The ability to schedule a video for release gives you greater flexibility in controlling your available videos. Once a scheduled video has reached its release time, it will appear in your catalog, and if you choose to, you can automatically send a notification email to all customers letting them know that new content has been added to your storefront.
Navigate to the video you want to set a release date for under Content > Videos and click Edit. Under the Publication tab, set the video to Scheduled and set Release Date.
NOTE: Video release time is in the timezone selected in your site's Settings tab.
If you want to notify all customers that new content is available, toggle the Send email notification and update the email subject and body.
