How do I play video through a projector without seeing the player buttons? This is probably one of those questions with a really easy answer but either I'm not phrasing it right or there isn't a way to do what I'm wanting. At my church, we occasionally play videos from a MacBook Pro or our new 2019 iMac. The video pipes out to the projector just fine, everything works fine. 
The issue is when a video needs to be played or paused 300 people can see the mouse move over the Quicktime player's play/pause button. This seems very amateur hour but for the life of me I can't figure out how to play and pause a video in the booth without the buttons showing up on the projector screen.
I feel like I saw a video on how do do this years ago, but I haven't been able to figure it out.
Can this be done?
Thanks!
Both Quicktime Player &amp; VLC will show the cursor &amp; transport if you move the mouse, but both will respond to a simple Spacebar tap to play/pause without showing the interface. VLC has an optional || or > indicator.

If you never need to use playlists or run consecutive movies, then stick with Quicktime Player, otherwise, VLC is a much more comprehensive structure.
