  • Filters: Rescaling after changes to filter chain now extends or trims ending ranges as needed to match changes to frame count.

  • Filters: Filter preview no longer always runs the filter chain with the input video mode set to default.
  • Display: Added workaround for video card/driver combos that perform extremely poorly with DirectDraw/Direct3D blits overlapping a secondary monitor. This can be toggled in Options > Preferences > Display.

  • Filters: Fixed incorrect frame being sampled after edits were done on the timeline.
  • UI: Removed "run as job" check box from Save Image Sequence dialog, since it's now redundant with the "queue batch operation" command.

New in VirtualDub 1.9.5 Build 32593 (Aug 24, 2009)

  • Additional YCbCr format support. v210 and NV12 are now supported by the blitter engine and can be selected as input and output formats. The internally supported 4:4:4 planar "YV24" mode is now exposed as well.
  • Display improvements: The Direct3D 9 display minidriver has been updated to render several more formats in hardware, including HDYC, v210, and Pal8. In addition, on devices supporting pixel shader 2.0 or above, it can dither higher precision data down to 8-bit, most noticeable with the 10-bit/channel v210 format.
  • Multi-frame fetching in video filters: The video filter system has been rewritten to support a request/process model. The result is that video filters can now explicitly request multiple source frames for each output frame they produce. This eliminates the need to do tricky internal buffering inside of a video filter to emulate such support and makes it much easier to implement video filters that require a frame window, such as field shifters and deinterlacers.
  • New video filters: You can now switch field dominance with field delay, change frame rate with linear blending with interpolate, and merge fields into interlaced frames with interlace. The warp sharp filter is now internal, with added YCbCr support. IVTC is now a video filter instead of a special-cased pipeline stage, so it can be repositioned within the filter chain and its output can now be previewed on the timeline.
  • Video filter updates: Levels, brightness/contrast, field swap, and convert format have improved YCbCr support. The deinterlace filter now supports more powerful ELA and Yadif modes.
  • Video filter 3D acceleration: The video filter system now supports 3D hardware acceleration through Direct3D 9 for filters that support it, which can give speed improvements with a fast video card and a long chain of 3D accelerated filters. This is still in its infancy, but expect improvements in performance here in the future.
  • Video filter API improvements: Additions to the API to aid video filter authors include support for aligned scanlines for SSE2 support, and the ability to tell the smart rendering system when a filter can be bypassed.
  • Configurable keyboard shortcuts: Keyboard shortcuts for all menu commands in edit mode are now customizable, letting users set up more efficient workflows.
  • Additional internal decoders: The internal MJPEG decoder can now be used in 64-bit builds, and the internal Huffyuv decoder is also useful when no 64-bit decoder for Huffyuv is available.
  • Performance improvements: The audio render buffer size can now be tuned. Also, the rendering status dialog now shows you more pertinent stats on the buffer levels of the audio and video pipelines and the activity levels of the I/O and processing threads, giving better visibility into bottlenecks.

New in VirtualDub 1.9.4 Build 32559 Experimental (Jul 28, 2009)

  • [bugs fixed]
  • Fixed chroma subsampling and 4:1:0 chroma positioning in test videos
  • Scene stepping works with panes disabled.
  • Fixed crash in scene stepping with certain frame sizes and 24-bit RGB selected as the input format.

  • Filters: Fixed cut off size text in cropping dialog.
  • Filters: Field bob, threshold, and sharpen filters were added to the list even if the configuration dialog was cancelled.
  • Capture: Devices that don't declare a frame rate now cause an error rather than a crash.
  • [regressions fixed]
  • Fixed compatibility problems with Windows NT 4.0.

New in VirtualDub 1.9.3 Build 32507 Experimental (Jul 6, 2009)

  • Go To Prev/Next Drop command now works after the timeline has been edited.
  • Fixed random frame codes on the one-after frame.
  • AVI: fccHandler header value for newly generated uncompressed videos with non-RGB formats is now set to the FOURCC to work around encoders that don't accept DIB.
  • AVI: Fixed bug where zero-byte pad frames were lost if the video stream had a non-zero dwSampleSize value set.
  • Filters: Cropping button is now grayed out for disabled filters, since the input size is unknown.
  • Filters: Fill filter now shows correct input size when there are earlier filters (although, currently, the image is still incorrect).
  • Filters: Fixed bug where crop bounds weren't recorded correctly if the up/down buttons were clicked and a thousands separator appeared.
  • Filters: Fixed random crash in interlace filter when switching formats.
  • Filters: The manual field order options in the IVTC filter were flipped.
  • Filters: Resize no longer forces a conversion to YV24 when resizing YV16 input in interlaced mode.
  • Display: Fixed crash in GDI minidriver when displaying interlaced video with a 0x0 pane.
  • DV: Fall back to subsequent frames if the first frame has invalid audio metadata.
  • Capture: Fixed preview window being the wrong size when filtering/cropping is enabled and preview acceleration is off.
  • Capture: Fixed inconsistency in capture timing defaults. This only matters if you haven't already run VirtualDub in capture mode once.
  • Capture: The AVI superindex/subindex settings now also apply to captures.
  • regressions fixed
  • Filters: Fixed error in IVTC computations for RGB32, YUY2, and UYVY formats (since 1.9.1).

New in VirtualDub 1.9.2 Build 31953 Experimental (May 8, 2009)

  • 1.9.2 is now out as a new experimental release. This version mainly solidifies the changes to the filter system made in 1.9.1, with reworked allocators to further reduce memory usage and caching improvements for better performance.
  • Several users have asked me why the "run as job" option was moved from the save dialogs to submenu options in 1.9.x. The reason why I removed it is that I was getting a lot of reports of people unable to write any files with VirtualDub, which turned out to be due to unintentionally leaving that flag on. Unfortunately, this made those batch commands a bit more annoying to get to. 1.9.1 added a keyboard shortcut for batching "save as AVI" as a stopgap. 1.9.2 now allows reconfiguration of all keyboard shortcuts for commands on the menu, which allows all of the remaining batch commands to be accessed quickly. This turned out to be easier to implement than I had expected, with the exceptions being that (a) storing the shortcuts in both a forward and backward compatible way was tricky, and (b) I had to write my own hot key control as the Win32 one has some silly hardcoded restrictions on what keys can be accepted.

New in VirtualDub 1.9.0 Build 30586 Experimental (Dec 22, 2008)

  • 1.9.0 is of course the new experimental build and contains a number of new features and changes. I spent some time closing the gap in functionality between the x86 and AMD64 builds, so although the AMD64 build may still not be as well optimized, several features that were previously absent in the AMD64 build are now implemented. I've also thrown in a built-in AMD64-capable Huffyuv decoder that handles some of the popular post-2.1.1 extensions. Second, the internal display and blitter libraries got overhauled quite a bit. The uberblit system that backs the resampler in the 1.8.x series has been cleaned up and expanded, and now handles many of the complex blit scenarios that were previously handled by custom code or multi-stage blits. As a result, VirtualDub 1.9.0 can now handle several new image formats, including the 10-bit per channel v210 format and the interleaved NV12 format. The display library has also been upgraded to handle the new formats, and in particular the Direct3D module can now accelerate display of 10 bit/channel v210 video with dithering. The new formats are not yet exposed to video filters -- mainly because the thought of trying to work directly in v210 scares me -- although I'm not ruling out the possibility of a 14-bit fixed point linear color format in the future.
