You can copy keyframes from only one layer at a time. When you paste keyframes into
another layer, they appear in the corresponding property in the destination layer. 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.
Note: When copying and pasting between the same properties, you can copy from more
than one property to more than one property at a time. However, when copying and
pasting to different properties, you can copy only from one property to one property at a
time.
To copy and paste keyframes:
1 In the Timeline window, display the layer property containing the keyframes you want
to copy.
2 Select one or more keyframes. See "Navigating and selecting keyframes" on page 99.
3 Choose Edit > Copy.
4 In the Timeline window containing the destination layer, move the current-time marker
to the point in time where you want the keyframes to appear.
5 Do one of the following:
To paste to the same property of the copied keyframes, select the destination layer.
•
To paste to a different property from the copied keyframes, select the destination
•
property.
6 Choose Edit > Paste.
Moving a layer duration bar independently of its keyframes
Once you set keyframes, they maintain their position relative to their layer's duration bar. If
you move the duration bar earlier or later in the composition, its keyframes move with it.
You can prevent this by cutting and pasting keyframes.
To move keyframes without moving the layer duration bar, select the keyframes and drag
them. See "Moving keyframes" on page 100. You can also change the displayed frames of a
trimmed layer without moving either its keyframes or the layer duration bar. See "Moving
a trimmed layer in time" on page 83.
To move a layer duration bar but not its keyframes:
1 Make a note of the time at which the first keyframe appears.
2 In the layer outline, click the name of one or more layer properties containing the
keyframes you want to keep at the same times.
3 Choose Edit > Cut.
4 Move or stretch the layer duration bar to its new In and Out points.
