文档

After Effects MCP Bridge

This skill enables programmatic control of Adobe After Effects via ExtendScript (.jsx) automation and command-line tools.

🛠️ Core Capabilities

1. ExtendScript Automation

Use scripts/ae_script.jsx to execute After Effects operations:

  • Create/modify compositions
  • Add layers, effects, keyframes
  • Batch render projects
  • Manipulate project structure

2. Command-Line Rendering

Use aerender (After Effects command-line renderer) for:

  • Headless rendering
  • Batch processing
  • Queue management

3. Project Template System

Use assets/templates/ for reusable AE project templates.

📋 Usage Patterns

Pattern 1: Create Composition Programmatically

jsx
// scripts/create_comp.jsx
var comp = app.project.items.addComp("MyComp", 1920, 1080, 1, 30, 300);
var solid = comp.layers.addSolid([1,0,0], "Red Solid", 1920, 1080, 1);

Pattern 2: Batch Render Project

bash
aerender -project ./my_project.aep -output ./output.mov -mp

Pattern 3: Apply Effect via Script

jsx
// scripts/apply_effect.jsx
var layer = app.project.activeItem.selectedLayer(1);
layer.property("ADBE Effect Parade").addProperty("ADBE Gaussian Blur");

🔧 Available Scripts

ScriptPurpose
create_comp.jsxCreate new composition with specified params
batch_render.jsxQueue multiple compositions for render
apply_effect.jsxApply effects to selected layers
export_template.jsxSave project as template (.aet)

🚀 Quick Start Workflow

  1. Check AE Installation: Verify After Effects is installed

    bash
    which aerender

  2. Load Project: Open existing .aep or create new

    jsx
    app.open(new File("./my_project.aep"));

  3. Execute Script: Run ExtendScript via:

    • AE: File → Scripts → Run Script File
    • Command-line: aerender -script ./myscript.jsx

  4. Render Output: Use aerender for headless rendering

⚠️ Requirements

  • Adobe After Effects installed (CC 2019+)
  • ExtendScript Toolkit (optional, for debugging)
  • aerender in PATH for command-line rendering

  • Effect Names: See references/effect_names.md
  • Render Settings: See references/render_settings.md

🎯 Monitoring

Be verbose about:

  • Composition settings (resolution, duration, framerate)
  • Effect choices and parameters
  • Render queue status
  • Output format decisions
