Lock Color Picking
When this checkbox is activated, it prevents the accidental growth of the selected range by
selecting more colors from the view. It is a good idea to activate this checkbox after selecting
the color for the matte. All other controls in the node remain editable.
Reset Pre Matte Ranges
This button discards all color selection by resetting the ranges but maintains all other slider and
control values.
Matte Tab
The Matte tab refines the Alpha of the key, combined with any solid and garbage masks
connected to the node. When using the matte tab, set the viewer to display the Alpha channel
of the Delta Keyer’s final output.
Threshold
This range slider sets the lower threshold using the handle on the left and sets the upper
threshold using the handle on the right.
Any value below the lower threshold setting becomes black or transparent in the matte.
Any value above the upper threshold setting becomes white or opaque in the matte. All values
within the range maintain their relative transparency values.
Restore Fringe
This restores the edge of the matte around the keyed subject. Often when keying, clipping
occurs around the edge of the subject where there is hair. Restore Fringe brings back that edge
while keeping the matte solid.
