Using H.264 Assets
You can use the H.264 for HD DVD presets included with Compressor to encode several
supported HD and SD video resolutions for use in your HD projects.
The H.264 encoder is twice as efficient as the standard MPEG-2 encoder. When compared
to encoding with MPEG-2, this means that with the H.264 encoder:
• You can use a lower bit rate to get the same quality, resulting in smaller files.
• You can use the same bit rate and get better quality with the same file size.
