Once gradient transparency and offset have been determined, the degree of smoothness can be set using
the Inner Edge and Outer Edge fields. You can then use the Distance field to determine the area where Inner
Edge and Outer Edge settings have an effect.
To apply uniform softness:
1 Access the Garbage Mask menu.
2 Select a mask in the image window.
3 If necessary, toggle the Edge Softness box to Softness.
4 Set the border of the softness gradient using the Offset field. The gradient will be affected by how far
the softness border is offset from the edge of the mask.
5 Set the transparency of the gradient using the Alpha field.
6 Use the Inner Edge field to smoothen the softness gradient towards the inside.
7 Use the Outer Edge field to smoothen the softness gradient towards the outside. Adjusting this value
is especially noticeable if you are smoothening a transition from a black inside edge to a white outside
edge.
8 Use the Distance field to modify the area of which the Inner and Outer Edge adjustments have an
effect.
Applying Softness Using Pickers
You can change the default mode of the Tracer from advanced gradient to pickers, allowing you to sample
colours inside and outside the garbage mask spline, to apply softness according to the colour transition in
the clip. Individual vertices can be set to either of these modes.
When great control over the mask edge is needed, for example, for fine edge detail, use pickers to effectively
key out the background. The Tracer uses pairs of pickers to do luma and chroma analysis of the area inside
and outside of the mask and derives localized edge keys from this information.
