Figure 48. Kurl Menu, Slits Modulation
The Slits modulation soft knob controls and wave patterns are the same as
Position/Size (see Modulation Pane
on page 89 and Figure 44 on page 91 ).
Touching the Slits Controls data pad changes the Kurl menu to display Slits
controls:
Offset — sets the distance adjoining slits move away from each other. This
can be used for transition effects, using a zero offset for the starting key-
frame and an off the screen offset for the ending keyframe.
# of Slits — defines the number of slits.
Phase — determines the starting point or phase of the modulation to occur
at the center point.
Random — defines the degree of randomization of slit width.
Angle — defines the angle of the slits with respect to the source X and Y axes.
Sphere Mode
Sphere is an effect in which the source video is mapped to the surface of a
sphere. Controls are provided which change the aspect and size of the
sphere, the point in source video to be mapped to the center of the front
surface of the sphere, and the horizontal and vertical scaling of the source
video to be mapped.
