Avoiding Gamma Shifts Between FCP & AE?
What are some of the best ways to take video captured in FCP, effect it in AE, then back to FCP while maintaining the same gamma levels? Also, can you maintain the super-white information when round-tripping? I do understand the differences between YCbCr and RGB color spaces.
FCP 6.0.6
AE CS3
QT 7.6.2
Mac OS 10.5.8

Oh, I just want the super-whites because it gives me more to play with. They don’t go out for broadcast that way!
I’ve read that Adobe article before, but it hasn’t really helped me (my brain may just be mush). the legacy Quicktime option doesn’t make it any better. The gamma on the AE-rendered video still won’t match the gamma of the FCP video, as shown on my WFM. I’ve done round-trip tests with the Black/White ramp generator in FCP, and can never get them to match up without applying a Curves filter in AE to compensate.

I’ve gotten swamped and haven’t been able to do what I need to do to get to the bottom of this, but I started my render tests over (since I can’t remember exactly what methods I did a couple months ago). Codecs involved are DV25, DVCPRO50, ProRes D1, 8/10-bit Uncompressed D1. I’ll report back soon with additional information and results.

Removing the legacy AJA uncompressed codec, that is.
