ADOBE PREMIERE PRO CS3 345 User Guide Find Edges effect The Find Edges effect identifies the areas of the image that have significant transitions and emphasizes the edges. Edges can appear as dark lines against a white background or colored lines against a black background. If the Find Edges effect is applied, images often look like sketches or photographic negatives of the original. Invert Inverts the image after the edges are found. When Invert isn't selected, edges appear as dark lines on a white background. When Invert is selected, edges appear as bright lines on a black background. Mosaic effect The Mosaic effect fills a clip with solid-color rectangles, pixelating the original image. This effect is useful for simulating low-resolution displays and for obscuring faces. You can also animate it for a transition. Horizontal/Vertical Blocks The number of blocks in each row and column. Sharp Colors Gives each tile the color of the pixel in the center of the corresponding region in the original image. Otherwise, each tile is given the average color of the corresponding region in the original image. Replicate effect The Replicate effect divides the screen into tiles and displays the whole image in each tile. Set the number of tiles per column and row by dragging the slider. Roughen Edges effect The Roughen Edges effect roughs up the edges of a clip's alpha channel by using calculations. It gives rasterized text or graphics a naturally rough look, like that of eroded metal or typewriter text. Original image (left), with Edge Type set to Roughen (center), and with Rusty Color (right) Edge Type What kind of roughening to use. Edge Color The color to apply to the edge for Rusty Color or Roughen Color, or to the fill for Photocopy Color. Border How far, in pixels, the effect extends inward from the edge of the alpha channel. Edge Sharpness Low values create softer edges. High values create sharper edges. Fractal Influence The amount of roughening. Scale The scale of the fractal used to calculate the roughness. Stretch Width or Height The width or height of the fractal used to calculate the roughness. Offset (Turbulence) Determines the portion of the fractal shape used to create the distortion. Complexity Determines the level of detail in the roughness. Note: Increasing complexity results in longer rendering times. Reduce the Scale value rather than increasing Complexity to achieve similar results. April 1, 2008
