Add captions to a recorded event

Captioning provided during a Live event is not included in the event replay. To add captions to a replay or to an On-Demand or Simulated Live event, you need a timed caption file in VTT (WebVTT) format. A timed caption file contains the text of what is said in the recording, plus time codes for when each line of text should be displayed.

Note: To learn about real-time captioning for Live events, see Add live captioning to an event.

You can offer captions for your event in different languages; just upload a separate timed caption file for each language you want to provide. Captions are displayed in the video player above the player controls. You can display them automatically or allow attendees to turn them on as needed. Attendees can turn captions off at any time.

You can submit a request for caption files for an event or ask your captioning provider for compatible files. Once you receive the files, turn on Closed Captions for the event and upload them.

Notes:

  • Only VTT files are supported. If you previously uploaded an XML timed caption file, those captions will work, but you cannot upload additional caption files while you have an XML file loaded. If you remove the XML caption file - to replace it - only VTT files will be accepted.
  • Captions are timed with the event audio. If you edit an event recording after receiving caption files, the captions will be out of sync. You must request new caption files.
