Using Filter Controls
Each filter has its own graphical (visual) and numeric controls, including sliders, point
and angle controls, and clip and color controls. Some filters, such as the Color Corrector
3-way and Chroma Keyer, have alternate visual controls that you can use to modify
their effects. The parameters set by visual controls are mirrored in the numeric controls
and vice versa. These filters are discussed in detail in separate chapters. For more
information, see “
The Color Corrector Filter ” on page 837 and “ Overview of
Compositing Using the Chroma Keyer Filter ” on page 810.
