Threshold

Overview

What Threshold does

Converts a selected channel into thresholded regions with independent threshold, softness, repeat and inversion controls.

Threshold converts a continuous channel into a controlled pass/fail range. Channel chooses the data being tested; Threshold and Softness define the boundary, while the lock controls keep channel behavior synchronized when the output must remain a clean technical matte.

Repeat and Ping-Pong can turn the threshold into a procedural repeating pattern rather than a simple matte. For transparent sources, use the render and premultiplication options carefully so hard threshold decisions do not leave dirty RGB fringes at semi-transparent edges.

When to use it

Generate mattes from luminance
Isolate bright or dark image regions
Create posterized graphic masks
Build procedural repeating bands
Prepare alpha for matte processing
