after-effects

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.

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.

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.

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.

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.

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.
