is a video capture and video processing utility written by Avery Lee.

It is designed to process linear video streams, including filtering and recompression, but lacks features common to dedicated video editing software. VirtualDub was originally created for the purpose of compressing anime videos . Released under the terms of the GNU General Public License,VirtualDub is free software.


VirtualDub operates on AVI files, requiring that appropriate video and audio codec are installed.

Video capture and creation

VirtualDub has digital and analog capture capabilities. It supports both DirectShow & Video for Windows capture.

Capture features include capture to any AVI variant, audio VU meters, overlay and preview modes, histogram, selectable crop area, video noise reduction, auto stop settings (based on capture time, file size, free space, and/or dropped frames), and designate alternate drive(s) for capture overflow.
VirtualDub can also help overcome a common problem with digital cameras that also record video. Many models, especially Canon, record in an M-JPEG format that is virtually incompatible with some NLE programs, such as Vegas 6.0 and 7.0 simply saving such an AVI file as an old-style AVI in File allows the video to appear in Vegas.

VirtualDub supports DV capture from Type 2 (VfW) FireWire controllers only .
There is no DV batch capture, still image capture, or DV device control capability.

VirtualDub can also be used to create a video file from a series of bitmaps or targa.
This requires that individual frames are given file names numbered in sequential order without any gaps (e.g. 001.bmp, 002.bmp, 003.bmp...). From those, the frame rate can be adjusted, and other modifications such as the addition of a sound track can be made.


VirtualDub can be used to delete segments of a video file, append new segments, or reorder existing segments. However, segments of different files cannot be mixed, and no transition effects can be applied.

VirtualDub comes with a number of filter. Examples include reducing the video size by half, converting the video to grayscale, arbitrary rotation and about a dozen more. Plugin filters further extend VirtualDub's capabilities. A filter SDK is available for developers to create their own video and audio filters.

In addition to applying filters, entire image sequences can be saved to hard disk as BMP or TGA files, which may be later modified. In addition, the sound track can be extracted from a video, and modifications made to it; filters can be applied before the track is spliced back in. Frame sequences and sound tracks must be edited in external software programs.
