[jitter] Re: averaged composite of all frames of a quicktime movie

Its good that these things are possible. It gives me hope I will finish this on time. Is there a way to update the current image in a matrix without sending anything to the jit.matrix' outlet? I want to route jit.qt.grab to a jit.matrix and then bang out the current data of the matrix into jit.qt.record only when certain conditionals are met. 

Also, how can I pass every frame of a movie into jit.op for averaging all at once?
