Adding and Removing Control Points
Placing more control points on an object enables the object to trace more detailed images. For
example, if a segment of an object does not follow a curved section on a frame as well as you
would like, and adjusting the control points and direction bars does not help, you can add a new
control point.
Avid recommends that you remove a control point if the object does not need the control point to
adequately define its shape. It is better to have fewer control points and to manipulate the
direction bars to gain the same effect because fewer control points mean less work if you need to
modify an object later.

To add a control point:
1. Click the Selection tool, and click the object.
2. Do one of the following:
t Click the Reshape tool.
t Double-click the object.
3. Click the selected object where you want to add a new control point.
A new control point appears and is calculated so that the object does not change dramatically
in shape. The new control point appears as part of the object for all keyframes in the
segment.
Any changes you make to a control point, such as moving it or changing the angle of the
associated curve, affect the keyframes you have selected in the segment. If you change a
control point at a selected keyframe or add a keyframe to make changes, the changes are
interpolated between the selected keyframe and adjacent keyframes.
To remove a control point:
t Click the control point, and press the Delete key.
