Simple Video Splicer (SVS) is a basic video editing tool for
cropping/joining movies, images, and audio. Since iMovie 3 will finally be
able to do everything that SVS can do, I’ve decided to make the project
source code openly available.

SVS and it’s source can be found at (http://www.chipersoft.com/svs.html)
