If I want to send a film to a festival what should my project settings be in my NLE when dealing with color grading 1080p 14-bit cinemaDNG footage in After effects? i.e. If I have understood this the working space I must select is P3 DCI gamma 2.6 and depth at 32bpc? Or do I keep my working space to rec 709 gamma 2.4?
I have openDCP or DCP-o-matric at my disposal for the DCP conversion. Since I cannot directly export to DCP in AE what is the best intermediate format to export to resulting in no quality loss?
