  • Sounds like you are using the Wirecast screen capture shot. Are you using monitor, window or game capture type? What application are you trying to capture? What model Mac are you using?

  • I'm using monitor capture. Please refer attached my mac Specs. it is iMac (Retina 5K, 27-inch, 2017) model

  • The flickering also happens to NDI source (Newblue Titler Live). Please refer attached clip.

      Please look at Live Broadcast Area only and do a local Disk Recording with MOV preset.

      The various Preview windows may vary their display for some technical reasons. Output in Live Broadcast Area should be the primary concern.

      Radha Krishna Ganesna That looks like a NewBlueFX Titler Live issue. That video doesn't show Wirecast.

      Please check Titler Live NDI out using Newtek NDI Video Monitor.

  • Hi Craig, You can refer the same video screen capture in the previous attached video. the flicker is only in Wirecast and not in Titler Live. 

    You can refer the following link.. has many screen capture flashes in the whole program. however, you just check the following link. in a second, you can find one. 

    What i say is, it is not about just NDI source and screen capture source too.

    if you are not able to pin-point the issue, just share me how to uninstall Wirecast 100% from my system (macOS 11.5) I will re-install and try.

     macOS 11.5 is beta. We haven't finished compatibility. Please only use Wirecast 14.2.1 in macOS 11.4 Big Sur or Catalina macOS 10.5

    It's hard to know all the sources in the video you show but this may not be related to screen capture. I can't really tell from that video.

    I'd suggest you create a New Blank Document and test with the iMac's built-in Webcam  ONLY and see how it looks in the Live Broadcast Area and test in macOS 11.4, not 11.5

  • I have re-installed my OS from scratch and tested. there is no screen-flickering. However, there is flickering for NDI source (Titler Live). 

    I had the same issue earlier also with  macOS 11.4 & Wirecast 14.2.1. I thought, it works if I upgrade, there is no difference.

    Please test Titler Live in Newtek Video Monitor (please download NDI 5 Tools for Mac).
    This may confirm the issue in Titler Live.
    Please test another NDI Source (NDI Scan Convertor for example) in both Newtek Video Monitor and Wirecast 14.2.1 This may confirm any issues with NDI handlling.
