MaskMotion is an After Effects tool that brings masks to life, letting a mask shape move, grow and change across a composition. Masks are often used to hide or reveal parts of a layer, and MaskMotion makes that motion easy to shape with clear controls instead of a long list of manual keyframes. It suits title reveals, wipe transitions and product highlights where the visible area needs to travel with purpose. Updated Aug 21, 2026.

Key Features

• Animates mask shapes across a composition with smooth motion
• Creates reveals, wipes and travelling highlights from masks
• Clear controls that reduce the need for manual keyframes
• Works with masks on footage, shapes and text layers
• Keeps the mask editable so you can refine the result later

How to Download

1. Open After Effects on your Mac and save your current project first.
2. Install the tool through the aescripts manager or copy it into the Scripts folder, then restart After Effects.
3. Draw a mask on a layer, open the MaskMotion panel and choose the motion you want.
4. Preview the animation, adjust the timing and render when it looks right.

System Requirements

MaskMotion needs a Mac with a recent version of macOS and a supported version of Adobe After Effects. It runs inside After Effects as a script, so it shares the memory and processor of your Mac with your project. Larger compositions benefit from a faster Mac.

FAQs

Do I need to know expressions to use MaskMotion?

No, the tool uses simple panel controls, so you can shape mask motion without writing expressions.

Can I still edit the mask after animating it?

Yes, the mask stays editable in your composition, so you can change its shape or timing at any point in the project.
