Colour field Sets the blend value between the front and back image in the area that the mask is affecting
(that is, either outside or inside the mask). A value of 50% is a 50/50 blend between the front and back clip.
A value of 100% is the front clip. A value of 0% is the back clip.

Opacity field Sets the opacity of the matte in the area affected by the mask (that is, either inside or outside

Lasso Fit field Increase or decrease the number of points in the segments of the mask that are drawn freehand.
See Adjusting the Number of Points in Freehand Segments (page 750).
Edge Softness box Apply a uniform gradient or use an advanced gradient to set different levels of softness
for different parts of the mask edge. In the GMask node in ConnectFX or the Modular Keyer, use the Tracer
to set variable softness around the mask edge using pickers. See
Refining the Mask (page 765).
Alpha field Defines the transparency of the gradient from the edge of the mask.
Offset field Defines the border position of the gradient from the edge of the mask.
Inner Edge, Outer Edge, Distance fields Applies the distance and degree of change between the opaque
and transparent part of the mask edge.
Linear Interp Enable to use linear interpolation of the mask border between keyframes. Disable to use
rounded interpolation.
Constant Shape button Enable to modify the mask's shape without setting keyframes. This forces all
animatable parameters (except the Tracer parameter Sample On) to be set for the whole clip rather than for
