Make an image with black-to-white gradient that repeats three or four times. Apply a Levels filter with slight wiggle() expressions for all the values. Maybe also wiggle it up and down. Precomp that and use it as a displacement map.

Thanks for replying to my post.

Could you maybe give me a more detailed description. I’m rather new to After Effects and it’s kind of hard to understand what you meen.

Thanks

This explains how to use displacement maps, which is a good way to distort the image.

But if the distortion is perfectly still, it won’t look quite like reall fast-forwarding. A good way to make it shake is to apply a wiggle() expression.

This is a good intro to expressions. In there is a bit on wiggle()
