VirtualDub is a video capture/processing utility for 32-bit Windows platforms (95/98/ME/NT4/ Win2k / Windows 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.

What's New:

Native AMD64 build (see Release Notes for restrictions).
New "perspective" video filter can deproject subimages that are displayed obliquely in a scene.
YUV formats can now be directly selected for decompression and compression.
Planar YUV formats are now supported for both display and output.
Added preliminary DirectX 9 (D3D9) display driver support, with support for filter mode selection and multipass bicubic filtering. This driver must be manually enabled in Preferences.
Added OpenGL display driver, with support for filter mode selection. This driver must be manually enabled in Preferences.
Frame seeking is now incremental so that extremely long frame distances between key frames no longer hang the app during the preload.
Added support for the PRELOAD flag on video decompression to speed up seeking.
New position slider that displays frame number markers and supports mouse wheel scrolling beyond 32K.
Fast recompress format is reported in log.
Basic movement keyboard shortcuts now work in filter preview.
JPEG image sequence input and output is now supported.
Single images can be opened as video files.
Integrated DV video decoder.
Audio is now decoded from type-1 DV files.
Audio filter dialog now has a position control to allow previewing at arbitrary points.
The frame indicator in the timeline control can now be customized via Preferences/Timeline.
