Changing several keyframe values at once

You can change the values of multiple keyframes on multiple layers at one time; however, all keyframes you select must belong to the same layer property. The way the values change depends on the method you use to make the change:

• If you change a value numerically, all selected keyframes use the new value exactly. In other words, you make an absolute change. For example, if you select several Position keyframes on a motion path and numerically specify a Position value for one of them, all selected keyframes change to the same position value.
• If you change a value by dragging the underlined value, all selected keyframes change by the same amount. In other words, you make a relative change. For example, if you select several Position keyframes on a motion path and drag the underlined value for one of them, all selected keyframe values change by the same amount.
• If you change a value graphically in the Composition or Layer window, all selected keyframes change using the difference between the old and new values, not the values themselves. In other words, you make a relative change. For example, if you select several Position keyframes on a motion path and then drag one of them 10 pixels to the left, they all move 10 pixels to the left of their original positions.

You can also change the value of several layers at once by parenting them. (SeeUnderstanding parent layers.)

To set multiple keyframes to the same value:

1. Select the keyframes you want to change. All keyframes you select must be for the same property. (See Navigating to and selecting keyframes.)
2. Change the value of any selected keyframe by one of the methods above. All other selected keyframes change accordingly.
