Getting the best results from Sorenson means, well, thinking different. A movie compressed with a data rate of about 10K to 20K per second and a frame size of 240 by 180 pixels might take about a minute to load before playback begins. But the larger frame size and higher image quality may make that wait worthwhile. And if you put text on the page containing the movie, viewers will have something to distract them while the movie loads. Keep the Red Out A strange quirk of Sorenson's underlying compression scheme is that brightly saturated reds compress poorly.
Titles consisting of red text against a black background are likely to look particularly bad.
Consider avoiding bright reds in clips that you'll be compressing with Sorenson. The Key to Keyframes With Cinepak, it's common to specify one keyframe every second. Sorenson doesn't need as many, and gives better results if you specify one keyframe every ten seconds or so. The Sorenson codec that accompanies QuickTime is just a subset of the compression marvels that Sorenson Vision has created. There are additional ways to improve compression and minimize its artifacts.
