Why we like it

Match Comp Duration earns its place in the aescripts library for a focused job: adjusting durations across selected pre-comps and their nested layers, with options for nested, locked and custom-duration cases.

What is Match Comp Duration?

Match Comp Duration is a script for After Effects that changes the duration of selected pre-comps and layers, together with all their nested layers to the deepest level of the project. It can match the selected items to the current composition duration in a single click, or to the current time indicator duration. A custom duration can also be set, so the selected layers match that value instead of the current comp duration. When it changes the total duration, it does not reposition the layers in time.

Beyond duration matching, it can include all nested pre-composed layers as well as nested locked layers down to the deepest level pre-comp. It can also resize all nested comps to the current comp, using fit, width or height.

Match Comp Duration is compatible with After Effects 2025, 2024, 2023, 2022, 2021, 2020 and CC 2019. The current release, version 1.1.1, dates from May 2025 and fixed an issue where the custom duration was relative to the composition start rather than the layer start, so it now respects the layer's in-point.

Who is Match Comp Duration best for?

Match Comp Duration is best for after Effects artists working with nested pre-comps who need to change durations across layers down to the deepest level.

How much does Match Comp Duration cost?

Match Comp Duration is completely free to download and use.

Frequently asked questions

Which After Effects versions does Match Comp Duration support?

Match Comp Duration is compatible with After Effects 2025, 2024, 2023, 2022, 2021, 2020 and CC 2019. That range covers recent releases through several older versions, so it should fit most current After Effects installations. If you are on a version outside that list, check the developer's page to confirm before installing. The current version is 1.1.1, released in May 2025.

Does Match Comp Duration reposition layers when it changes their duration?

Match Comp Duration changes the total duration of the selected layers but does not reposition them in time. It can set durations by matching the current composition, matching the current time indicator, or applying a custom duration you specify. As of version 1.1.1, the custom duration correctly respects the layer's in-point rather than the composition start, so timing stays relative to where each layer begins.

Can Match Comp Duration set a duration other than the current comp's?

Match Comp Duration includes a Set Custom Duration option. When set, the selected layers match that custom value instead of the current composition duration. It can also match the current time indicator duration if you prefer to work from the playhead. Alongside duration changes, it can include nested pre-composed and locked layers down to the deepest level pre-comp, and resize nested comps to the current comp using fit, width or height.

Is Match Comp Duration free to use?

Match Comp Duration is listed as free in this catalog. Since licensing terms can change over time, check the developer's page on aescripts for the current details before you download or deploy it. That page is also the best place to confirm the latest version and compatibility. The version listed here is 1.1.1, last updated on 28 May 2025, with compatibility spanning After Effects 2025 back to CC 2019.
