How can I export my PowerPoint presentation to MP4 on a Windows device?
Answer
You can export to MP4 from within PowerPoint via File>Export>Create Video.
If you have recorded your slide show and added narration via Slide Show > Record Slide Show, you can export it to an MP4 with narration.
Select "Use Recording Timings and Narrations" in the drop-down (see screenshot below).
If you are exporting without narration, select "Don't Use Recording Timings and Narrations" and set each slide's 'recording' time.
In the example below, it is set for 5 seconds (05:00) per slide.
