I thought this post was going to be about Macromedia Flash movies from the subject... The only thing I can think of is maybe your hard drive is severely fragmented? Was the transition finished rendering? Were there any other applications open? Here are some suggestions: - Quit all other applications - make sure iMovie is done rendering everything before playing back - if it still stutters, try exporting to a DV stream and re-importing to iMovie -- this will make sure the video file is as contiguous as possible. Hope that helps? - Mark > Despite my hardest endeavors I am still struggling with iMovie 3.0.2 ! > Transitions that I play on the timeline 'flash' as the timeline curser > passes into them i.e. where the clip ends and the transition starts.
