Im editing a rather large project (over 4 hrs of video) and I imported the footage through iMovie so that it would split up the video into separate clips from the DV start and stop time. when I import the footage into FCE and play it in the Viewer it appears very very choppy and usually it freezes the video but i can still hear the audio playing. THen, FCE becomes unstable and crashes. I am using my Powermac. When I import directly into FCE I dont seem to have this problem.
