Live Capture Issues/Advice



  • I'm looking for some help with hardware selection. This is what I'm trying to do:

    Use two, 4 camera security systems in isadora to project live video feeds. I have:
    two Swann 4 channel Security systems with VGA and BNC video outs.
    Two Elgato video capture devices.
    One (possibly could use two) MacBook Pro 2013 running 10.8.5.
    Isadora up to date with video upgrade.
    I think, based on attempts and searching the forum, that the Elgato video capture device will not work.
    Is this correct? If not, What will? 
    My Security systems are accessible via network, but I haven't been able to set that up yet. If I were to do that, could I get the feed into isadora via Syphon?
    Do I need another capture device? it seems to be harder to find affordable, mac compatible capture devices. Is there a pc device that would do this more inexpensively, if I could get a pc?
    Furthermore, is it even possible to use two systems on one computer or do I need to look into a master/slave setup?
    Your help is very much appreciated.
    Happy halloween,
    Duncan


  • Looking aroind, I think the Xlr8 xtraview should work because it can record directly into QuickTime. Thoughts? I don't think I can use the black magic device because I only have one thunderbolt port and I'm using it to output to the triple head. Is this correct? Thanks, Duncan

  • You MBP has USB3 ports. BlackMagic makes devises for USB3 as well

    Sorry, I am not an expert on newer MBPs and BM products. My best experience is with Matrox MXO2. 
    Also I have had good luck with XLR8 type USB2 video grabbers. Namely EasyCap.

    There is one with 4 analog inputs, but I have not tried it.

    the BM usb3 device was great for a show I did with a Imac (sorry don't know the generation, but fairly new). I was able to move the usb3 BM device between Mac and PC without issue (once the updated drivers were installed).

    I am very happy with my BM Intensity shuttle USB3. Very stable and reliable.



  • Thanks for the help. I went with the xlr8 xtrwview and it works pretty well. Occasionally it gives a yellow screen, which is supposed to mean that its not getting enough USB power, but I think I can fix that with a usb power booster. I moved my triple head power to a hub, and that has helped some. Hopefully I can determine what causes the feed loss. Thanks again!
