Hello.
Thanks for reading my topic.
I see enconders have options to select an color format for color primaries , color transfer and color space.
I see for 720P and 1080P the color format is bt709.
Thus for better quality the correct is choice the same color format bt709 for color primaries, color transfer and color space ?
Selecting the same color format optimize the enconding compression ? Selecting alternate colors format for the same video file can break the quality ?

Have an nice week.
