I was streaming tonight using OBS Studio for the first time, and I had an issue with the Retro deinterlace, top field first setting. It was very jittery, which doesn't happen with the original OBS which I had been using to stream until now. I've attached the log file, and the link to my stream VOD tonight where you should see the problem happening consistently throughout the video.
