Introduction to Manipulating
andCombining Keys
Each node’s key input and key output makes it possible to route key channel data from one
node to another so you can apply isolated corrections. Furthermore, the Key Mixer lets you
combine a variety of keys from different nodes to create more detailed keys with which to
tackle complex operations. This section covers all the ways you can recombine key data, as
well as how keys can be used in conjunction with the Alpha output to create regions of
transparency in a clip for compositing right within DaVinci Resolve.
Outside Nodes
Whenever you use a Power Window or HSL Qualifier to limit a correction within one node, a
special node structure lets you automatically create a second node, called an Outside node, to
apply additional adjustments to the inverse of the region you isolated in the previous node.
Outside nodes are really just Corrector nodes with the Key Palette’s Key Input Invert control
enabled, which makes it easy to apply separate corrections to an isolated subject and to its
surroundings.
The Key Input Invert button, in the
Key palette, that inverts any key fed
to that node’s Key Input
In the following example, the sky has been isolated using a Power Window, and an Outside
node has been added to make an additional correction to everything else within the shot.
The Outside node automatically has
its key input inverted
To add an Outside node to a node, creating a secondary correction:
1 Select a node that has been limited using a Power Window or HSL Qualifier.
2 Do one of the following:
Choose Nodes > Add Outside (Option-O).
Right-click a node choose Add Outside Node.
Press the ADD OUTSIDE button on the T-bar panel of the DaVinci control panel.
A new node is created immediately after the selected node, with the RGB and key
outputs of the first node automatically connected to those of the new node.
