I’ve seen this on just one of my projects, which was initially done by another editor in FCP7. We needed most of the timeline integrated into a new piece so I decided to bring it over to FCPX.
I opened the old project, exported XML, translated with SendToX, and imported. It’s a 23.98 timeline and many of the clips (including stills) have this sub-frame issue. Because of the tight turnaround, I didn’t have time to troubleshoot. The issue manifests itself seemingly randomly with about 30% of edits. Ended up simply overlapping with connected clips to cover the half/quarter/eighth/sixteenth frames.
I was able to fix a couple of instances just now by selecting a problem clip and modifying the timing – selected 100% speed, then Automatic Speed (this locked it into correct full frame timing). When I tried it on another clip from the same shoot and camera, the Automatic Speed setting changed the clip speed to 250%! It’s a talking head on green screen, shot at 23.98.
I’ve only experienced the problem on this particular project, and have a little time to poke at it, so will see if there are more clues.
