Post by cinemadWith 35mm film we have tried and proven preservation techniques such b/w separations, Interpositives etc.
With digital Video, every few years a new system is introduced and the former systems become obsolete.
How will we retrieve a Digital film produced in 2014 in say 2034?
If the studio that made it cared about it, they pulled B&W film separations
off the digital file, using the Fuji digital archiving stock, and put them
in a vault.
If the studio that made it cared about it, they put a file in a "digital vault"
which is regularly refreshed, in a standard format that is documented. The
format may become obsolete but as long as the format is documented it's possible
to write a decoder.
There are a lot of gotchas here on both approaches, and the Library of
Congress has been engaging people in the archive community about discussing
them. There was a really good seminar a few months ago which may have a
summary online somewhere.
The real problem, as always, comes with the films that the owners didn't care
about, but which somehow became culturally important. Every print of
Nosferatu that we have is a dupe off of one projection print that somebody
saved. For every Nosferatu there are a dozen films that were lost.
