SMPTE Iris Effects 21

This effect is an implementation of the 26 iris effects from ANSI/SMPTE 258M-1993, plus two Apple-defined wipes that choose a random effect. These are a series of "reveal" type effects that take place between two sources. For full definitions of these 26 iris effects and what they look like, please refer to the SMPTE documentation.

Parameters

Use the descriptions below to help you understand what the parameters do. To learn how to use parameter atoms, see "Adding Video Effects to a QuickTime Movie"

Name	Code	QTAtom Type	Description
Percentage	`'pcnt'`	`kParameterTypeDataFixed` Always a tween	This parameter contains a tween. As the effect progresses, QuickTime renders the frame of the effect indicated by the tween's current value, as a percentage of the whole effect. For example, if the tween goes from 0 to 100, the effect renders completely; if the tween goes from 25 to 75, rendering begins 25% into the effect and terminates 75% through the effect.
Wipe ID	`'wpID'`	`kParameterTypeDataEnum`	The SMPTE ID for the effect. By setting this parameter, you control which of the 26 available iris effects is used.
Soft border	`'soft'`	`kParameterTypeDataBitField` Can be a tween	If this parameter contains `true` , the border drawn around the second source is blurred.
Border width	`'widt'`	`kParameterTypeDataFixed` Can be a tween	The width, in pixels, of a border that is drawn around the second source.
Border color	`'bclr'`	`kParameterTypeDataRGBValue` Can be a tween	The RGB color of the border around the second source.
Horizontal repeat	`'hori'`	`kParameterTypeDataLong` Can be a tween	The number of horizontal repeats of the effect that are executed in a single source.
Vertical repeat	`'vert'`	`kParameterTypeDataLong` Can be a tween	The number of vertical repeats of the effect that are executed in a single source.
