I've just edited a video in iMovie, (OS 9.2.2), exported it to Quicktime, and been very disappointed with the result. When I watch it in iMovie the quality is excellent, but the resulting Quicktime movie is complete rubbish; it makes your eyes go funny. In my Applications folder was an earlier version of Quicktime, much to my surprise, which I've now trashed. In my Applications (OS 9) folder is version Z1-5.0.2. The playback is still rough as rats, but could the older version (Z-4.1.3) have prevented the newer from performing correctly when iMovie was exporting the film to Quicktime?
