Interactive Transcripts

Scope of support

Radiant Media Player supports interactive transcripts in the following format:

  • Side-loaded WebVTT transcript file for on-demand video. WebVTT file is passed to the player through the transcript player setting.

The interactive transcripts will be displayed in a side menu at the right of the player.

While the WebVTT transcript file can be different from the WebVTT closed captions file passed through the ccFiles setting, you can use the same file for both to add transcript and closed caption to the player
