Apply Ease Curve or Apply Multiplier Curve

Apply - Ease Curve and Apply - Multiplier Curve (available from the Curves menu in the Curve Editor) create an ease curve or multiplier curve track. These tracks let you modify or intensify an existing animation track without changing the original track.

A multiplier curve shifts the value of the original track up or down.
Adjusting the multiplier curve increases or decreases the “intensity” of the original track.
An ease curve shifts the time of the original track left or right.
Adjusting the ease curve changes time. The value of the ease curve at a particular frame is a frame value from the original track. For example, if the ease curve is 0 at frame 0 and 10 at frame 10, the original track plays at its original speed. If the ease curve value at frame 10 increases to 20, the original track plays to frame 20 by frame 10: it has been sped up by a factor of two.

Once you apply an ease or multiplier curve, you can edit its keys, ranges, and properties just like any other animation track.

One use of ease and multiplier curves is to blend between the effects of different controllers. This can be an aid to nonlinear editing.

Procedures

To apply an ease curve or a multiplier curve:

In the Curve Editor Hierarchy list, highlight the tracks you wish to ease or intensify.
Not all controller items can receive ease or multiplier curves. For example, the Path Constraint position controller cannot receive an ease or multiplier curve, but its subordinate Percent controller can. If the highlighted controller is incapable of receiving ease or multiplier curves, nothing happens when you apply the curve.
From the Curves menu, choose Apply - Ease Curve or Apply - Multiplier Curve.
In the Controller window expand the highlighted tracks to view the ease curve.
Hold down the Ctrl key and click the ease curve and controller tracks.
Adjust the keys on the ease curve and watch the result in the controller curve.
Use a Multiplier curve to intensify an effect, or an ease curve to make less of an effect.

TipUse Step interpolation to use the ease curve to turn tracks on and off.

Interface

Apply - Ease Curve: Applies a curve to alter the timing of the selected function curve. Ease curves vary the timing of a superior function curve. A normal function curve charts an animated parameter value over time. An ease curve charts changes to the timing of a function curve over time.
Apply - Multiplier Curve: Applies a curve to scale the value of the selected function curve. The value of a multiplier curve is a scale factor applied to the value of its superior function curve.

You apply ease and multiplier curves in Curve Editor mode. Once you apply an ease or multiplier curve, you can edit its keys, ranges, and properties, as with any other animation track.
