This photo I took on an airplane

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. Here's a screen video: https://quickshare.samsungcloud.com/xc6hikOCglkz

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?

Looks like the window from inside of an airplane.

Maybe the engine noise hit a resonance frequency of the camera chip - most cameras during operation suspends part of the camera in magnetic field, which also allows for focus and stabilization.

I guess that's a thing that could happen but why would that produce lines?
