Mac OS X Tiger
Apple’s implementation of H.264 in QuickTime 7 uses a set of advanced technologies
and patent-pending techniques to create pristine video at low data rates. The H.264
encoder:
• Produces the best possible quality at the desired bit rate in an optimal number of
compression passes.
• Offers a single-pass encoding mode for preview and live encoding scenarios.
• Optimizes for streaming and CD/DVD playback with peak-constrained variable bit
rate (VBR) encoding.
• Supports advanced frame reordering (B-frames) for more efficiently representing
movie data.
• Uses improved intraframe prediction for more efficient compression of high-motion
video.
• Reduces traditional blocking and ringing artifacts even in areas of fine detail by using
a 4x4 integer transform.
• Delivers an adaptively tuned, in-loop deblocking filter for eliminating blocking arti-
facts, resulting in a smooth, clean image.
