You can also adjust each edge of the image individually using the Left, Right, Top, and
Bottom parameters in the Crop section of the Video inspector.
Note: Although you can use these controls to change the crop window’s aspect ratio,
the final image still matches the original image’s aspect ratio, with additional content
being cropped out so that the final image fits the original aspect ratio.

You can animate the effect, creating the illusion of a pan and zoom camera move
(effectively, a manual Ken Burns effect). See Work with built-in effects in Final Cut Pro.
Pan and zoom clips in Final Cut Pro
The Ken Burns effect creates a pan and zoom effect using the start and end positions you
define. The Ken Burns effect is actually a Crop effect with two crop settings, one at the clip
start and another at its end.
You can further customize the Ken Burns effect by controlling the smoothness of the
animation. The motion applied to a clip when you create a Ken Burns effect is automatically
smoothed so that the movement accelerates slowly as the animation starts, and
decelerates slowly as the clip comes to rest at the end of the animation. This simulates the
effects of friction and inertia that occur in the real world. In visual effects software, this
trick is commonly called ease out and ease in.
By default, a Ken Burns animation performs both of these smoothing operations (Ease Out
and Ease In), but you can customize the effect to limit the result to just easing out, just
easing in, or making a linear movement with no simulated inertia or friction.
