Create Blu-ray discs
Compressor includes the ability to easily create H.264 settings specifically configured for Blu-ray
and AVCHD discs.
Blu-ray, also known as Blu-ray Disc (BD), is a format that was developed to enable recording,
rewriting, and playback of high-definition (HD) video. The format offers more than five times the
storage capacity of traditional DVDs and can hold up to 25 GB on a single-layer disc and 50 GB
on a dual-layer disc.
An AVCHD disc can be thought of as a simpler HD disc that is burned to red laser media. The
resulting disc plays in Blu-ray Disc players that are compatible with the AVCHD format.
The efficiency and quality of H.264 creates a number of options for optical disc producers:
•
Video resolutions supported by standard-definition (SD) DVDs are also supported by Blu-ray
Disc. This means that a Blu-ray disc can use an HD video resolution file for its main content,
such as a feature film, and then use SD video resolution files for additional features like trailers
and a “making of” documentary.
•
The Create Blu-ray Disc job action can be used to burn an AVCHD disc using red laser media.
An AVCHD disc provides a way to play H.264 video in Blu-ray Disc players that are compatible
with the AVCHD format.
•
Because H.264 can deliver HD video at SD bit rates, you can get more HD content on a regular
DVD-5 disc than you might expect for an AVCHD disc.
