I agree that my short-term solution poses a security risk, but the inability
to play my archived movies had effectively deleted my work product from
1999-2004. This was not recoverable without reinstalling an earlier version
of the OS in order to downgrade Quicktime. Obviously, this is not the best
strategy.
Apple explicitly advertises legacy support for _all_ previous Quicktime
codecs. This is an extremely appealing feature when legacy access to old
scientific data is at issue. However, this is currently false. If Apple
intends to discontinue/disable old codecs, they should make this apparent in
the upgrade notes, so that users may convert their movies _before_ their
ability to convert them is deleted.
I cannot imagine any sane individual who would enjoy the prospect of
retroactively re-encoding 5 years worth of compiled imaging data solely to
maintain legacy access.
So, I seek advice: Are there industry-standard lossless codecs that are
expected to be supported for 10-20 years? What are the best options for
long-term storage of imaging data? What resources are available that discuss
the costs and benefits of various formats vis a vis scientific data?
Best regards,
Steve Bunnell
