The fact remains that what's showing in your local multiplex is at
least three generations removed from the original negative, and more
likely five. It makes no sense at all to use the original 'final cut'
master more than once - just as they did with analogue tape masters.

So, unless you're watching the film on its premiere, you're very
unlikely to be closer than five generations away from the film in the
camera. What, you think they make thousands of prints directly from 1
master negative? Consider the risk......

Not entirely. It's certainly true that it will ultimately save money,
but you have two-fold advantages of simultaneous release world-wide
possible within a day of the final edits, and also original master
quality in *every* cinema. 'Perfect vision forever' - as some
marketing droid will doubtless say..................
