# Video

```gistui
root = Video("https://www.youtube.com/watch?v=aqz-KE-bpKQ", title:"Big Buck Bunny (sample)")
```

## Signature

This is the line a model reads in the system prompt.

```gistui
Video(src, title:str, poster:str, ratio:str)
```

- **Group:** Content
- **Children:** No
- **Positional arguments:** `src` (a trailing `?` means it may be left out)

## Props

| Prop | Type | How to write it | Notes |
|---|---|---|---|
| `src` | string (URL) | positional, required |  |
| `title` | string | named: `title:…` |  |
| `poster` | string (URL) | named: `poster:…` |  |
| `ratio` | string | named: `ratio:…` |  |

## Use your own component

Keep the name and schema, swap what is drawn. The prompt and the model's output do not change.
