(depending on which you selected).
You can modify the preset or create a new custom preset by clicking Edit Presets. This
opens Compressor.
5 If you are exporting a multichannel audio file, click Edit Channel Layout to open the
channel assignment dialog, choose the physical output channel for each channel in the
exported file, then click OK.

Using Compressor in Your DVD Studio Pro Project
While you can directly import QuickTime movies into DVD Studio Pro and use its
embedded 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 MPEG encoder, including a variety of GOP
structure settings.
 Encoding of 24p and HD sources for SD-based DVD projects: Compressor can encode
NTSC-resolution, 24 fps MPEG streams. Additionally, Compressor includes the ability
to perform a high-quality downconversion of HD sources, making it easy to create
high-quality traditional SD projects from Final Cut Pro movies.
 Encoding HD sources for HD-based DVD projects: Compressor can encode
uncompressed and DVCPRO HD video into the MPEG-2 or H.264 video streams that
DVD Studio Pro requires.
 Encoding AC-3 audio: Compressor can encode audio into Dolby Digital AC-3 audio
streams. Using compressed audio in your DVD projects reduces the amount of disc
space the audio requires. Since AC-3 files require a much lower bit rate than the AIFF
audio files created by the audio encoder embedded in DVD Studio Pro, they allow
you to use a higher bit rate for your video assets.
 MPEG-1 video: While MPEG-2 provides the best video quality for your SD-based 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 tracks in
your SD projects.
