Add captions to a recorded event

Captioning 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. You can request a caption file for your event or ask your captioning provider for a compatible file.

Notes:

• Only VTT files are supported. If you previously uploaded an XML timed caption file, those captions will work, but if you remove the file - to replace it - only VTT files will be accepted.
• You can't add a caption file to a Live event. To add captions to a Live event, see Add live captioning to an event.

Once you receive the caption file, turn on Closed Captions for the event and upload the file. Captions are shown inline with the video. You can display them automatically or allow attendees to turn them on as needed. Attendees can turn captions off at any time.

Important: Captions are timed with the event audio. If you edit an event recording after receiving a caption file, the captions will be out of sync. You must request a new caption file.
