b Choose an option from the Borders pop-up menu:
 Choose Normal to maintain the size of the stabilized footage. The resulting
transformations that are made to the stabilized image may cause moving black
borders to appear around the edges of the clip.
Note: For suggestions on correcting the black borders, see “Removing Black Borders
Introduced by Stabilizing” on page 95.
 Choose Zoom to expand the clip to the full size of the Canvas. This prevents black
borders from appearing around the edges of the stabilized clip.
c Choose an option from the Direction pop-up menu:
 Choose Horizontal and Vertical to apply the stabilize transformation to the X and Y
dimensions.
 Choose Horizontal to apply the stabilize transformation to the X dimension.
 Choose Vertical to apply the stabilize transformation to the Y dimension.
Normal borders maintain the size of the stabilized
clip but create black borders around the clip’s edges.
Zoomed borders scale the stabilized clip so the clip
does not move away from the edge of the Canvas.
