I want to reiterate that the ProRes codec is lossy. ProRes 4444 is
the best, it's full 4:4:4 color sampling and can optionally preserve
RGB color space if you're working with graphics. But if you're
looking for a truly lossless mastering format, the best option is
still Quicktime Animation at 100% quality. /// Aaron

I agree. HDCam-SR is a preferable tape master (but expensive to read
from because only big labs have the players). A ProRes file is
definitely more useful to work with, though a physical tape master
is reassuring to have. 24PFS is the most compatible framerate for
film original and HD projection including DCP. If you then make a
downconverted SD version on beta or as an SD file then 25fps is the
standard for that version. Watch out for DCP - this is an encoded
file package like a DVD and certainly not a master element. It
cannot be accessed or copied. It cannot even be read from in real
time - it has to be ingested into the server. It is only useful for
screenings in cinemas that are equipped. You are right to worry
about servers and platforms - some DCPs don't play on all systems.
But DCP has become the Hollywood standard to replace release prints.
It is handy to have available for potential screenings an HD ProRes
file, a Blu-Ray disc, and/or a DCP, an SD file, a beta, a DVD... But
for preservation, archiving and future compatibility,the best master
now is a 2K file, either in DPX or ProRes 4:4:4 or as tiff images.
Down the road you will be able to convert that into anything you
will need and you could even make a 35mm negative from it, which is
the best solution of course. -Pip At 16:28 -0800 12/12/13, David
