Overview

Matte finishing for ANY alpha — a keyer's, a roto's, an imported matte, or one Crucible made. Clean the haze out of black and white, feather or sharpen, tighten contrast, shift the edge, grow or erode just the solid core. Shift Edge is the one to know: it translates the soft profile along its own gradient instead of eroding, so nudging a feathered edge keeps the falloff you spent time on. Every knob is a no-op at its default.

How to

How-to

Wire any alpha — a keyer's, a roto's, a Crucible's — and pick matte.
clean_black / clean_white clear the haze; feather or contrast reshape the edge; shift_edge moves it in or out.
core_grow fills pinholes without fattening the edge.

Parameters

Parameter	Type	Default	What it does
matte	Choice	alpha	What to refine: the input's own `alpha`, or the `crucible` matte layer the engine wrote. `alphacrucible`
feather	Float	0.0	Softens the edge outward/inward by this many pixels.
contrast	Float	0.0	Steepens (>1) or flattens (<1) the response around the pivot.
shift_edge	Float	0.0	Move the half-alpha line in or out by this many pixels without changing its softness — a matte that is a touch fat or thin.
clean_black	Float	0.0	Alpha at or below this goes to 0 — takes the near-misses out of the background.
clean_white	Float	0.0	Alpha at or above this goes to 1 — solidifies the core.
core_grow	Float	0.0	Grow the solid core by this many pixels while the soft edge keeps its width — fills pinholes without fattening the edge.
disabled	Bool	false	Bypass: the node passes its first input through untouched (D in the graph). The knobs keep their values for when it comes back.
label	Text		A note shown under the node in the graph — what this node is FOR. Never affects the render or the cache.
hide_input	Bool	false	Draw the node without its input wire — a tidy graph for a node whose source is obvious (a Dot, a viewer tap).
