Support for Font Styles in Output Captions

Depending on the scenario, there are three possibilities for the font style for output captions:

  • You can specify the style you want for fonts, including color, outline, and background color.

  • The font styles in the input are passed through.

  • The font styles are controlled by the downstream player.
