Thanx for all your help everybody!

I think I´ll shoot it so they never cross eath other path and then draw a rough mask around them as you said 🙂

Thank you a lot!

Aaaah! That is exactly what I´m looking for!

I was just wondering… how do I use the difference key to mask out only the persons moving in my shootings? I suppose they filmed them running and climbing several of times and then masked out the persons and put the onto the backdrop.

Is there any effect that mask out the moving parts in an movie?

The camera do not have to move…
