I'm a little curious about the notion that there is some sort of Quicktime 64bit format.
Usually, Video barely makes it past 12 bits.
I suspect, but am also asking; Isn't it really the case that Quicktime, the 64 bit application, produces videos in a codec that is not available for 64 bit windows.
In other words it's not the 64bit QuickTime that is the problem... it's the codec... the codec isn't cross platform or open to other players.
I'm just pointing that out because I am reading a thread that has been populated by true working professionals and no one seems comfortable identifying the codec nor does anyone seem eager to acknowledge the fact that the confusion is created by a confusion about codecs.
The best way to achieve clarity while discussing the easiest work around will require that everyone start speaking about codecs with some familiarity. Each user will need to acquire some knowledge about how they are specifically interacting with codecs.
The problems start when a video editing professional (who rarely seems to know much about codecs either) hands a musician a video with a codec that the musician can't seem to play. The the musician seems to know that embarrassing the video editor by questioning their choice of codec isn't good for business.
The best solution is too learn all about codecs and to learn how to quickly react to any situation.
I do understand the need for quick turn around times and the undesirability of having to convert to another codec... but that is a situation forced upon us by what ever relationship we have with the video house... if the video house really cared... they would export the video in something that everyone could play. If turn around time when working with a Mac centric house is paramount... you are probably going to want to get a Mac... because nothing will be settling down in the codec wars for another decade or so.
