A focused single-purpose script that earns its place for handling aspect-ratio flipping across single or multiple comps at once.
Flip Aspect Ratio is a script for After Effects that swaps a composition's width and height. Select one or more compositions, either by clicking in the timeline or selecting multiple comps in the project panel, then click the Flip button to flip the width and height.
A Settings panel lets you change the scaling method and choose whether to fit the old comp to the new comp's width or height. This gives you control over how existing content adapts once the aspect ratio has been flipped.
The script has been tested on After Effects CS6 and later, with listed compatibility spanning versions from CS6 through After Effects 2025. It was released in September 2023 as version 1.0. A demo video is available for those who want to see it before adding it to their workflow.
Flip Aspect Ratio is best for after Effects users who need to swap composition width and height quickly.
Flip Aspect Ratio is completely free to download and use.
Flip Aspect Ratio lists compatibility with a wide range of After Effects versions, from CS6 through CC 2014, CC 2015, CC 2015.3, CC 2017, CC 2018, CC 2019, and the 2020, 2021, 2022, 2023, 2024 and 2025 releases. The developer notes the script has been tested on After Effects CS6 and later, so it covers both older and current versions of the application across a long span of releases.
Flip Aspect Ratio works by first selecting the composition or compositions you want to change. You can do this by clicking in the timeline or by selecting multiple comps in the project panel. Once selected, click the Flip button to swap the width and height. The Settings panel adds further control, letting you change the scaling method and decide whether to fit the old comp to the new comp's width or height.
Flip Aspect Ratio is listed as free in this catalog. Licensing terms can change over time, so for the current details and any conditions attached to using the script, check the developer's page before you download. The listing here reflects version 1.0, released in September 2023, and pointing to the official page is the most reliable way to confirm how the script is distributed.
