Instructors can use presentations from PowerPoint or Keynote to create video lectures for their courses, provided that they include audio narration and are converted into a video file format (MP4, WMV, or MOV files).
This article is quite helpful as it thoroughly explains how you can convert presentations from PowerPoint and Keynote into video lectures for your course.
Converting a PowerPoint presentation into a video lecture
If you have created a presentation in PowerPoint and want to turn it into a video with narration, you can do this without any additional software. This feature is available in PowerPoint 2010 and later versions.
How to record a narration
You can add an audio to your PowerPoint slides by following the easy steps below:
-
Under the Slideshow tab, choose Record Slideshow.
-
This will launch the presentation, and it will record your narration through whatever is set as the default microphone on your computer. Just be sure to test that the audio is being picked up by external mics.
-
Go through your presentation normally and it will record the entire session moving forward. Be aware that under the same Record Slideshow dropdown, you can record over individual slides if you accidentally make a mistake.

Saving the presentation as a video
Once you have recorded your narration, you can convert your PowerPoint presentation into a video by using the Create Video settings. Be sure to save your file as both a PowerPoint file and a video file so you will still be able to go back and edit the PowerPoint later on if you need to.
