Apple's new release of QuickTime 7 provides a new video codec, live resizing and surround sound support. The new codec, H.264, is an industry standard MPEG-4 codec that will be supported in HD-DVD and Blu-ray when those next gen DVD standards appear (or merge.) Apple has also added 24 channels of surround sound to QuickTime 7, and has added new audio and video playback controls that lets a user set the bass and treble, along with speeding up or slowing down playback on the fly.
