Applying effects

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.
