    Hi y’all
    First of all i want to say… This site rocks!!! It helped me alot.
    Now for my question.
    I want to add an speciffic effect to my film project. It’s looks like when your VCR is tracking the image. The distortion in the image is what I’m looking for.
    I’m using Avid Xpress pro hd 5.0 to edit the footage, and I’ve got basic knowledge of After Effects.
    All help is appriciated.
    Thanks

    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()
