Font styles for TTML

If the source captions are embedded or Teletext captions, and the output captions are TTML, you can optionally specify some of the font style information.

To specify font information

1. In the output that has the TTML captions, display the section for the captions.

2. Set Style control to Passthrough or Use_configured.

   Note that when User_configured is selected, there are actually no fields that you can configure.

The XML file for the captions includes the following style information:
