    green screen doesn't fill frame - garbage matte?

    thebedfordfox

      i have recently made a chromakey green screen by pinning material to a board.

       

      it works well for shooting - all i have to do is stand in front of the screen and not move - but there is a problem.

       

      the screen is approx 7ft tall and 4ft wide, so, while it contains all of me, it doesn't fill the frame of the camera i am shooting with.

       

      i read that the best way to deal with this is to use garbage matte with premiere elements.

       

      i have attempted to do this to eliminate everything outside the green screen.

       

      the problem is that, when i apply videomerge, the 'green' bit disappears - fine - but where the 'green' bit finished, i have a black border, which ruins everything.

       

      at least two articles i read on the internet suggested garbage matte was the solution to this problem, but the black border round the outside is killing me.

       

      help greatly appreciated.
