Chapter 3 Import source media 27
Associate a closed caption file with a job’s source media file
1 Click the job to show the source media file’s attributes in the Inspector window.
2 Click the Additional Information tab.
3 Click Choose, locate the closed caption file (must be a Scenarist closed caption format file, usually
with the file extension .scc), and click Open.
Note: Closed caption data is supported by the H.264 for Apple Devices, MPEG-2, and QuickTime
Movie output formats.
Depending on the output format of the job’s target, Compressor applies the closed caption file
to the output media files.
•
For QuickTime outputs: Compressor adds the closed caption file as a closed caption track to
the QuickTime output file. You can view the closed captions using QuickTime Player (version
7.2 or later).
•
For MPEG-2 elementary stream outputs: Compressor embeds the closed caption data in an
elementary MPEG-2 video stream so that it can be used for DVD authoring.
•
For MPEG-2 program and transport stream outputs: Compressor embeds the closed caption data
in program and transport MPEG-2 streams using the EIA-708 ATSC protocol.
Important: The timecode values in the closed caption file must directly relate to the timecode of
the source media file. You can open a closed caption file in TextEdit to see the timecode values it
contains (the actual text is encoded and cannot be read this way).
Inspector window
When you select a batch’s job, the Inspector window shows you information about the job’s
source media file.
The Inspector window contains three tabs: A/V Attributes, Additional Information, and Job Action.
A/V Attributes tab
The A/V Attributes tab contains general information about the source media file and is divided
into three sections.
