Qtutils is a collection of command line programs for manipulating QuickTime videos. It includes, among other things, qtconv, which allows one to change the codec used by a QT file, qtsplit, which splits a QT file into several smaller QT files, and qtsg, which creates a QT slideshow from a series of images and a soundtrack. A script named vcdize also allows you to create VCDs or SVCDs out of QuickTime sources.
