Last updated 8/12/2010
Mirror
The Mirror effect creates a mirror image of the clip and places the center of its side at a pivot point you specify. You
can make both the location of the pivot point and the reflection angle change over time.
Reflection Center
Setting the first value determines the horizontal location of the pivot point. Setting the second
determines its vertical location.
Reflection Angle
Setting this value determines the angle at which the mirror image pivots at the pivot point.
Polar Coordinates
The Polar Coordinates effect distorts a clip by moving each pixel in the clip’s x,y coordinate system to the corresponding
position in the polar coordinate system, or the reverse. This effect produces unusual and surprising distortions that can
vary greatly depending on the clip and the controls you select. The standard coordinate system specifies points by
measuring the horizontal distance (x axis) and the vertical distance (y axis) from the origin. The polar coordinate system
specifies points by measuring the length of a radius from the origin and its angle from the x axis.
Interpolation
Specifies the amount of distortion. At 0% there is no distortion.
The following two options are available from the Type Of Conversion menu:
Rect To Polar
Moves pixels by using the standard x,y coordinates from each pixel as polar coordinates. For example,
an x,y coordinate of 2,3 becomes a polar coordinate with a radius of 2 and a degree of 3. Horizontal lines distort into
circles and vertical lines into radial lines.
Polar To Rect
Moves pixels by using the polar coordinates from each pixel as the standard x,y coordinates. For
example, a polar coordinate of radius 10° and 45° becomes an x,y coordinate of 10,45.
Ripple
The Ripple effect produces an undulating pattern on a clip, like ripples on the surface of a pond. The shape, severity,
and direction of the ripple pattern are adjustable, as well as the background color.
Spherize
The Spherize effect wraps the clip around a sphere, giving objects and text a three-dimensional appearance. To set the
size of the sphere, enter a Radius value from 0.1 to 2,500. To position the effect, enter horizontal or vertical values for
Center Of Sphere.
Transform
The Transform effect applies two-dimensional geometric transformations to a clip. Use the Transform effect to skew
a clip along any axis. Apply the Transform effect instead of using a clip’s fixed effects if you want to render anchor
point, position, scale, or opacity settings before other Standard effects are rendered.
Anchor Point
Specifies the point, in an x,y coordinate, around which the clip will be scaled or skewed.
Position
Specifies the location, in an x,y coordinate, of the center (anchor point) of the clip.
Scale Height
Scales height up or down as a percentage of the source clip height.
Scale Width
Scales width up or down as a percentage of the source clip width.
Uniform Scale
Scales height and width proportionately.
Skew
Specifies skew amount.
Skew Axis
The axis on which the skew is based. Changing the axis has no effect if Skew is 0.
Rotation
Specifies the number of complete rotations and degree that the clip rotates.
