VirtualDub - программа для захвата и обработки видеофайлов. Она умеет читать и писать AVI2 (OpenDML) и многосегментные AVI-файлы (для преодоления барьера 2 Гб). Имеет встроенные декодеры MPEG-1 и Motion-JPEG, а также позволяет подключать иные видео- и аудио-кодеки. Программа поддерживает создание AVI с дробной частотой кадров, удаление и замену звуковых дорожек, импорт звука из внешнего источника, удаление любых фрагментов из видеоряда и склейку видеофайлов. В VirtualDub имеется мощный набор фильтров, таких как blur, sharpen, emboss, smooth, 3x3 convolution, flip, resize rotate, brightness/contrast, levels, deinterlace и threshold. Такой набор неплох даже для графического редактора. Кроме этого, имеется возможность написания и подключения своих собственных фильтров.

Build 33815 (1.9.X, experimental): [July 14, 2010]

[features added]
* Holding the Ctrl key during drag-and-drop appends instead of replaces.
* "Scan for errors" command is now scriptable (VirtualDub.video.ScanForErrors).
* Save Animated GIF command is now scriptable (VirtualDub.video.SaveAnimatedGIF).
* Added ability to import and export raw video.
* Added ability to export through command-line encoders.
* Added support for 0-255 paletted grayscale.
* Added support for Rec. 709 and full range formats.
* Added command to copy source and output frame numbers to the clipboard.
* Render: Added option to show the status window for batch operations.
* Render: Video compressor threading is now allowed for two or more threads when operating with only key frames.
* Filters: Added multithreading support.
* Filters: Added "gamma correct" filter.
* Filters: Added "alias format" filter.
* Filters: Re-added deblurring mode to IVTC filter and added preview support.
* Filters: Added frame drop mode to IVTC filter.
* Images: TGA RLE compression can now be disabled.
* Images: Added support for PNG alpha channel.
* Capture: Multiple capture devices with the same name now appear with a distinguishing counter.
* AVI: The non-zero start warning can now be disabled in preferences.
* AVI: The number of filename counter digits used when saving segment sequences is now configurable.

[bugs fixed]
* AVI: The preferred handler (fccHandler) field in the video stream is now ignored by default for consistency (unless re-enabled in preferences).
* UI: Limit minimum window size to avoid caption redraw artifacts.
* UI: Fixed bug where aspect ratio of panes in unconstrained aspect mode would drift when auto-sizing was enabled.
* UI: Select Range command is now disabled when no video is loaded.
* UI: Audio conversion dialog no longer occasionally says "No change (8-bit)" for compressed formats; this was sometimes incorrect as when that option was selected the pipeline actually used what the codec produced, which was usually 16-bit.
* UI: Video codec dialog now scrolls the list on open to always show the last selected codec.
* JobControl: Auto-shutdown now works over remote desktop and records a planned shutdown on server versions of Windows.
* Images: PNG images with 16-bit/channel grayscale now load properly.
* Images: Fixed GIF autodetect code checking the footer instead of the header.
* Hex editor: Fixed icon in RIFF tree window.
* Filters: Switched the frame that the IVTC filter drops in reduce frame rate mode to match the old pre-filter algorithm.
