Live caption requirements

Closed captions refer to the visual display of the audio in a programme. In order to live caption your event, you need to send captions to YouTube from a supported software through HTTP POSTs.

For live events that appear on US television with captions, captions may be required online as well. You may wish to review the FCC's information on this here:


Enabling Closed Captions on a Live Stream

(Requires working with one of our supported software, listed below)

  1. Create your event as you normally would. You must be using the New YouTube Live platform.
  2. At the bottom of the Ingestion Settings tab, there is a Closed Caption section. Check the box for Enable captions (requires supported software).
  3. Click in the Caption Ingestion URL box to select all and copy it. This is a signed HTTP URL.
    Each stream entry point can have one caption feed only.
  4. Provide this URL to your captioner for them to enter in their YouTube-supported caption software.
  5. Press Save.
For the best results, please ensure that your system's clock is accurate and please disable any anti-virus software that may be interfering with your captioning software.
