Convert to High Quality Videos
After saving your presentation in .pptx, you can export the file and convert it into a video format. The 2016 PowerPoint version allows you to do this. However, in PowerPoint 2019, you can export your video as an Ultra High Definition (HD) or 4K format which you can display on large screens.
You can also save your presentation as a PowerPoint show (.ppsx), such that when people open the file, it displays in full-screen and presentation mode. They begin to see your presentation immediately.
