Wide Gamut HDR color processing

One of three Color Processing settings (in the Project Properties Inspector) in Motion. Choose Wide Gamut HDR for projects that contain only HDR media or that you intend to export in the HDR color space. Choosing this setting sets the working color space (the color space that’s used for all processing operations) to linear RGB with Rec. 2020 color primaries, a color space with a wider range of colors than Rec. 709.

The other two Color Processing settings in Motion are Automatic and Standard Gamut SDR.
