Hybrid Erode
This slider dilates or erodes the Hybrid matte. You can view the results by selecting Hybrid
matte in the View Mode menu.
Adjust Lighting
Before applying the Adjust Lighting operation, it is necessary to determine the backing screen
color using Auto Compute or Select Background Color. After performing one of those
operations, click on the Adjust Lighting button. Primatte generates an artificial clean plate and
uses it to generate an evenly lit backing screen behind the foreground object. The default
setting should detect all the areas that contain foreground pixels and deliver a smooth backing
screen for the keying.
Lighting Threshold
Should Adjust Lighting fail to produce a smoother backing screen, adjust the Lighting Threshold
slider while viewing the Lighting Background setting in the View Mode menu. This displays the
optimized artificial backing screen that the Adjust Lighting mode creates.
Crop
This button reveals the Crop sliders to create a rectangular garbage matte with the Primatte
node. As opposed to Fusion’s Cop tool, this does not change the actual image size.
Reset
Resets all the Primatte key control data back to a blue- or green-screen.
Soft Reset
Resets just the Primatte parameters used since the Select Background Color operation was last
completed.
Fine Tuning Tab
The Fine Tuning tab can make refined adjustments to the spill suppression, density of the
matte, and semitransparent areas. These sliders provide a bit more granularity over the Spill(+)
(-), Matte(+)(-) and Detail(+)(-) buttons in the Primatte tab.
