I'm trying to do some mixing with jit.qt.movie and jit.qt.grab (using the jit.plume object). Here is my patch. I can't seem to get it to work.The A mixer works but Mixer B doesn't.

First, you don't want 2 windows, one [jit.pwindow] and a [jit.window]. You could keep your [p fullscreen] and get rid of the [jit.pwindow].

About your question: is your "channel B" (jit.grab...) working fine by itself? You might want to add a couple of [jit.pwindow] in the path, to test that first.

I don't have a camera on my machine now, cannot test it quickly, sorry.

Channel B is working fine. I've somewhat got the mixing A-B working,but I can't use the operators and the jit.blum, e.g. B doesn't work as well as the self contain patch by itself..
