How does the AI Text to Video Generator work?

It runs a five-stage pipeline: your script is turned into a scene plan by a language model, each scene gets an AI-generated visual and a real text-to-speech voice-over, the scenes are drawn to a canvas with motion and subtitles, and the frames plus mixed audio are recorded into a downloadable video file.

Is the video real or just a preview animation?

It is a real, encoded video file. The renderer records actual frames and audio and hands you a playable file you can download, upload to a video platform, or drop into an editor.

What is the maximum video length?

Projects can target up to 60 minutes. Long projects are split into short scenes that are generated independently, so nothing depends on one enormous request that could time out.

Do I need my own API keys?

The generation stages call server-side providers configured with VIDEO_GENERATION_API_KEY, IMAGE_GENERATION_API_KEY and TTS_API_KEY. If a key is missing the tool says so plainly instead of pretending generation succeeded.

Can I edit the scenes before rendering?

Yes. Every scene lets you rewrite the narration, change the visual prompt and background, adjust the duration and transition, reorder, duplicate, delete or regenerate it — and the estimated total duration updates as you edit.

What happens if one scene fails?

Only that scene is marked failed with the real provider error. Completed scenes are kept and you can retry a single scene or every failed scene without restarting the project.

How do I keep a cartoon character consistent between scenes?

Fill in the character/style description field. It is injected into the planner and into every scene's image prompt, so the same character traits, outfit and art direction are restated on each generation.

Which resolutions and aspect ratios are supported?

16:9 at 720p (1280×720) or 1080p (1920×1080), which are the standard formats for YouTube, Rumble and embedded WordPress players.

Are subtitles included?

Yes. When subtitles are enabled the narration is split into timed cues and burned into the frames, so captions survive re-uploads to any platform.

Where are my projects stored?

Projects, scene text and generated media are stored locally in your browser's IndexedDB — not in localStorage and not on a server — so large media never bloats the page and nothing is shared.

What the AI Text to Video Generator does

A complete text-to-video pipeline: paste a script or brief, get an editable scene plan, generate a visual and an AI voice-over for every scene, then render a real narrated 16:9 video with burned-in subtitles and download it as a finished file. Placeholder text is one of those small productivity wins that adds up. Instead of typing 'asdfasdf' or copying a Wikipedia paragraph, use the AI Text to Video Generator to drop realistic-looking content into your prototype in one click.

The generator is deterministic in its structure but random in its content, so every result looks natural without being predictable. That matters when you're testing UI layouts, presenting mockups to clients, or building fixtures for automated tests.

Why the AI Text to Video Generator is useful

Because the AI Text to Video Generator runs locally there is no rate limit, no signup and no waiting. Regenerate as many times as you need until the length and shape of the output fit your design.

Pair the AI Text to Video Generator with the Text Case Converter to match the tone of your mockup (Title Case for headlines, sentence case for body copy), and with the Remove Extra Spaces tool if you're pasting the output into a picky editor. The tools compose into a fast, browser-only content workflow.

Also known as: ai text to video generator, text to video, script to video, cartoon story video generator, tutorial video generator, ai video maker, free ai text to video generator.

Control the length and format with a single input value

Real-life use cases

Design mockups and prototypes

Realistic placeholder text shows a client how a layout breathes far better than repeated lorem ipsum blocks or a row of dummy characters.

Test fixtures

Automated tests need predictable input of a known length. Generating it here saves writing a helper for a one-off case.

Documentation and demos

Sample content makes examples and screenshots readable without exposing any real customer data.

Tips for the best results

Generate slightly more content than you need, then trim to fit your layout.
Match the generated length to real content so your mockup reflects reality.
Regenerate a few times to avoid a repeated pattern in side-by-side screenshots.
