8 Click the Record button (or press A) to turn off keyframe recording.
The filter now changes over time to reflect your settings. This same technique can be
applied to any parameter in any filter that appears in the HUD.
Animating Behaviors
In addition to animating filter parameters, you can also animate behaviors. Animating
behaviors might appear complicated at first because most of the behaviors are already
changing, but combining these features is a powerful way to greatly enhance behaviors’
usefulness. For example, you might want to animate a Random Motion behavior to begin
as a subtle random motion and then become increasingly severe as the effect progresses.
Or you might want to apply a Gravity behavior, but you don’t want the object to start
falling toward the ground until five seconds into the clip. Keyframes allow you to
manipulate the specific parameters of each behavior.
Note: In Motion, you can bake all the behaviors that have been applied to an object into
keyframes using the Convert to Keyframes command in the Object menu. For more
information, see
Converting Behaviors to Keyframes .
To animate a behavior
1 Select an object in the Canvas.
2 Apply a behavior.
3 Click the Record button (or press A) to turn on keyframe recording.
4 Place the playhead at the frame where you want the effect to begin changing.
5 Using the HUD, adjust the behavior’s settings.
6 Move the playhead to a new time position.
7 Adjust the behavior settings again.
8 Click the Record button (or press A) to turn off keyframe recording.
Animating Using the Inspector
Although you can animate many attributes using the HUD, many other parameters are
only accessible in the Inspector. All of the Inspector’s tabs contain keyframeable
parameters. In this way, you can animate the position and shape of a mask, the color and
styles of a text object, or the various options within the generators. The parameters that
are keyframeable depend on which object is selected and which effects have been applied
to that object.
You can animate parameters in the Inspector using the Record button and the
mini-Timeline playhead just as you would animate parameters in the Canvas or HUD.
To animate parameters in the Inspector
1 Select the object you want to keyframe in the Canvas.
