working color space
The color space that’s used for all processing operations (such as color correcting, blending, retiming, and so on) while working in Motion. You can choose between three different color processing options (in the Project Properties Inspector). The color processing option you choose sets your project’s working color space:
Standard Gamut SDR: Sets the working color space to linear RGB with Rec. 709 color primaries. Rec. 709 is the current standard for HDTV projects, including HD cable, Blu-ray discs, and streaming video.
Wide Gamut HDR: Sets the working color space to linear RGB with Rec. 2020 color primaries, a color space with a wider range of colors than Rec. 709. Rec. 2020 is useful for 4K and 8K UHDTV and HDR projects.
Automatic: Sets the working color space based on the current Render Color Space setting (in the View pull-down menu). If the Render Color Space setting is Rec. 709, the working color space is set to linear RGB with Rec. 709 color primaries. If the Render Color Space is set to Rec. 2020, HDR Rec. 2020 HLG, or HDR Rec. 2020 PQ, the working color space is set to linear RGB with Rec. 2020 color primaries.
