Motion Add or delete keyframes
To add or delete keyframes in the Keyframe Editor, select the Edit Keyframes tool (above the parameter list), then perform the following tasks:
Add a keyframe
-
In the parameter list (on the left side of the Keyframe Editor), click the Animation menu for any parameter, then choose Add.
Note: The Animation menu (a downward arrow) is hidden until you place the pointer over the right side of the parameter’s row in the list.
A keyframe is added at the position of the playhead.
Add a keyframe to an existing animation curve
-
In the Keyframe Editor, double-click or Option-click the animation curve in the graph area.
A keyframe is added to the curve at the pointer position. The new keyframe is set to the interpolation method used by the rest of that curve. For example, Position parameters use Bezier curves by default, so new keyframes are added as Bezier keyframes. For more information on interpolation methods, see Set curve interpolation.
Add a keyframe to an animation curve and adjust its value
-
In the Keyframe Editor, Option-drag a curve segment.
A keyframe is added to the segment at the pointer position, and its value is displayed as you drag the keyframe.
Delete a keyframe
Do one of the following:
-
Select the keyframe in the Keyframe Editor, then press Delete.
Note: You can drag a selection box around multiple keyframes.
Control-click the keyframe, then choose Delete from the shortcut menu.
-
Navigate to the keyframe, then click the Animation menu for the keyframed parameter and choose Delete.
The Animation menu is hidden until you place the pointer over the right side of a parameter row.
Delete all of a parameter’s keyframes
-
In the parameter list in the Keyframe Editor, click the Animation menu for a parameter, then choose Reset Parameter.
The Animation menu is hidden until you place the pointer over the right side of a parameter row.
Note: You can also use the corresponding Animation menu in the Inspector.
