Parameters
| Parameter | Type | Default | What it does |
|---|---|---|---|
| screen | Choice | green | The screen colour to key: green or blue. greenblue |
| threshold | Float | 0.1 | How different from the screen colour a pixel may be and still count as screen. |
| passes | Int | 24 | Smoothing passes over the screen estimate. More is flatter and slower. |
| 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). |
