Aescripts – MaskMotion

Aescripts – MaskMotion

🥳 Orginal Version / Lasted Version / Activation Code

MaskMotion is a native C++ After Effects plugin that lets you animate masked regions independently from a single layer.

Assign your masks to regions, then animate Position, Anchor, Scale, Rotation, and Opacity, without duplicating layers or cluttering your timeline.

8 Independent Regions

Up to 8 regions per effect instance, each mapped to one of your layer’s existing masks.

Automatic Mask Detection

Region dropdowns update automatically to match your mask names — no manual wiring.

Full Keyframe Support

Animate Position, Anchor, Scale, Rotation, and Opacity on every region with standard AE keyframes.

8 / 16 / 32-bit Color

Supports all After Effects color depths for maximum flexibility in high-end pipelines.

Multi-Frame Rendering

Fully MFR-compatible. No performance bottlenecks when AE parallelizes your render.

Smart Render Support

Uses pre-render data for stable, correct output. Parameters checked via AE checkout APIs.
