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.) 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.)

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.
5. Move the current-time indicator to the time at which the first keyframe appeared before you cut the keyframes.
6. Choose Edit > Paste.
