Working with Masks and Transparency

Note: When you animate rotation using Free Transform Points, the vertices of the mask are

interpolated in a straight line from keyframe to keyframe. Because of this, the results may be

different than you expect.

A. Free Transform Points bounding box B. Bounding box handle

C. Bounding box anchor point D. Layer anchor point

To move, scale, or rotate a mask or control points:

sition or Layer window.

2 With the selection tool chosen, do one of the following:

• To change a certain number of points, select the control points you want to transform

and choose Layer > Mask > Free Transform Points.

• To transform the entire mask, select it in the Timeline window and choose Layer > Mask

> Free Transform Points.

3 To move the bounding box’s anchor point, position the selection tool over the

bounding box anchor point ( ) until the selection tool changes to a move anchor point

icon ( ). Drag to position the anchor point.

4 Do any combination of the following:

• To move the mask or selected points, position the pointer inside the bounding box

and drag.
