started out as a college project, and has since grown. Wax is good for both
home users and professionals. It can be used as a stand-alone application, or
as a plug-in to other video editors. The software also features unlimited video and audio tracks with top-down compositing

very technical. It is full featured, offering many different effects. It can
edit up to 256 video, audio, and still image clips. There are up to 64 effects, which can be chained serially.

Online video editing programs

jumpcut.com – Jumpcut is a web based video editing software and now it’s even part of the Yahoo! family. You upload video or small clips just like importing inside desktop software.
