ITU-R UHDTV Standard, the mainstream 4K TV standard, use Rec 2020. In theory you can use any color primaries with any video resolution in computer (NOT on TV as those normally only support mainstream standard) as long as the the color space metadata is properly set, but in practise, some softwares ignore the metadata or the metadata got lost in the video processing chain. So in general, 4K video use Rec 2020, HD/FHD use Rec 709, and SD use Rec 601, for maximum compatibility. |
