How much GB or TB is 1 hour of raw uncompressed Ultra HD film?
A 'base' value is ~33 GB per minute for 8-bit RGB at 24fps. Multiply by 1.25 for 30fps, and/or by 1.5 for 12 bits/pixel, or 1.25 for 10 bits/px.

3840x2160 = 8294400 pixels per plane  
   x 3 for RGB = 24883200 px per frame 
     x 24 fps = 597196800 px per sec 
       x 60 sec = 3.5831808 x 10^10 px per hour 
         x 8 bits per pixel, / 8 bits per byte = 3.6 x 10^10 bytes / hour 
So, roughly 33 GB per minute for 8-bit 24 fps
