Apple Compressor 3 - Manual (Page 87)

Additional Information Tab
The Additional Information tab allows you to see and modify a variety of metadata items
that might have been added in other applications such as Final Cut Pro or QuickTime. It
also includes the ability to associate a closed caption file with the file.
To 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 an .scc file extension), 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.
DVD Studio Pro will retain this closed caption data when the video stream is used in a
track in a standard definition NTSC DVD project. You can use Apple DVD Player to play
the DVD Studio Pro build files and verify that the closed caption data is present.
• 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.
