Hey guys, I've got a screencast I took using Snapz Pro, and it's saved as a .mov file on my desktop. It looks great, and is about 8 MB. When I import it into iMovie, however, every second or so there's a "twitch" in the video, where graphical anomalies appear around the edges of things, then settle away again. This happens with all .mov files I've tried. So, is there any way to stop this from happening with a minimal loss of quality? I scoured the net and it seems this is just a general issue with iMovie importing video files, but I figured if anyone knew of a fix, I'd find it here.
