60p vs 30p and Shutter Speed for Action Sports

I've volunteered to video a speed skating and figure skating event next week using my Canon XF300, which I recently obtained. I am wonder if for such action sports it is better to shoot in 30p or 60p, and what is the best shutter speed. I will be shooting at 1280 x 720

I've seen advice on the web that runs the gamut, with 60p at 1/125 currently in first place.

I would like to get the sharpest yet smoothest motion I can get. Any advice?

Thanks.

It depends. Do you want to get slowmotion? Then shoot at 60p, because you need to convert it to 30p and get 2x slowmotion, spprts people love slowmotion. If you shoot at that frame rate, set your shutter to 1/125s or higher (the higher the better for slowmotion actually, if there's plent of light go to 1/250s or 1/500s, it makes slowmotion crisp and clear)

If you don't want slowmotion, and deliver in normal speed, shoot at 30p. At that frame rate, I'd shoot at 1/125s too to get clear motion, or 1/60s if you want filmic slightly blurry motion.
 
Thank you. At this point I am not after slow motion. I thought I read somewhere on the web that for fast moving subjects it is best to shoot at 60p and then change it in Premiere into a 30p timeline. If that is feasible - I don't know - then, perhaps, I might have the best of both worlds, shoot 60p, use a 30p timeline and still have the option of smooth slow motion if I want. Does that sound reasonable?

Thanks, again.
 
If you shoot at 60p, drop to 30p timeline and render to 30p, you get 2x slowmotion.


If you want, you can shoot at 60p, and deliver the project at 60p at normal spe ed, and still have the option to slowdown to 30p. 60p shown at normal speed doesn't look bad for sports, it works.

Unless you mean you take the 60p and pulldown to 30p by deleting 30 frames, and it will play at normal speed at 30p. Not a good practise I tried! :D and far different from shooting at 30p from the start.

-Shoot 60p & deliver in 30p for slomo and deliver at 60p for normal speed scenes
-Shoot 60p & deliver in 30p for slomo, and pulldown to 30p and deliver at 30p normal speed (not recommended by me)
-Shoot the moments you want to be slowmotion at 60p, and the normal ones at 30p, (ideal option)

Shoot at a highest shutter speed for the slo-mo scenes, and at 1/60s at 30p for normal speed, this gets the most filmic/smooth motion, if it's not required to have that smooth motion, shoot at higher.
 
I hope someone gives us insight on 60p pulldown to normal speed 30p by discarding half the frames. While from my trials it is a bad practise but I would like to know exactly how it differs from shooting at 30p and what are the technical downsides of doing this, because it would be a pretty good way to shoot if you're unsure whether to go Slow motion or not.
