Re: Pixelization effect by Kevin Camp on Jan 16, 2012 at 6:05:15 pm
a quick way would be to use an existing image or try something like fractal noise to generate a texture. then add the mosaic effect to pixelate it and the threshold effect to make a black and white matte.
animating the threshold 'level' can create the reveal.
you can use that as a track matte for another layer, or an effect like unmult or set channels (or similar) to key the black out and then add the fill effect to fill the alpha with a color.
