New H.265 twice as efficient as H.264!

With all of the talk of expanded color space and chroma subsampling, I was a bit lost so I did a bit of research.

The color space bit makes sense as you are expanding the range of colors that the display can show. Having 10 bit color vs 8 bit means you can have a more nuanced color display. However, I was really lost when it came to 4:4:4 vs 4:2:0, etc.

So, here are some good primers on the subject.

What is YUV color?
What is 4:4:4 (chroma subsampling)?
