# Topic to AI Story

> Pick a topic and Crealix writes, narrates and illustrates a complete story video — from 30 seconds to 20 minutes.

The fastest way to a faceless video. You choose a topic and, optionally, a direction; Crealix writes the script, records the narration, plans the scenes and generates an AI image (or clip) for each one, then adds captions, music and sound effects.

**Best for:** history, horror, true crime, kids stories, personal finance, psychology, science and tech explainers — any channel where the story matters more than a face on camera.

![Grid of topics such as Historic Story, Horror Stories and Personal Finance](https://mintcdn.com/crealix/IMW-nFsczZqF7L1x/images/app/v2/creator-topics.jpg?fit=max\&auto=format\&n=IMW-nFsczZqF7L1x\&q=85\&s=7ea78d15fe405951dbc7eae96d91c61c)

Topics are grouped by category: Story, Mystery, Business, Education, Health and Tech

## Step by step

**1. Choose a topic**

The topic tells the AI writer what kind of video to make — its tone, structure and visual language.

| Category | Topics |
| - | - |
| Story | Historic Story, Kids Story, Movie Stories, What If Stories, Timeline Stories, Mythological Tales, Fantasy Adventures, Motivational Stories, Women Empowerment Stories |
| Mystery | Horror Stories, True Crime Stories, Space Mysteries |
| Business & education | Personal Finance, Dark Psychology |
| Health | Health Body Insights |
| Tech & science | AI Innovations, Tech Breakthroughs, Science Experiments |

**2. Add extra detail (optional, but recommended)**

**Extra detail for this topic** narrows the topic down. It doesn't replace it.

| Weak | Strong |
| - | - |
| *Pompeii* | *The day Pompeii was buried, told by a baker who stayed behind* |
| *Saving money* | *Compound interest explained with a lemonade stand* |
| *A haunted house* | *A night-shift nurse hears her name called from an empty ward* |

Leave it empty and Crealix picks a fresh angle on the topic each time — handy for testing, and exactly what [Autopilot](https://docs.crealix.ai/autopilot/overview.md) does for every episode.

**3. Add characters (optional)**

Up to 4 [characters](https://docs.crealix.ai/workspace/characters.md) — the first one is the lead. Use them when the same person (or mascot) must look identical in every scene.

**4. Set format, quality and look**

* **Aspect ratio** — 9:16, 16:9 or 1:1.
* **Duration** — 30–55 s, 1, 2, 3, 5, 10, 15 or 20 minutes.
* **Narration language** — 29 languages.
* **AI image quality** — Basic, Pro or Ultra, plus *Multi-clip first scene* and *Visual continuity*.
* **Visual style**, **voiceover**, **music** and **captions**.

Each of these is explained with screenshots in [Common settings](https://docs.crealix.ai/formats/common-settings.md).

**5. Choose the generation path and create**

**Images first** (cheaper — animate scenes later in the editor) or **Full AI Video** (choose how many scenes to animate and the clip quality). Check the estimate in the bottom bar and click **Create video**.

## What happens after you click Create

1. **Script** — the AI writes a script for your topic, timed to the duration, with a hook in the first seconds and a payoff at the end.
2. **Narration** — the script is recorded with your voice and tuning, and split into scenes.
3. **Scenes** — each scene gets an image prompt in your visual style (and your characters), then the image is generated. With Full AI Video, the chosen scenes are also animated.
4. **Finishing** — captions are timed word by word, music is mixed under the voice, and sound effects are placed on key moments.

Short videos are usually ready in a few minutes. You can close the tab — you'll get a notification, and the project waits in [Videos](https://docs.crealix.ai/workspace/videos-and-folders.md).

## Cost

A 60-second video costs about **10 credits** with Basic images or **15** with Pro. Animating scenes into video adds the clip cost (for example about 11 credits for a 5-second 768p clip with MiniMax H3 Max Turbo). Rendering is free in your browser or charged by length in the cloud. The exact estimate is always shown before you create.

## Tips for better topic videos

* **Be specific in the extra detail.** A person, a place, a moment or a twist beats a general subject every time.
* **Match style to topic.** *Stickman* or *Lego* for light history, *Creepy Cartoon* or *Cinematic* for horror, *Realistic* for true crime.
* **Use Multi-clip first scene for Shorts.** The opening seconds decide whether people stay.
* **Want every word to be yours?** Use [Script to AI Story](https://docs.crealix.ai/formats/script-to-ai-story.md) instead.

> Topic videos make great [Autopilot](https://docs.crealix.ai/autopilot/overview.md) series: every episode is a new story inside the topic, and Autopilot never repeats one.
