How do I add captions to Arc media in Canvas?
You can add one caption file to video or audio file that you own in Arc. The most common file type is an SRT file, though Arc also support VTT files, which are more user-friendly for mobile devices.
If you need help creating a captioned file, you can use a captioning site such as Amara to easily create captions for your video or audio files.
Note: Currently Arc only supports one caption file per media upload.
