4K 4:2:2 vs 4:2:0 color resolution difference
3

I was curious if the color resolution difference between the S1's 4:2:2 and 4:2:0 modes would be discernable so here's the first experiment I devised. I set up a multi-colored ball of thread, with the idea being it contains a lot of detailed color transition areas. I locked the S1 down on a tripod. I shot two short 4K videos @ ISO 100 - one using the 10-bit 4:2:2 codec (enabled with DMW-SFU2 key) and the other 8-bit 4:2:0 codec. Lens used was a Canon EF 50mm f/1.4 @ f/6.3 (with Sigma MC-21).

Here's a 4K screen grab of the scene:

I then took a screen grab from both the 10-bit 4:2:2 (4K 24P 150M MOV) and 8-bit 4:2:0 (4K 24P 100M MP4) footage, cropped the 128x128 center area from them, layered them in PS, then increased the size by 500% using Preserve Details 2.0, then created an animated timeline from the two and exported as an animated GIF. Click "original size" below to animate (direct link):

I'm open to ideas on ways to improve this experiment.
