Free Verified Download | Un Precompose After Effects Plugin

Pre-composing, or "pre-comping," is one of the most fundamental and useful features in Adobe After Effects. It allows you to take a group of layers, nest them into a new composition, and clean up your timeline. But what happens when you need to reverse the process—when you need to pull all those layers back out of the pre-comp and into your main composition? After Effects, despite its power, has no native "un-precompose" button. For years, editors, motion designers, and VFX artists have been stuck manually copying and pasting elements, re-applying effects, and realigning keyframes just to undo a simple organizational decision.

After installation, if you don't see Un-Precompose under the menu, double-check that you placed the plugin file in the correct directory. Also, ensure that you have selected a pre-comp layer in your timeline. The menu option is disabled and grayed out if no pre-comp is selected.

The Professional Alternative: Un-Precompose (via aescripts + aeplugins)

Adobe After Effects relies heavily on pre-compositions to keep complex timelines organized. However, nesting layers inside a pre-comp is often a one-way street. Once you pre-compose a group of layers, Adobe does not provide a native, single-click "un-precompose" button to extract them back into your main timeline while preserving keyframes, effects, and tracking data.
