      @woland Thanks! Yes this is what I used to do - which is fine - but you get all the background along with the dancer.

      I need to differentiate the dancer from the background which is why it seems to make sense to take a freeze shot of background WITHOUT dancer and then Izzy can subtract what remains UNCHANGED from the moving body! Graham Thorne showed me this freeze/eyes etc routine but I can't get it to work as I have said.

      I use the web cam recommended in Izzy manual - I think its an HP one.

            Hi.

            Might sound obvious but you have to take the background image (by pressing P) with your body out of the live feed video.

            Also remove the Live feed video out from the projector and connect it to the Effect Mixer Video out - you will see the result.

                  As I wrote in my post above I don't think you will get what you want this way. Next to that, if you leave the setting "additive" in the blend mode of the projector it will definitely not work as you want.

                    You may find you can clean away the background (somewhat) by adding a threshold actor. 
                    Additionally, a Contrast actor, may allow you to 'tune out' the background shades as well.
                    Its possible (depends on what you really want) that the TT Edge Detect glsl shader (requires downloading the bundle from the Plugins section) may provide some of what you want.

                              I guess what he wants to do is isolate a person/dancer with a normal web camera and put him over a background video/picture. And to be honest with that setup it will be more a tinkery unsatisfying solution.

                                   This isnt working because you have two projectors; one clean feed from the live feed and one from the background subtraction.

                                  I have just opened your 'graham.izz' patch and it worked first time.

                                  Open the patch - step out of the way of the camera - press P to take a still image. Then move into the frame.

                                    Well its not a clear isolation from the background but some fancy difference effect on the person. But maybe this is what he is looking for. 

                                    And still to say with a camera set to automatic you will not have a clean cut out if it sets the blend to a different value.

                                          Hi Vidasonik, I am definitely not a pro, but what helps me is to create tidy patches. It helps seeing, what you are actually patching...In your case You would notice, that your VideoInWatcher is connected directly to the projector as sculpture earlier in this threat pointed out . Somehow your calculation "got lost"... Kind regards, Tom
