        "duration": "5s"
    }
)
```

## Effective Prompts

### Character-Focused
```
A young woman with brown hair smiles and turns to face the camera,
natural sunlight, shallow depth of field, cinematic, 4K quality
```

### Action Sequences
```
Man running through rain-soaked city streets at night,
neon reflections, dynamic camera following, slow motion moments
```

### Product Shots
```
Sleek smartphone rotating on minimalist white surface,
studio lighting, product photography style, smooth 360 rotation
```

### Nature/Landscape
```
Drone shot ascending over misty mountain forest at sunrise,
golden light rays through trees, cinematic color grading
```

## Image-to-Video

### Best Practices
1. Use high-quality source images
2. Describe the motion you want
3. Keep motion reasonable for the image
4. Specify camera movement separately

### Example
```
Source: [Upload portrait photo]
Prompt: Subtle smile forming, gentle head tilt,
hair moving slightly in breeze, maintain photorealistic quality
```
