Change Position keyframes in a motion path

You can change the value of a Position keyframe, and thereby adjust your motion path, simply by dragging the Position keyframe (indicated by a white X) in the Program Monitor.

1Select a clip that has Motion effect keyframes.

2In the Effect Controls panel, click the Transform icon next to Motion. The clip’s motion path appears in the Program Monitor.

3Do any of the following:

•To move an existing keyframe, drag the keyframe handle in the Program Monitor.

•To create a new position keyframe, set the current-time indicator between existing keyframes and drag the clip in the Program Monitor to the desired location. A new keyframe appears in the Effect Controls panel, the Program Monitor, and in the clip in the Timeline panel.

Note: This procedure changes the position value at a keyframe. To change the timing of keyframes, move Keyframe icons in the Effect Controls panel.

Move a clip along a curve

You can move a clip along a curve using Bezier handles in the Program Monitor.

1Select a clip in a Timeline panel.

2Move the current-time indicator in either a Timeline panel or the Effect Controls panel to the time where you want to start the animation—any frame between the clip’s current In point and its Out point.

3Click the triangle next to the Motion control in the Effects Controls panel.

4Click the Toggle Animation button next to the Position control to set the first keyframe.

5Drag the current-time indicator in either a Timeline panel or the Effect Controls panel to the frame where you want to end the animation.

6In the Program Monitor, drag the clip to the location where you want the clip at the end of its movement.

A motion path appears in the Program Monitor connecting the start and end points of the clip’s motion. Small Bezier handles appear near either end of this motion path.

7Drag either or both of the Bezier handles in any direction to create curves in the motion path.

8In the Effect Controls panel, right-click (Windows) or Control-click (Mac OS) a Position keyframe.

9Select a type of acceleration from either the Temporal Interpolation or the Spatial Interpolation menu.

10Drag the current-time indicator to the first keyframe and press Enter (Windows) or Return (Mac OS) to preview the motion of the clip.

Adjust or animate clip anchor points

By default, a clip anchor point is set at the exact center of a clip. You can change the position of a clip in relation to its frame or motion path, however, by moving the clip anchor point. Further, you can change the location of the clip anchor point over time, allowing the clip to move in relation to its frame or motion path. Animating the clip anchor point can be used, for example, to create an image-panning effect.

1In a Timeline panel, place the current-time indicator at the beginning of a clip.

2Click on the clip in the Program Monitor.

The clip anchor point becomes visible at the center of the clip.
