Without being too picky, I don't think that the picture you've posted is a terribly good effect. Good "tracking" blurs exhibit a kind of "snap", where you have a trailing blur that essentially goes from zero opacity to %100 opacity at the point where the present image is. . .in other words, you "build up" intensity, giving the sense of something rushing towards the viewer. Try blurring, and multi-replicating your source image, and overlaying. . .experiment till you get it right. Andromeda had a filter called "Velociraptor" that did exactly this effect. ..but I agree with the above. . .there's really no reason to use a plug in for something like this; you'll learn more by fooling around with it until it suits you
