What problem does it solve?

Automates After Effects workflows via ExtendScript to programmatically manage layers, keyframes, expressions, effects, compositions, assets, and rendering, reducing repetitive scripting.

Core Features & Use Cases

Automates creation, modification, querying, and rendering across After Effects projects.
Wraps mutations in undo groups to ensure safe, reversible edits.
Reads project context and applies domain knowledge rules to generate deterministic ExtendScript actions.

Quick Start

Describe your After Effects task in natural language and the skill will generate and run the corresponding ExtendScript to apply it in your project.

FAQPage Schema

How do I automate After Effects workflows using ExtendScript?▼

You can automate After Effects workflows by generating ExtendScript to programmatically create, modify, query, and render layers, keyframes, and compositions. This approach reduces repetitive scripting by applying domain rules to execute deterministic actions.

Can I batch render multiple After Effects compositions programmatically?▼

Batch rendering in After Effects is supported by executing ExtendScript across single or multiple projects. The automation skill generates scripts to manage assets and trigger renders, handling batches while wrapping mutations in undo groups for safe execution.

How do I safely modify layers and keyframes in After Effects via scripting?▼

Safely modify layers and keyframes by wrapping ExtendScript mutations in undo groups. This ensures all automated edits to effects and compositions are reversible, protecting your project context from unintended permanent changes during script execution.

Does After Effects automation work on macOS to apply expressions and effects?▼

After Effects automation on macOS executes ExtendScript via osascript to apply expressions and effects. It reads your current project context, loads domain knowledge rules, and runs the generated JSX scripts directly within your existing environment.

What is the best way to generate ExtendScript for After Effects tasks?▼

The best way to generate ExtendScript for After Effects tasks is describing your requirements in natural language. The system reads project context, applies domain rules, and outputs deterministic JSX code to automate layer and composition modifications.

Why are my ExtendScript changes not reversible in After Effects?▼

ExtendScript changes may not be reversible if mutations are not wrapped in undo groups. Proper After Effects automation ensures all automated script executions affecting layers and keyframes are encapsulated, allowing safe single-step reverts.
