Compressor
Compressor provides an essential part of the video compression process (transcoding)
by making compression fast, efficient, and convenient and giving you more options in
your choices of compression presets, settings, and output formats.

Exporting From Final Cut Pro HD to Compressor
Compressor converts QuickTime movies to the following formats:
•
For DVD: MPEG-1 and MPEG-2
•
For web: MPEG-1 and MPEG-4
Using Compressor, you can generate high-quality video and audio assets to import into
DVD Studio Pro. If you have added compression and chapter markers in your
Final Cut Pro HD sequence, these can be included in the resulting MPEG files. You can
also add these markers within Compressor. When imported into DVD Studio Pro, the
chapter markers automatically appear in the Track Editor.

To export from Final Cut Pro HD to Compressor:
1
In the Browser, select a sequence you want to export to DVD Studio Pro.
2
Choose File > Export > Compressor.
Compressor opens with the sequence you exported from Final Cut Pro HD as a source
in its Batch window. You can then choose an existing preset or create a custom one
that will provide the level of quality your movie requires.

Exporting From Compressor to DVD Studio Pro
While you can directly import QuickTime movies into DVD Studio Pro and use its
embedded QuickTime MPEG Encoder to create MPEG video from the movies, using
Compressor provides additional flexibility in the encoding process. The benefits you
can get from using Compressor to encode your DVD Studio Pro assets include:

Additional encoding settings: Compressor includes several MPEG encoding settings
that are not available with the embedded QuickTime MPEG Encoder, including a
variety of GOP structure settings.

•
Encoding of 24P and HD sources: Compressor can encode NTSC resolution 24 fps
MPEG streams. Additionally, Compressor includes the ability to perform a high-
quality down-conversion of HD sources, making it easy to create high-quality DVD
projects from Final Cut Pro HD movies.

•
MPEG-1 video: While MPEG-2 provides the best video quality for your DVD projects,
MPEG-1 can be an alternative for specialized projects requiring more video to fit on
the DVD. The MPEG-1 format’s lower resolution and bit rate create much smaller files
than you would get using the MPEG-2 encoder. Compressor can create MPEG-1 video
files that DVD Studio Pro can import and use as assets for both tracks and menus.

MPEG-1 Layer 2 audio: Compressor includes the ability to create compressed stereo
audio files in the DVD-compliant MPEG-1 Layer 2 audio format. Using compressed
audio in your DVD projects reduces the amount of disc space the audio will require.
