Drop Shadow Parameters
This attribute places a drop shadow behind a clip.

 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 button: Lets you quickly select a color that’s in an image in the Viewer
or the Canvas. Click this button, then click an image in the Viewer or the Canvas to

determine the direction on the color wheel Final Cut Pro uses to interpolate the
color change.

Motion Blur Parameters
Motion blur affects any clip that has motion, whether it’s a moving subject in a video
clip, or keyframed motion effects that you’ve created.
The Motion Blur parameter allows you to create or exaggerate motion blur in ordinary
video clips. For example, if you apply motion blur to a clip where someone is standing
still and waving an arm, the arm becomes blurred, while the rest of the image remains
sharp. This happens even though the arm waving is not a keyframed motion effect. The
Motion Blur parameter also lets you add motion blur to video clips that have none,
such as computer animation that was rendered without it.
Motion Blur can also add blur to layered clips that are moving due to keyframed
motion effects, such as animated motion along a path, rotation, changes in scale, or
distortion. This way, animated motion within Final Cut Pro can be given a more natural
look, as if the moving clips were actually recorded with a camera.
