The animated filter makes it seem like you are looking at the image through a rotating
kaleidoscope.
Note: You can also animate filters using the same methods discussed in “ Keyframing in
the Dashboard ” on page 113 and “ Keyframing in the Inspector ” on page 114.
Converting Behaviors to Keyframes
Behaviors are best suited for fluid effects in which precise timing is not a requirement.
As mentioned earlier, behaviors create motion by applying a range of values to an
object’s parameters, without creating keyframes. You then generally adjust the rate of
the behavior. When your project requires absolute timing, for example, when a title
must fade in over 60 frames, rotate 360 degrees exactly 3 times, and land in a specific
position on the screen, you would generally keyframe your animation.
For finite control over animated effects created with behaviors, several of the behaviors
can be baked into keyframes. You can then modify the keyframes in the Keyframe
Editor to meet more precise timing requirements.
Since many (though not all) behaviors affect shared object parameters, when you
convert a behavior to keyframes, all behaviors applied to that object are also converted
into keyframes. For example, the Gravity and Throw behaviors affect Position, so you
could not convert the Gravity behavior to keyframes without affecting the Throw
behavior.
Note: You cannot convert many of the Simulation behaviors into keyframes. Simulation
behaviors such as Vortex can affect the parameters of all objects within a project, and
baking such a behavior would create an overwhelming amount of keyframes (and
motion graphics artists everywhere would run screaming from their computers).
Remember, the beauty of such behaviors is that they automatically create very complex
motion that would be too time-consuming to keyframe manually.
