Add human-generated captions to a recorded event

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

Notes:

Once you receive the caption file, upload the file in the setup of your 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 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.
