FCP inherent (unwanted) level & gamma changes – unlike Avid’s AMA

Someone noticed that XDCAM-EX footage imported to FCP appeared different as compared to Avid (AMA import).  Addressed in an Avid forum thread started May 2010, referring to FCP 6.06 and Avid 4.02: http://community.avid.com/forums/p/84153/473798.aspx

  • What AMA gives is, is _exactly_ what the camera has captured. What FCP shows you, is a remapped image, most often with a gamma shift. 
    • (For Avid AMA imports, Avid settings for RGB or 601 etc. make no difference – it’s always as-recorded).
    • … imports (to FCP) will look different (to expected), because FCP/QT “corrects” the gamma when bringing in footage (even if you would not want that).
  • Most people seem to agree that FCP works in 0-235, not 0-255, not 16-235. And without the option to leave things untouched. So if you import something into FCP, there’s no getting it back to the original levels anymore.

I guess I’d better do some experiments with ramps & scopes etc…
