Hi,

i have general questions about shutter speed.

1) Which value should I choose to film normal scenes?

2) Which shutter speed should i choose on scenes that the object (people or car) moves fast

3) Depends the shutter speed value on the contry (PAL or NTSF) ?

4) It's normaly to work with differents shutter spped values on the same film or music clip or have i to use allway the same spped on the hold project?

5) Have I to choose diferent shutterspeed if I work in 24p or 25p etc.?
 
I'm no expert, but I know that generally you want your shutter speed to be twice your frame rate.

So at 24 frames per second, shoot 1/48
At 60 fps, shoot at 1/120

The 'traditional' value for the 'shutter speed' at 24 fps, has been 180 deg, or 1/48th sec, but there is a large variation from that.

The 180 degree business has to do with how the shutter was implemented on film cameras, and has been 'grandfathered' into modern digital terminology, so one does not have to invent a new language, or set of terms.

As such, there is little 'effective' difference between 1/48th and 1/50th, the latter being the most likely setting one will find on various digital cameras, especially the video DSLRs.

The setting gives a certain 'motion' blur, which lessens the apparent 'choppiness' of motion on film, or a 'strobing' effect. (more apparent if one looks at say the spokes of wheels turning, or the like...)

For higher frame rates beyond 60 fps, it seems that the recommendation is to have the frame rate and shutter speed set equally, rather than at the 180 deg, or 1/120th sec. shutter speed. Unless with the increased framerate the goal is 'slo mo', then 180 deg. (or one half the framerate duration.) seems to be recommended.

If you maintain the 1/60 shutter speed for 60 fps, then you don't 'lose' a stop of light for the exposure. If you set the shutter speed for 1/120, you have lost a bit more than a stop, relative to the 24 fps, 1/48th sec., and so must have your scene lit brighter by a stop to compensate.

1. 180d or 1/48th
2. If you want less blur change your shutter to maybe 1/500th or just leave it at 180d
3. Don't know
4. I use different shutter speeds so that I can do things like "freeze Frame"
5. No you don't. If your filming a "movie" you want 180d. If your filming your kids soccer game you want 1/1000
