Here are some images from my visit to Sony's Color Works studios:
This is how they scan the film tape (to 4k or 8k resolution):
Scanned frames are then edited for color balance, missing frames, dust removal etc:
Over 1PB (petabyte) of storage - this is just for the editing/remastering:
The end result is a 4k classic movie, which can be transfered (downsampled) to 'Remastered in 4k BD' or uploaded in native 4k to Sony $699 FMP-X1 4K media player:
