KeyframeEase object¶

myKey = new KeyframeEase(speed, influence);

Description¶

The KeyframeEase object encapsulates the keyframe ease settings of a layer's AE property. Keyframe ease is determined by the speed and influence values that you set using the property's setTemporalEaseAtKey method. The constructor creates a KeyframeEase object. Both parameters are required.

speed: A floating-point value. Sets the speed attribute.
influence: A floating-pointvalue in the range [0.1..100.0]. Sets the influence attribute.

Example¶

This example assumes that the Position, a spatial property, has more than two keyframes.

var easeIn = new KeyframeEase(0.5, 50);
var easeOut = new KeyframeEase(0.75, 85);
var myPositionProperty = app.project.item(1).layer(1).property("Position");
myPositionProperty.setTemporalEaseAtKey(2, [easeIn], [easeOut]);

This example sets the Scale, a temporal property with either two or three dimensions. For 2D and 3D properties you must set an easeIn and easeOut value for each dimension:

var easeIn = new KeyframeEase(0.5, 50);
var easeOut = new KeyframeEase(0.75, 85);
var myScaleProperty = app.project.item(1).layer(1).property("Scale")
myScaleProperty.setTemporalEaseAtKey(2, [easeIn, easeIn, easeIn], [easeOut, easeOut, easeOut]);

Attributes¶

KeyframeEase.influence¶

myKey.influence

Description¶

The influence value of the keyframe, as shown in the Keyframe Velocity dialog box.

Type¶

Floating-point value, in the range [0.1..100.0]; read/write.

KeyframeEase.speed¶

myKey.speed

Description¶

The speed value of the keyframe. The units depend on the type of keyframe, and are displayed in the Keyframe Velocity dialog box.

Type¶

Floating-point value; read/write.
