Keyframing ❚❘❘ Keyframing You can animate a layer by setting at least two keyframes for the layer's categories at different times. A keyframe is a point in time that records any change to a layer in your workspace. Before you can create keyframes, you must enable the Animate button. For more information on animating using keyframes, see Chapter 12, "Creating Animations''. Use keyframing to add motion to layers in your composite (or, in the above example, rotation to the windmill's vanes). To animate a layer using keyframes: 1. To the right of the Playback controls, enable the Animate button (A). Keyframe at frame zero 6. Press the END key to move to the last frame. 7. Change the value for the Z Rotation channel. To do so, click and drag your cursor over the Z Rotation value in the Timeline list, or click the Composite Controls tab and use the Transform controls. A keyframe is set at the last frame. The between the keyframes are determined automatically using interpolation. 2. Select a layer (for instance, we select the Vanes layer from the illustration above to rotate the windmill's vanes). 3. Press the HOME key to move to the first frame of the animation. 4. Use the Transform controls to set a rotation category at the first frame of the animation. For instance, set the Z Rotation to 130°. 5. Click the Timeline tab, expand the layer that you want to animate, and then expand the Transformation category. You can see a keyframe has been set for the Z Position channel. Keyframe at last frame 8. Click the Graph button to see the shape of the interpolated animation curve. Graph button Animation curve 9. Move back to the first frame, and then press the Play button in the playback controls to watch the animation. 69
