What are Captions and Subtitles?

You can only have one Caption file per video as they can only be in the language of the performance in the video. Meanwhile, Subtitles are in languages other than the audio language of the video, so multiple files can be associated with one video.

All Caption and Subtitle files must be in a .ttml or .srt format.
