How can I mask out the non-moving background of my video?
-
I am using the Video In Watcher actor and my video feed is of a room with dancers. I want to isolate the moving parts of the video (the dancers) so that when I layer it over a background on the stage it will be like bluescreen effect with the dancers over the background. It's impractical in my case to have an actual colored background so I was thinking that since its a fixed camera and the dancers are the only thing moving, there should be an actor that picks out just the moving parts and masks out the rest (makes it transparent). Is this possible?

There is a method described here by @mark : : webcam-background-removal

@bonemap That method isn't going to work with me since as the post mentions, if the background moves even a pixel or the lighting changes it will stop working until you can take another empty room capture. Using the difference actor you can get a sort of ghost like set of edges that move with the people, but I'm not sure how to enhance those edges and clean them up to improve it.

I don't think you're going to be able to achieve what you want, not just in Isadora but in any 'affordable' system, if the 'difference' method isn't working for you.
Any method for isolating one thing from another relies of a way to do that isolation. Greenscreen is one way, IR masking is another, using a Depth Camera is a third. So if you can't use any of these, how else can you isolate the dancers from the background?
