The Mac only or *other platform* designation within in QT3 and higher does
work quite well. I have used this feature in conjunction with the QT
Colorsync filter to ensure the correct movie is presented for a given OS
platform. Pretty cool stuff. The basic gamma adjustment also works but you
get better matching when using ICC profiles, obviously. NLE and authoring
tools don't usually access these features since they are not geared towards
repurposing and compressing for given delivery market. Media Cleaner Pro is
by far the best program for accessing the scaleable and advanced features of
Quicktime.
