Any thoughts on what may have caused this to happen? Sensor windowed to 5.7k since you can only shoot 50fps if you're using the full 6k sensor when shooting in 1080. These particular clips were shot at 1920x1080 in 60/23.98 fps. Any thoughts? Here is a link where you can download one of the clips to see what I am talking about. I've tried replicating the noise at home in low light, shifting through almost all of the ISO settings and I haven't been able to replicate the noise pattern that showed up here. I looked at a lot of the dance footage I shot later that night, where there was even less light, and there is no patterning on that footage.

But it seems that this noise patterning exists on all of the footage from the shoot with the couple in this area.

We were behind schedule during this shoot and moving very quickly, so I honestly can't tell you what ISO I was shooting at during this shot.
