Motion Path Filter

231

You can manipulate velocity curves in the same way as value curves, except that velocity

curves do not include keyframe points. For more information, see “Manipulating the Value

Curve” on page 229.

Motion Path Filter

The Motion Path filter allows you to map one or more objects to a two-dimensional path.

You create the path by drawing a spline object. You can map single tracks, multiple tracks,

or 3D containers to the path. Although the path is two-dimensional, you can rotate, tumble

or spin the container to move the path in three-dimensional space.

To create a Motion Path Effect

1. In the timeline, select the track, or container that you want to map to the path.

2. Choose

Filters > Motion > Motion Path

A Motion Path track is added to the timeline.

3. Click the

disclosure triangle

to expand the Motion Path track, and select the

Path track

nested inside.

The Motion Path turns pink, and the Path track below it turns dark gray. The

Tool

window

automatically opens so that you can create a path.

You can also open the Tool window by choosing

Window > Show Tool Window

, or pressing

Control–6

4. Select a tool and draw a path by dragging in the Composite window.

The Composite window updates, showing the object mapped to the Motion On Path tab.

The example at right was created with the Pen tool.
