Animating Layers
To add additional keyframes for a layer property:
1 In the Timeline window, select the layer you want to animate.
2 Display the layer property for which you want to add a keyframe. It must already
contain at least one keyframe, and the stopwatch must be activated.
3 Move the current-time marker to the point where you want to add a new keyframe, and
change the value for the layer property you are animating. After Effects adds a keyframe
automatically.
To add a keyframe without changing a value:
1 Display the Timeline window for the composition containing the layer you want to
animate.
2 Display the layer property for which you want to add a keyframe. The property must
already contain at least one keyframe, and the stopwatch must be activated.
3 Move the current-time marker to the point where you want to add a new keyframe. If the
current-time marker is after the last keyframe for that layer property, the new keyframe will
have the same value as the preceding keyframe. Otherwise, the new keyframe’s value will be
an interpolated value based on the previous and next keyframe values.
4 Do one of the following:
• Click the keyframe check box for the layer property.
• Choose Animation > Add x Keyframe, where x is the name of the property you are
keyframing.
Navigating and selecting keyframes
If you want to modify or copy a keyframe, first select it. After Effects provides many
methods for navigating to and selecting one or more keyframes.
