Scale Randomness: Defines an amount of variance in the scale of the replicator elements.
A value of 0 results in no variance—all elements in the pattern are the same size. A value
greater than 0 introduces a variance. The scale for an individual element is defined by
the Scale parameter, plus or minus a random value falling within the Scale and the Scale
End. The disclosure triangle of the Scale Randomness parameter reveals separate X and
Y subparameters that can be used to set the width and height values separately.

Play Frames: This checkbox appears if you create a replicator pattern using a QuickTime
object as the source for a cell. When this checkbox is selected, playback of the animation
or movie clip used for each element will loop. If this checkbox is deselected, animation
or clip will be frozen at the still frame specified by either the Random Start Frame
parameter or the Source Start Frame parameter.
Random Start Frame: This checkbox appears if you create a replicator pattern using a
QuickTime object as the source for a cell. Use this control to introduce variation into
elements using QuickTime animation or movies as their source objects. When this checkbox
is selected, each element in the pattern begins at a different frame of the clip. Stills are
chosen randomly if Play Frames is deselected.
Source Start Frame: This slider appears if you create a replicator pattern using a QuickTime
object as the source for a cell. The value selected in the slider designates the start frame
of the clip (when the Play Frames checkbox is selected) or the still frame to display (when
Play Frames is deselected). This parameter appears only if Random Start Frame is
deselected.
