Shutter Speeds... when slow, when fast.

What is the difference in quality between shutter speeds and when would you use slower or faster ones? For what type of look or effect? I know it's obviously tied to light, and blur (to counteract strobing) but I think it must also be tied to image resolution, maybe something else and I would like to get some more info on it.

I'm shooting with a DVX100a and a letus economy. Sorry if this has been covered in another thread, I've been searching for a while and am running out of time.

quailty will remain the same regardless of the shutter speed being used. your camera will still record the image in full resolution. IT is simply a quesiton of motion blur.

With the economy, i would try to keep it at 1/120th or under to avoid seeing the GG. But slow shutter can be used very well if done with a purpose . Watch The Bournce Ultimatum.
 
the same reason you see it at high shutter speeds. The GG vibrates at a certain speed. Eventually, if you reach a high enough shutter speed, the motion of the GG can be seen. The lower you bring it, the more of a blur the vibration becomes. And if you go very slow, the effect is that much more.

But, generally speaking, if you are trying to emulate film, then you shoot at 24f with a shutter speed of 1/48th, or shutter angle of 180*
 
Of coarse, that completely makes sense, Thanks PaPa, very helpful. To follow up I read up on it in Barry Greens DVX book, and he mentions the option of using 1/43 or 1/36 to minimize strobing. I've checked and checked and I can't find that as an option on the DVX. Does Barry mention that as an option for film cameras, which isn't anoption for a DVX user, or is there a way to achieve either of those?
 
i think on the dvx, you have an option called syncoscan, where you can manually dial in any shutter speed you want. I may be wrong though. Check it out and see what happens.

But from what i've seen, strobing is something that effects film just as much as it effects video. I see it all the time, especially on the big screen.
 
I'll be damned, there it is. Thanks a million, I don't know how long it would've taken me to find that... and if I even would have. That'll be really helpful in low light situations too. I have one coming up that's going to be a challenge so I think this will help a lot...
