The Center Stage feature uses the front-facing camera (Ultra Wide lens) to automatically keep the person (or people) on camera in frame. As the person moves around, the camera pans to follow them.
Center Stage is a feature available on the M1 iPad Pros:
11-inch iPad Pro (3rd generation and later)
12.9 inch iPad Pro (5th generation and later)
iPad Mini 6
To enable Center Stage: While using video in the Switcher Studio app,
Open the Switcher app.
Swipe down from the top-right edge of your iPad.
Tap Video Effects.
Tap Center Stage.
Now when using your front-facing camera, the subject will be kept in frame.
