Video is Flickering from Skype input

I have used Skype for about two years now, so my co-host in a different city and I can share the screen. I am running the latest version of Wirecast (9.0.1) and am running a Mac Pro Quad. Recently, the Skype input is flickering (example link below). The video is not doing this in Skype, so I have to assume its Wirecast. Any suggestions on what's going on here? In the example I give, as soon as our starter image fades out you'll see the right hand side video flickering.

  • Were you using Wirecast ScreenCapture or a second computer with Remote Desktop Presenter or NDI screen capture?

    Wirecast ScreenCapture is using the GPU. It's also possible other programs running on the same computer (and using the GPU) might be having an impact.

    You may want to reboot the computer and run a test with Wirecast ScreenCapture (it doesn't have to be with Skype and you don't need to stream live). Just look and Preview or LiveArea and see if it happens.

  • Caleb Hegg Thanks for that. Do reboot and run the suggested test to see if it happens under those circumstances.

  • Hi Craig.

    So I've run some tests and it looks like it is doing the same thing with Chrome in the window. Is there a way to fix this?

  • Caleb Hegg If it's not specific to Skype it's possible it's GPU related.
    Please post complete system specs.

  • Caleb Hegg base 2013 MacPro AMD D300 should certainly be good enough.

    Run the Apple Combo Update to 10.13.5 and see if that helps. Combo updater can sometimes fix issues that updating through the Mac App Store may not. It might help if there's a GPU driver issue.
