- Product
- Microsoft PowerPoint
- Device & OS
- not provided
- Scenario
- Exporting a slide presentation as a 1080p high-definition video.
- Observed behavior
- The exported video contains random one-frame flashes with extremely bright or incorrect colors. The affected frames change location each time the video is exported.
Check your Microsoft Office build type to see if you are enrolled in the Office Insider or Beta program, as these preview versions often contain unstable features that affect video rendering.
Update Microsoft 365 and Check Build Version
Installing the latest official updates can resolve rendering bugs present in earlier or beta builds of PowerPoint.
Rendering issues like random colored flashes are frequently tied to specific versions of the Microsoft 365 suite, particularly Version 2306 or Office Insider beta builds. Updating to the latest stable release often patches these video encoding anomalies.
Open PowerPoint, click on 'File' in the top left corner, and navigate to 'Account' at the bottom of the left-hand menu.
Look under the 'Product Information' section to see if your subscription is listed as a Beta Channel or Office Insider build.
Click the 'Update Options' button next to Office Updates and select 'Update Now' from the drop-down menu to install the latest stable version.
Once the update is complete, restart PowerPoint and attempt to export your presentation as a 1080p video again.
Report the Issue via Microsoft Feedback
If the issue persists on the latest stable build, report it to Microsoft with your exact version details so they can investigate and issue a patch.
Export Presentations to Video Seamlessly with WPS Office

- 3. Export to Video: Click on 'Export to Video' and select your preferred resolution to convert your slides into a stable video format.
Frequently Asked Questions
Why do random flashes only appear when exporting my PowerPoint presentation to video?
This is usually a rendering bug within specific Microsoft Office versions, especially Beta or Insider builds, where the video encoding engine fails to process certain slide transitions or hardware rendering tasks correctly.
Can changing the video resolution prevent the incorrect colors?
Sometimes exporting the video at a different resolution, such as 720p instead of 1080p, or 4K, can bypass the specific encoding glitch, though updating your Office software is the best long-term fix.
Will turning off hardware graphics acceleration fix the video export issue?
Disabling hardware graphics acceleration in PowerPoint's Advanced options can occasionally resolve rendering glitches and flashing frames during video exports by forcing software-based encoding.
