VirtualDub is one of the most popular video processing software in the world. Its powerful video editing and processing capability is obvious to all. It has a built-in filter plug-in with rich functions, which works with the XviD or DivX codec, and is widely used in video editing, compression processing, image adjustment, caption compression, DVDRIP production and many other aspects. The biggest highlight of this big version update is that the audio part of the existing video can be directly replaced by the audio track of other videos or the most common MP3 audio (it is absolutely fun to invite several friends to match a movie with a personalized voice dialogue). In addition, its video capture function can now easily capture the screen and mouse pointer (similar to the screen recorder function) And coding compression. Small size, powerful, completely free, such software is hard to find!
