flickering

[treasuredmemoriesimaging]

I own two ultrasound studios and I capture the video from the ultrasound machine through a video capture card with OBS software and I am getting flicker I don't know what I have wrong in my settings but wondered if you thought you might be able to help me. I have used it for 3 years and just now started this flickering issue.

You need to figure out. Is it obs, capture hardware, cable, ultrasound output.

Did you upgrade OBS lately? If so, roll back to the last know good version.
Is this happening at both studios or just at one installation? Need to find the exact reason.
Have you tested video output on an external monitor without the mac/obs inline? Do this to rule out the ultrasound gear.
The only time Ive seen flickering or dropout was due to a bad cable.
Is there another capture / viewer app that came with your capture card that you can test to see if the flicker is happening there?

Sharing your specs and more details on whats happening where and when could be helpful.

Thank you so much for answering.
I am coming out of the ultrasound machine to a hdmi splitter. The splitter then goes to my TV and to my video capture card to my mac.
I have taken out the splitter and directly gone into the video capture card to the mac. Same problem. I have even got a new video capture card. Same problem. I have changed cords same problem. The only thing I have not done is gone to an older version of OBS. It is happening at both of my studios. It has to be inside the OBS software. I thought maybe the frame rate on the ultrasound machines was lower so there was a conflict with the software but it doesn't seem to matter if I change any of the settings.
