Import and preview captions in Compressor
In a standard transcoding job in Compressor, you can add a single set of CEA-608 closed captions, iTT subtitles, or SRT subtitles by adding a .scc file, a .itt file, or a .srt file to the job. If a source video file already has embedded CEA-608 closed captions, when you add the source file to a batch, Compressor extracts the .scc data for you.
Note: In an iTunes Store package, you can add multiple CEA-608 closed caption sets and multiple iTT subtitle sets (in several different languages, for example). For information about adding closed captions and subtitles to iTunes Store packages, see Build iTunes Store packages using Compressor.
Add a captions text file to a job
After you add a job to Compressor, you can add a captions text file created by a third-party app.
In the Compressor batch area, click Set on the right side of the Captions row.
In the window that appears, select a CEA-608 closed-caption file (with a .scc filename extension), an iTT subtitle file (with a .itt filename extension), or an SRT subtitle file (with a .srt filename extension), then click Open.
Note: In a standard Compressor job, you can import only a single captions file.
The row under the Captions heading in the batch area displays the filename of the imported captions file.
For information about formatting and modifying captions in Compressor, see Edit caption properties in Compressor and Adjust caption timing in Compressor.
Add a source video file with embedded CEA-608 captions
If a source video file already contains embedded CEA-608 closed captions, importing the video into Compressor automatically adds the caption data to the job.
In Compressor, click the Add pop-up menu
under the batch area, then choose Add File.In the file window that appears, select a media file that contains embedded CEA-608 closed captions, then click Add.
The batch area displays a new job, with the source video file shown above an identically named captions file.
