speed effect

well, what you could do is to apply the scan lines first (you won't get around that). Now you select each line individually, and shift them around a little (which means a few pixels to the left and right). And after that, you can optionally add black spots in the sprites, but that isn't really necessarily (and it should only be applied at the edges of the character, since it looks weird otherwise). Hope that helps
