Recreating Corruption

[Kevin Camp]

displacement map would do this, but you’ll need to create a comp with horizontal bands of black and white to use as a ‘displacement map layer’ for the effect.

i think you could create that quickly by adding a new layer to your comp, make it black and add the checker board effect. set the effect to get size from ‘corner pin’ and set the corner pins to give you horizontal bands. then set the blending mode in the effect to ‘normal’.

precomp (layer>pre-compose) that layer, moving all attributes to the new comp (you don’t need to open that comp).

add the displacement map effect to the footage layer. choose the band layer as the ‘displacement map layer’ and set the other settings as needed.

awesome, can’t wait to try it, thanks!

What I would try, though this is more manual, is duplicating the layer, shifting the position, and masking it. This will give you the bands. Beyond that, you can enable time-remapping to “stutter” the bands (since that is frequently what happens with dirty heads) and keyframe the opacity of the banded layer (toggle-hold, so they will jump between 0 and 100%)

Playing around with keyframes, positions of the maskes, etc, will go a long way to “selling” the effect.

can you go through the “stuttering” process in a little more detail, what process within time remapping do you do and what is this toggling-hold thingy.

Sorry about the amateur questions i just dont really use this part of the program that much, but i want to 😉

Many thanks!

To enable time-remapping, select your layer and go to Layer:Time:Enable Time Remapping. This will show a new property in your timeline to keyframe the timing of the layer.

Toggle-hold keyframes hold the value until another keyframe comes up. As an example, if you have two normal keyframes for opacity, 0 & 100%, the layer will slowly fade up. With toggle hold keyframes, the opacity will remain at 0% until it gets to the 100% keyframe.

To use toggle-hold keyframes, right-click on the keyframe in the timeline and select “Toggle Hold Keyframe.” I’d suggest using these on the time-remapping too, as it will easily allow you to do freeze frames & stuttering.
