New in Aegisub 3.0.0 (Oct 3, 2012)

  • The audio display and related things such as the karaoke syllable splitting interface have been rewritten from scratch. The spectograph rendering is now much higher quality and faster, and many new features have been added.
  • Changes made in the main edit box and surrounding controls no longer have to be committed. Instead, changes are made to the file as you type, with the video display updating in real time.
  • General:
  • Many things are much faster.
  • The main toolbar can be hidden.
  • The clipboard is not cleared on exit.
  • The mouse wheel scrolls the thing the mouse is over rather than the thing with keyboard focus.
  • Dragging and dropping audio or video files onto Aegisub no longer blocks the source of the drag while they're loading.
  • Added Euskara (Basque) translation.
  • Remove files from the MRU lists when they no longer exist (#717).
  • All of the toolbar icons have been replaced with new ones.
  • Audio:
  • The audio display has been rewritten from scratch. As such, many minor details have changed.
  • The spectrum mode is higher quality and much faster.
  • The waveform mode shows the average value of the audio at each time in addition to the maximum. This can be disabled if it annoys you.
  • By default, left-click-drag sets the start of the line to clicked point and the end of the line to the dragged point, making it possible to time a line in a single click.
  • All selected lines are shown on the audio display.
  • The previous and next line can be shown in the audio display (in addition to previous or all) (#664) (#1386).
  • Adjacent pairs of lines with equal end/start times can be adjusted together similar to karaoke syllables by holding down Ctrl (#20).
  • Nonsensical line and karaoke syllable timings are no longer allowed.
  • The audio display jumps around less when the zoom is adjusted (#957).
  • The zoom/volume are saved across sessions.
  • Middle-click jumps the video to the clicked time.
  • 24-bit and float audio are supported (#1292) (#1490).
  • Added an option to automatically load audio when opening video (#1134).
  • Added Shift-G to advance to next line and reset timing to default even if the next line is already timed (#946).
  • Spectrum mode is now the default (#943).
  • Spectrum mode now uses logarithmic scaling rather than linear, which usually better exposes speech (#944).
  • Enable the dummy audio provider in release builds (#1425).
  • Karaoke:
  • The Karaoke split/join bar is hidden when not in Karaoke mode (#987).
  • Keyframe markers can be disabled in karaoke mode without disabling them for dialogue timing (#644).
  • Splitting and joining karaoke syllables preserves override tags and comments (#1190).
  • The karaoke split/join interface has been redesigned to require fewer clicks. Click in a place with no splits to add a split, or on a split to remove it.
  • The sum of the syllable durations must now equal the line duration.
  • Adjusting the syllable before the active syllable while the syllable is playing no longer extends playback (#886).
  • Automation:
  • Removed Ruby and Perl automation engines since no one used them and they didn't work.
  • Removed auto3 since it's been deprecated for years and auto4 is much better.
  • Macros can now be hotkeyed. The command name for macros is "automation/lua/file-name-sans-extension/macro-name" (#517).
  • Added a few more stock macros (#120).
  • The clean tags macro no longer breaks \clip (#1450).
  • The automation manager dialog is modeless.
  • Multiple scripts can be loaded at once with the Add button in the manager dialog.
  • Lines appended to the end of the file are automatically put in the appropriate section.
  • Scripts do not have to be UTF-8 (but generally should be anyway). As a result, adding a BOM is now generally required if a file must be treated as UTF-8.
  • Macros which do not run to completion (either due to the user cancelling or an error occurring) do not make any changes to the file, so it is no longer necessary for complex scripts to build up a table of changes which are then applied in one shot.
  • An undo point is now automatically set at the end of the macro if the macro fails to do so, or makes changes after the last undo point.
  • The standard Lua module system is now supported.
  • The active line argument to the macro processing function actually exists now.
  • The macro processing function can now set the active line by returning a second value containing the row index to make active. The new active line must be one of the lines which the selection is being set to, or it will be ignored (#1435).
  • The validation function can now modify the help text displayed for the macro by returning a second value containing the new help text (#1413).
  • A third function can now be passed to register_macro. This function receives the same arguments as the validation function, and if it returns true a check mark is displayed next to the macro in the automation menu. This is probably not very useful yet.
  • Added several new functions to the aegisub global table.
  • Added bindings for the standard platform open/save file pickers.
  • Added clipboard module for accessing the system clipboard.
  • Added re module which exposes wxRegex's regular expression functionality, which is significantly more powerful than that built into Lua.
  • Fonts Collector:
  • The fonts collector handles bold and italic (#659).
  • The fonts collector actually works rather than just copying a giant pile of possibly related fonts (#660).
  • Fonts with non-English names are collected (#1061).
  • Add the current subtitle's directory as a destination (#1059).
  • There is a warning if a font used does not contain all of the glyphs needed.
  • There is a warning if the user tries to use more fonts than will work on playback.
  • The dialog is modeless.
  • On platforms where symlinks don't require admin privileges, fonts can be symlinked rather than copied.
  • Fonts used by styles which are used by no lines are no longer copied (#660).
  • Hotkeys:
  • Hotkey support has been completely rewritten. Many more things can be hotkeyed.
  • Customized hotkeys are not automatically migrated to the new format and must be recustomized.
  • Hotkey assignment is now more flexible: any command can be assigned to any context rather than a limited subset of commands having global versions. For example, rather than having "Audio Play" and "Global Audio Play" commands, there is a single audio play command which is simply bound to different hotkeys for when the audio display has focus and when anything else has focus.
  • Preferences:
  • The preferences system and everything has been rewritten from scratch. A bunch of stuff works better now as a result.
  • Preferences from 2.1.x are not automatically migrated to the new system. No one ever got around to writing the migration. Sorry.
  • Shift Times:
  • Double-clicking a history entry loads the settings from that entry (#1427).
  • The dialog is now modeless.
  • Saving history works with unicode usernames (#1269).
  • Spell Checker:
  • All words can be added to the user dictionary, rather than just words which fit in the language's character set.
  • Commented lines can be automatically skipped (#1428).
  • Re-add hyphen to the word separator list since removing it caused more problems than it solved (#1459).
  • Subtitle Formats:
  • Saving subtitles as a non-Unicode character set which does not have all of the characters used in the subtitles now replaced bad characters with ? rather than failing silently (#837).
  • Added support for more non-Unicode character sets (#639) (#666) (#849) (#877).
  • Fix rounding errors when generating SMPTE timecodes.
  • Add support for EBU STL unformatted level 1 teletext.
  • SRT files with only formatting supported by SRT can be saved directly rather than having to be exported.
  • Fix several issues with SRT reading and writing.
  • Improve handling of invalid ASS files.
  • Add menu entry to open subtitles from the currently open video (#253).
  • Improve performance when opening subtitles from Matroska.
  • Fix loading of subtitles from Matroska files greater than 2 GB.
  • Subtitle Rendering:
  • The Windows 32-bit builds now ship with three subtitle renderers: MPC-HC VSFilter (default), xy-VSfilter and libass. 64-bit builds include MPC-HC VSFilter and libass. Non-windows builds include libass only.
  • Fix some crashes on malformed files in VSFilter (#1485).
  • Style Manager/Editor:
  • The style manager dialog (but not the style editor) is modeless.
  • Renaming an unused style doesn't prompt to update the uses of it.
  • Do a better job of selecting the right thing after styles are created, edited or deleted.
  • Fixed some memory leaks in the style editor.
  • Style names are now case-insensitive to match VSFilter (#777).
  • Subtitles Edit Box:
  • Changes no longer need to be committed; anything done in the edit box is applied instantly.
  • Undo no longer does insane things when combined with changes made from the edit box (#586).
  • Undo no longer reverts changes to the filename from Save As (#1345).
  • The syntax highlighter better reflects how the line will actually be parsed for malformed lines.
  • Splitting lines leaves the old line selected rather than moving to the new one.
  • The color picker updates the color of the line immediately rather than waiting for the dialog to be closed.
  • Subtitles Grid:
  • Much of the selection-related logic has been improved and made more consistent.
  • Fixed the "clicking near top/bottom of grid selects multiple lines" issue yet again (maybe for real this time) (#1041).
  • "Make time continuous" uses the next/previous line if only one line is selected (#822).
  • Concatenated lines are joined with spaces rather than \N.
  • Concatenating out-of-order lines sets the start and end time correctly.
  • Recombine Lines can be used on any number of lines at once rather than just pairs of lines to join.
  • Recombine Lines now handles more cases correctly (#1468).
  • Subtitle lines can be sorted by several fields rather than just the start time, and either all lines or only the selection can be sorted (#1457).
  • Noncontiguous groups of lines can be duplicated.
  • The scroll position and current line are restored when reopening a file, similar to the current video frame position (#1417).
  • Shift-scrollwheel scrolls the grid a page at a time (#1407).
  • Alt-Up/Alt-Down move all selected rows rather than just the active one.
  • Timing Post-Processor:
  • Lead-in is applied before lead-out, so that it is used if there is not space for both.
  • Overlaps can be automatically removed when not adding lead-in/out.
  • Keyframe snapping is in milliseconds like everything else (#548).
  • Translation Assistant:
  • Now modeless, making it much easier to watch relevant portions of the video.
  • Enable spellchecking and syntax highlighting in the edit box.
  • Video:
  • Seeking no longer blocks the UI while video decodes, making seeking multiple frames (especially backwards) far faster and more responsive.
  • Video zoom levels are no longer constrained to a limited range.
  • Setting the zoom via hotkeys or the dropdown with detached video works (#493).
  • The script resolution is automatically set to the resolution of the first video opened. Alternatively, a default script resolution can be set.
  • Prompting when the script resolution does not match the video resolution is once again enabled by default (#1138).
  • The display aspect ratio is set automatically when opening anamorphic video.
  • Support for loading timecodes and keyframes from Matroska when using the Avisynth video provider has been removed, as it was horribly broken (#939) (#1049).
  • Seeking the video while it's playing works.
  • Fewer things cause video playback to stop.
  • Default to decoding all videos as if they were BT.601 rather than their actual colorspace to match VSFilter's rendering.
  • Write the colorspace used to the subtitle file so that the above hack can go away sometime in the future.
  • Enable multithreaded video decoding via FFMS2 as it now actually works.
  • Add support for VP8, VC-1 and interlaced H264.
  • Fix some more OpenGL issues with bad drivers.
  • Fix some rounding errors in the VFR logic.
  • If there are multiple audio/video tracks FFMS2 asks which to use rather than only supporting the first (#905).
  • Visual typesetting tools:
  • Multiple drag handles can be selected at once to move multiple lines at once, or to shift multiple control points of a clip mask. Ctrl-click adds or removes a handle to the selection; clicking on no handles clears the selection.
  • Holding Alt while double-clicking on the video in the Cross mode sets all selected lines rather than just the active line (#513).
  • Holding shift makes all visual tools apply only the greater of the X or Y change (#993).
  • Double-clicking in drag mode does the same thing as in the Cross mode.
  • The visual typesetting tools can be hidden when the mouse is not over the video, to make it easier to see small subtitles.
  • The visual tools are now always the same size regardless of zoom level (#966).
  • The subtools are in the main visual tool toolbar rather than their own mostly empty one (#1401).
  • The tools support subpixel precision.
  • Visual tools can be hotkeyed (#992).
  • Add support for the scale parameter of vector clips (#1415).

New in Aegisub 2.1.9 (Feb 7, 2012)

  • Audio: Might be a little faster when displaying keyframe markers (pink lines)
  • Audio: No more "You pressed cancel!" pseudo-errors when canceling audio loading
  • Automation: Fix for rare furigana layout issue in karaskel
  • Automation: The append operation for the subtitle object now intelligently appends dialogue lines to the end of the Events section instead of absolute end of file, solving issues with appending dialogue after attachments
  • Automation: Returning selections from Lua macros now works correctly, no longer shifts the selection down by one from the intended
  • Automation: The table.copy_deep function in utils.lua now works as advertised and handles self-referencing tables and circular references
  • Automation: Added new "remember/recall" suite of functions to Karaoke Templater
  • File i/o: Selecting charset/text encoding after opening a non-Unicode file now properly respects your choice
  • File i/o: Added support for writing the EBU STL (tech 3264) subtitle data exchange format
  • File i/o: Warn if trying to load a binary .sub file, which is likely a VobSub file (which is not supported)
  • General: Changed compilation settings to make the Windows binaries smaller without sacrificing speed or functionality
  • General: VSFilter is now linked as a normal DLL dependency instead of dynamically discovered at runtime, using alternative CSRI renderers no longer possible, this should make loading a wrong vsfilter almost impossible
  • General: Various input methods on Linux should work more reliably now
  • General: Fixed a variety of memory leaks
  • Help system: The locally installed help would never actually get used when using Help buttons or the Help menu
  • Hotkeys: Fixed a bug where having a hotkeyable item having no hotkey would cause wrong key combinations (try to) activate that anyway

  • Style Manager: Duplicating a style and renaming the copy no longer gives a rename warning
  • Style Manager: Fixes to copying styles between storage and script
  • Style Manager: All controls are now dynamically resized, as a result it is overall a little larger and adjusts size to fit translated texts
  • Subtitle grid: The subtitle grid now also takes the width of column title texts into account when calculating column sizes, allowing translations more freedom in choice of column texts
  • Subtitle grid: Fixed the "clicking near top/bottom of grid selects multiple lines" issue, and other row selection issues
  • Timing post-processor: The "make adjacent" threshold now has the end of the range be inclusive
  • Translation Assistant: Fixed a control layout issue on Mac, preventing it from working properly there
  • Translations: Added Polish
  • Translations: Added Farsi (Persian)

New in Aegisub 2.1.8 (Jan 30, 2010)

  • Overview
  • Official Mac, Linux and Unix versions. The Mac version is still alpha quality, though, and we don't have specific binary packages for many Linux distributions.
  • Fixed the "Could not lock buffer for filling" problem when playing audio on Windows 7, and rarely on Vista too.
  • The video display is now much more compatible with limited OpenGL drivers and should work on all systems, notably Windows Vista and 7 with standard drivers.
  • Clicking "Play" on the video now only plays audio if you have explicitly opened audio from the Audio menu. If you want to hear any sound you now must load audio via the Audio menu.
  • The Portable version is now (almost) full-featured, only missing is ASSDraw3, because making a portable version of that is non-trivial. We also have an upgrade installer saving you a lot of download, if you already have 2.1.7 installed.
  • Details
  • Fixed a bug with the Kanji Timer feature, where clicking some buttons before setting everything up could cause a crash. (#977)
  • The Transform Framerate export filter didn't work correctly at all. (#1014)
  • All common occurrences of "Could not lock buffer for filling" on Windows should be fixed. (#1028)
  • Fixed a possible crash with an uncommon sequence of actions in the colour picker. (#1025)
  • The Detached Video is moved into view on opening now, if it was partially or entirely outside the desktop area. (#1040)
  • The version checking function was completely rewritten to work on all platforms and be more flexible. (#1071, #365, #970, #1080)
  • The "play audio from video" function was removed, the Play buttons for video now only play audio if audio has been loaded. This is done because we can't support the playback reliably otherwise. (#1090)
  • Handle malformed SSA/ASS files missing the [Script Info] line. (#440)
  • Several strings that should be translatable weren't. (#791, #792)
  • Fixed a glitch in the new DirectSound audio player, causing strange behaviour if dragging the selection start during playback. (#915)
  • Split (by karaoke) sometimes created lines that couldn't be properly joined back by Join (as karaoke) later. (#929)
  • If holding the Shift key while dragging audio selection start/end markers, sometimes the time edit boxes did not get updated (#942)
  • Prevent making the audio selection have negative start or end times. (#942)
  • The "relayer" function in Karaoke Templater did not work. (#950)
  • Fixed a visual glitch with spell-checker suggestions in the subs edit right-click menu. (#971)
  • The Hour field in the Jump to dialogue box was not filled in correctly when the box opened. (#1003)
  • Added support for the undocumented \fs+ and \fs- tags to various transformation functions. We recommend avoiding these tags as they may not be supported in all renderers. (#1007)
  • Rewrite the file type associations code and interface on Windows, to conform better to the guidelines and overall integrate better with the Windows shell. (#1037)
  • Add support for the \iclip tag to the "Clean Tags" Automation script. (#1044)
  • The Windows installation program now confirms that existing shortcuts point to an Aegisub version being upgraded before overwriting them. (#1046)
  • Automatically set the video zoom level on video load, so the video never takes up too much space in the window. (#1054)
  • Fixed the subs edit not being able to use all fonts on Windows. (#1072)
  • Fixed a crash in the style manager when copying a style from storage to subtitle file, and the subtitle file already had a style by the name. (#1096)
  • Automation 4 Lua truncated the "spacing" field to an integer on read back, instead of keeping it as a float as it should. (#1019)
  • Rewrite parts of the video display to better handle OpenGL drivers with reduced features, notably the Direct3D-based implementation by default shipped with Windows Vista and Windows 7. (#1020)
  • The Windows installer will offer to remove an existing Mesa3D OPENGL.DLL file in the Aegisub install directory, as it's generally no longer needed for reliable video. (#1057)
  • The Windows installer now installs VSFilter as csri\VSFilter-aegisub.dll to avoid possible clashes with VSFilter.dll files in other locations. Any existing csri\VSFilter.dll is removed.
  • General improvements to robustness of the Windows installer.
  • If upgrading from 2.1.6 or earlier, an existing Aegisub.exe will now be renamed to aegisub32.exe during installation, to help Windows update existing shortcuts later.
  • If the offline manual isn't installed, clicking a Help button will open the online manual instead.
  • On Mac, added an option in the Help menu to open a folder with example files and other goodies. (#1033)
  • The Mac version uses wxWidgets 2.9 instead of 2.8.10, which overall gives much better stability and UI experience.
  • Update to a newer FFmpegSource2 version that fixes many video-related bugs. (#1017, #1030, #1048)
  • Many fixes to the Unix build system. (#831, #989, #1064, #1074, #998)
  • Added an OSSv3/OSSv4 audio player for Unix systems. (#1089)
  • On Mac, show a message while FontConfig is building or rebuilding its index of fonts on the system, for subtitle preview. (#841)
  • Fix a crash issue, if trying to add a word to a dictionary where the word contains characters that can't be represented in the encoding the dictionary file is stored in. (#999)
  • Fixed several bugs in the colour picker, causing the screen dropper tool to only work on Windows. It now also works on X11 and Mac. (#748)
  • Fix minor graphical glitch with the main tool bar flickering when changing line. (#1117)

New in Aegisub 2.1.7 (Jul 14, 2009)

  • It's been almost a month since the 4 year anniversary and the promise of 2.1.7 "within a few days", but lots of stuff happened, people were travelling and otherwise not reachable. But I dare say it's not a bad thing, this version of Aegisub we are releasing now is certainly more polished than what we could have managed four weeks ago.
  • So far, this release is just for Windows. Use the Download button above to get the new version. Release notes and more on what to expect after the break.
  • A lot of things have changed since version 2.1.6, and sure, it has also been a long time: More than half a year! Here's a summary of the more important changes.
  • DirectSound audio player has been completely rewritten (again) - this should give much better stability of audio playback. Note that the old DirectSound player is still available, you can change to it in Options. If you're using Windows 7, the old one seems to be more reliable.
  • PCM WAV audio provider actually works again, and with files of any size. (No more crashing with files bigger than 256 MB.)
  • Tip of the Day has been removed.
  • Loads of changes to FFmpegSource2 (FFMS2) giving better support for almost everything, making it more stable and so on.
  • Lots of memory leaks have been fixed, Aegisub should use less memory now.
  • Bug fixes in many file format readers and writers. Loading and saving subtitles to foreign formats should be more reliable now. Problems with frame-based/SMPTE timecode-based formats fixed.
  • The Kanji Timer function has been almost completely rewritten, squashing all known bugs and giving a prettier GUI. The use is the same.
  • OpenGL errors in the video display are no longer fatal. You will get an error message, and video won't open if Aegisub doesn't support your graphics card/driver, but it shouldn't crash. See below for a workaround if video doesn't work for you.
  • Some additions to Karaoke Templater, you can now create loops with variable iteration counts (including infinite!) making a lot of effects more feasible.
  • The "Local configuration" option was removed from Options. If you want a "portable" version of Aegisub (as it was intended for making) we now have a separate download package for that. It also actually works as advertised now. See the download page for details.
  • An innumerable amount of other minor, cosmetic changes that just makes everyday use more convenient and smoother.

New in Aegisub 2.1.6 Release Preview 2494 (Nov 26, 2008)

  • Apparently the fix on 2.1.5 caused audio selection to become much slower. This release will hopefully fix all of those issues. Since this is a very minor change, you can download a RAR with only the new executable (plus its pdb) and extract it over the 2.1.5 install (typically "C:Program FilesAegisub").

New in Aegisub 2.1.5 Release Preview 2481 (Nov 23, 2008)

  • Fixed a bug in audio display that caused it not to update properly (introduced on 2.1.4)
  • Fixed a bug that caused Aegisub to crash if you attempted to load any ASS subtitles with malformed embedded fonts
  • Tweaked the layout of the visual typesetting bar

New in Aegisub 2.1.4 Release Preview 2455 (Nov 14, 2008)

  • Hopefully removed the dependency on Visual C++ 2005 SP1 runtimes
  • Greatly improved the draw speed of audio display (should make committing on spectrum mode much faster, depending on your settings) - please let me know if any instabilities are caused by this
  • Fixed the aspect ratio of video when the audio display is too tall
  • Added Hungarian translation
  • Fixed a styling glitch in the fonts collector and translation assistant
  • Made Aegisub capable of running if ffms2.dll isn't found
