How to use closed captioning
In version 4.0.0, S3 Media Maestro supports closed captioning via VTT file. You can use services like Temi to generate the closed caption file (VTT) in order to apply it to a video.
- Once you've selected a single video, click the Closed Captions tab.
- Click Select File in order to select or upload a VTT file.
- Select the language of the VTT file.
- If you have more than one language, click the plus symbol to add another closed caption.
[NOTE] Closed captions are not supported with playlists.
When a viewer plays a video, a closed caption toggle appears on the video player.
