Note that the entire frame rate selection is different between the two standards, PAL tending to be 25 (and multiples) and NTSC being just under 30 (29.97) (and multiples). This continues into 100 and 120-minus on the R5.yeah PAL doesn't do 24fps
FWIW, you can use both 24 and 30fps with 50Hz lights, just make sure your shutter is set to a multiple of 1/50s. That isn't a proper 180° shutter angle, but it's good enough for filming my kidsOk so I see (Google) thats because of the lights.
Well thanks a lot for the help
