From Microsoft Support: You can record your PowerPoint presentation—or a single slide—and capture voice, ink gestures, and your video presence. When completed, it’s like any other presentation. You can play it for your audience in a Slide Show or you can save the presentation as a video file. So, instead of just “handing the deck” to someone, people can see your presentation with the passion and personality intact. (source:
