keyframe.
To select multiple keyframes:
Do one of the following:

With the selection tool or pen tool, Shift-click to select multiple contiguous or
noncontiguous
keyframes.

•
With the pen tool, drag a marquee around the keyframes to select contiguous
keyframes. Shift-drag to add more keyframes to an existing selection.
Specifying keyframe values in the Timeline window
You can use the selection and pen tools to edit keyframes in the Timeline window. You
increase or decrease values by dragging keyframes vertically. When working with
keyframes graphically in the Timeline window, be aware of how the values and units of
specific properties are represented along the vertical axis of the time graph, as in the
following examples:
•
Opacity is measured from 0% at the bottom of the scale to 100% at the top of the scale,
and the center of the graph is 50%.
•
Rotation is measured in rotations and degrees, and the center of the graph represents
no rotation (0°). Clockwise rotation values are above the center, and counterclockwise
values are below the center.
•
Audio balance is measured from –100 to 100, with 0 at the center (neutral balance).
Dragging above the center moves balance toward the left channel and sets a negative
value, and dragging below the center moves balance toward the right channel and sets
a positive value.
To specify the value of an effect property in the Timeline window:
1
Make sure that the video or audio effect you want to animate is applied to the clip. See
“Applying and controlling Standard effects” on page 244.
2
Make sure that the keyframes for the clip or track are visible.
3
In the effect properties pop-up menu that appears after the name of the clip or track,
select the property you want to adjust. (If you can’t see the pop-up menu, try increasing
the magnification of the Timeline window. See “Using the Timeline window” on page 114.)
4
Select the pen tool in the toolbox, and do one of the following:
•
If you want to edit multiple or nonadjacent keyframes, select those keyframes.
•
Position the pen tool over a keyframe or keyframe segment. The pen tool changes to
the keyframe pointer or keyframe segment pointer .
5
Do any combination of the following:
•
Drag a keyframe or segment up or down to change the value. As you drag, a tool tip
indicates the current value. If no keyframes are present, dragging adjusts the value for
the entire clip or track.
•
Drag a keyframe left or right to change the time location of the keyframe. As you drag, a
tool tip indicates the current time. If you move a keyframe onto another keyframe, the
new keyframe replaces the old one.
Copying and pasting keyframes
To quickly apply the same keyframe values at another point in time or in another clip or
track, copy and paste the keyframes. When you paste, the earliest keyframe appears at
the
current time, and the other keyframes follow in relative order. The keyframes remain
selected after pasting, so you can immediately move them in the destination layer.
