//  File:       QTShowEffect.h

//

//  Contains:   Code to generate a QuickTime movie with a QuickTime video effect in it,

//              and to preview an effect on zero, one, or two pictures.

//

//  Written by: Tim Monroe

//              Based on existing ShowEffect code written by Dan Crow,

//              which was adapted from Peter Hoddie's original DoEffect code.
