ADOBE PREMIERE PRO CS3 325 User Guide Resize Layer Enables the distorted image to expand past the clip's bounding box. Twirl effect The Twirl effect distorts an image by rotating a clip around its center. The image is distorted more sharply in its center than at the edges, causing a whirlpool result at extreme settings. Angle How far to twirl the image. Positive angles twirl the image clockwise; negative angles twirl it counterclockwise. For a whirlpool result, animate the angle. Twirl Radius How far the twirl extends from the twirl center. This value is a percentage of width or height of the clip, whichever is greater. A value of 50, for example, produces a twirl that extends to the edges of the clip. Wave Warp effect The Wave Warp effect produces the appearance of a wave traveling across an image. You can produce a variety of different wave shapes, including square, circular, and sine waves. The Wave Warp effect is automatically animated at a constant speed across the time range (without keyframes). To vary speeds, you need to set keyframes. Wave Type The shape of the wave. Wave Height The distance, in pixels, between wave peaks. Wave Width The size of the wave in pixels. Direction The direction the wave travels across the image. For example, a value of 225° makes the waves travel diagonally from upper right to lower left. Wave Speed The speed (in cycles per second) at which the waves travel. A negative value reverses the wave direction, and a value of 0 produces no movement. To vary wave speed over time, set this control to 0, and then set keyframes for the Phase property. Pinning Which edges to pin so that the pixels along those edges aren't displaced. Phase The point along the waveform at which a wave cycle begins. For example, 0° starts the wave at the midpoint of its downward slope, and 90° starts it at the lowest point in the trough. Antialiasing Sets the amount of anti-aliasing, or edge smoothing, to perform on the image. In many cases, lower settings produce satisfactory results; a high setting can significantly increase rendering time. GPU effects (Windows only) Page Curl effect (Windows only) Use Page Curl to simulate a page slowly turning. As the "page" turns, you see the back of the image mapped to the opposite side of the curl. The back of the image is actually a mirror image of the front. This effect is most useful as a transition where you would like to have a high-quality, textured page peel effect to reveal an underlying frame. Page Curl includes controls that function identically to the controls in the Ripple Effect (Circular). Page Curl adds the following controls not in the Ripple Effect (Circular): Angle Of Curl Specifies where on the image edge the curl begins. Curl Amount Specifies how far into the image that the curl extends. April 1, 2008
