My question is would you really want to use a program, the entire UI of which is geared towards photography, to do sophisticated color editing of motion imagery?
As a huge volume of still photographers have migrated to some extent to video, it's probably a great time to have a program that mimics the interfaces they are accustom to.
Apple's color is ok, not great, not really bad, (I would NOT call is sophisticated, but requires a whole different learning curve that few still photographers and their assistants will take the time to master.
RED has a good interface for base corrections and since it is proprietary to their systems, works well.
My point is more times than not, we shoot some video with a still session and obviously we want to get as close to the same look as possible from the video to the stills, at least in first view in web galleries.
When I go outside for grading, I make stills of the video, work them in photoshop, print and take those to the colorists to match. It saves thousands of dollars in time for the colorists to know from the start where we are going.
For video finish, there are outside systems a whole lot more robust and in 12 bit that work much better than Apple's color.
We do a great deal of video correction in CS5 and 6 as we are use to the interface.
Anyway this isn't a deal maker or breaker for me, but if phase wants to gain market share over adobe, this would be a way to do it, though as we know Phase will do what they want.
Always have.
IMO
