White lines on video

[dadooo]

Hi guys,
could you please tell me what causes those white lines across the video?
It's barely visible but if you look very closely you'll see it.

You mean the wavy vertical bars that sorta sweep across from left to right?

It's probably the fluorescent lighting interacting with the framerate/shutter speed of the iPhone camera. Some refer to it as a "beat effect."

Yes, that's it, but my lights are turned off.
