First off, I believe you need to isolate your actor on one layer. Shooting in front of a greenscreen would be best, but you could also do this using masks and a lot of painstaking work. Actually, now that I think about it, for a displacement effect you could film him in front of any evenly colored background, and it would work ok, but a keyed out or masked out actor will work best. Then place this layer over the top of your background plate.

Then you set the Composite mode (in the timeline) on the layer with your predator to Displacement. Use the sliders in the displacement controls to adjust the subtlety of the effect to your liking.

I think that's it.

NOTE: Even with a solid background still behind the actor in the shot, you can still get the desired effect with displacement. However, the very edges of the frame might get ugly lines in them as a result. If you use properly keyed footage of your actor, you will not have this problem. Displacement works on color info, so any variation in colors in the background of your displaced layer will cause displacement ripples in the final shot.

Sure enough, I searched the forums, and found this:

http://fxhome.com/forums/viewtopic.php?t=22716

There is a link in there to a video tutorial for the effect. However, he uses a technique not requiring a displacement map. Elab's displacement map will make it even easier.

i was about to link you guys to my tutorial, bbut axeman beat me to it smile

I really dont know, but can you use the displacement map feature in effectslab for this kind of thing? i thought you needed to have it in clab. so it would requre clab pro not elab pro.

anyhow, if you can use a displacment map, use it. my way is just the cheaper way.

still, i hope my tutorial can be of some use to people out there.

good luck,
SGB

I was in the process of replying in this topic, but unfortunately I was interrupted, and could not finish the reply, nor save the message. Conveniently, Axeman has covered the majority of what had been covered in my post.

One quick note that may still need to be added, however, is that EffectsLab does not have a displacement map feature that is intended for this purpose. The displacement map function in EffectsLab is intended only for the effects engines, and can only be applied to the effects engines, and not source footage.

Compositelab DV does not have a displacement map function for any of the objects in the track listing. The best solution for doing this effect with ease, and speed, would be to use CompositeLab Pro, or VisionLab HD. Shoot the actor, or object, in front of a green screen, just as Axeman suggested, and then use one of those programs displacement map functions to create the desired effect.

Edit: That is correct SGB. You must have either the pro version of CompositeLab, or VisionLab HD. Although I have not tried it, your tutorial seems to be a fine alternative to this, and I am sure it will help many.

Have a good day.
Wizard.
