Why we like it

Ferret Marker stands out in the aescripts library for offering two distinct sampling methods, letting you match the search to linear or eased, expression-driven animation.

What is Ferret Marker?

Ferret Marker is a timeline tool for After Effects that searches for a value you specify and places markers wherever that value occurs. You enter the value you want to identify in a target value editbox, and the tool locates its instances across the timeline.

Two sampling methods are available through a dropdown list. Linear Interpolation is described as a generic and stable research method, while Cubic Spline Interpolation is an accurate research method for smooth animations set with expressions and keyframes with Easy Ease. Choosing between them lets you match the analysis to the type of animation you are working with.

Released in December 2023 as version 1.0, Ferret Marker supports a broad range of After Effects releases, from CS3 through the 2026 version. It is listed here as free, with the developer inviting an optional tip. A demo video is available for anyone who wants to see it before installing.

Who is Ferret Marker best for?

Ferret Marker is best for after Effects users who need to find where a specific value occurs across the timeline and mark those points.

How much does Ferret Marker cost?

Ferret Marker is completely free to download and use.

Frequently asked questions

What After Effects versions does Ferret Marker support?

Ferret Marker supports a wide range of After Effects releases. Compatibility spans the 2026, 2025, 2024, 2023, 2022, 2021 and 2020 versions, as well as CC 2019, CC 2018, CC 2017, CC 2015.3, CC 2015, CC 2014, CC, CS6, CS5.5, CS5, CS4 and CS3. This makes it usable across both current subscription releases and much older Creative Suite installations, so most existing After Effects setups should be covered.

What is the difference between the two sampling methods in Ferret Marker?

Ferret Marker lets you choose between two timeline analysis methods from a dropdown list. Linear Interpolation is described as a generic and stable research method. Cubic Spline Interpolation is described as an accurate research method for smooth animations that are set with expressions and keyframes using Easy Ease. Selecting the appropriate method lets you match the analysis to the kind of animation on your timeline before Ferret Marker locates the target value and adds markers.

Is Ferret Marker free to use?

Ferret Marker is listed here as free. The developer also invites an optional tip if you want to support the work, but a payment is not required to use the tool. For the most current licensing details, check the developer's page. The plugin has been available since its version 1.0 initial release in December 2023, so you can confirm the latest terms there before downloading.
