I want to simulate a red carpet scene for a music video where the aritst gets out of the car and is bombarded by multiple photographers when getting to the red carpet. They are flashing and taking photos all in his face. I want to see the flashes but without the rolling shutter effect (example attached) while shooting on RED dragon. Does anyone know of alternative ways to achieve this? Is there a special type of light/strobe that is long enough not to see this effect? My first thought was to shoot this scene on a camera with global shutter, but Id rather keep it all on my RED dragon and not have to color match later.
Is there a particular combination of frame rate and shutter speed I can set to fix this?
