Even though Avid can’t do what I’m asking for (as least it couldn’t 3 years ago, when iI switched to FCP), their interface approach for what I’d like was perfect. Scenario: you’ve sent a clip to Motion, roundtripped it back, and have it in the FCP timeline. Now you need to change out the shot that was the “base” for the Motion FX. In Avid, when you had filters applied (not talking a “roundtrip” thing here) you could double-click the clip, and it would “open up vertically” to show filters, etc as sort of a layered clip. You could then use regular edit tools to swap shots, etc. SO… if the Motion “returned” clip could somehow be opened in FCP so that the “base” shot could be swapped, without having to export a QT ref from FCP, that would then go into the Motion composite. OR, do you folks overwrite the Motion clip w/ the new shot, send that to Motion, then open up the original Motion file for that spot and copy all the FX content to the new clip?
