Template Structure

Rendervid templates are JSON objects with three main sections:

{
  "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"
            },

              }
            ]
          }
        ]
      }
    ]
  }
}

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

Best Practices

Template Design

1. Keep it Simple

   • Start with examples
   • Build complexity gradually
   • Test frequently

2. Use Dynamic Inputs

   • Make values customizable
   • Provide sensible defaults
   • Document input purposes

3. Optimize Frame Ranges

   • Minimize total frames for faster rendering
   • Use appropriate FPS (24-30 for most content)
   • Consider file size vs quality tradeoffs

4. Test Animations

   • Preview before full render
   • Check timing and easing
   • Verify layer stacking

Performance

1. Draft Quality for Iteration

   • Use draft quality during development
   • Switch to high quality for finals
   • Consider file size requirements

2. Batch Rendering

   • Reuse templates when possible
   • Queue multiple renders
   • Monitor resource usage

3. Asset Optimization

   • Compress images before use
   • Use appropriate video codecs
   • Optimize Lottie animations

AI Integration

1. Clear Descriptions

   • Describe intent clearly
   • Specify dimensions and duration
   • Mention animation preferences

2. Validate Templates

   • Always validate AI-generated templates
   • Check for common errors
   • Test with sample data

3. Iterate Progressively

   • Start simple, add complexity
   • Test each change
   • Use examples as starting points

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
