Does the DCP-o-matic CLI take into account colour space?

Post by kristophm »

I used Dcp-o-matic CLI to render a DCP and my master video file is in Rec.709 colour space (Gamma 2.4). Does the CLI automatically identify the colour space and transform to XYZ accordingly? I did not see an input flag for colour space in the CLI documentation.

If the answer is NO, is there a way to set the colour space in the CLI somehow?

I ask also because the colours appear slightly muted when I export an mp4 test video file from the DCP using ffmpeg.

Thank you.

The CLI will guess the same as the GUI does when you first add a file - if you need to change settings in the GUI after adding your file we will need to add an option to dcpomatic2_create to make the same change.
