Draw an animation curve in Motion
The Sketch Keyframes tool (next to the Edit Keyframes tool) lets you sketch animation
curves in the Keyframe Editor graph area, creating keyframes as you go. To sketch a curve,
the parameter to animate must first appear in the parameter list. See Create a custom
curve view in Motion for methods of displaying curves.
Sketch an animation curve
1. In Motion, in the parameter list in the Keyframe Editor, select the parameter to sketch.
2. Select the Sketch Keyframes tool (the pencil icon above the parameter list).
3. Drag in the graph area to sketch an animation curve.
Drawing new keyframes overwrites existing keyframes at the frames where you draw.
Add an individual keyframe using the Sketch Keyframes tool
1. In Motion, in the parameter list of the Keyframe Editor, select the parameter to modify.
2. Select the Sketch Keyframes tool (the pencil icon above the parameter list).
3. Click in the graph area to add a keyframe.
Additional clicks create additional individual keyframes.
Transform curve segments in Motion
Use the Transform Keyframes tool to drag a selection rectangle around multiple keyframes
and then manipulate their positions by dragging the bounding box or adjusting its handles.
Dragging the bounding box moves the selected keyframes in whatever direction you move.
As a result, you can affect where the keyframes are positioned in time or you can affect
their parameter values, or you can do both at the same time. Adjusting a bounding box
handle scales the keyframes, changing their timing and parameter values.
