    so my question is,

    -what are the best cams for this app?

    -does such an interface exist?

    -can i control the the different projectors in real time with a pc?

    end result,i want to have many cameras set up and be able to switch whats being played on the different projectors in realtime.

    Hi Fred,

    I can't actually see the picture - it's a bit too small I'm afraid!

    From your second post, however, I'm gathering that you want to have several cameras set up, have their video (and audio?) fed to a central computer, which can act as a video mixer, outputting different signals to different outputs, in your case projectors.

    If so, yes, it's entirely feasible - however, it may be either cheap, but hard to actually do, or, expensive, and easy to do.

    I won't write any more in case I'm totally wrong with my assumption, but write back and let me know.

    i just need the video as it will be used for live performance.kinda like a jumbotron type setup.

    Ok well in that case, yes it certainly can be done:

    Cheap way:

    Use existing computer with as many camera inputs as possible (usually FireWire), and as many outputs as you need (VGA?)

    You then need software to handle the mixing part - VidBlaster is something I've played around with before, but never used properly.

    Advantages of this setup:
    - easy to get setup
    - should work for most people

    - need a very powerful computer to handle many cameras and outputs
    - may need to upgrade computer with extra input cards/output cards.
    - need good knowledge of upgrading computers to be able to know what card will work with your system.

    Expensive way:

    Gets dedicated mobile studio system or at the least vision mixer.

    - easy to use
    - broadcast quality with less possible lag than cheap way
    - all the pro advantages of a vision mixer

    - very expensive
    - can be complicated to setup without prior knowledge
    - if something goes wrong it's more difficult to troubleshoot

    Just noticed your picture is bigger.

    Bullet camera - presume this is going to be some sort of sporting activity, perhaps mountain biking or something?

    If so then it's going to be more expensive - you'll need transmitters and receivers, which will cover the ground you need. The mixing is the same as before, but it's just getting that initial input.

    well heres what my end goal is:

    im going to set up maybe ten cameras on a stage during a concert.

    i want to display the camera angles live feed using the two projectors.

    im assuming the bullet cameras are cheaper because i will be using the pc as a DVR instead of ten individual cams.

    from running sound, i assume the bullet cams will feed into a interface that has video outs that can be controlled by the pc?

    Bullet Cams>>>Interface>>>PC>>>Interface>>>Projectors

    iam i even close on this one?
