Action Film Look

[spunkme99]

I've been wondering about this for a while, don't know if it's a "special effect" , but I've noticed like in 28 days later, I think saving private ryan, and others, that on certain action sequences in the movie the film seems to have a 'fast/crisp' look to it (sorry, I can't really describe it)

It's also in Matrix Reloaded when Neo fights those guys near the staircase and one of the guys takes out a vase directly in front of the camera.

Are they just messing with the film speed or shutter or what?

Don't know if it's a special effect, or maybe I'm just imagining it

Shutter speed is how you get crisp images.
Think of shutter speed as motion blur control.
That's it!
If you lock your camera to a tripod, hit record with the shutter speed set to 1/60th of a second (standard for video) then run past the lens right in front of it you will be nothing but a blur.
Now set the shutter speed to 1/2000 of a sec. and run past. Take a frame from that and you will be cristal clear.
Now on a camera with a manual iris control like the DVX the shutter speed can be useful to shorten your depth of field by increasing the shutter speed. Why? because a higher shutter speed like the 1/2000 I mentioned requires more light forcing you to open the iris which decreases the depth of field. So shutter speed has a few uses but the main thing to think of when you change shutter speed is motion blur. I can't stand a high speed shutter on most things because it's really irritating to watch quick things in frame all the time, cristal clear. Although I'ts very useful when you HAVE A REASON to use it.

In Saving Private Ryan it's that fast shutter speed. I think like 1/120th or 1/250th. Too fast and you'll end up giving me a seizure from all the strobing.

Awesome, thanks for the quick replys! I thought it might had been the shutter! That's been bugging me since I first saw it in 28 Days Later (or was it Blade...)

Now I'm gonna abuse the hell out of it!

Just playin

on a film camera it's adjusting the "shutter angle" on a video camera it's adjusting the "shutter speed"...and i read somewhere that to mimic saving private ryan the rate for a vid camera would be about 1/250.
