The following replaces the text in the “Animating the birds” and “Animating the Clouds” sections, which begin on page 165 of the printed book. Continue with the original book from the “Previewing the animation” section. The illustrations remain accurate.
Next, you’ll animate the motion of the birds flying by. To create the animation faster, you’ll take advantage of the Auto-Keyframe option. When Auto-Keyframe is enabled, After Effects automatically creates a keyframe whenever you change a value.
1. Select the Birds layer in the Timeline panel, and press P to reveal its Position property.
2. From the Timeline panel menu, choose Enable Auto-Keyframe.
