XYZ source file to DCP is shifting color
I have a Prores 4444 XQ I'm using as my source file that has properly been converted to XYZ before rendering. When I add my XYZ Prores into DCP-o-matic and set "Colour" to None, color is changing in the DCP when checked against the source. The DCP's color is shifting to yellow/green. Any suggestions on what I'm doing wrong?

Re: XYZ source file to DCP is shifting color
There could be many possible issues with your XYZ conversion - limited vs. full color range, gamma issues, etc. When disabling color conversion, DCP-o-matic takes no responsibility for your source color space conversion and assumes it to be X'Y'Z' (inverse 2.6 gamma) full range at DCI whitepoint.
You are not following a standard procedure when creating your master file.

Re: XYZ source file to DCP is shifting color
Hi,
When you compare the DCP against the source, are you looking at the DCP in the DCP-o-matic player, or some other way?
How did you create the XYZ Prores?
Is it possible to prepare a short sample clip that demonstrates the problem, and send it to me? carl@dcpomatic.com
