Colour space

Dear DCP-o-matic Team,

I noticed that importing a Pro Res 4444 tagged as P3 D65, DCP-o-matic seems to read it as colorspace REC709 (s. attachent). Since I am setting a P3 colour conversion, do you see a problem? Or should I go for the REC709 setting instead?
Thank you!

ProRes native colorspace is rec.709. While it may be flagged internally in the file as P3 correctly, DCP-o-matic's underlying FFMPEG framework may not detect this properly - hence the content properties you see. You should also see colors being far off in the DCP (whites/greens) if you let it use the wrong colorspace. So, set it to P3 manually. It is not a good idea to use non-standard video formats/properties.
