Zoom has become the go to way to keep in touch and run webinars, it is also great for teaching and doing demos. Now you can make it even more useful when teaching or doing that demo by having your presentation as your virtual background, and it works whether it is PowerPoint or Keynote.
I must admit I really like this as you can move how you appear over the background, so you can be full screen and then point at the slides just like they do in a weather forecast, or you can shrink yourself down into a corner, any corner, or anywhere on the screen. So the only thing is that it doesn’t allow you to use the animation or transitions you have in your presentations but I think you will agree this is so engaging you may not need it. As for video you have embedded that doesn’t work either but you can play that separately using the share screen option.
Here’s a video I made to show you how to use it.
