Use the Motion effect to position, scale, or rotate a clip within the video frame. To animate clips, you must set keyframes for Motion properties.
By default, each clip that you add to a Timeline panel has the Motion effect applied as a fixed effect. You can view and adjust the Motion effect properties in the Effect Controls panel by clicking the triangle next to the Motion name. Motion properties can be directly manipulated in the Program Monitor or using the controls in the Effect Controls panel. Motion properties can be controlled with Bezier handles.
By default, a clip appears at 100% of its original size in the center of the Program Monitor. Position, scale, and rotation values are calculated from the clip anchor point, which lies at the clip’s center by default.
Because the Position, Scale, and Rotation properties are spatial in nature, it’s easiest to adjust them directly in the Program Monitor. When you click the Transform icon next to the Motion effect in the Effect Controls panel, handles appear on the clip in the Program Monitor that let you directly manipulate the clip and adjust the Motion effect properties.
You can directly move the anchor point of the Motion built-in effect in the Program Monitor. To achieve a finer control over the anchor point location, you can use the Anchor Point property in the Effect Controls panel. Any changes to the anchor point in the Program Monitor are updated in the Effect Controls panel and vice versa.
