What Is After Effects Scripting Language?


Larry Thompson

After Effects Scripting Language is a powerful tool that allows users to automate and extend the capabilities of Adobe After Effects. With scripting, you can create custom scripts that perform various tasks, manipulate layers and properties, automate repetitive tasks, and much more.

Why Use After Effects Scripting Language?

  • Automation: By using scripting, you can automate repetitive tasks and save time. Instead of manually performing actions on multiple layers or properties, you can write a script to do it for you.
  • Customization: With scripting, you have the freedom to customize After Effects according to your specific needs.

    You can create custom tools, add new functionalities, or modify existing ones.

  • Efficiency: Scripts allow you to streamline your workflow by creating efficient processes. You can combine multiple actions into a single script, reducing the number of manual steps required.

Getting Started with After Effects Scripting Language

If you’re new to scripting in After Effects, don’t worry! It may seem intimidating at first, but with some practice and understanding of the basics, you’ll be able to harness its power. Here are the key concepts to get started:

The ExtendScript Toolkit

The ExtendScript Toolkit (ESTK) is Adobe’s integrated development environment for scripting languages like JavaScript. It provides a code editor with syntax highlighting and debugging capabilities specifically designed for scripting in After Effects.

JavaScript as the Scripting Language

After Effects uses JavaScript as its primary scripting language. If you’re already familiar with JavaScript, learning After Effects scripting will be easier for you.

If not, don’t worry! There are plenty of online resources available to learn JavaScript from scratch.

The DOM (Document Object Model)

The After Effects scripting API provides access to the Document Object Model (DOM) of After Effects. The DOM represents the structure and properties of the project, including compositions, layers, effects, and more. By manipulating the DOM through scripting, you can automate various tasks.

Scripting Examples

Let’s take a look at some common scripting examples:

Creating a New Composition

To create a new composition using scripting, you can use the following code:

var comp = app.project.items.addComp("New Composition", 1920, 1080, 1, 10, 30);

Adding a Solid Layer

To add a solid layer to your composition:

var solidLayer = comp.layers.addSolid([1, 1, 1], "Solid", comp.width, comp.height, comp.pixelAspect);

Changing Opacity of a Layer

To change the opacity of a layer:


Tips for Effective Scripting:

  • Plan your script: Before diving into writing code, plan out what you want to achieve with your script and break it down into smaller steps.
  • Use comments: Comments help in understanding your code. They explain what each section does and make it easier for others (or future you) to understand.
  • Experiment and learn from examples: Don’t be afraid to experiment and explore existing scripts. Learning from examples will give you insights into different techniques and approaches.


After Effects Scripting Language opens up a whole new world of possibilities for automating and customizing your workflow. By harnessing the power of scripting, you can save time, streamline processes, and create unique tools tailored to your needs.
