for computer work, sure, but for movies?
do you know digital movie projection (in true cinemas) is only 1920x1080? (in fact just a bit more, true 2k, but the difference is null)
Only that? What a shame. I read recently that the digital master of a movie is some petabytes in size. It is so big an unwieldy to copy (just consider transfer datarate of gigabyte network; even fiber is slow), that for archival they store film copies, one tape per colour (ie, each film is B/W), and keep 3 copies of each, on different buildings, I hope. Meaning 9 B/W film "rolls". They do not trust digital copies. They have to be recreated every five years or so, worst that papyrus. Digital archives are very expensive to keep... Those 9 rolls above are cheaper by a order of 10 or so, and last a century, proven. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
