The standard number quoted is 18M pixels for a still frame of Kodacolor 100.
Kodachrome 25 would be even higher.  35mm movie film has about half the
image area of 35mm still; 70mm movie film has over twice the image area of
35mm still.  The data rate of a 70mm movie is thus approx:
   35M * 3 (bytes/pixel) * 24 (frames/second) or 2.52 GBytes/sec.
ShowScan, which runs 70mm film at 60fps has a data rate of ~6.3 GB/sec.
How about GaAs LUT RAMs?
