Why we like it

Ouroboros 2 stands out in the aescripts library for stacking many strokes on a single path and driving them from one set of controls, with random width, opacity, timing and speed built in.

What is Ouroboros 2?

Ouroboros 2 is an After Effects script for creating multiple strokes on one single path. Built by Sander van Dijk and Remco Janssen, it can generate centered Line, Square, Circle and Triangle shapes, then place several strokes along the same path and control them together.

Each stroke can carry a random width, opacity, length and offset, while a single color control drives their color. Stroke width can be maintained when the original path scales. You can trim strokes individually or trim them all using the original stroke, and link the Start and End to that original stroke. Dots can be added at the start and end of each line, and you can change stroke direction, cap, join and the random seed.

Animation options include delaying each stroke over time, randomizing those delays, adding continuous or random speed per stroke, and keyframing the speed of all strokes. Version 2.0.4 runs on After Effects from CC 2015.3 through the 2025 release.

Who is Ouroboros 2 best for?

Frequently asked questions

Does Ouroboros 2 work with After Effects 2025 and CC 2015.3?

Ouroboros 2 lists compatibility with After Effects 2025, 2024, 2023, 2022, 2021, 2020, CC 2019, CC 2018, CC 2017 and CC 2015.3, covering a wide range of releases from CC 2015.3 through the 2025 version. If you're on one of those versions you should be able to run it. For any release outside that list, check the developer's page for the latest compatibility details before installing.

Is Ouroboros 2 free to download?

Ouroboros 2 is listed as free here in the catalog. Because distribution and licensing can change over time, the developer's page is the best place to confirm current terms before you download. The script comes from Sander van Dijk and Remco Janssen, and the same page carries version and update information alongside any licensing notes. Check there if you need the authoritative word on how it's offered today.

How do I open Ouroboros 2 in After Effects?

Ouroboros 2 opens from the File > Scripts menu inside After Effects. The 2.0.4 update fixed an issue where it could not be launched from that menu, along with a crash that occurred when it tried to open its preferences on AE 16.0 and later. If you run into trouble opening it, the developer's page and changelog document these fixes and the versions they apply to.

Can Ouroboros 2 maintain stroke width when the original path scales?

Ouroboros 2 can maintain stroke width when the original path scales, so the strokes keep their set width as the source path changes size. It also lets you set a random stroke width for each stroke, color multiple strokes with a single color control, and set random opacity per stroke. These controls sit alongside its trimming, timing and speed options for shaping how the strokes appear along the path.
