I have a question about the color bit (depth?). Can you explain it to me like I’m a five year old? How does that differ from the resolution of the image? Is it that there are more colors to choose from, or something about how they are displayed?

In binary you only have two “numbers” to work with, 0 and 1.

8-bit is 2 to the 8th power, or 256, for each primary color. 256 cubed (since there are three primary colors: red, green, and blue) gets you a little over 16 million possible colors with 8-bit.

Extrapolate that out to 10-bit and you get billions of colors, 12-bit billions more.

If I’ve got this right, regular blu-ray still uses 8-bit color but UHD blu-ray uses 10-bit.

RotS was probably finished in 10-bit, although the actual cameras recorded in 12-bit color.

I’m not sure about TPM, AotC, or the four most recent movies, but Reliance MediaWorks’ 4k restoration of the OT was done in 16-bit. Alfonso Cuaron’s recent film Roma was also finished this way.
