Hi Jason,
Just wondering if you ever worked out the route cause of this problem. We are basically experiencing excatly the same issues, according to your screen shot.
The footage was shot super 16, telecined to digibeta, captured 10-bit uncompressed via a blackmagic extreme card, edit in FCP 5, Automatic ‘Duck’ed to AE 6.5. Footage is fine in 8-bit, but has the fine green/red lines when in 16 bit. BTW this is regular live action, not green screen footage.
We haven’t made any system alterations during the project.
If you’ve got any ideas i’d love to hear ’em!
Thanks – Jim
