I've created some Imovies and find the resolution of the built-in isight camcorder not particularly professional quality. If I shake my head or move quickly - I get a blurred movement. Is there any way to adjust the resolution so its better quality? "Analyze for stabilization after import" seems to make no quality improvement (IMHO). I'm running 21.5 inch IMAC OS X Version 10.6.2 3.0 GHz Intel Core 2 Duo processor, 4GB 1067 MHz RAM and the Imovie is 9.0 version 8.0.5 (820)...
