Key Input Controls
Input invert: Inverts the key being fed into the key input. Off by default.
Input matte: Lets you switch the key input between Matte and Mask modes. In Matte
mode (on by default) the key input combines via intersection with keys generated
internally using the Qualifier or Windows palette. In Mask mode, the key input is added
to the internal key instead.
Gain: Controls the strength of the key connected to the key input.
Offset: Controls the contrast of the key connected to the key input.
Blur Radius: Blurs the key connected to the key input
Blur H/V Ratio: Alters the horizontal/vertical ratio of the blur that’s being applied to the
key input.
Key Output Controls
Qualifier invert: Inverts the overall key.
Gain: Using the key output, this parameter governs the strength of that node’s
contribution to the overall grade. Setting Gain to 0 results in that node having no effect at
all, while the default setting of 1.00 applies the full strength of any adjustments made with
that node. The maximum setting of 2.00 increases the intensity of any part of the key
output that’s less than 100 percent white. 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. This has no effect if the entire
key is 100 percent white (a solid key).
Qualifier Controls
Qualifier invert: Inverts the key created by that node’s Qualifier palette.
Qualifier matte: Lets you switch the interaction of the keys generated by the Qualifier
and Window palettes between Matte and Mask modes. In Matte mode (the default), the
Qualifier and Windows palettes combine via intersection. In Mask mode, they’re added
together instead.
Gain: Lets you raise or lower the strength of the key generated by the Qualifier palette.
Offset: Lets you adjust the contrast of the key generated by the Qualifier palette.
