A & B Midpoint The midpoint specifies the balance between the two colors used in the gradient. Lower percentages use
less of the A color. Higher percentages use less of the B color.
Color A, Color B The color of the glow if you choose A & B Colors for Glow Colors.
Glow Dimensions Specifies whether the glow is horizontal, vertical, or both.
Mosaic effect
The Mosaic effect fills a layer 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. At Best quality, the
edges of the rectangles are anti-aliased.
This effect works with 8-bpc and 16-bpc color.
Original (left), and with effect applied (right)
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.
Motion Tile effect
The Motion Tile effect replicates the source image across the output image. When you change the placement of the
tiles, it uses motion blur to accentuate the movement if motion blur is enabled.
This effect works with 8-bpc color.
Carl Larsen provides a tutorial on the Creative COW website that shows how to use the Motion Tile effect to create a
whip-pan transition between two layers.
Tile Center The center of the main tile.
Tile Width, Tile Height Dimensions of tiles as a percentage of the input layer dimensions.
Output Width, Output Height Dimensions of the output image as a percentage of the input layer dimensions.
Mirror Edges Flips adjacent tiles to form mirror images. If Phase is set to 0, selecting this option causes the edges of
the layer to be mirrored with the surrounding tiles.
Phase The horizontal or vertical offset of the tiles.
Horizontal Phase Shift Offsets tiles horizontally instead of vertically.
