Capture firewire from a digital switcher to computer - is this possible?

Discussion in 'Amateur Video Production' started by Philip Scoggins, Jul 2, 2004.

  1. Hey, trying to answer this question...

    I'm using Vegas 4.0 , their video capture software and a Videonics MXProDV
    switcher.

    What I've been doing is capturing a show to a miniDV vcr from the firewire
    output of my switcher then taking the tape across the room to my editing
    station and playing the tape into my editor from another firewire miniDV
    vcr.

    I've decided this is wasting time and adding extra wear on the machines.

    So my question. Before I order a 25' firewire cable or move equipment
    across the control room to test my idea, can I just run the firewire from
    the switcher to the computer and make a "live" capture. Vegas' capture
    software seems to want to take over a camera to capture video so I was
    wondering do I need different capture software or will is see an switcher
    and just let me record it? It won't have and timecode since it's coming out
    of the switcher, so that might be another problem.

    Thanks for any help,

  2. So how important is it that you capture the video in real time?
    If your computer crashes or you forgot to make enough disk space,
    can you yell "CUT!" and pick up from the previous shot 10 minutes
    later? I've never had anything like that happen with a VCR. I
    wouldn't dream of doing this with a public, live show, but then
    I'm the kind of person who always wears a seatbelt, etc.

  3. It's short segments. Approx 2-5 minutes each and would be no problem to let
    them run the last take again it the computer crashed.

    So... does anyone know if this is possible? I talked to a tech at videonics
    yesterday who told me it was impossible and that no switcher currently has
    this capability... But it sounds like something that someone would have
    figured out how to accomplish.

  4. I have no idea why this is not trivial. You could just plug it
    in and try it. (That is certainly what I would do.)

    You may have to use capture software that doesn't assume
    that it has a camcorder to control. There seem to be several
    free or low-cost candidates for that.

    Dunno why it would have anything to do with any "capability
    of the switcher"? A Firewire/DV stream is a Firewire/DV
    stream whether it is coming from a switcher or from a VCR.

  5. Their tech said that they strip off some of the data that the capture
    software is going to want to see... timecode and others things that he
    didn't specify.

    The editor is across the control room from the switcher and I didn't
    want to unhook either and move to test. I figured someone here would
    have tried this before.
