This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

I'm guessing this is a rolling shutter effect since the lines were always horizontal wrt the screen but can't really explain it. Shutter speed is 1/1500s. The lines appear on other shutter speeds too but fade away as you approach 1s. They seemed most noticeable at factors of 1/50s or 1/750s.

I'm guessing that you're seeing the result of the interior lighting being PWM modulated combined with the rolling shutter.

Pulse Width Modulation modulated?
