yes that would be lovely, but it would require realtime playback to make it worthwhile. No, COLOR isn't a daVinci in that department. And besides, daVinci never detected dissolves or other subtle scene changes --and could generate spurious event boundaries with fast-moving objects or wildly varying contrast.
I agree that it would be great especially since correcting a "baked" show is really a serious compromise to begin with. In this scenario, you're always going to be faced with keyframing transitions, the colour non-linearities associated with that, and likely a drop/non-drop issue if you use "Import as Cut List". See the release notes. Otherwise, hand-cut french fries-- and ALWAYS a better idea to do that in FCP before sending to COLOR. Trust me.
Nope, bringing in the layered sequence from FCP, even if it has been translated via AutoDuck from some other edit package, is the method of choice.
