After you’ve set up your Stripe, Braintree or Recurly info and completed the Purchase & Rental setup, you will be prompted to turn “purchase” or “rental” on for all of your videos.
To manage these settings for each video, go to the “Library” in the sidebar navigation and select the video you want to edit. Then click on the “Monetization” tab to edit the settings for your video.
Use the "Require Purchase" or "Require Rental" toggles to setup the type of monetization for this specific video. You're also able to edit the default pricing and rental duration. Once you've set the pricing click "Save" at the bottom of the page.
