How to Convert PowerPoint to MP4 Video with Narration from Speaker Notes

Can PowerPoint export MP4 videos without another tool?

PowerPoint itself can export slides as a video.

In the Windows desktop app, the usual path is File → Export → Create a Video. On Mac, choose File → Export and select MP4 or another supported video format.

If you have already recorded narration and slide timings in PowerPoint, using its built-in exporter is often the simplest route.

Presentation Video Maker is an option when you want to create narration from speaker notes or replace the recording for individual slides.

However, this tool makes a video from static slides. It does not reproduce PowerPoint object animations, native transitions, or embedded audio and video.

PowerPoint's own export capabilities also depend on the OS and version. In particular, some animations may not appear in videos exported on Mac.

What you need

You need a PowerPoint PPTX file. If your presentation uses the older PPT format, save it as PPTX first. The file-size limit is 150 MB.

Speaker notes are used as a narration script for each slide. If there are no notes, you can start with a draft based on the slide's text.

Presentation Video Maker runs in the browser, so there is no app to install or account to create.

1. Import the PPTX and inspect each slide

Open Presentation Video Maker on Browser Kitty and select your PPTX with Choose PowerPoint. You can also drag and drop the file into the app.

After import, the slides appear in a list.

Check how each slide looks. Because the app uses a different rendering process from PowerPoint, fonts, line wrapping, shapes and charts may be positioned differently.

For a presentation with a complex layout, inspect each slide before generating the video.

2. Turn speaker notes into a narration script

Select a slide to see the text imported from its speaker notes in the script field.

Speaker notes may contain bullet points or reminders meant only for the presenter. Rewrite anything that sounds unnatural when read aloud.

Check how abbreviations, technical terms and numbers should be spoken before recording.

For each slide, choose whether to include it in the video and set the pauses before and after narration.

For example, you can show the title slide briefly before the speaker starts.

3. Choose a narration method

Choose one of three narration methods for each slide. Your own voice and imported audio files work on both computers and phones.

On-device speech requires a compatible desktop. In the verified Windows Chrome/Edge workflow, select Entire screen and enable Share system audio when recording. The feature may be unavailable on other systems or browsers.

Phones can preview synthesized speech but cannot record it as a narration track. The three narration choices are:

• On-device speech: Capture the synthesized speech available on a supported computer
• My voice: Record narration through a microphone
• Audio file: Attach an existing recording

4. Prepare the recordings for every slide

After editing scripts and audio settings, prepare the narration tracks.

For on-device speech, use Record this slide one at a time or Record all scenes to process eligible slides together.

Use a microphone for your own voice, or assign an audio file separately to each slide.

Changing a script or audio setting after recording may mean you need to record it again.

The Next item to fix control takes you to a slide with missing or outdated narration. Prepare the audio for every included slide before creating the MP4.

When recording system audio, notification sounds and other applications may also be captured. Disable unnecessary alerts during recording.

5. Set video quality, subtitles and BGM

Choose 720p or 1080p for the video resolution.

1080p can make small text clearer, but it uses more device memory. On a phone, try 720p first.

Choose Cut or Fade for slide transitions.

You can include the script as subtitles within the video and add background music.

Export subtitles separately as SRT or VTT, or save just the narration script as TXT.

Subtitle timing may not align perfectly with the spoken audio, so check the subtitle preview before exporting.

6. Create, check and save the MP4

When narration and export settings are ready, choose Create video.

Video generation takes place in the browser. Compatible devices may finish quickly, while compatibility mode can take about as long as the finished video's runtime or longer.

Play the resulting MP4 before saving it.

Check slide rendering, narration cutoffs, subtitle timing and BGM volume. Make sure the final slide plays properly, then choose Save MP4.

Save a .pvm project if you stop partway through

Preparing narration can take time, especially for a presentation with many slides.

To stop and continue later, choose Save project.

The saved .pvm file contains the original PPTX, edited scripts, narration recordings, BGM and video export settings.

To resume, select Resume saved work on the opening screen and load the .pvm file.

Work is not saved automatically.

The finished MP4 is not included in the .pvm project, so save the video separately.

Can you make the video on a phone?

Supported mobile browsers can import a PPTX, create the video and save the MP4.

Use the Slides, Script & Audio and Video tabs at the bottom of the phone interface. For narration, use a microphone recording or an audio file saved on your device.

Phones cannot record on-device synthesized speech for the video. Very long presentations or high-resolution output may also exhaust available memory, so consider using a computer if necessary.

Are the PPTX and recordings uploaded to a server?

Presentation Video Maker imports the PPTX, extracts speaker notes, records audio and creates the video inside your browser.

It does not upload your selected PPTX, narration recordings or completed MP4 to Browser Kitty's servers for conversion.

Opening the hosted tool requires a download of the page itself, but that is separate from sending your file contents.

If you later upload the MP4 to a video-sharing service, that separate action sends it to the service you choose.

Summary

If narration and slide timings are already configured in PowerPoint, check its built-in video exporter first.

If you want to prepare narration from speaker notes instead, Presentation Video Maker lets you set audio for each slide and convert the deck to MP4.

After export, play the video and check both the slide images and the narration.

Tips and limitations

• Compare the result with PowerPoint's native exporter when animations, transitions or embedded media must be preserved.
• On phones, synthesized speech cannot be captured as narration. Use microphone recordings or local audio files.
• A .pvm editing project and a finished MP4 are different files; save the ones you need.
