Import two video files into a new project. Then, adjust your work area so that it’s laid out for working with effects by choosing Window > Workspace > Effects.

If you want to overlap one clip with another, determine which clip will be in front and move that clip to Video track 3. Place the remaining clip in Video track 2, directly below the clip in track 3. Trim both clips to the same length and align their In and Out points. Next, create a color matte to serve as a border: Choose File > New > Color Matte. Place the color matte on Video track 1 and stretch it to the same length as the clips.

Select the clip in Video track 3 and choose Window > Effect Controls. The Effect Controls window opens, displaying the Fixed Effects. These effects are built into each clip and allow you to change intrinsic properties of a clip. Expand the Motion effect to view its position, scale, and rotation properties.

Click the Motion effect so that it’s highlighted.

The handles that appear on the corners and sides of the clip in the Program view of the Monitor window allow you to manipulate the clip.

If you’re unable to see the clip handles, make sure the Motion effect is selected in the Effect Controls window and change the zoom level of the Program view to a lower percentage.
