Something changed in the camera, I can't say for certain, but I'm guessing it was the ISO, since the aperture and the shutter speed look the same the moment the moment everything comes into view.

The camera should be automatically checking everything to make sure the correct amount of light is entering. It's not uncommon for things to get stuck on the wrong setting; usually it would be because something very bright is on the scene and everything else is underexposed; but that isn't the case here. When the exposure is corrected, usually you'd see the camera searching for the correct exposure before settling on the one it's going to use; that doesn't happen here; it just completely flips.

It kinda looks like it was set to the wrong ISO manually, and then set right again right at the end. I don't know if it's possible using their equipment, since I don't have access to it. If you wanted to cut the live feed without actually cutting the feed, that would be the way to do it.
