3 Captions and transcript

SRT and VTT subtitles plus a full transcript come out of the same project — ready for your LMS.

Supported File Formats

Start from the deck, document, or script you already have — not just PowerPoint.

Becomes a narrated video

Sources with visual pages. Each page becomes a scene you can retime and re-voice.

  • .pptxPowerPoint — one scene per slide, split automatically
  • .pptLegacy PowerPoint — same automatic slide split
  • .pdfPDF — one scene per page, split automatically
  • .docxWord — video output, with scenes built from the document structure

Becomes narrated audio

Script sources. There is nothing on screen to show, so these produce a voiced lesson rather than video.

  • .txtPlain text script
  • .mdMarkdown outline or lesson notes
  • .htmlExported web or LMS page
  • PasteType or paste a script straight into the wizard

Not sure which you have? Upload it — the wizard reads the file first and only offers video output when the source has pages it can render. Whichever you start from, you get the same narration controls, and every project exports subtitles and a transcript alongside the media.

FAQ

Common Questions

How does the PowerPoint to Video converter work?
Our AI analyzes your PowerPoint (PPTX) file, extracts the text and speaker notes, and automatically generates professional AI voiceovers for each slide. It then syncs the audio with your slides to create a seamless video presentation.
What file formats do you support?
For a narrated video, upload PowerPoint (.pptx, .ppt), PDF (.pdf), or Word (.docx) — anything with visual pages. PowerPoint and PDF are split into one scene per slide or page automatically. For narrated audio, you can also upload a plain-text script (.txt), Markdown (.md), or HTML (.html), or paste a script straight into the wizard; those have nothing to show on screen, so they produce a voiced lesson rather than a video. See supported file formats for the full breakdown.
Can I choose different AI voices?
Yes! You can select a realistic AI voice for every use case in 100+ languages. You can even assign different voices to different slides if needed using our Scene Studio editor.
Is the generated video editable?
Absolutely. Once the initial video is generated, it opens in our Scene Studio. Here you can change the timing, background music, or change the voiceover before exporting the final video.
Do my PowerPoint animations and transitions key preserved?
Currently, we convert slides into high-quality static images to ensure perfect synchronization with the AI voiceover. Original PowerPoint animations are not preserved.
How long does the conversion take?
It's very fast! A typical 10-slide presentation takes about 1-2 minutes to process, generate voiceovers, and compile into a video project.
Can I add background music?
Yes, our studio comes with a built-in library of royalty-free background music that you can easily add to your video to make it more engaging.
