Transparent trail
How could I achieve a speed trail effect like the one is this picture? Could I use AE and animate it to follow the actor?

Thanks

Are you shooting a foreground plate and a background plate?
if so you could posterize the foreground plate to make trailing copies.
then you could distort the trails using caustic maps or ripple or whatever you want to taste to mess up the image. Then you could transfer mode and change the opacity to achieve the desired distortion. -
You could do this with dsiplacement maps, or the effect called caustics – these effects displace the pixels to create distortion.
However, you need something to generate the displacement – if you film you actor on a green screen, you can use an effect like echo time to be the source of that distortion, or you could trail particles behind your actor and use that as the source of the distortion.
It would probably look better if you used the actor on alpha (green screened) as you get the exact shape, and you could also use it to generatye a faint motion trail to mix in with the distortion which would look good.
It’s not a “simple” effect, but if you’ve planned ahead for this, you can do it easily enough.
