Re: syncing 2 16mm projectors

You should be able to put the two video streams together side by side
into one quicktime movie and then just let quicktime play it back.
You may not be able to go fullscreen without it constricting itself
to one screen, but if you pull the window out to cover both screens,
you should be able to cover most of both of the screens with video.
What is not video should be pretty easy to mask out with something
like black wrap or even some cardboard (though be careful if it's a
really hot projector). I'm also guessing that some software made
specifically for live video mixing might be able to do the two-
screens-two-videos thing, but short of that or Max/MSP or something
that is on the verge of getting really technical, nothing comes to mind.

Hope this helps!
