Exact same thing happened to me yesterday – mid project. Attached is what the same file looks like in FCP & in quicktime. This goes way beyond the ‘Enable Final Cut Studio color compatibility’ issue in quicktime. I have reset my Pram- Deleted my FCP pref files. No luck. i exported an xml to Premiere & the files look great. I then opened the same project file on a different mac and everything looks fine – no CRAZY gamma color shift. A can’t seem to find a resolution! I tried switching System Settings/Playback control/Gamma Correction from Accurate to Approximate (in FCP) but it still does not look right – Why would this happen mid project!?
