Alexander, I have used iShowU and it does some weird things for recording video to be edited. It doesn’t record a constant frame rate. So it may be playing anywhere from 5 to 30 FPS. I use the DV50 Codec which seems to work well. I haven’t used the animation codec but DV50 exports close to the same size as the original.
