Scren Capture black flashes

We have been recording talks with slides in Wirecast Pro from Zoom for a year now, but for the last couple of months have started to experience 1-2 frame black flashes in Screen Capture, details in the image.  Layer below Screen Capture is a Blackmagic Ultrastudio Mini Recorder, HDMI or HD-SDI input, via Blackmagic Desktop Video v.12.0.  The CPU typically shows between 8% and 25% during recording.  The flashes vary from barely noticeable once or twice during a recording (see top left) to rendering the recording unusable.  I am currently testing standardising the frame rate at 25 everywhere (UK based).  Any other suggestions?

  • Based on the information in picture attached is you Video Display Rate is set to 30fps even though everything else is 25fps.

    Please set that to 25fps. Start a new document and only do a screen capture of Zoom in a new document and see if the issue happens.
