Chapter 10, Using the Matrox MAX H.264 Codec
you can select Preserve source aspect ratio from the Padding list in
Compressor’s Geometry pane to maintain your source video’s aspect ratio.
•
High-Quality Use these settings for high-quality encoding of QuickTime
files. With these settings, the encoding is performed entirely by the MXO2
hardware, which frees your system’s resources for other tasks. The encoded
file’s extension will be .mov.
°To assign a Matrox MAX H.264 setting:
1 In Apple Compressor, add the source media file that you want to export as an
H.264 file to the
Batch window in Compressor.
2 Drag the desired Matrox MAX H.264 setting from the Settings window to
your source media file (job) in the
Batch window.
¦NoteMatrox MAX technology supports closed caption data from SCC files
for web deliverables (.mov) when encoding at 1:1, or when downscaling. When
an SCC (CEA-608) closed caption file is associated with your source media
file in Compressor, Matrox MAX technology embeds the closed caption data
in the encoded video file (.mov).
3 If you’re exporting to Blu-ray format and you want to export audio as well,
you must add a separate audio setting to your
Batch window. Matrox
provides predefined audio settings for each of the Matrox settings, however,
you can choose to use another audio setting.
4 Choose a destination for your job’s targets and submit your batch as you
would normally.
Creating a custom Matrox MAX H.264 setting
You can create a custom Matrox MAX H.264 setting in Apple Compressor for
delivering H.264 files for either Blu-ray (.264) or QuickTime (.mov). Once you
create a new Matrox MAX H.264 setting, you can assign it to your source file in
Apple Compressor using the steps described in “Assigning a Matrox MAX H.264
setting” on page 131.
¡ Important To avoid losing your custom Matrox MAX H.264 settings in
Compressor when updating your MXO2 software, you must uninstall the MXO2
software that is installed on your system, restart your computer, and then install
the new MXO2 software version before opening Compressor. If you open
Compressor before installing the new MXO2 software, that is, with no MXO2
software installed on your computer, your custom Matrox MAX H.264 settings
will be deleted by Compressor.
