VirtualDub is a video capture/processing utility for 32-bit Windows platforms (95/98/ME/NT4/2000/XP), licensed under the GNU General Public License (GPL).
It lacks the editing power of a general-purpose editor such as Adobe Premiere, but is streamlined for fast linear operations over video.
It has batch-processing capabilities for processing large numbers of files and can be extended with third-party video filters.
VirtualDub is mainly geared toward processing AVI files, although it can read (not write) MPEG-1 and also handle sets of BMP images.

* Added distributed job queue mode.
* Added bob and non-interlaced field display modes to render preview.
* Added new test video mode: interlaced cube.
* Added option to run video compressor in a separate thread for better dual core/SMP performance.
* YCbCr resampler is now SSE4.1 optimized.
* Added command-line switches for minimizing/maximizing the window on startup and setting process priority.
* AMD64: The threshold, grayscale, levels, logo, and brightness/contrast video filters are now available.
* Plugins: Fixed bugs with and raised size limits for serialized input
* plugin options data.
* [bugs fixed]
* Fixed cases where the crop/letterbox to aspect ratio options in the resize filter were broken.
* Fixed another rare crash when exiting filter list dialog.
* Fixed Postpone and Delete buttons in job control dialog sometimes not updating when a job state changes.
* Fixed swapping of AVI superindex and subindex settings.
* Fixed bugs with cropping in filter chain with YUY2 or UYVY formats.
* Mouse wheel scrolling with Shift held down (by key frame) now works properly.
* Fixed infinite loop when attempting to convert a pal8 source to 4:2:0 YCbCr.
* The initial load of AVI files is now faster over a network.
* TARGA files are no longer written all black when 32-bit RGB output is used.
* Added workaround for "image not in Y or YCbCr format" errors when reading JPEGs from a RAZR V3 phone.
* Deleting a filter in the filter list no longer causes the checkboxes to desync from the actual filter enable states.
* AVI: Files with truncated hierarchical AVI indices no longer result in "missing 'movi' chunk" errors and can now be recovered.
* DV: Fixed decoding issue that resulted in some lost blocks.
* DDraw: Fixed occasional crash when another application forces full-screen mode.
* Capture: Fixed crash in OpenGL screen capture mode related to occlusion query based frame dropping.
* Capture: Fixed hang on shutdown when exiting with OpenGL screen capture mode active.
* [regressions fixed]
* Fixed crash when a script specifies arguments for a video filter that doesn't take any.
* Data rate was reported incorrectly for the video stream in the status dialog.
* Fixed audio display.
* Fixed crashes and decompression errors with paletted video.
* Filter preview no longer shows bogus frames when previewing a filter chain
* with edits on the timeline and no frame rate changing filters.
* Filters: Codec-friendly alignment works in resize filter again.
WHAT'S NEW IN VERSION 1.7.7.28312 Stable / 1.6.19 Stable:
* Improved accuracy of "set so audio and video durations match" for short clips
* Fixed vertical chroma positioning errors when converting to 4:2:0 or 4:1:0 YCbCr
* PluginSDK: Direct stream copy from a plugin audio stream caused dwStreamSize in the AVI to be set incorrectly
* PluginSDK: Fixed crash when using plugin to load a file with an audio stream that isn't AVI compatible
* Capture: When "wait for OK" was enabled with a DirectShow driver, time spent in the dialog was counted against a time stop condition
* Capture: Fixed crash when an error occurs while starting capture with a custom hotkey
* "Save segmented AVI" no longer crashes when only video is enabled
* Prohibit zero for frame rate adjustment
* Filters: The error return from runProc is ignored again for compatibility with earlier versions of VirtualDub; this fixes some video filters that broke in the 1.7.x series
* D3D: Fixed a display change related crash
WHAT'S NEW IN VERSION 1.7.5.28225 Stable / 1.6.1:
* Audio display couldn't be opened if the curve editor was open
* Temporal smoother filter crashed in out of memory conditions
* Fixed rare cases where WAV reader returned the wrong data
* Capture: Fixed crash in screen capture driver with video cards that only support OpenGL 1.0
* Capture: Screen capture driver sometimes drew garbage cursor before first cursor change
* PluginAPI: Default I/P frame model wasn't working
WHAT'S NEW IN VERSION 1.7.4.28204 Stable / 1.6.1:
* Fixed bug where frame regions were shifted instead of extended to fix key frame violations in direct video mode
* If a video filter errored out during start phase, already initialized filters didn't receive end calls
* Toggling the "show decompressed video" setting in Fast/Normal Recompress modes could result in a crash
WHAT'S NEW IN VERSION 1.7.2.27700:
* [features added]
* Added minor frame lines to the parameter curve editor.
* Input driver plugin support.
* The threshold, sharpen, and brightness/contrast filters now support preview.
* The DV type-1 audio source can now be set to conceal errors.
* Rendering operations can be throttled or paused.
* Capture: Screencap driver can now capture the mouse cursor.
*
* [bugs fixed]
* AVI parser now handles files with a significant amount of garbage prior to the first video or audio chunk.
* Curve editor opens to current frame instead of frame 0.
* Smart rendering didn't check the right locations in filter opacity curves if edits had been applied.
* Animated GIF decoder didn't handle the "erase" and "restore" disposal modes correctly.
* Animated GIF decoder could display a one-frame glitch at start of decoding.
* Time-based filters and filter curves weren't reflected in output preview when applied to a repeating frame.
* Fixed interlaced field DirectDraw display with planar YCbCr formats.
* The "smart rendering" option could cause a missing codec error even if the video mode was set to Direct.
* Added workaround for BlackMagic MJPEG codec not producing key frames.
* Added workaround for update problems with the Direct3D and OpenGL display modes in Windows Vista.
* Capture: Fixed crash when attempting to use "remove duplicate frames" feature of screencap driver on a 3D card that didn't support occlusion query.
* Capture: Fixed crash in screencap driver on 3D cards that don't support buffer objects.
* Capture: Fixed bugs in screencap driver's rescale function.
*
* [regressions fixed]
* Fixed inaccurate length field in WAV header.
* D3D: Fixed memory leak.
* AMD64: MPEG video decoder now works.
WHAT'S NEW IN VERSION 1.6.16 Stable:
* Added AMD64 versions of the frameserver and AVIFile frameclient.
* Added .divx to file filter for video open dialog (although AVI files should be tagged .avi, dammit).
* Fixed decoding errors when reading JPEGs with junk at the end of the file.
* Improved support for working with video codecs that are configured to only output YUV formats.
* Added more checks to script parameters for "resize" video filter.
* Fixed gradient bugs in "smoother" video filter.
* Added "png" file extension to logo filter open dialog; it has been supported for a while, but you had to manually override the file filter.
* Fixed truncation in audio displacement setting that prevented it from working beyond ~35min.
* Capture: Fixed crash when attempting to capture with both striping and segmentation (not supported).
* Capture: Audio playback sometimes didn't work.
* Capture: Fixed noise issue in resampler.
* Improved accuracy of "box blur" filter.
