TUNNEL

Tunnel will expand the colors of an image around a user-defined circle in order to simulate a reflective "tunnel." 

SLIDERS

X & Y - Define the center of the tunnel. (In iMovie 2.1.1 and higher, the X and Y values are set by picking a point in the small preview window.)

Radius - Defines the radius of the "far-end" of the tunnel.

USAGE

This effect can also be used in conjunction with iMovie's titles to create some very interesting graphics.

INDEX
ZOOM

The Zoom effect allows the user to zoom in on a portion of the clip to which the effect is applied. 

SLIDERS

Zoom: This controls the Zoom factor of the effect.

X & Y - Define the center of the portion of the image to be enhanced. (In iMovie 2.1.1 and higher, the X and Y values are set by picking a point in the small preview window.)

USAGE

This effect can also be used for "cropping" or cutting out undesired portions of an image, leaving just the good parts. This effect is optimized to look best when output to a DV tape or a television, and may look slightly fuzzy on your computer screen in iMovie.
