What’s new in Keystone 3?

Already familiar with Keystone?
Here’s a summary of what’s new in this major release.

Keyframe Values 

Add, multiply, round… Works on all selected keyframes.

Layer Order 

Keep your layers organized with a wide range of sorting methods.

Section shortcuts 

Toggle sections on and off only when you need them.
💡 CTRL/⌘ + click to close them all

New Stagger options 

A Bezier controller to bring life to your staggers, along with three options for even easier use.
💡 ALT + click to activate the cumulative mode

Simple. Clear. Customizable.

Keystone’s interface is built for speed and simplicity, with most actions just one click away. The new section shortcuts let you show or hide sections instantly, so you can keep your screen uncluttered and focused on your work.

Save a LOT of time

Manipulating keyframes and layers takes a lot of time when done natively in After Effects. By using Keystone just a few times a day, you will easily save several minutes per day, an hour per week, and several hours per month.
The more keyframes and layers you use, the more time Keystone saves you!

Complete overhaul of the Stagger and Distribute functions

Staggering is one of the most widely used techniques in motion design.
With the new Bezier controllers of Keystone 3, say goodbye to boring linear staggers and distributions and take your animations to the next level. On top of that, 3 new modes make it more intuitive than ever.

Other tools can’t. Keystone can.

After Effects is notoriously known for breaking easings when you move keyframes, and other third-party tools on the market don’t do any better.
Keystone is the only tool that performs the necessary calculations to preserve your carefully crafted motion curves.

Align your tangents and keep them aligned effortlessly

A user favorite since Keystone 1, the “Constant Speed” feature takes away the struggle of aligning tangents by hand. Best of all, these constant speeds are preserved when using any other Keystone 3 function.

Link / unlink keyframes and layers

The “Link” options are arguably the most underrated feature of Keystone 3! They unlock a whole new level of keyframe and layer manipulation, enabling you to link or unlink them in ways that are impossible natively in After Effects.

Up to 3 modes per function

Easily accessible with shared hotkeys, modes let you control how keyframes or layers are grouped together.

Below is an example using the “Align to CTI” function:
