    Keying out black background but keeping black image

    Greenboks Level 1

      Dear anybody

      How can I show black smoke on my film, when the background of the clip that I got the black smoke from is also black? It is from action essentials pack 2. If I use "screen" on blending mode, then I see nothing. How can I get rid of the black background and still show the black smoke?

       

      ALSO, if I have a blue background or green background on my footage, how to get rid of that so that the image is still there?

       

      Any help is much appreciated.
