What I'm trying to do is play three digital sources (camera, computer, and dvd player) at the same time; but I don't just want them superimposed; I want them to fight each other, hopefully creating a lot of visual noise, but with luck one of the channels would once in a while send a stronger signal, allowing for a clear picture here and there, or even a shadow of an imprint. It would be the battle of digital impulses. See what happens. The only ideas I have , being more of an analog guy than a tech wizard, would be to:
a. splice the output wires of all inputs together by hand (just twist the wires and then input this into a projector). or
b. take all the sources and put them through an audio mixer and output as one. This would obviously be my preference since the different sources would all have their own visual volume control (the audio side (live gig) will go through a different process.
But before I try this and potentially burn out several pieces of equipment, has any one tried this sort of thing? Is there a way of doing with videocube, or does there exist such a thing as a video mixer than instead of just superimposing pictures/film, allows them to mix into a free for all pixelation fight? Any ideas at all would be of great help.
