Thanks, david, I’ll try that.
I got a good response on another forum, too:
From Kevin Brock
“For output, I would spit out a reference movie. PS seems to open them fine. That way there is no extra compression going out. So, in FCP, go to File > Export > Quicktime Movie. In the resulting pop-up window, make sure “Make Movie Self-Contained” is not checked. Now you have a reference to your original media without transcoding and taking a quality hit. PS should open this movie up fine – does for me, using a ProRes HQ reference movie.
Then, coming back out of PS, I’d just use the setting that matches the destination sequence in FCP. ”
