QuickTime goes High Definition:

“The DVD Forum has ratified the H.264 Avanced Video Codec(AVC) – which Apple will ship in it’s QuickTime software later this year – to be included in the next generation High Definition(HD) DVD format.

“Apple first displayed H.264 at NAB earlier this year. MacCentral described H.264—or MPEG-4—as ‘an advanced HD video codec that, unlike other codecs, is scalable, allowing content creators to write content for everything from 3G phones to HD, and everything in between.’
