Thank you for your answear. I know about 3d source alpha, but this is not enough when you have to use this effect in many frames. What I want to do is newspaper effect. I recorded newspaper when I change page, and I have picture JPG witch one I want built to this newspaper. I hope you know what I mean. When you changing page this picture change with newspaper as well. 3d source alpha is not good tool to make this operation, I think.
