barry,

i've searched for shutter speed topics and have found a great deal of info, but yet am not sure if my question is being answered, so i thought i'd ask directly

i'm shooting car tracking shots for a doc and though i know the foreground will be very blurred, what is the best shutter speed to use to minumize background blur, but yet retain the best 24p look?

i've been shooting at 1/24....i don't know if that is the camera's default out of the box or if i accidently changed it somehow somewhere, but that's what i've been shooting most of my stuff in. it looks great for interviews and steady shots, but pans, (slow pans) and the car traking shots are still very blurry.

shutter speed is one of the few things i've haven't spent a great deal of time learning about and i feel it's time.

so what's the best shutter speed for car tracking shots in 24p?

what's the best "general" shutter speed for use in 24p?

thanks

carl
 
1/24 will be very blurry indeed.

The general shutter speed on a DVX100 is "shutter off", which is 1/50th. You can also go into the synchro-scan menu and choose 1/48.0. Those will give the typical filmlike motion blur. If you need more exposure and more blur you can use synchro-scan to get a slower shutter speed, like 1/43.0, but don't go down below 1/36.0 or so or the blur may start to overwhelm the shot. In general, movie cameras stick between 1/43 and 1/60, so you should too if you're trying to make film-looking footage.
 
Barry, what about shooting under fluorescent lights? I know that CINE-LIKE Fluorescent will compensate for the green colors, but I'm not worried about that. I've heard about fluorescent lights having refresh rates, and I feel that I need to shoot around 1/43 to aviod major strobing in shots involving a lot of camera movement (Like a quick pan, or the "handheld" effect - sorry, i didn't know what else to call it.) I'm working on a short right now. Am I worrying too much? Where's my paper bag? I need coffee.

Nevermind, I just found the answer to my question in another thread. I'll just experiment with the shutter speeds and go from there. I think I can figure out ways to carry out certain shots with the shutter at 1/50 or 1/60. It's a learning process. :)
