Copy and paste keyframes in an animation

For the tire to look realistic as it bounces, it should compress slightly on each bounce. You can create this effect by transforming the shape of the tire in Frame 1 of the animation, and copying that frame in Frame 30.

1.
With the Selection tool, select Frame 1 of the TireAnim layer. Then press F6 to add a keyframe.

A new keyframe is added and the playhead moves to Frame 2.
2.
Select Frame 1 of the TireAnim layer again.
3.
In the Tools panel, select the Free Transform tool.

The tire is selected, and transform handles appear around it.
4.
Select the transformation center point (the small circle near the center of the movie clip) and drag it to the bottom of the tire.

The center point snaps to the lower-middle transform handle.
5.
On the Stage, drag the upper-middle transform handle down to slightly compress the tire shape.

If necessary, drag the tire to align it over the shadow. To view the positioning, drag the playhead over Frames 1 and 2.
6.
Save your file.

Note

Always save your document before attempting to manipulate tweens, including copying, cutting, and pasting frames. If you make an error, you can revert to your saved document.
