Add live video in Keynote on iPad
You can add a live video from any of your iPad’s cameras to a slide. During a presentation, the live video plays only when the slide it’s on appears. You can turn the live video source on and off at any time.
Important: During a multi-presenter slideshow, only the cameras connected to the host’s Mac or device can be used as live video sources. To learn more about multi-presenter slideshows, see Play a slideshow with multiple presenters.
