Play web videos in Safari on Mac
With Picture in Picture, you can play a video in a movable window that “floats” on top of everything else, so you can always see it, no matter what you’re doing. With AirPlay, you can play web videos on any HDTV with Apple TV—without showing everything else on your desktop.
Play a web video with Picture in Picture
In the Safari app on your Mac, navigate to the web video you want to play.
Click and hold the Audio button in the Smart Search field or in a tab.
Choose Enter Picture-in-Picture.
You can drag the window to any corner of the screen and the window stays put, even if you switch desktop spaces. You can resize the window to see more or less of what’s behind it.
