What is a good shutter speed and F number for movie using DSLR?

[Morne]

Hi all

I'm shooting a short personal movie with guys fighting. If my frame rate is 24 and doing it 720p, what is a good shutter speed for this kind of action? It will be outdoors, midday.

I'll have to set it to manual focus and use a tripod. I was thinking of shutter 1/200 or maybe 1/250 with F between 10 and 15. ISO Auto. What you guys think?
I'm new to shooting with DSLR (with my old handycam I never had to worry about these settings)

1/50 for 24p or 25p. For 30p set shutter speed to 1/60. 50p or 60p, 1/00 and 1/120.

I had the shutter low on 1/50 and also tried 1/60 but it looked a bit too motion blurred. Moving objects is hard to follow as they not clear, a bit over motion blurred if I can put it like that. Is it maybe another setting I'm suppose to tweak?

1/50 or even 1/60 is definitely too slow for live action shots, especially if it's fast live action such as fighting... 1/250 might be enough, but you may have to go even faster to get perfectly crisp frames. how fast I guess it depends on a combination of things, even though I would expose keeping in mind that shutter speed, in this case, is the priority. but you may need to tweak it a bit to take into account the lighting conditions and how much you can compensate with your lens aperture in order to avoid too wide depth of filed (which I guess you may want to avoid to help you get things in focus), and stuff like that..
at the end of the day it's a good thing you shoot digital, there's no better way to find out than doing some test that you can easily check out.
anyway, as for the second question, no, there's no other thing to take into account than shutter speed if you want to reduce motion blur.

Be careful with artificial light, it flickers at the rate of your countries power line. In europe it's 50hz, in america it's 60hz.
That means if you got a shutterspeed other than 1/50 or 1/60, or double as fast, like 1/100, 1/120, it will make lights flicker.

how to overcome this when you need a faster shutter?
