I'm on my second a139 pro. I was sent a replacement after having video quality problems with the first one. The second one did the same thing but seemed like it was a little better. After seeing Panzer Platform's post I knew what was going on.
I did some testing on the cameras in my office at work. I would turn the light off then block the window and it would cause the image to start flickering and show static. Doing this only caused problems with 2k 60fps mode. All of the 30fps modes worked fine.
This morning on the way to work I checked and it was doing it in 4k 30fps mode. It wouldn't do it as long as I had my headlights in the center of the frame. If I tilted the lens up or down so that the light was at the top or bottom of the frame it would start flickering.
HDR on fixes it but I'm not sure that I want to use it. I've sent videos to viofo.
