It's called SCIENCE. Rolling shutter artifact effects videos, yes. Like the one taken in NYC with that devil beating his wife and lightning shooting through it.
Many stills come from videos. You don't have to edit them to get that effect.
It's a fucking lightning bolt in a sun shaft while it's raining. Happens in the south all the time. You Yankees are getting a taste of shitty weather. Congrats; it's been happening since long before Q attributed it to the authors of the Bible.
