The Polar Coordinates effect has the following settings:
Interpolation
Specifies the amount of distortion. At 0% there is no distortion.
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 an angle of 3 degrees. 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.
Note:
The Rect To Polar and the Polar To Rect settings are in the Type Of Conversion pop-up menu.
Ripple effect
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 effect
The Spherize effect wraps a clip around a spherical shape and is useful for giving objects and text a three-dimensional
effect. This effect has options for adjusting the size of the sphere.
Transform effect
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.
The Transform effect has the following settings:
Anchor Point
Specifies the point, in an x,y coordinate, around which the image 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.
Opacity
Specifies the degree of transparency of the image, in percentages.
Note:
In Adobe After Effects, the Transform effect includes the Shutter Angle control and Use Composition option. Both
controls are adjusted only in Adobe After Effects.
Turbulent Displace effect
The Turbulent Displace effect uses fractal noise to create turbulent distortions in an image. This effect is useful for
adding distorted movement to a clip. For example, use it to create flowing water, funhouse mirrors, and waving flags.
