Ease In Time: A slider that sets the number of frames over which the ease in to the speed
change occurs (from the start of the behavior). The default value is 20 frames.
Ease In Curve: A slider that defines the curvature of the ramp when easing into the speed
change. A value of 0 creates a sharp transition to the new speed; a value of 100 creates
the smoothest ease in to the new speed. The default is 50%.
Ease Out Time: A slider that sets the number of frames over which the ease out of the
speed change occurs (from the end of the behavior). The default value is 20 frames.
Ease Out Curve: A slider that defines the curvature of the ramp when easing out of the
speed change. A value of 0 creates a sharp transition from the new speed to the original
speed; a value of 100 creates the smoothest ease out. The default is 50%.
HUD Controls
The HUD contains the Speed, Ease In Time, Ease In Curve, Ease Out Time, and Ease Out
Curve parameters.
Strobe
The Strobe behavior simulates the look of a strobe light or lower frame rate video by
holding a number of frames as defined by the Strobe Duration parameter over the playback
of the clip. For example, when Strobe Duration is set to 10, frame 1 is held for 10 frames,
frame 11 for 10 frames, frame 21 for 10 frames, and so on. The frames in between (2–10,
12–20, 22–30, and so on) do not appear.
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 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.
