The density of dots between the boxes in a motion path indicates the relative speed of the layer or effect control point.
Dots close together indicate a lower speed; dots farther apart indicate a greater speed.
Note: Right-click (Windows) or Command-click (Mac OS) a keyframe to open its context menu.
Using the Pen tool or Selection tool to edit keyframes for a spatial property in the Composition or Layer panel is like
modifying a Bezier path for a mask or for a shape on a shape layer. (See
A motion path is less complex and generally easier to modify when you use fewer keyframes to describe the path. You
can use the Smoother to remove extraneous keyframes from a motion path.
Jonas Hummelstrand and Dan Ebberts provide an animation preset and instructions on the
for scaling and rotating a motion path.
