How to use Keying node in Oraphim

Type ID: fusion.chromakeyer
Category: Keying

What this node does

The Keying node is registered in Oraphim's Keying category and performs the graph operation represented by its sockets and controls below.

The current Oraphim runtime registers 0 sockets and 61 properties for this node. Its main registered inputs are no fixed inputs; its main outputs are no fixed outputs. The tables below are generated from the runtime registry rather than a handwritten approximation.

Inputs

This node has no fixed input sockets in the current runtime registry.

Outputs

This node has no fixed output sockets in the current runtime registry.

How to use it

1. Add Keying from node search. Use fusion.chromakeyer when you need the exact registry entry.
2. Place the node as a source/context operation; it has no fixed input socket in the current registry.
3. Start with the registry defaults and adjust Keying Effect, View, Quality first so you can see the node's effect in isolation.
4. Because there is no fixed output socket, validate the graph context or downstream resource that this node is intended to affect.
5. Preview a representative frame, change one input/control at a time, and save/reopen reusable graphs to verify persistence.

Practical example

Create a small test graph with Keying. Change Keying Effect away from its registry default and compare the result. Keeping this test graph small makes socket-type, context, and parameter mistakes easier to diagnose before the node is used in a production graph.

Troubleshooting

• If a connection is rejected, compare the exact socket data types in the tables above; Oraphim graph connections are typed.
• If the result looks unchanged, confirm this node is on the active path to the viewer/output and that the expected graph/resource is selected.
• If a control is unavailable, check required inputs and whether the property belongs to an internal or mode-dependent group.
• If a saved graph behaves differently later, reopen it and verify node identity, connections, and edited property values before rendering.
