I don't know if anyone posted already, but when Apple Color loop bug is so stubborn sometimes and Clipfinder's fix does not even work, I found out some facts that might cause this issue and figured out how to over come this issue.
- You shoot with pre-build 30 camera and the proxies are generated by the camera.
- Then edit using the proxies in FCP with the latest color science. In FCP timeline there's no indication of problems like the screen turn green.
- Send the timeline to Color, then you would have some clips especially, with single R3D file (short clips that only takes one R3D file) that work fine. Then you would have some clips that are stuck and won't play. You can normally fix this issue with our familiar Clipfinder Color loop bug fix, but under some situations like footage are from pre-build 30, then you are editing with FLUT color science with all of the latest REDLINE and all, then some footage won't get fixed even with the Clipfinder.
I found that some problems happen wether you used the edge code or TOD during editing. The timecode choice inconsistency could result in this? I don't know, but if you find that you have some clips don't get fixed with loop bug, try to switch the timecode choice other way around. You can do this with Clipfinder's edit loupe function.
Then next important thing to do is that when you change the timecode (thus affects the RSX setting which won't do anything for FCP and Color), you must regenerate the proxies to take this in effect. Also you might have to reconnect the proxies on the FCP timeline after you rengenerate the proxies. This is so, because FCP figures things out like timecode from the proxies (for proxy editing). Then you would have to send the reconnected timeline to Color, go through normal Clipfinder loop bug fix and there you go.
To regenerate the proxies, please be warned that with the latest RED software, Clipfinder has problem generating proxies in bulk nor single proxies. I use old RED software with Clipfinder in another computer to be able to regenerate in bulk.
