Standard Gamut SDR color processing
One of three Color Processing settings (in the Project Properties Inspector) in Motion. Choose Standard Gamut SDR for projects that contain SDR media or that you intend to export in the SDR 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. 709 color primaries.
The other two Color Processing settings in Motion are Automatic and Wide Gamut HDR.
