John Wilson Oct 19, 2026 868 views

Question details

The user is trying to export a presentation with embedded audio to a video format but encounters a recurring popping sound in the output file.

Product: Microsoft PowerPoint (Office Standard 2019)
Device & OS: not provided
Scenario: Exporting a PowerPoint presentation containing background audio as an MP4 or WMV video file.
Observed behavior: The exported video contains a recurring audio pop approximately every 20 seconds, despite the original audio and normal presentation playback functioning perfectly.

Before you start

Verify that your original audio files (MP3, WAV, or WMA) do not contain any underlying glitches, and ensure your system's audio and video drivers are fully up to date before exporting the presentation.

Solution 1Recommended

Test with a New Blank Presentation

Determine if the issue is tied to a corrupted presentation file or a global application glitch by testing the audio in a completely fresh file.

Sometimes, hidden file corruption within an older PowerPoint presentation can cause audio synchronization and rendering issues during export. Recreating a minimal version of the file helps isolate the problem.

Create a New Presentation

Open PowerPoint and go to File > New > Blank Presentation.

Insert the Audio

Navigate to the Insert tab, select Audio > Audio on My PC, and choose one of the songs you want to test.

Export to Video

Go to File > Export > Create a Video, select your preferred resolution, and click 'Create Video' to save it as an MP4.

Review the Output

Play the newly exported video to check if the 20-second audio pop still occurs.

File Corruption Check: If the new video exports perfectly, your original presentation file may be corrupted. You may need to copy your slides into a new presentation to fix the issue.

Solution 2

Check for Office Updates or Upgrade

Since this specific audio glitch is a known issue in some builds of Office Standard 2019 but not in Microsoft 365, updating your software may resolve it.

Solution 3

Submit a Sample File to Microsoft Q&A

If standard troubleshooting fails, engaging with specialized Microsoft engineers using a sample file can help diagnose version-specific bugs.

Export Presentations to Video Without Audio Glitches Using WPS Office

If Microsoft PowerPoint 2019 continues to produce audio pops during video export, you can open your presentation in WPS Office and use its built-in Export to Video feature for a flawless MP4 output.

1. Open Your Presentation: Launch WPS Presentation and open your existing .pptx file that contains the audio.
2. Access the Export Menu: Navigate to the 'Tools' tab located on the top ribbon.
3. Select Video Export: Click on 'Export to Video' from the available tool options.
4. Configure Settings: Choose your desired video resolution (such as 1080p or 720p) and select the output destination on your computer.
5. Export the Video: Click the 'Export' button. WPS Office will cleanly render the slides and audio into a final video file without recurring pops.

Frequently Asked Questions

Why does my PowerPoint video export have audio popping sounds?

This is often caused by encoding bugs specific to certain standalone Office versions (like Office Standard 2019), conflicts with hardware acceleration, or sample rate mismatches during the MP4/WMV rendering process.

Does the audio format affect the PowerPoint video export quality?

Yes. While PowerPoint supports MP3, WAV, and WMA, heavily compressed or variable bitrate (VBR) audio files can sometimes cause syncing or popping issues during export. Converting your audio to a standard constant bitrate WAV format before inserting it may resolve the glitch.

Will upgrading to a newer Office version fix the audio pop issue?

It is highly likely. Testing indicates that this specific 20-second audio pop issue is not reproducible in the newer Microsoft 365 subscription versions, suggesting it is a bug isolated to older standalone releases.
