Stutter, Simulation behaviors – Apple Motion 4 User Manual

Parameters in the Inspector
Strobe Duration:
A slider that sets the number of frames to hold. A value of 1 plays the
clip at normal speed. The default value is 5 frames.
HUD Controls
The HUD contains the Strobe Duration parameter.
Stutter
This behavior randomly inserts hold frames, of random durations, into the playback of a
clip. The effect is similar to a tape that sticks during play in a videocassette recorder.
Parameters in the Inspector
Stutter Amount:
A slider that sets the probability that a hold frame is generated at the
given frame. When set to 0%, no hold frames are created; when set to 100%, every frame
is a hold frame. Values in between 0 and 100 indicate the probability of frames (within
the duration of the behavior) that are replaced by hold frames. The default value is 10%.
Duration Range:
A slider that sets the maximum duration of hold frames. A value of 1
inserts single-frame hold frames at a frequency determined by the Stutter Amount
parameter. Increasing the Duration Range increases the range of hold frames. For example,
a value of 30 creates random hold frames with a minimum of 1 frame and a maximum
of 30 frames. The default value is 3 frames.
Random Seed:
A button that lets you pick a new random seed number. This number is
used to randomly generate new values, based on the other parameters of this behavior.
HUD Controls
The HUD contains the Stutter Amount, Duration Range, and Random Seed parameters.
Simulation Behaviors
These behaviors perform one of two tasks. Some Simulation behaviors, such as Gravity,
animate the parameters of an object in a way that simulates a real-world phenomenon.
Other Simulation behaviors, such as Attractor and Repel, affect the parameters of one or
more objects surrounding the object to which they’re applied. These behaviors allow you
to create some very sophisticated interactions among multiple objects in your project
with a minimum of adjustments. Like the Basic Motion behaviors, Simulation behaviors
also affect specific object parameters. Examples include Attractor, Gravity, and Repel.
