- Scenario
- Transforming an older slide show presentation into a playable MP4 video file for easier sharing or playback without presentation software.
- Observed behavior
- The user needs a method to save or export their slide show as an MP4, which requires specific desktop versions of the presentation software that support the video export feature.
Ensure you have a supported desktop version of Microsoft Office or a capable alternative installed, as free web-based versions generally do not support exporting presentations to video formats.
Export to MP4 Using PowerPoint Desktop
Use the built-in video export feature available in compatible Microsoft Office desktop applications to save your presentation as an MP4.
This method requires a supported desktop edition, such as Microsoft 365, Office 2021, or Office 2024. The Export option is generally unavailable in the free web version.
Launch your PowerPoint desktop application and open the older Slide Show file.
Click on 'File' and choose 'Save As'. Save the slide show as a standard PPTX presentation file to ensure all modern features are supported.
Go to 'File' in the top ribbon menu, click on 'Export', and then select 'Create a Video'.
Choose your desired video quality settings, click the 'Create Video' button, and select MP4 as the file format in the save dialog prompt.
Use WPS Presentation to Export Slide Shows to MP4
WPS Office offers a powerful and free alternative for opening older PowerPoint slide shows and seamlessly exporting them directly to MP4 video format, bypassing the need for a premium Microsoft 365 subscription.
- 1. Open your file in WPS Presentation: Launch WPS Office and open your older PowerPoint Slide Show file.
- 2. Navigate to the Tools menu: Click on the 'Tools' tab located in the top ribbon interface.
- 3. Select Export to Video: Click on 'Export to Video' or 'Video Export' from the available tool options.

Frequently Asked Questions
Can I convert a PowerPoint slide show to MP4 using PowerPoint for the Web?
No, the free web version of Microsoft PowerPoint does not support exporting presentations to video formats. You must use a compatible desktop version or a free alternative like WPS Office.
Why is the 'Create a Video' option missing in my PowerPoint?
The 'Create a Video' option is only available in supported desktop editions such as Microsoft 365, Office 2021, and Office 2024. If you are using an older one-time purchase version, a basic student version, or the web app, this feature may be missing.
Do I need to convert a PPS file to PPTX before exporting to video?
Yes, it is highly recommended to open your older slide show (PPS/PPSX) and use 'Save As' to convert it into a standard PPTX format first. This ensures maximum compatibility and preserves your timings and animations before exporting to MP4.
