Exporting video to play from MacBook Pro to Apple TV via AirPlay

If you're talking about AirPlay mirroring, it sends over whatever is on your Mac screen, so if your Mac can play the video, it can be sent over AirPlay. I think this means you can export to any format and settings that your Mac can play smoothly on its own, but I could be wrong about that. To be on the safe side, export using one of the built-in presets that creates a standard H.264 video (ike the YouTube presets) and that should work fine.

If the video plays fine on your Mac but stutters on the TV, troubleshoot the wireless network connection between your Mac and the network router and the AppleTV.

If the video stutters on the Mac when you're trying to send it to the AppleTV, the Mac might be too busy trying to play the movie and send it over AirPlay at the same time. This is more likely if the Mac is older. If this happens, try exporting the video again at a lower bitrate.

In Pr, you simply export a video as a file. You'd have to figure out the connections to play it on something else, using the gear you've got & applets or such.
