If you want / need to shoot 25 shoot 25. Outside of North American TV I can't think of any reason you need to shoot 30.

Don't make your life harder than it needs to be just because

As I understand it, it's because the frame rate which works best for phones, tablets and computer monitors is 30 fps. This is worldwide, not just north America. And the old NTSC vs PAL thing no longer applies as we don't use CRT televisions and monitors and never will ever again. The one problem which remains is shooting indoors using an anti-flicker setting, but because of my limited video experience I don't know how big an issue this actually is.

You are correct.

As I understand it flicker results from an incompatibility of the AC frequency (50Hz) and the shutter speed, not the frame rate. So, normally you would shoot 30 fps at 1/60th. That can produce flicker from 50Hz lights. In those situations, just shoot at 1/50th. My experience shooting in 50Hz places around the world at 30 and 60 fps is that flicker is not always a problem, and when it is I can see it in the viewfinder (LCD) and then I adjust the shutter speed.

Thank you! I'll have no reason to use high shutter speeds for my potential subjects, so I should be fine.
