Ok so I got home, and since I know that at least for RGB 16-bit images pixels are scaled to 65535, I wanted to make sure that this 256-factor for YUV is not just some shit from MS. I fired up the bt709 spec, and it's true. While I haven't found a direct mention of how to scale to larger bitdepths (it doesn't define 16bit at all, only 10), it still implies simple power-of-two factors simply from the allowed data ranges in 8- and 10-bits. So I guess we should switch to this scale too. EDIT: Oh, I see pinterf already changed it. Good work :thumbs up:
