Chapter 3 Import source media 27

Associate a closed caption le with a job’s source media le

1 Click the job to show the source media le’s attributes in the Inspector window.

2 Click the Additional Information tab.

3 Click Choose, locate the closed caption le (must be a Scenarist closed caption format le, usually

with the le 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 le

to the output media les.

•

For QuickTime outputs: Compressor adds the closed caption le as a closed caption track to

the QuickTime output le. 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 le must directly relate to the timecode of

the source media le. You can open a closed caption le 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 le.

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 le and is divided

into three sections.
