Do you see any large power lines in the video?, I don't.
What *can* you see in the video?
[Semi-rhetorical question. I think I know what you see and that's only what you want to see. But I've got a cold beer beside me and 5 mins to spare before dinner, so let's do this anyway and spell out the objective observer's case]
Because of the flat topology and openness of the landscape there's no good frame of reference for the distances involved, or for the size of the vegetation on the horizon. They might be large shrubs, or they could be trees. If the latter, then the distance is probably several hundred meters or more.
Regular 11kv or 33kv distribution line conductors are probably in the order of an inch in diameter, maximum. The camera would no more see those against a dark background at a distance of several hundred meters than it would how many fingers I was holding up at the same distance. But if I were running my plasma cutter or MIG welder you'd see the arc from that for sure. The same kind of lines wouldn't be on transmission towers just regular poles and again, at that distance you may not easily see those against the horizon either.
And no, they wouldn't have to be located in the field and probably wouldn't be in your country. The view is across a very flat area and therefore could easily have line of sight over a road which itself isn't visible in the video because of the camera's small angle of declination relative to it.
That's all before we consider the prevailing 'gloomy' lighting conditions (looks like storm clouds, rain, possibly mist). Oh, and the massive plasma discharge which must be affecting the camera's exposure / white balance/ dynamic range / whatever.
Am I saying that there ARE powerlines in that location? No, absolutely not what I'm saying.
I AM saying that we (and that includes you) cannot reasonably exclude the possibility that there are *on the basis of these images alone*. The image quality and information content of what has been presented is insufficient. Anything else is just confirmation bias and a personal need for this to be a rare and exotic event, rather than a genuine desire to understand what it really was.
