• jitter: The opposite of smooth, jitter removes all values except for the noise using the
formula (Unmodified Curve - Smoothed Curve = Jitter). Once the function is applied,
the curve snaps down to approximately the 0 value, so the curve may disappear
(press F or click the Home button to reframe the Editor). This is useful for stabilizing a
jerky camera move. You can keep the overall camera move, but remove the jerkiness.
The vertical scale of this image is much smaller than the first example snapshot.
• reverse: Makes the curve go backward in time.
