When publishing a collection, you may want to include a trailer to encourage potential customers to subscribe or purchase the collection. For collections with trailers, the watch trailer button will appear for all potential customers as well as signed in customers and subscribers.
To add a trailer to a video, navigate to the Collections tab and click Edit on the collection that needs a trailer. Click on Appearance and from there you can click Choose Video to add the trailer of your choice.
The Watch Trailer button will appear on the program page under the video player
