H.264: The New Video
Codec in QuickTime 7
H.264 uses the latest innovations in video compression technology to provide pristine,
high-quality video suitable for delivery across the entire bandwidth spectrum—from
3G mobile phones to Internet video conferencing (including iChat AV) to broadcast
and high definition television. Already ratified as part of the MPEG-4 standard, H.264
has also been selected as a mandatory component of both the HD-DVD and Blu-ray
format specifications for next-generation DVDs.
Apple has applied its many years of experience in developing video codecs to deliver
the industry’s best technology for both encoding for delivery and decoding for play-
back of H.264. In fact, high definition video created with Apple’s extremely efficient
H.264 encoder reduces bandwidth requirements by as much as a factor of four without
sacrificing video quality, allowing you to play back 1920-by-1080 24p high definition
video on today’s dual processor Power Mac G5. The future of digital video is built into
QuickTime 7 in Tiger.
