Method: This pop-up menu defines how the stabilization is applied to the clip.
 Stabilize: This method attempts to lock the motion of the principal subject in the
shot to eliminate motion. As a result, the background will appear to move around
the subject being tracked.
 Smooth: This method smooths the apparent motion of the camera, while allowing
the general movement in the frame to proceed. It’s useful for removing jitter from a
camera move. When enabled, this mode has three sliders for each of the dimensions
that can be smoothed.
 Translation Smooth: Smooths motion in both the X and Y dimensions.
 Rotation Smooth: Smooths image rotation.
 Scale Smooth: Smooths an uneven zoom.
Note: Don’t set the Scale Smooth above 0 unless you’re positive that the image is
being zoomed.
Borders: When a clip is stabilized, the resulting transformations that are made to the
stabilized image may cause moving black borders to appear around the edges of the
clip. This pop-up menu defines how the edges are handled.
 Normal: Maintains the size of the stabilized footage. The moving black borders
remain around the edges of the clip.
