How do you make an animated background control a foreground image?
Hi Everyone,
I think I might be asking too much fron AE but here’s my question:
I have a water background that I made with fractal noise which is animated so it loops. Then I have a logo over the “water” which would look a lot better if it looked like it was floating on the water and following the random “ripples” created by the fractal noaise effect. So my question is can you use te fractal noise plugin to contol a ripple effect (or something that would have a similar effect) or is there anyway that this can be faked? If you need some picture if you think that would help i’ll try to post some.
Thanks,
Paul
PS I’m using AE 6 someday we’ll upgrade.

Hi Paul,
Aharon Rabinowitz did an awesome three-part tutorial on “Displacement Maps”, which is probably what you want to use, if I understand the effect you’re trying to achieve. I am on 6.5 and 7 so I’m not sure if this was included in AE 6.
Basically it involves 1.) corner pinning the logo (or text) to get the perspective, 2.) dropping the opacity and changing the blending mode to color correct, and 3.) finally (most important) applying the Displacement Map filter to distort the logo where the ripples are.
There’s a lot more to it than that but you get the idea. Go here and scroll down near the bottom for the links to each of the 3 parts:

This is wondrously easy, and it looks great to boot! Put your water layer on the bottom, put your logo over the top of it, and apply a Displacement Map effect to the logo layer, telling it to use the water layer below it for displacment. Then simply adjust the parameters to your liking.If your water layer is at an angle to the camera, rather than straight on, it helps the realism to add either a corner pin, or to make the logo layer 3D and angle it so as to match the angle of the water. Good luck! For additional realism, you may want to drop the transparency of your logo slightly (90 – 95% usually looks good), or even play around with modes until you get what you like.

you can find the full size (800×600) version by clicking on my head above. It will take you to a bunch of video tutorials, including those 3.

Thanks Guys! It really does look awesome. I’ll have to keep this effect in mind for other projects. I’ve only been using AE for about 10 months now and creative cow has been a huge help. Hopefully I’ll be able to start helping people on here so I can give back to the community.
Thanks,
Paul
