Use Accentuated Offset Wiggle Expression to Create Z-depth Ripple
Hi,
I have a grayscale z-depth image that I am using the Extract effect on with this expression – (index-1)*5;
Thus stepping the Extract’s black point up by a multiple of 5 on every duplication of the layer, meaning that it will take 51 layers to reach max black point (255).
I want each duplicate to follow the position value created by audio keyframes, but these position values need to divide by 0.01 upon each duplication.
The desired effect will look like a sound ripple is passing from the camera outwards into the environment and dissipating.
So far this is what I have as my expression but it’s not working:
I think there needs to be some kind of time offset for the expression too so it really creates that wave effect

yeah, you need a time offset, not multiplying the amount. try using the valueAtTime like this:
value + thisComp.Layer("Audio Amplitude").effect("Both Channels")("Slider").valueAtTime(time - (index-1)/100)
