shutter speeds and 24p

Hey All-

I just want to clarify something I've read here.
If I am shooting 24p and have some action, movement, going handheld, etc, will going to a higher shutter speed, 500 for instance, reduce the unwanted blur? Do higher shutter speeds in 24p actually enable the camera to handle motion better?

If so, what shutter speeds tend to work best?
And does it require closing down the iris?

Thanks everybody!
 
Weather you close down the iris or not depends on how its lit. I wouldnt shoot general action at 1/500th. Maybe 1/120th.
 
I shot some dance footage (hip hop, ballet, african, latin) at 1/120th and it looked great. I agree with the NCJE that 120 works for general action. When walking around or shooting slower stuff I'll set the shutter to 1/60th.
 
As per Davids post ......personally I would try to shoot a more static scene at 1/48th with 24p. But I guess its an artistic choice in the end.
 
A faster shutter speed will mean a darker image and you'll have to iris up. But if there's no movement, there's no difference from frame to frame. A high shutter speed can cause a staccato feel to movement because there's a big difference between frames. But if one frame is the same as the next . . .

So, NCJE, are you saying that there would be virtually no differences in shooting at a high or low shutter speed when shooting a slow scene?

Almost unoticable... but there are few scenes where someone at least doesnt cross the room etc and 1/120th is probably a bit off for this. Basically I am aiming IN GENERAL to keep my iris at a point that retains max focus.. so 1/48th would probably give me more room to move on a very STATIC shot.
 
shutterspeeds kind of confuse me. What happens if you use something like 1/24 on 24p for just someone walking across the screen? And, what about like an action sequence. Is it really strobby?

Imagine if you were watching a boat in the ocean. Imagine if you opened your eyes 24 times a minute. Think of how the movement of the boat would look. Each time you opened your eyes, the boat would have moved a lot. That is because you had your eyes closed sometimes while it moved. If you opened your eyes 60 times a minute, Once a second, you would see more of the in between parts of the movement. Your eye would be closed less. It is the same with shutter speeds. If you shot someone walking across the street at 1/24 you will make the camera open its eye 24 time that second instead of the normal 48-60. So you will lose info and make the image appear strobing, as its "eye" was closed during part of the movement.
 
ah, thank you for that reply. So, why does filming at a faster shutterspeed make things choppy? You are getting more information correct? And for like screen capture/slow motion, you want what kind of shutterspeed?

Sorry for the 'newb' questions.
 
The faster the shutter speed, the less time the image is exposed for.

The slower the shutter speed, the longer the shutter is open, and thus the more blur you'll see on moving objects. 1/24 = really blurry, 1/2000 = really crisp. But that doesn't make 1/2000 "ideal", it would look extremely choppy and stroby. Film usually uses around 1/48.
