Cross Fade (`dslv')

A "cross fade" or "dissolve" provides a smooth alpha blending between two video sources which changes over time to give a smooth fade out from the first source into the second.

Example:

This effect takes a maximum of two sources, and has a single parameter.

Parameters

Description

Percentage

`pcnt'

Fixed

This parameter is a tween. QuickTime will render the frame of the effect indicated by the tween's current value, as a percentage of the whole effect. If the tween goes from 0 to 100, the effect renders completely. If the tween goes from 25 to 75, for example, rendering begins 25% into the effect and terminates 75% through the effect.
