Creating H.264 DVD Output Files
Compressor can output H.264, also known as MPEG-4
Part 10. This ultra-efficient, fully scalable video technology
produces higher quality video at lower data rates.
Compressor 2 adds output for H.264, also known as MPEG-4 Part 10. Not only is H.264
very efficient, providing extremely high quality in smaller files, but H.264 is also
scalable, producing video for everything from 3G for mobile phones to High Definition
(HD). H.264 is currently mandatory in both new high definition DVD specifications (HD
DVD and Blu-Ray) and functionally included in hundreds of new electronics products.
At DVD data rates, H.264 is twice as efficient as MPEG-2. That means you can count on a
lower bit rate to get the same quality, or higher quality at the same bit rate. H.264 is
the result of the combined efforts of two standards bodies — the ITU (International
Telecommunication Union) and ISO MPEG (International Organization for
Standardization’s Moving Picture Experts Group). H.264’s outstanding performance and
efficiency makes it the likely successor to MPEG-2 in the professional media industry.
