What happens when you create a Premiere
Before your Premiere starts A public watch page is created for your video to eventually premiere on. You can share the watch page URL since the watch page is public before the Premiere begins. Premieres show up across YouTube just like regular uploads. You'll find them on search, the homepage, and video recommendations.
Note: If your account has a Community Guidelines strike, your Premiere won’t publish during the penalty period. Your Premiere is set to “private” for the penalty period duration, and you have to reschedule it when the freeze period ends. Learn more about Community Guidelines strike basics.
Watch page overview
During your Premiere
A countdown theme will start 2 minutes before your Premiere. When the countdown is over, viewers watch the video together in real time. Viewers can rewind the video, but cannot forward past what’s been shown live. You and your viewers can continue to interact in the comments and live chat.
After your Premiere ends
After your video premieres, it stays on your channel as a regular upload. The countdown theme won’t be included in your video. Chat replay is available for viewers who want to experience the Premiere chat after it has ended. You can turn off chat at any time. From YouTube Studio, you can also use YouTube Analytics to see how your Premiere performed. The view count from the Premiere will transfer to the video afterwards.
