A Microsoft file hosting and synchronization service.
To export a PowerPoint as a video:
- Open the presentation and select File > Save first.
- Go to File > Export > Create a Video.
- In some versions, the Recording tab also has Export to Video.
- Choose a video quality:
- Ultra HD (4K)
- Full HD (1080p)
- HD (720p)
- Standard (480p)
- Choose whether to use Recorded Timings and Narrations.
- If no timings were recorded, PowerPoint uses 5 seconds per slide by default.
- That value can be changed in Seconds to spend on each slide.
- Select Create Video.
- Save the file.
Useful notes:
- PowerPoint can save the presentation as .mp4 or .wmv.
- Animations, transitions, narration, and laser pointer movements can be included in the video.
- Viewers do not need PowerPoint installed to watch the exported video.
- Video creation can take longer for large presentations or presentations with media.
For the Windows Security / docs.live.net prompt: the provided material does not include a documented fix for that sign-in prompt. If the presentation is stored in OneDrive, saving a local copy first and then using File > Export > Create a Video is the closest supported path in the available material.
