K-pop videos are pretty impressive. In this video, theres a scene in a studio with gravel ground, black background, dance scene with the girls, and they have this shimmering top light and I can't figure out how they did this. It's almost like they shined the light through water? or maybe bouncing the light from water to give the shimmer. But how do you do that above the dancers? Maybe there's multiple lights above them moving fast? or maybe the lights are on some DMX system for the effect? Sometimes the camera goes out really wide, so the lights have to be pretty high (unless they were painted out). Anybody know how they did this? It's pretty awesome.

I couldn't find a behind the scenes.
