Both the Effect Controls and the Timeline
panels let you adjust the timing and values of keyframes, but each
works in a different way. Whereas the Effect Controls panel displays
all effect properties, keyframes, and interpolation methods at once,
clips in the Timeline panel can show only one effect property at
a time. In the Effect Controls panel, you have complete control
over keyframe values. In the Timeline panel, you have limited control
(for example, you can’t change values that use x, y coordinates,
such as Position), however, you can make keyframe adjustments while
editing without moving to the Effect Controls panel.
The graphs in the Timeline and Effect Controls panels display
the values of each keyframe and the interpolated values between
keyframes. When the graph of an effect property is level, the value
of the property is unchanged between keyframes. When the graph goes
up or down, the value of a property increases or decreases between
keyframes. You can change the interpolation method and adjust Bezier
curves in a graph to affect the speed and smoothness of the property
changes from one keyframe to the next.
If you’ve added keyframes
to a sequence clip, you can view them in the Effect Controls panel.
Any effect containing keyframed properties displays Summary Keyframe
icons
when
the effect is collapsed. Summary keyframes appear across
from the effect’s heading and correspond to all the individual property keyframes
contained in the effect. You cannot manipulate summary keyframes; they
appear for reference only.

If you’ve added keyframes to animate
an effect, you can view them and their properties in the Timeline
panel. For video and audio effects, the Timeline panel can display
the keyframes specific to each clip. For audio effects, the Timeline panel
can also display the keyframes for an entire track. Although each
clip or track can display a different property, only one property’s
keyframes can be displayed at a time within an individual clip or
track.

The
segments connecting keyframes form a graph that indicates changes

keyframes and segments changes the shape of the graph.

- Place the pointer directly over a keyframe to view its
property in a tool tip.
The tool tip displays the keyframe’s location, as well
as the property and options you set for it in the Effect Controls
panel. This information is useful for making precise keyframe placements,
quickly noting the value you’ve set for a keyframe, and quickly
comparing the location and change in value of two or more keyframes.
