Using Apple Compressor
Matrox MAX technology also supports the 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 to the
encoded video file (.mov).
Assigning a Matrox MAX H.264 setting
This section describes how to assign a Matrox MAX H.264 setting to your source
file in Apple Compressor. The Matrox MAX H.264 settings include the
predefined settings installed with your MXO2 software, and any custom settings
that you create (see “Creating a custom Matrox MAX H.264 setting” on
page 104).
¦NoteWhen selecting a predefined Matrox MAX H.264 setting, any
modifications made to your source video’s frame size in your application must be
taken into consideration. For example, if your source video was cropped in your
application, your source video’s frame size is the cropped frame size and not the
original frame size.
The predefined Matrox MAX H.264 settings that are installed with your MXO2
software are located in Compressor’s
Settings window, under Custom >
Matrox MAX H.264 Settings
. The predefined Matrox MAX H.264 settings are
separated into three folders: Blu-ray, Fast Encode, and High-Quality:
•
Blu-ray Use these settings for all Blu-ray deliverables. The encoded file’s
extension will be .264.
¦NoteFor compatibility with most Blu-ray players and Adobe Encore CS5,
the predefined Matrox MAX H.264 settings for Blu-ray use a simple GOP
structure.
•
Fast Encode Use these settings for fast encoding of QuickTime files.
These settings leverage your system’s resources with the MXO2 hardware,
resulting in even faster encoding times. The encoded file’s extension will be
.mov.
¦NoteIf your source video must be scaled for encoding and its aspect ratio
does not match the compression aspect ratio, with Compressor v3.5 or later,
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.
