Mask & Layer Splitter

An essential panel to simplify mask and layer workflows in After Effects. Split masks into layers, batch rename, precomp and crop, and offset layer timing. Focus on creativity, not busywork.

After Effects CC 2020+

The interface provides clear buttons for common tasks so you can move fast on both simple animations and complex shots. Each tool is designed to be predictable and reversible.

KBar support for custom toolbars and quick actions

Separator

Separate masks from a selected layer into individual layers for easier management. Each mask becomes its own layer so you can animate and order them independently.

Optional modifiers for reference layers:
Shift: Duplicate the selected layer, lock it, and mark it as a reference before splitting.
Shift + Ctrl (Cmd on Mac): Remove the reference layer after splitting.

Rename

Batch rename selected layers by appending a suffix or fully replacing names. Preview changes before applying to keep naming consistent across comps.

Precomp & Crop

Automatically create precomps and crop to content bounds. Perfect for organizing complex shots and keeping your timeline tidy.

Offset Layers

Offset the start times of selected layers in ascending, descending, or random order. Great for staggered entrances, cascades, and organic timing.

KBar Support

Integrate core actions into KBar and trigger them with a click or a shortcut. Keep your favorite tools on a compact, customizable toolbar.

Predictable

Clear actions with sensible defaults that respect existing rigs.

Reversible

Works with AE’s undo stack to keep experiments safe.

Theme-aware

Token-based UI looks great in light and dark modes.

Compatibility: Works with After Effects CC 2020 and later. Built to play nicely with common studio naming standards and layout conventions.
