VirtualDub provides users with free and comprehensive video capture, processing, and linear editing suite.

With VirtualDub, users can capture video from a variety of sources, including DirectShow and Video for Windows capture. The software allows for fractional framerates, improved disk usage, real-time noise reduction, and capturing to any variant of AVI, among many other features. The software works with DV capture over FireWire.

Users may also perform high-performance linear operations on video files, such as audio track replacement, decompression, resizing with bicubic and bilinear resampling tools, and application of many video filters that can adjust the video image, sharpen or blur, smooth, deinterlace, and more.

VirtualDub also allows for adjustment of frame rate, removal of specific segments of videos, and more, all with live previews complete with audio. Each operation can also be batch-processed on many files at once.
