can anyone tell me what's the easiest way to create this effect with images and movies?

thanks =)

It looks pretty simple.

1. Duplicate your desired video clip and place on a new layer.
2. Mirror the footage to reverse it. Then place at the appropriate place so that "seams" line up. (Skew & distort footage as needed)
3. Apply a gradient layer mask and play with opacity until you get the desired effect.

I've seen that same screenshot somewhere, I think it was from the "fxfactory" plugins, search for it at apple.com downloads.

I was looking for an effect to solve it, but i'll try both methods. thanks :)
