Wirecast Gear and 4K...

We have the HDMI version of Gear - am I right in thinking I can attach a 4k camera (or two), create a 1080 'canvas' and get lots of digital zoomabilty on the 4k HDMI feed(s) and spit out a 1080p stream to my destination?

  • The HDMI version of Gear uses the Magewell ProCapture Quad card which are 2k inputs. 2048×2160 pixels

  • CraigS Well, that's very disappointing.

  • CraigS Is there anything I can plug in to the USB3 ports to allow for 4K streaming?

     Admittedly so and I've brought it up with the developers. I don't think there are 4x4 HDMI 4k cards yet from the major reliable card manufactures. Most have single input 4k cards but even including one of those could be valuable.

     Magewell and Epiphan both make HDMI 4k to USB3 devices. They should work with Wirecast although we haven't tested yet. Both are plug and play (no driver needed I believe).

  • CraigS I can't seem to find the 4K Epiphan device, and the Magewell one is marked as 'coming soon' on their site (and doesn't appear to carry the audio through the HDMI cable). I have found an Inogeni one though: https://inogeni.com/4k-usb3-0/

    Any idea how many of these the Gear box will support? Does each USB3 port need to be on a separate bus to support more than one?

    Yes the Magewell device isn't ready. I saw a prototype. They're doing a slight redesign for better heat dispersion and then they have to get FCC approval.

    I've heard of the inogeni devices. I'd love to see user reports.

     Just a guess but I imagine these devices use significant bus bandwidth so likely just one on a bus.

     And do you know what the bus set up is of the USB3 ports on Wirecast Gear?

     I have a contact at Holden here in the UK and they're going to see if I can get one of the Inogeni devices to test drive.

  • CraigS Ah, not the news I was hoping for... could you find out for sure for me please? There are six all together and the four on the back are in two groups of two, so there might be a chance that they are on two separate buses??

  • RuffKut I'll check and confirm for you.

  •   RuffKut You could hook up some USB devices (webcams) and check the number of buses in Wirecast to test while I get confirmation. This not a Gear (it's a Mac of course) but I thought I'd show you how to check USB bus assignments.

  • CraigS The SDI versions of Wirecast Gear dont allow 4K streaming either, do they? Would the Magewell Pro Capture SDI 4K Plus card work with Wirecast Gear?

  • Ian McCullen Since the capture cards aren't user serviceable we'd have to consider making a Gear with the Magewell Pro Capture SDI 4K Plus cards.
    Magewell does list the card as compatible with Wirecast so it is possible.
    LP will let the developers know of your interest.
