Using the Key Palette to Adjust Key Mixer Controls
When you open the Key palette for a selected Key Mixer node, you can adjust the
following controls:
Key palette showing controls when a Key Mixer is selected
 Input list: A list of every input that’s connected to the Key Mixer. Each entry on the list
has the following controls:
–
Input name: The name of each node connection attached to that key mixer, such as
Input Link 1, Input Link 2, and so on.
–
Input invert: Inverts the key being fed into this particular input. Off by default.
–
Input mask: Lets you switch the key input between Matte and Mask modes. In Matte
mode (on) the key input combines via intersection with other inputs connected to
the Key mixer. In Mask mode (off by default), the key input is added to the other key
inputs connected to the Key mixer.
–
Gain parameter: Decreases or increases the intensity of that input matte’s
contribution to the resulting output matte.
–
Offset parameter: Adjusts the contrast of that input matte’s contribution to the
resulting output matte.
 Output invert: Inverts the overall result of the various Input Link interactions.
 Gain: This parameter increases or reduces the strength of the resulting output key.
Setting Gain to 0 results in all inputs being set to black, while the default setting of 1.00
outputs the combined mattes at full strength. The maximum setting of 2.00 increases
the intensity of any part of the key output that’s less than 100 percent white, which
can have the practical effect of “growing” soft edges. You can also use this parameter
to keyframe the key output to fade that node’s contribution in or out with one set of
keyframes.
 Offset: Lets you adjust the contrast of the Output key.
