## Template Structure

Rendervid templates are JSON objects with three main sections:

```json
{
  "name": "My Video",
  "output": {
    "type": "video",
    "width": 1920,
    "height": 1080,
    "fps": 30,
    "duration": 5
  },
  "inputs": [
    {
      "key": "title",
      "type": "string",
      "label": "Title",
      "default": "Hello"
    }
  ],
  "composition": {
    "scenes": [
      {
        "id": "main",
        "startFrame": 0,
        "endFrame": 150,
        "backgroundColor": "#1a1a2e",
        "layers": [
          {
            "id": "title",
            "type": "text",
            "position": { "x": 960, "y": 540 },
            "size": { "width": 1600, "height": 200 },
            "inputKey": "title",
            "props": {
              "fontSize": 120,
              "color": "#ffffff",
              "textAlign": "center"
            },
            "animations": [
              {
                "type": "entrance",
                "effect": "fadeInUp",
                "duration": 30,
                "easing": "easeOut"
              }
            ]
          }
        ]
      }
    ]
  }
}
```

### Key Concepts

**Output Configuration:**
- Defines video/image dimensions, FPS, duration
- Supports multiple formats and codecs

**Dynamic Inputs:**
- Variables that can be customized per render
- Support strings, numbers, booleans, colors, images, videos

**Composition:**
- Scenes with frame ranges
- Layers with types, positions, props
- Animations with presets and easing

## Common Patterns

### Pattern 1: Text Animation
```
User: "Create a video with animated text"

AI flow:
1. get_capabilities() to understand animations
2. render_video() with fadeIn animation
```

### Pattern 2: Social Media Content
```
User: "Make an Instagram story for a product launch"

AI flow:
1. list_examples({ category: "social-media" })
2. get_example({ examplePath: "social-media/instagram-story" })
3. render_video() with custom inputs
```

### Pattern 3: Data Visualization
```
User: "Create an animated bar chart showing Q1 sales"

AI flow:
1. get_example({ examplePath: "data-visualization/animated-bar-chart" })
2. Modify template with data
3. render_video()
```

### Pattern 4: Batch Generation
```
User: "Create 10 videos with different titles"

AI flow:
1. Load template once
2. Call render_video() 10 times with different inputs
```

### Pattern 5: Template Validation
```
User: "Check if my custom template is valid"

AI flow:
1. validate_template() to check structure
2. Fix any errors
3. render_video() to generate
```

## Example Workflows

### Workflow 1: Quick Social Media Post

```
User: "Create an Instagram story announcing a flash sale"

AI Agent:
1. list_examples({ category: "social-media" })
2. get_example({ examplePath: "social-media/instagram-story" })
3. render_video({
     template: {...},
     inputs: {
       title: "Flash Sale",
       subtitle: "50% Off Everything",
       backgroundColor: "#FF6B6B"
     },
     format: "mp4",
     quality: "high"
   })

Result: Instagram-ready 1080x1920 video
```

### Workflow 2: Data Visualization

```
User: "Create an animated chart showing Q1 revenue growth"

AI Agent:
1. get_example({ examplePath: "data-visualization/animated-bar-chart" })
2. Modify template with revenue data
3. validate_template({ template })
4. render_video({
     template,
     inputs: { data: [...], title: "Q1 Revenue" },
     format: "mp4",
     quality: "high"
   })

Result: Animated bar chart video
```

### Workflow 3: Custom Template Creation

```
User: "Create a custom video with my brand colors and logo"

AI Agent:
1. get_capabilities() to understand options
2. Start with example template
3. Customize colors, fonts, layout
4. validate_template() to check
5. render_video() with draft quality
6. Iterate based on preview
7. Final render with high quality

Result: Custom branded video
```

### Workflow 4: Batch Video Generation

```
User: "Create welcome videos for 100 new users"

AI Agent:
1. get_example({ examplePath: "business/team-introduction" })
2. Loop through user list:
   - render_video({
       template,
       inputs: { name: user.name },
       outputPath: `welcome-${user.id}.mp4`
     })

Result: 100 personalized welcome videos
```

## Troubleshooting

### Common Issues

**Issue: Server not connecting**
- Check absolute path in MCP config
- Verify Node.js version (20+)

- Review logs in AI editor

**Issue: FFmpeg not found**
```bash
# Install FFmpeg
brew install ffmpeg  # macOS
sudo apt install ffmpeg  # Ubuntu
choco install ffmpeg  # Windows
```

**Issue: Template validation fails**
- Check JSON syntax
- Verify required fields
- Review error messages
- Use validate_template tool

**Issue: Slow rendering**
- Use draft quality for iteration
- Reduce video duration/FPS
- Optimize asset sizes
- Check system resources

**Issue: Node version errors**
- Update to Node.js 20+
- Use full Node.js path in config
- Verify with: `node --version`
