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 the 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 anchor point, which lies at the clip’s center.
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. Although the anchor
point also appears in the Program Monitor, it can be adjusted only
in the Effect Controls panel. However, the Program Monitor updates
any changes to the anchor point as you make them. 
Standard effects that allow direct manipulation
of clips in the Program Monitor include all the Generate effects,
Corner Pin, Crop, Garbage Matte, Lighting Effects, Mirror, Transform,
Twirl, and more. This capability is indicated by the Transform icon
