Key Inputs and Outputs:
The gray triangles at the bottom right and left of each node are used to route the
key channel generated by a node’s Qualifier or Window controls, or imported via a
Matte clip that you previously associated with a clip in the Browse page. When you
connect the Key output of one node to the Key input of another, you basically copy
the first node’s key to the second node. You can also combine the Key outputs of
multiple nodes in various ways using the Key Mixer node.
The Output:
The RGB output of the last node in a tree must be connected to the Output bar,
which “completes the circuit” of image processing, and passes that correction on to
the next stage in the DaVinci Resolve image processing pipeline. If the output is not
connected, the node tree has no effect on the clip. You can only connect one RGB
output at a time to the Output bar.
Nodes are connected to one another by “connection lines,” with a small arrow bisecting each line that
indicates the direction in which image or key data is flowing.
To connect two disconnected nodes:
• Click-and-drag from the RGB or Key output of one node to the corresponding
RGB or Key input of another, and when the dotted line turns solid, release the
mouse button.
To disconnect two nodes:
• Click a link to select it (selected links turn yellow), and then press the Forward-
Delete key.
• Right-click a link and choose Delete Link.
You can connect any node’s RGB or Key output to as many inputs as you want, but you can only have
one connection going to a node’s input (although some nodes have multiple inputs for combining
multiple nodes, including the Parallel, Mixer, and Key Mixer nodes).
