Is 4k in 4:4:4 actually 16k?
Okay so I've been doing some studying on the real science behind chroma sub sampling (http://www.5dfilmmaking.com/tut_444.htm), and I realized that 1920x1080 at 4:2:0 sampling is essentially taking every 4x2 set of pixels, so 8 and turning them into two pixels right? well if so does that mean that you're effectively taking a 1920 image and reducing it to 480 then scaling it back up again? I must be misunderstanding something or is that how it works. Or is 4k at 4:4:4 showing 4 times the quality? Now I'm all confused! Help please!
