Setting up captions​

To set up captions for a channel, you will first need to create a captions configuration.

  1. In the Pop-up FAST Channels front-end, click your email address in the top right corner, then "Configurations"
  2. Next to "Captions", click "Create captions config"
  3. Under "Name", enter a name for your captions configuration
  4. Under "Caption tracks", click "Add caption track"
  5. Under "Language", enter the 3-letter ISO 639-2 language code of the caption track
  6. Under "Label", enter the label to use for the caption track
  7. Repeat steps 4 to 6 for each caption track
  8. Click "Save"

You can then select this captions configuration when creating a channel.

The Pop-up FAST Channels system will try to match your configured caption tracks with the caption tracks on your JWP VODs. If it cannot find a caption track to use, it will insert a blank caption track to avoid any playback issues.
