Adjusting Spill Controls with the Colour Curves Node
After you create a key and key out any trouble areas, some of the background colour may have spilled over
at the edge of the key. Colour spill suppression in the component keyers is done through the Colour Curves
node. The Colour Curves menu lets you sample the colour you want to suppress and then suppress that
colour where necessary, using the suppression curve.
Adjust the Suppression curve in the Colour Curves node to suppress a selected colour.
Adjust the Hue Shift curve in the Colour Curves node to perform a hue shift on a selected colour.
NOTE To remove colour spill in the Master Keyer, see Basic Colour Spill Removal (page 688) and Advanced Colour
Spill Removal
(page 689). Alternatively, you can connect a Colour Curves node between the front clip and the front
input of the Master Keyer and follow the procedures below.
Adjusting the Suppression Curve
To suppress colour spill using the suppression curve:
1 Set the view to Result, so that you can see the changes as you make them.
2 Double-click the Colour Curves node in the schematic.
The Colour menu appears.
