To record fewer keyframes:
1 Choose Mark > Recording Options.
The Recording Options dialog appears.
2 Select from the following recording options:
• Off: Creates a keyframe at every frame (in which movement is applied).
• Reduced: Simplifies the curve.
• Peaks Only: Creates keyframes at only the frames with the greatest shifts in value,
for example, when a change in direction occurs.
Note: To disable the recording of keyframes during playback, turn on the “Don’t record
keyframes during playback” checkbox in the Recording Options dialog. When this is
enabled, you can still create keyframes normally.
Keyframing Objects With Applied Behaviors
In addition to animating objects with keyframes, you can apply behaviors to the
keyframed objects as well. When behaviors and keyframes are applied to an object
simultaneously, the values generated by the behavior and the keyframed values that
are applied to a parameter are added together to yield the final value for that
parameter. This allows you to combine the automatic convenience of behaviors with
the direct control of keyframing to achieve your final result.
In a simple example, you can apply a Spin behavior to create an animation in which an
object rotates. If you then want the object to move from a specific position to another
specific position over time, you can keyframe that object’s position.
For more information on combining behaviors and keyframes, see Chapter 5, “Using
Behaviors,” in Motion Help.
Keyframing in the Dashboard
As mentioned above, when Record is enabled, keyframes are created any time a
parameter value changes. Since Dashboards contain an editable subset of the Inspector
parameters, you can create keyframes using an object’s Dashboard. The following
example uses the Dashboard to animate a simple fade-in effect on an object.
