We are using FCP5 and have been experiencing the same issue with the gamma. By now I am sure you figured a work around, I wanted to post in the event someone else gets affected by this same issue.

We believed that the issue stems from Photo Jpeg not being 100% dedicated to RGB. FCP has issues with the gamma, even if Quicktime does not.

The fix may require some extra rendering in the beginning but i have found it does fix the problem and you can go on with your editing as normal.

Simply export your original file in Quicktime to a Planar RGB. This forces the video to full RGB. You can export it back to Photo JPEG after and you should no longer experience the gamma shifts.

A lot of render time but if you have a file that needs fixing at least you can, without going insane.

By the way if you don’t see the Planar RGB codec option, goto ‘Quicktime Preferences” then advanced and check off “Show Legacy Encoders”

Hope this helps =D
