Slide (`slid')

In an Slide effect source B slides onto the screen to cover source A. At the end of the effect, source B will completely cover source A. The angle from which source B enters the frame is stored in a parameter, with 0 being the top of the screen.

Example:

In the example above, the angle parameter is tweened, causing source B to approach from a changing angle.

The Slide effect takes a maximum of two sources and has two 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.

Slide Angle

`angl'

Fixed

The angle from which source B will enter the frame. This value is expressed in degrees, with 0 degrees defined as the top of the screen.
