Finally, officially QuickTime 6 is released. I have been playing with the beta on my PowerBook and the MPEG-4 video is very nice and the AAC Audio is amazing. Apple has examples of the video and audio possibilities. The only down side is that you have to upgrade your QuickTime Pro key for QT6…but you can still export things with the new capabilities from whatever programs you use to do QuickTime stuff so it isn’t a huge issue.
