Well, what are you trying to understand exactly?

To do the 'invisable' effect such as seen in the commercial, all you need to do is shoot the person against a greenscreen. Then, import the videoclip into VisionLab and put it on your timeline. Take away the greenscreen. Then, go in the 'composite' section of the video



and select 'Displacement Map'.



You actor will then be completely invisible. You will need to import the background picture/footage that you will use in VisionLab, and put it on the timeline below your invisible actor.



The actor will now appear as completely invisible.

I hope this helps you!

And they were dead sexy.

And for the greenscreen, it's really no big deal, as Rody also said. Especially with VisionLab's amazingly powerful tools, you can get the crappiest greenscreen to work, well, not perfectly, but close. razz

Still one more question about the predator effect. How can I time displasement map to the right point? I mean, I don't want it to begin exactly when the video starts, I want the predatot effect to appear like in the middle of the video..Hope you understand.

Hi,

I didn't use a greenscreen, but i did use two video layers and a single mask on the "predator" layer.
The mask masked out all the background and then i applied a displacement map.

I did rush the effect, but i think it worked out quite well.

I have just added a very crude guide on how to do this... hope it points you in the right direction. I will try and find the time to do a better quality and more thorough version.
