Please let us know if the above fixed it for you.
It seems to me that the problem is in the software and how it references the video material in the scratch drive. You said that edits had been rolled. As if your “ins and outs” have been shifted. I’ve seen this before with HDV timelines being exported via FCP’s Batch export to H.264. I haven’t been able to find an explanation for it, but I speculate that it has to do with HDV’s long GOP structure and FCP finding the wrong frames within that GOP to export.
If any one can please shed some light on this subject it would be handy and I think I’ll create a fresh post regarding the issue that I’ve experienced.
