An impressive open source package mainly supports AVI files
Pros & Cons:
VirtualDub is an impressive open source package that is regularly updated by its author. Note that it mainly supports AVI files and can read (not write) MPEG-1 and BMP images but doesn't handle some video formats like DVD or MP4. And like all video software, it needs a pretty fast PC.
In the world of video editing VirtualDub has always been there. It's a very reliable program that with the right amount of knowledge can accomplish just about any task.
VirtualDub is licensed under the GNU General Public License , meaning you can use it for free. No risk involved, and the whole source code is available if you want it.
The package is however not complete without the additional filters. A comprehensive collection of third party filters is available from here.
