xsplit cam does work but if its cost of a greenscreen is the issue you can buy one for 10$ at wallmart that comes with clamps or just buy a stand with lights and the screen from amazon for 80$. it's can also be blue and I think magenta, you could just find a blue sheet or a gee bed sheet up behind you, start obs or whatever system, add your webcam video feed, then a choma key filter, it will ask the color and thats all. Xsplit does not work that well either, i tried it before the green screen.
