# How to turn a script into a captioned video

Updated 2026-11-09

To turn text into a video, voice the script and show it as captions over a background. Text to Video does this from a script of up to 3,000 characters and exports an MP4. Everything runs in your browser and nothing is uploaded. It is not generated footage. The picture stays still behind the captions.

## Make a video from a script

Write the script first. What you type is both the narration and the caption text.

1. Paste your script and pick a language and voice.
2. Choose landscape, vertical or square, and add a background picture if you have one.
3. Make the video, then download the MP4.

## What the video looks like

You get captions over a plain dark background, or over a picture you add. Sizes are 1280 x 720, 720 x 1280 or 720 x 720. No scenes, stock clips or animated characters are made. If your idea needs moving footage, this tool does not supply it.

## How the captions line up with the voice

Each sentence is voiced on its own. The measured length of that audio sets when its caption appears. A long sentence is split across several caption cards, shared out by length.

Short sentences make cleaner captions. Break up a long one before you run it.

Read the finished video once with the sound on. If a caption card holds too many words, shorten that sentence in the script and make the video again.

## Where your script goes

Nowhere. The voice runs in your browser and the script never leaves your computer. The voice model downloads on first use, about 86 MB, or 20 MB for German. Each run counts toward the 5 free AI runs shared across tools in any rolling 24 hours.

## Questions

### Can I edit the captions without changing the voice?

No. The captions come straight from your script. Edit the script and run it again to change both.

### Does it make video footage from my words?

No. It makes a voice track and captions on a still background.

### How long can the script be?

Up to 3,000 characters.
