I was shooting an rave event last night with many flashing lights and strobes. I shot in 1080 24p, shutter speed of 1/50. I noticed a lot of banding. In reading, I just want to clarify that if I move my shutter speed down to 1/40 or 1/30 in these types events, this will take care of the vertical banding issue? Will I still get it when I say go up to 1/80 shutter speed?
