OK I'm back with another "how did they do this" question. I'm looking at the quick & bright light flash effects you can see at 00:10 and 00:16. Most of the time when I try to do a flash effect with something like a strobe light, you get that "half the screen lit" effect because of the rolling shutter in the camera. Global shutter cameras I assume don't have this issue, but I only have access to rolling shutter cameras like the RED. So when using a RED, how can I mimic this strobe/flash where the entire scene is lit during the flash and not getting that rolling shutter problem? Previously I had tested with some cheap strobe lights and assume the light flash was just too quick for the shutter to grasp. But what if I used photography strobes? Something like the Alien Bee 800s for video? Would I still get the same problem? Maybe there's a more expensive strobe that allows you to change the duration of the flash for the camera to pick it up corectlly? Any model suggestions? How did they do this?

thanks alot guys! This helped alot. I'm going to start looking for places to rent something like this. Awesome feedback on this forum! I feel like I will be visiting here much more frequently!

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.
