It's kind of interesting, but damn this guy cannot communicate effectively. Was the point that > 8 bits of colour in HDMI is a good idea? That modern displays can't show them (I don't think this is true). Is his example image really suffering from being 8-bit colour, because it looks like it was exaggerated by setting the quantizer steps really big. There's also no real discussion or example of what chroma subsampling looks like.
