- Google Slides cannot export a video on its own; you download the deck and narrate it elsewhere.
- Download as .pptx, not PDF. Only the .pptx keeps your speaker notes.
- Check fonts after the download: unusual Google fonts can be replaced, which shifts text.
- Animations and transitions do not carry over to the video. Split build slides into separate slides.
- Review the AI-written script before you generate audio; edits are free until then.
- The result is a 720p MP4 with SRT/VTT captions and a transcript, ready for an LMS or YouTube.
The short answer
Google Slides can present a deck, but it cannot export one as a video. To turn Google Slides into a narrated video, you download the deck as a PowerPoint file, upload it to an AI narration tool, review the narration it writes, and export an MP4.
One detail decides how good the result is: the download format. This guide explains why, then walks through the process.
Why the download format matters
Google Slides offers several download formats under File → Download. Two of them can carry a deck into a narration tool, and they are not equal.
| Download as | Keeps the slides | Keeps speaker notes | Use it when |
|---|---|---|---|
| Microsoft PowerPoint (.pptx) | Yes | Yes | You want narration written from your notes (almost always) |
| PDF document (.pdf) | Yes | No | The deck has no notes, or the layout must stay pixel-exact |
The narration for each slide is written from that slide's content and its speaker notes. A PDF keeps the slides but drops the notes, so the AI has only the text on the slide to work from. Download as .pptx unless you have a reason not to.
Before you download: tidy the deck
- Add speaker notes to the important slides. Two to four plain sentences on what the learner should understand is enough. See how to turn speaker notes into narration for what makes notes work well.
- Split build slides. Animations and transitions do not carry over to the video, because each slide becomes a still scene. A slide that reveals points one by one should become one slide per point.
- Skip hidden or backup slides. Delete slides you would not present, or move them to a separate deck.
- Use common fonts. Some Google fonts are replaced during the .pptx download, which can shift text. Standard fonts survive the trip unchanged.
Step by step: Google Slides to narrated video
Step 1: Download the deck as .pptx
In Google Slides, choose File → Download → Microsoft PowerPoint (.pptx). Open the downloaded file once and scroll through it. If any text moved or a font changed, fix it in Google Slides and download again.
Step 2: Upload it and choose the output
Start a course or training video project in Unmixr and upload the .pptx. Choose Narrated course video as the output. Each slide becomes one scene.
Step 3: Choose the language and the narrator
Pick the narration language. It can be different from the language of the deck: an English deck can be narrated in French or Hindi without translating the slides. Then choose a narrator. One voice for the whole deck usually works best; you can give individual slides a different voice later.
Step 4: Review the script
Choose Review in Scene Studio. Unmixr writes the narration for every slide from the slide and its notes, and nothing is charged until you generate the audio. Read each line next to its slide. Fix anything that changes your meaning, and check names, numbers and terms.
Step 5: Generate, listen and fix pronunciation
Generate the audio and play the first few scenes. If a name or acronym comes out wrong, add a pronunciation rule once and it applies to every slide.
Step 6: Export the video
Export the 720p MP4. It comes with SRT and VTT caption files and a transcript. Course projects on paid plans can also be packaged as SCORM for an LMS.
Where to put the finished video
- Back in Google Slides. Upload the MP4 to Google Drive, then in Slides choose Insert → Video and pick it from Drive.
- Google Classroom, Canvas, Moodle and other LMSs. Upload the MP4 and its caption file, or the SCORM package if your LMS tracks completion that way.
- YouTube or an intranet page. Upload the MP4 with the caption file so viewers get captions and search engines can read the transcript.
Common problems and fixes
| Problem | Likely cause | Fix |
|---|---|---|
| Narration ignores what you wrote in the notes | Deck was downloaded as PDF | Download as .pptx and upload again |
| Text overlaps or runs off a slide | Font replaced during download | Switch to a standard font in Slides and download again |
| A slide's points all appear at once | Animations do not carry over | Split the slide into one slide per point |
| A name is mispronounced on every slide | The voice is guessing | Add a pronunciation rule once |
| The video feels long | Too many slides or long notes | Remove backup slides, trim notes, split into modules |
Next step
Download a deck as .pptx and turn it into a narrated video. A free account exports up to 3 minutes with a small watermark, so you can try it on a real deck first. For courses with many decks, see the AI training video maker.
