DCP files color range incorrect


(Nimesh Shrestha) #1

Looks like the DCP or DCI 2K Jpeg 2000 fiels generated from MTI Cortex Ent has color range problem. When it is played back on DCP playback softwares(easyDCP or CineAsset Player with XYZ to Rec.709 conversion, it gives unusual color.When color conversion is set to “none”, it is giving the right color, it’s weird.Somebody from MTI should mention the proper way to create DCI 2K Jpeg2000 files.

What color space did you choose in Cortex when creating the DCP?

Hi Peter,
Thanks for the response. I chose Jpeg2000 DCI 2K with XYZ 12 bit in Deliverables and Input source as Rec 709 in DCP Settings. The source footage was ProRes 422 HQ.[/uploads/default/original/1X/9cac364d99021fd11734647abe8dcc52aaaecce7.JPG][/uploads/default/original/1X/2bf40607b8732b1712b8a4687f13aea98f092068.JPG]

The top one is with XYZ to RGB conversion applied in the DCP player(CineAsset Player), as well as other players.
The bottom one is with the color conversion not applied.

Hi Peter,

This is a cropped snapshot of what is showed on a desktop DCP player when XYZ to RGB color conversion applied.Normally when color conversion is applied it should show the actual color.

This is the image with the actual color.
