Using the Keyframe Interpolation dialog box

The Keyframe Interpolation dialog box provides options for setting temporal and spatial interpolation and, for spatial properties only, roving settings. (See Creating smooth changes using roving keyframes.)

To change an interpolation method for a keyframe using the Keyframe Interpolation dialog box:

1. In the Timeline window, select the keyframes you want to change. Note whether the property is spatial (if it has a speed graph) or temporal (if it has a velocity graph).
2. Choose Animation > Keyframe Interpolation.
3. For Temporal Interpolation, choose one of the following options:
• Current Settings preserves the interpolation values already applied to the selected keyframes. Choose this option when multiple or manually adjusted keyframes are selected and you do not want to change the existing settings.
• Linear, Bezier, Continuous Bezier, Auto Bezier, and Hold apply a temporal interpolation method using default values.
4. If you selected keyframes of a spatial layer property, choose one of the following options for Spatial Interpolation (available only for Position, Anchor Point, Effect Point, and 3D Orientation keyframes):
• Current Settings preserves the interpolation settings already applied to the selected keyframes.
• Linear, Bezier, Continuous Bezier, and Auto Bezier apply a spatial interpolation method using default values.
5. If you selected keyframes of a spatial layer property, use the Roving menu to choose how a keyframe determines its position in time, and then click OK:
• Current Settings preserves the currently applied method of positioning the selected keyframes in time.
• Rove Across Time smooths the rate of change through the selected keyframes by automatically varying their position in time, based on the positions of the keyframes immediately before and after the selection.
• Lock to Time keeps the selected keyframes at their current position in time. They stay in place unless you move them manually.
