Hi J,
thks for the message. Yes! I am still stuck with this..trying to isolate them (the dancers) so I can put another background underneath them, I need them to be transparent, isolating them form the background.

I have done the cartoon effect to try and isolate them, then tried the rotobrush to get an isolated mask of them, but is not working very well…her dress is almost exactly the same color as the background…trying to avoid to rotoscope the whole scene, it will take me forever 🙁

more ideas?
