Hi Chris,

Sorry I couldn’t have helped sooner but I saw your post when trying to solve the exact same problem. I’ll post my solution now, for posterity.

In the Sequence Settings, under Video Processing, choose Always Render in RGB. It seems that rendering ProRes video in YUV can be problematic. I haven’t read up on this yet, though. Changing to RGB solved this issue for me.

Note that you must make this change on every effected sequence.

Best,
Jake

Hi Chris,

Sorry to hear you’re having trouble. Because I was under deadline, I gave up on trying to troubleshoot the problem, and just went in and manually repaired the managed timeline. This was no small task, but was eventually successful. I found, for the most part, that clips weren’t actually missing, they were just 1-frame in duration, or so. Since I was working in a 40-minute or so long timeline, I couldn’t tell this without zooming way in. In general, I think I just had to extend all the clips back to their usual lengths.

Good luck!
Jake
