As for your first paragraph, yes that is exactly my point in my response just a few comments up...the OP said it was an xiaomi webcam (not sure the exact model) and it is most definitely digital and fairly inexpensive, which means that you are correct it is most likely fully automatic. Your point about WB is. correct, and in addition, the ISO is also fully AUTO. Which means that as it becomes darker abruptly during the outage, the camera is gonna struggle to adjust its settings, resulting in both potential changes in color (from WB) and exposure (from auto ISO) totally normal stuff but misleading if you are trying to use the results as evidence of anything unusual.
That was my thinking as well. Something flashing in the distance at that point is a little too convoluted for my taste, although it could happen.
Completely debunking the video requires an expert in optics, an expert in video surveillance equipment, and an expert in electrical engineering, but it only takes one deluded maniac to "prove" it is aliens. An annoying feature of such claims.
But the people in the thread have done a pretty good job of explaining all of the phenomena.
