708 Chapter 10 Using Filters
To animate filter parameters using the Animation menu:
1 Select the filter you want to animate.
2 Go to the frame where you want to add a keyframe.
3 In the Inspector, click the Animation menu for the parameter you want to animate,
then choose Add Keyframe from the menu.
4 Change the value of the parameter to the desired value.
5 Go to the next frame where you want a keyframe.
6 Repeat steps 3 and 4 until you are finished.
Note: Remember to add a keyframe before adjusting a parameter value.
For more detail on using keyframes and the animation menu, see “ The Animation
Menu ” on page 415.
Applying Behaviors to Filter Parameters
Animating filter parameters is easy using Parameter behaviors. For example, if you have
an object with an applied Circle Blur filter, you can randomize the amount of blur
applied to the object over time.
To randomize the blur applied to an object:
1 Select the object with the applied blur filter.
2 In the Inspector, open the Filters tab.
3 Select the Amount parameter.
