 Zoom control: This control lets you zoom in and out on the duration displayed by the
ruler in the keyframe graph area, expanding and contracting the keyframe graph
ruler as you do so. This also keeps the area of the visible keyframe graph centered as
you zoom in or out. For more information, see “
Zooming In to the Keyframe Graph ”
on page 261.
 Zoom slider: This slider lets you zoom in and out of the duration displayed by the
keyframe graph ruler by dragging the thumb tabs on either side, adjusting both
thumb tabs and leaving the visible area of the keyframe graph centered. Pressing the
Shift key and dragging one of the thumb tabs zooms in or out of the keyframe
graph, locking the opposite thumb tab and moving the visible area of the keyframe
graph in the direction in which you’re dragging. For more information, see “
Zooming
In to the Keyframe Graph ” on page 261.
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 and Color Corrector 3-Way Filters ” on page 439
and “ Overview of Compositing Using the Chroma Keyer Filter ” on page 391.
Note: All the controls described here are also available when you use FXScript to create
custom filters. For more information, see the separate PDF document, Using FXScript,
available from the Help menu.
