The Compressor MPEG-2 encoder can create MPEG-2 video streams for the DVD-Video
format. To create DVD-Video discs, you can use a DVD authoring application in conjunction
with Compressor, or you can use the Create DVD job action, which is part of the Create
DVD template. See About Job Actions and About the Batch Template Chooser for more
information.
About High Definition Sources and MPEG-2
Compressor has several different options and workflows for transcoding high definition
(HD) video source files into MPEG-2 files.
HD on Blu-ray
Compressor can output MPEG-2 files for creating HD-resolution Blu-ray discs from either
HD or standard definition (SD) source media. Compressor can retain the various frame
sizes and frame rates of high definition video when transcoding to MPEG-2. And
Compressor supports the higher bit rates required by the Blu-ray format. For more
information on creating output for Blu-ray discs, see Stream Usage. Also see About Job
Actions for information on adding the Blu-ray job action to a job.
Note: The other output file format option for Blu-ray discs is H.264, also known as MPEG-4
Part 10.
HD to SD Downconversion
For those situations in which you are editing high definition (HD) sources in Final Cut Pro
and want to create a standard definition (SD) DVD from them, Compressor provides
high-quality downconversion. Compressor retains as much detail as possible during
scaling and correctly preserves progressive or interlaced formats when encoding to
MPEG-2 for DVD.
To see the source media resolution and frame rate
1 Import the source media file into the Batch window.
2 Click the source’s name in the Batch window.
The source media file’s resolution and frame rate, along with its duration, appear in the
lower-left corner of the Preview window.
About Elementary, Transport, and Program Streams
There are three common MPEG-2 stream types that are used to deliver MPEG-2 encoded
video.
• Elementary streams: These streams contain only one MPEG-2 content channel and no
audio.
