When using the RED presets, I notice Premiere CS5.5 is using MPEG-2 I-Frame compression for the sequence (when I do an Export > Match Sequence Settings).
How would I setup After Effects to match the same compress as the sequence?
I'm guessing: Profile 4:2:2 / Level High. GOP M=1 N=1 Closed=0.
Why are you using Match Sequence Settings from Premiere Pro? In most circumstances, that's not what you want.
Likewise, why do you want to do this from AE?
