I have rendered a comp using the provided GoPro Cineform codec, at FilmScan1 quality, using the workspace color profile (Adobe RGB 1999), using 16bpc in my project. When I import the file into After Effects, it looks wrong - the gamma is off, and the colors are washed out. If I go to Interpret Fottage -> Main -> Color Management, it says the embedded profile is Rec 709, and I can't change it because all the options are disabled. I have provided a screenshot below. What can I do?
What version (to the decimal) of AE are you using?
