saving of some movies that would result in mixed frames
  • Made audio offset work in network connections.

New in mrViewer 3.2.3 (Jul 11, 2016)

  • Audio offsets play nicely with EDL now.
  • There's a new audio track below the video track in the EDL Window. It reports the audio offset which can be shifted by RMB+drag on the audio line. This is equivalent to setting the offset from the menus ( Audio->Edit Audio Frame Offset )
  • Avoided a crash in EDL when shifting to a missing frame.
  • Made EDL play correctly when audio offset is different than 0.
  • Shifting (RMB+drag) of clips in EDL now shows the frame being displayed.

New in mrViewer 3.2.2 (Jul 11, 2016)

  • GIFs now return their proper duration, instead of 200 frames.
  • Saving of images with audio added now works again. Audio offset now works without speeding up the image or jumping frames. This bug is a regression from v3.1.0 when it was introduced.
  • Audio offset now works forwards and backwards (negative values)

New in mrViewer 3.2.1 (Jun 17, 2016)

  • Presentation Mode (F12) now covers the taskbar on Linux, just like Windows.
  • Removed idle workaround for Windows as it was not needed. Now the pixel toolbar respects the position of the cursor in playback mode.
  • Bug fixed dummy errors at the end of clips when in EDL mode.
  • Made Log Window show up on Errors on Windows based on user preferences. Previously, it would hang the GUI.

New in mrViewer 3.2.0 (Jun 10, 2016)

  • Thumbnails in file requester are created with the audio off. This makes thumbnails a tad faster.
  • Thumbnails in file requester now select frame in 1/4 of the movie to create the thumbnail. This means thumbnail creation is slower but more representative of the movie.
  • Made fullscreen in presentation mode (F12) cover all the screen space in Windows, instead of leaving 5 pixels visible at the bottom
  • Log Window now displays always the bottom of the log so that it can be read properly on playback.
  • Bug fixed audio playback when changing fps on Linux. Previously, it would change the format of the audio and result in white noise.
  • Bug fixed changing from Native locale to C locale on Linux.
  • Bug fixed volume control on Windows which would sometimes play the audio in mono. Previous fix was incorrect.

New in mrViewer 3.1.9 (Jun 2, 2016)

  • Fixed multithreading issues in file requester when loading icons. It should not crash anymore. Please report any crashes if they show up.
  • Added an option in main UI preferences to select what language the UI works in. Currently, the options are Native (as in Native to the OS) or English. Currently only Spanish and English are fully supported.
  • Updated the English and Spanish documentation
  • Fixed level queries of OpenEXR's mipmaps and ripmaps. Previously the image was not refreshed properly.
  • Made Windows Installer ask if you want to remove a previous version of the software first. This should work with this version on of the program.
  • Made Windows Installer provide a GUI at the end to select which file extensions get associated with mrViewer. The association is with the mrViewer installed last
  • Added libswscale and libavfilter versions to About mrViewer.
  • About mrViewer now reports 32-bits or 64-bits mrViewer (compilation).

New in mrViewer 3.1.8 (May 25, 2016)

  • Removed a buggy fltk::unlock() that could cause inestability in the file requester.
  • Fixed some compilation issues and upgraded all cmake to latest version. This was probably the fix to the audio playing in mono only.
  • Fixed cmake scripts to use WIN64 correctly.
  • Removed debugging message when switching subtitle tracks.
  • Bug fixed surround sound on Windows when 4 channels are in the audio track.
  • Made selecting no subtitle in the file requester not effect on subtitle track display.
  • Cleaned up docs/ directory which was full of unrelated technical documents.
  • Added more Spanish translations.
  • Made file size report in file requester support more than 4GB on Windows.
  • mrViewer on Windows now correctly reports multilingual (utf8) filenames' size
  • Fixed warning of smpteImage not being aligned on 16 bits boundaries for Windows 32 bits.
  • Windows installer will now register most of the file extensions with the latest installed mrViewer. Extensions which belong to editing programs (PSD, etc) are not registered. This is somewhat controversial, so we expect feedback if users don't like the registry entries.
  • Created the web page for mrviewer at mrviewer.sourceforge.net. Also, uploaded the latest manual to the web.

New in mrViewer 3.1.7 (May 18, 2016)

  • Made MPEG4 profiles choose more sensible ones.
  • Fixed typo in ITU 709 being called ITU 702 in Spanish.
  • Bug fixed display of duration and start frame of videos and audios in Media Information Window.
  • Bug fixed duration extraction for video/audio tabs in Media Information Window.
  • Added YUV Hint to the saving of movie files. This setting can be set to control the Color Space in the Media Info Window when the movie is loaded back. The setting controls how the YUV->RGB display conversion is done. For HDTV movies, it is recommended you set the setting to BT709. For others, it is recommended you set the setting to BT470BG (PAL/Secam) or SMPTE170M (NTSC).
  • Added tooltips to all settings in the Save Movie dialog box.
  • Bug fixed a memory leak in subtitles when stopping playback.
  • Added subtitles in different files ( .srt, .sub, .ass ).
  • Bug fixed Windows audio playback playing only in mono. Now stereo and 5:1 is respected.

New in mrViewer 3.1.6 (May 3, 2016)

  • Bug fixed an error in shaders when playing a YCrCb or YByRy movie or sequence. The error would show in debug builds of mrViewer, as an assert failing due to unpremult missing in shader.
  • File requester now opens on the last directory of any drag and drop file.
  • Fixed a rare hanging bug when multiselecting files in the file requester.
  • Shader's YUV display conversion is no longer YCbCr based on resolution but covers the full gamut of Y. The type of YUV display conversion is controlled from the Media Information window, Color Space enum, which in turn can be hinted in the saved movie file. To obtain the previous behavior, set the Color Space to BT709. This addresses the question why movie files created and displayed with mrViewer had a high black pedestal (they were displayed as BT709). Note that this does not currently change the values of pixels in the pixel info toolbar nor in the color area window nor in the file.

New in mrViewer 3.1.5 (Apr 12, 2016)

  • Bug fixed focus (hotkeys not working) when loading and resizing window (a bug introduced in v3.1.4 on Windows mainly).
  • Bug fixed some exif and iptc metadata that was not kept in OpenEXR saver.
  • Bug fixed creation date information on sequences of images
  • Removed a warning about stereo images not being found in an image when stereo came from two image pairs.
  • Bug fixed a NAN display of pixel values when they were 0, due to a bad optimization added in v3.1.4.
  • Made integer entry grow to accomodate values below the 100 range in Media Information window.

New in mrViewer 3.1.4 (Apr 1, 2016)

  • Bug fixed windows preference of child windows (Reel List, etc), appearing at the beginning under the main window. Now they appear above and don't go behind the main window when not selected.
  • Bug fixed network communication crashes due to server running in a different thread than the gfx toolkit. Now the network thread sends signals to the gfx toolkit, instead of trying to apply the change in the same thread.
  • Bug fixed None audio codec in audio saving in Spanish to Ninguno.
  • Made default saver h264, with High profile. - Made conversion to 16 bits from float/half images 10% faster.
  • Bug fixed a display bug in the browser in the media info window when you clicked and "opened" a category.
  • Bug fixed a crash when audio could not be initialized.
  • Localized all audio messages. Added Spanish translation.
  • Bug fixed Connections' Create button in Spanish locale.
  • Bug fixed audio muting when not saving with audio in Spanish locale.
  • Bug fixed memory and disk space reports in media info.
  • Made Reel List save image button save sequences or movie files instead of a single picture.

New in mrViewer 3.1.3 (Mar 18, 2016)

  • Made mousewheel on Windows work when multiple screens are used. This might fix ticket #21 (mousewheel not working).
  • Bug fixed scrollbar in file requester when set to wide view.
  • Added some missing Spanish translations.
  • Removing a reel or removing an image from a reel now present a requester for confirmation.
  • Added support for ProRes movie creation. The movies are created with yuv420p10 color information from 16-bits images. Half and Float images are translated to 16-bits first taking gamma into account and then encoded.
  • Added a profile option to movie saving. This allows selecting the algorithms for compatability with other movie software. Since each codec uses a different name for the algorithm, the h264 versions were used.
  • Added an alert and abort to saving over the same movie you are playing.

New in mrViewer 3.1.2 (Feb 29, 2016)

  • Made file requester leave headroom for icons on images and movies. This avoids the resizing of the scrollbar each time a movie icon is created.

  • Made icon creation in file requester faster.
  • Made the file requester not reset its position as images appear.
  • Made the file requester reset its position on dir change.
  • Made transcoding of movie files much faster and creation of movie files from 8 or 16 bits images, too.

New in mrViewer 3.1.1 (Feb 17, 2016)

  • Relaxed the minimum zoom factor to 1/64 or less. This allows displaying 16K images properly if the card allows it.
  • Transcoding movie files now keeps video and audio metadata, like timecode string.
  • Fixed a crash in EDL editing which would happen when modifying the lengths of the clips.
  • Images bigger than gfx card texture size will print a warning and be drawn as before with a buggy scanline algorithm which does not support gamma or gain changes.

  • Canvas is now set up properly in the PSD saver.
  • Moved to ImageMagick 6.9.3-0 which improves PSD/TIFF saver a tad.
  • Tested under Krita and GIMP and all works well. Photoshop CS 2015 (Trial) shows white areas outside data window when it is smaller than the display window. Not sure why. - Bug fixed channel selection in PSD files. Previously, switching from main Color channel to an R,G, or B channel in another layer, would not update properly.
  • Bug fixed a crash in file requester when icons were being created and user selected the favorites button or changed directories. Now the running icon finishes and then the list of favorites or other directory appears.

New in mrViewer 3.0.8 (Jan 14, 2016)

  • Bug fixed ImageMagick saver to work with PSD multilayer files. It is now possible to take an openexr multi part file and turn it into a Photoshop file. Note that this needs more testing and feedback.
  • Consolidated Favorites paths preferences to be stored under $HOME/.filmaura instead of $HOME/.fltk/filmaura. You should move your favorite list accordingly.
  • Added Memory Display to HUD. It displays physical used memory over total physical memory and virtual used memory over total virtual memory.
  • Fixed a bunch of bugs related to out of bounds memory accesses and undefined variables. This makes viewer less prone to hanging or crashing.
  • Extended 8-bit caching and scaling to stereo caches.
  • Added support to Adobe's DNG format thru the ufraw-batch standalone utility. You need to install it manually in a place mrViewer can reach (somewhere in your PATH). On Linux, this just means downloading it with your packet manager, like: $ sudo apt-get install ufraw-batch
  • Bug fixed audio garbling on Linux once an underrun occurred.
  • Bug fixed cache line to not show images cached past the video length.

New in mrViewer 3.0.7 (Jan 8, 2016)

  • Bug fixed OpenEXR loader loading the wrong channels in animation when image was a multipart image. This could happen if you selected the Color channel and then selected an R, G or B channel from another layer. The image(s) would not get updated.
  • Added OpenEXR preference defaults. These include: number of threads to use when loading files (4 by default), compression algorithm to use when saving files (PIZ by default) and DWA compression value (45 by default) for DWA/DWB compression.
  • Added hotkeys for travelling the channels. By default the next channel hotkey is } and the previous one is {.
  • Improved OpenEXR loader to use less memory on RGB only images and layers. Previously, they were stored in memory as RGBA, with an empty alpha mask. - Bug fixed OpenEXR's multiview images when in stereo mode. Only left stereo was used. This bug was introduced in v3.0.6.
  • Bug fixed the caching of multipart images. Previously, switching from, say, diffuse.diffuse.R to diffuse would trigger the clearing of the cache. Now the cache is kept.

  • Removed black frames when loading a sequence for the first time (before the cache). Bug fixed OpenEXR saver when the source was a movie file.
  • Added all layers saving to image magick saver. This works with TIFFs mostly, albeit somewhat buggy (positions of layers are not kept). PSD should also be supported but when used, it creates all sorts of patterns (albeit layer positions are respected).
  • Removed supposed support for XCF (Gimp) images as ImageMagick does not support it and creates MIFF files instead.

New in mrViewer 3.0.5 (Dec 27, 2015)

  • Made PSD, XCF and TIFF reader read the position and bounding box of layers correctly.
  • Made ICC Profiles not crash on embeded profiles.

  • Made channel selection work with toggles more intuitively
  • Going to N.x with a 'r' hotkey and then pressing 'r' again will bring you back to "N", not "Color" as before
  • Made channel selection smarter to avoid reloads when not needed when using OpenEXR. Only switching full layers or multiparts will cause reloads

  • Added owner of files and directories under Linux only.
  • Made file requester column labels appear translated in Spanish locale.
  • Added a Preload Cache option to both the menus (Image) and the Preferencess->Cache. Turning it on loads the image sequences in the background but it makes the GUI slow. Thus, the default is off.

New in mrViewer 2.9.1 (Aug 21, 2015)

  • Made selection of Favorite follow preferences of a single click to make it consistent with the travelling of folders.

  • Gamma (show pixel values with gamma and gain only)
  • Original (show pixel values unchanged by gain, gamma or lut)
  • Made color area window, histogram and vectorscope react automatically to changes in gamma, gain or lut. This makes all tools more interactive and more useful.

  • Added back again the S and E buttons in the timeline to set the start and ending of clips or the timeline. The E button works well, but the S button is subject to movies' caches when playback in reverse.
  • Use ffmpeg's png loader when cache is off. The loader is really fast but requires opening of the file with the avi (ffmpeg) loader. That means you cannot load the png sequence and then switch to the non-cache loader without reloading the sequence.
  • Simplified drawing routines a tad.
  • Added a warning message about mrViewer's lockfile when the user tries to open a second mrViewer with no images.

New in mrViewer 2.6.6.1 (Nov 20, 2014)

  • Reworked the Preferences->Cache options to allow sequences:
  • Not using any cache for streaming sequences directly from disk. The performance of this is extremely dependent on the images being loaded (in summary, not very good).
  • 8 bit caches to save RAM at the expense of baking the gamma in.
  • Scale to proxy images (one half, one quarter or one eighth of the original size) also to save RAM.

New in mrViewer 2.6.5.6 (Nov 12, 2014)

  • Made caching work on all sequences in reels and timeline in EDL. Progress goes from one sequence to the next.
