Distort Parameters
Change a clip’s Distort parameters to alter the rectangular shape of a clip or to give it a
different aspect ratio.
 Upper Left, Upper Right, Lower Right, Lower Left: You can change the shape of a clip by
moving each of four corner points independently of one another. The corner points
defining the relative distortion of a clip are offset relative to the center of the clip.
 Aspect Ratio: Allows you to squeeze a clip horizontally or vertically to change the
ratio of its width to its height. This parameter never increases a clip’s size. You can
enter values between –10,000 and 10,000 in the number field.
Opacity Parameter
Change a clip’s opacity to make it appear solid or with a relative transparency against a
background image.
 Opacity: Increases or decreases the transparency of a clip.
Drop Shadow Parameters
This attribute places a drop shadow behind a clip.
 Offset: Determines how far away from the clip the drop shadow falls.
 Angle: Determines which angle the drop shadow falls toward.
 Color: There are several controls you can use to determine the color of the drop
shadow.
 Disclosure triangle: Click to display sliders and number fields corresponding to the
hue, saturation, and brightness (H, S, and B) of the chosen color for the drop shadow.
 Eyedropper: Lets you quickly select a color that’s in an image in the Viewer or the
Canvas. Select the eyedropper, then click an image in the Viewer or the Canvas to
pick up that color.
 Hue direction control: If you’re keyframing changes in color, click this control to
determine the direction on the color wheel Final Cut Express uses to interpolate
the color change.
 Color picker: Click to choose a color using the standard color picker.
 Softness: Blurs the drop shadow around its edges.
 Opacity: Sets the transparency of the drop shadow.
