Dan brings up a good middle-ground. With QT's movie alternates you can make
separate movies with different settings, and have the QT pick the right one
based on the platform the user is on. These could be with different QT
ColorSync effects on them, or just versions rendered with differing
gamma/color balance.
On the more basic level, the work we did back in the QT3 days turns out to
be incomplete. QT3 was a big, painful release (the first release with
cross-platform parity), and a lot of good things got scrapped in order to
ship the basic core.
The idea was that you could tag a movie with different desired gamma
settings for different platforms, and the codec would pay attention to that
when decompressing the image data. We're looking at it again, but this
approach does limit you to certain codecs which support it. Still, that may
be ok, if the codecs available to you are good ones.
