Why we like it

True Comp Duplicator earns its place in the aescripts library as one of the more popular scripts there, offering hierarchy-aware duplication with fine control over depth, filtering and naming.

What is True Comp Duplicator?

True Comp Duplicator, developed by Brennan Chapman, creates a complete duplicate of selected comp hierarchies in After Effects, including their subcomps. It offers many options for controlling the process, from setting a depth limit to duplicating footage items alongside the comps.

The script updates expressions in the duplicated comps and can produce multiple copies in one pass. An include/exclude filter, now with a regex option, controls which items are duplicated, and you can duplicate multiple comps at once. Improved naming, an updated GUI and built-in help round out the toolset.

It is one of the more popular scripts on aescripts and is CS6+ compatible, with support spanning releases from CS3 through After Effects 2026. Version 3.9.14 was last updated in October 2020, with a fix for global memory space issues. A demo video is available.

Does True Comp Duplicator update expressions in duplicated comps?

True Comp Duplicator updates expressions in the comps it duplicates, so references carry over to the new copies. Beyond expressions, it can also duplicate footage items, produce multiple copies in a single pass and apply a depth limit that controls how far down the hierarchy it goes. An include/exclude filter, now with a regex option, lets you decide which items are duplicated in each run.

Can True Comp Duplicator duplicate more than one comp at a time?

True Comp Duplicator can duplicate multiple comps at once, and it can also create multiple copies of a selection. It duplicates complete comp hierarchies, including subcomps, and improved naming helps keep the resulting copies organized. A depth limit and an include/exclude filter give further control over exactly what gets duplicated, and built-in help is available within the script for reference.
