How do I install a script in After Effects?

Save the script as a .jsx or .jsxbin file. Place it in Adobe After Effects > Scripts or Scripts > ScriptUI Panels (for UI scripts). Restart After Effects. Run it via File > Scripts or access panels via Window.

What's the difference between scripts and expressions?

Scripts are written in ExtendScript and execute a series of commands (usually once). Expressions are snippets of code applied to layer properties and evaluate every frame dynamically.

Can I use the same scripts in Photoshop or Illustrator?

Not exactly. While all use JavaScript, each Adobe app has its own DOM (Document Object Model). Some concepts overlap, but you’ll need to adjust your code based on the target app.

Can scripting speed up video editing?

Absolutely. It can automate project setup. Rename or organize layers. Render multiple versions with different assets. Create reusable animation presets with dynamic input.
