Every clip in the Quick view timeline or the Expert view timeline automatically has the Motion effect applied to it. You use the Motion effect to position, rotate, or scale a clip within the video frame. You can also use the Motion effect to set the anchor point. Position, Scale, and Rotation values are calculated from the anchor point, which lies at the center of the clip, by default.
Because the Position, Scale, and Rotation properties are spatial in nature, it’s best to adjust them directly in the Monitor panel.
