well if skiing is too fast-paced for 24p, then it also is for 30p.
i don't like 30p because it just is a weird frame rate. 60p is good for slow motion, and 24p is good for lifestyle and achieving the 'film look.' so 30p just doesn't seem useful to me. can't do slow motion very well with it, and it doesn't have as nice a feel as 24p does.
most people who film skiing shoot at 60p, but i know there are kids on here who believe in shooting at 24p to maintain the film aesthetic
