Sequence drifts out of sync after Color
I’m currently onlining and color grading a feature. Source files are 1920×1080 23.98fps uncompressed captured via a Kona LHe. I took the project into color, did the grading, and am exporting as ProRes 1920×1080. When I play the new rendered sequence back in FCP (using a guide track that worked fine with the uncolored source clips), it falls out of sync and gets progressively worse. The soundtrack gets ahead of the picture. I have verified that the soundtrack, source clips, and new rendered media are all 23.98fps. I tried re-rending the clips in Color using the uncompressed codec, and it yielded the same results. So, the new media is the same spec as the rendered files, but the rendered clips fall progressively out of sync (whereas the original clips in the FCP sequence did not have a sync issue).
I’m not sure it is related, but I am also getting a “xxx cannot be rendered in a sequence of this size with the current graphics card,” where xxx = “The effect color solid” or “The effect light rays” et al. I have the film divided up into six reels each under 20 min.
My specs:
Brand new Mac Pro Octo-Core 2.8 GHz
8GB RAM
Stock ATI HD 2600 XT (as far as I can tell, this is the most recommended card for this sys)
System drive = 320GB Sata
Media drive = internal 3 x SATA RAID (RAID 0) – suitable for ProRes certainly

Andrew,
You might want to try your handles settings in Color – I had a few funky clips when I rendered sequences with handles, especially if there were any clips that had no handle media – for instance motion MOVs. It didn’t screw the timeline (i.e clips started in the right place) but the sync within some clips was odd, and there were a few shortened clips too. Nothing that couldn’t be fixed with some slipping and sliding but was a PITA.

I ran into this sync problem as well. I’m not 100% sure of this, but I noticed in the project that I’m working on that the clips that were not linked to their audio when I sent them to color do not drift out of sync.
Meanwhile, the clips that were linked to their audio were fine.
