I will be shooting my brother's wedding this weekend (there is a pro photographer who'll be taking picures so my job is of secondary importance and it's basically to have some footage to turn into a music video). Anyway:), I have a question regarding the shutter speed. I do realize it should ideally be double fps, but I will be shooting at 30p and I know that the lights at the venue flicker at 60fps, so which would be the lesser evil: to increase my shutter to, say, 1/70 or decrease it to 1/50? Or maybe other values? How significantly would it affect the footage? Let's, for the sake of the argument, ignore the fact that I can shoot 24p. I'd appreciate any suggestions.
