>since YUV420 really messes up red text in screen captures for example
Is there an detailed explanation why red is especially bad after chroma subsampling? Have been wondering about this for awhile.
I assume it's because red has low brightness/luminance (no idea if correct or not)?
- klodolph 4y agoYes, it’s because red is dim. Dark blue (like, RGB 0, 0, 255) also suffers, perhaps worse, but that shade of blue is hard to reaf even when it is reproduced perfectly.
