Scheduled publishing allows partners to schedule a private video to go public at a later time. The video will remain private until the specified scheduled publish time.
You can schedule a video publish time only if you set the video as private or scheduled on the upload landing page. The scheduled publishing feature allows you to precisely choose the date, time, and time zone at which you want your video to be sent to subscribers.
Go to your Video Manager page. You will see a Scheduled icon next to the video in question.
Click the Edit icon next to the scheduled video
In the Privacy settings, you can adjust the scheduled publish time accordingly, or change the video to Public to publish it immediately.
