How to make a TTML file
TTML files are in XML format. They are a much more elaborate and configurable way to provide Closed Captions for your stream content, in comparison with SRT files.
Requirements:
- Name the .ttml file the same as the video file you are providing subtitles for
- Ensure the file is uploaded to the same directory as the video content
