Sony a7sII, Black Magic Intensity Shuttle, and iMac 27" (2017 model)

I can't get Wirecast to read my video input.  The black magic intensity shuttle reads the input wire from the camera and is working properly.  Wirecast reads my camera and lets me add it as a layer, but I still get a black screen???

  • I'd like to help but I need more technical information.

    Make sure you've updated your OS to 10.13.2 Please Confirm
    Wirecast should be version 8.2 Please Confirm
    Blackmagic Driver should be 10.9.7 Please Confirm
    Then test in Blackmagic Media Express to make sure it sees the video from the camera.

    Reboot the computer with camera on.
    Open Wirecast and create the shot and then check the settings in the shot's System Device Properties. An issue with those settings could be a cause.

  • I don't know what this means or if it makes a difference.  Do I have to buy the pro version for this to work?

     Sorry but you haven't mentioned about testing in Media Express.
    Also you have video format set to 1080p24 and pixel format a YCbCr.
    Do you know those are correct.

     If you have the device designated for output it will not work for input. Please make sure you aren't demoing a pro feature.

    You need to follow through and check in Media Express then reboot and check your settings in Wirecast. I don't know want to recommend because the settings really depend on your choices.

    You don't have Automatically Detect Input Format for example.
    I have a different Blackmagic Device, a Mini Recorder but it works the same way because it's the same driver.

  • Gerritt Bake Confirm you're using Wirecast 8.2
    Make sure you see video in Blackmagic Media Express to know your camera and device are working. Please Confirm.

    You need to make sure you've selected the correct Video Format and Pixel Format in Capture Card Properties since you don't have Automatically Detect. If they are incorrect you will see black.

  • Yes I have 8.2

    What pixel format should I be at?  I have everything on the camera and black magic set to 1080p24

  • Gerritt Bake Leaving Pixel Format alone for the moment, cycle through Video Format. Often p24 is actually carried in an interlaced stream. Try i59.94 but test others as well. Keep in mind also that the camera recording format is not necessarily what the camera is sending the Shuttle.

    Hi, did you guys figure out the solution? I have the exact same issue and need to live stream for a client in 48hrs. I'm using sony a7sii and can't seem to get a signal into wirecast.  Everything worked fine a few months ago with Canon 5Diii, but hurricane harvey destroyed all our equipment and now we're using sony cameras. Any help is appreciated, thanks!

  • Jud Johnson perhaps it was resolved given there was no post back.
    Please update to Blackmagic Driver 10.9.10 and test in Blackmagic Media Express to confirm the input is working outside of Wirecast.

  • Never mind, i figured it out. With the a7sii it has to be set to 24/1080i.

  • Jud Johnson Good to hear you've got it working. 

    Different video input devices may have varying specs. Some accept 60p for example and other don't. Some require 24p or 30p to be carried on interlaced (PsF).
