Apple has posted a selection of sample multimedia clips for QuickTime 6 Public Preview users.
The collection offers real examples for QuickTime 6 users of what MPEG-4 and AAC audio can do. This version of QuickTime 6 implements an Instant-On mode, so users don't have to wait for entire movies to download or buffering operations to complete. It's also possible to scrub between frames of video on-the-fly.
The site also features links to Apple's content-creation partners, including Epic Records (a Sony label that employs Key2Audio technology).
QuickTime 6 features next generation MPEG-4 video support, with AAC (Advanced Audio Coding) technology.
MPEG-4 Video offers compression-times and video-quality rivalling those of the best proprietary codecs, yet works with other MPEG-4 players and devices.
AAC Audio (Advanced Audio Coding) is a new standard in professional audio, offering more efficient compression than formats such as MP3, for near CD quality.
