You COULD to this, but first off, you need the xml converter tool.

Second I wouldn't trust it. When FCPX first came out, I was really excited about this feature and about FCP finally being color managed.

I took some slr clips, took them into a timeline and did a background transcode of all my clips. Then I compared the transcode version and the original, and low and behold, the same compressor gamma shift I had always seen in this scenario.

Color managed my.....

Took the same clips into AME or AE or PP even, and the before and after h.264 to prores 422 look exactly the same. I've always had bad gamma shift issues with h.264 to prores and the x did nothing new in this area.

Perhaps xdcam to prores would behave better, but again, it's something to look out for.
