      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.

            Yes, but what he made 'seem' easy is, evidently, 'actually' impossible !

              I don’t know about impossible. What aspect of what you’re trying to do haven’t you been able to accomplish yet? We’re here to help.

              Best wishes,

                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.

                    I just did this and this is the result!?

                     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

                                  You have to connect the output of the effect mixer to the projector.

                                      Just wanted to post a cleaned-up image of the necessary actors and a simple example patch:

                                      Important:

                                      • The Effect Mixer actor must be set to "diff" for the "mode" input
                                      • You'll want everyone out of the view of the camera before you grab the freeze frame. (If you're using a webcam, add a Trigger Delay actor set to 10 seconds between the Keyboard Watcher actor and the Freeze actor to give yourself time to trigger the Keyboard Watcher actor and then get out of the camera's field of view).
