Hi all.
This list has been quiet for a while...
Quick question: DCP-o-matic applies gamma correction when making a DCP
from a ProRes. When using "Export" to convert a DCP back to ProRes, does
DOM apply gamma correction in opposite direction? If so, to what? 2.4 or
2.2?

Hi Jim,
This surprised me a bit, but FFmpeg is doing this gamma correction (I
think). It seems that it will gamma correct to sRGB's 2.2-equivalent
gamma. Does that fit with your observations?
This should probably be fixed to use 2.4, or (better) be optional.
Best regards,
Carl
