 Keyframe graph ruler: The keyframe graph ruler corresponds to the duration of the
clip or the location of a clip in a sequence:
 If a clip is opened from the Browser: The keyframe graph ruler shows the duration of
the clip itself. The playhead in the Viewer moves independently of the playhead in
the Timeline or Canvas.
 If a clip is opened from a sequence in the Timeline: The keyframe graph ruler shows
the section of the Timeline that the clip is edited into. The playhead in the Viewer
is locked to the playhead in the Timeline and the Canvas.
 Filter Start and End points: If a filter is applied to part of a clip, filter Start and End
points appear in the clip’s keyframe graph area.
 Section of clip not currently used: The frames of a clip displayed in the Viewer’s Filters
tab that are outside the duration specified by the clip’s In and Out points are darker
gray than the part of the clip in use. This helps you know where to apply keyframes.
 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
 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 “
Using Filter Controls
Each filter has its own graphical (visual) and numeric controls, including sliders, point
and Angle controls, color controls, and clip wells. 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 “
