Quote: I often read that slow shutter speeds are necessary when shooting video - something like 1/50 second if rendering at 30 fps, or 1/100 to 1/150 if rendering at 60 fps. I've shot a few video clips at 1/320 to 1/500 and I don't think I see any ill effects. What am I missing? What should I be seeing if I've shot at too high a shutter speed?

Thanks - Bill Hansen

The main effect of higher shutter speed is to reduce blur and you do need bright light.

I doubt you can have too high shutter speed, only if the light level is too low.

Exposure is a combination of shutter speed and aperture. Since video is limited to 60 Frames per second for NTSC or 50 frames per second for PAL, there is a limited range of shutter speed and aperture that makes for correct exposure.

The number of frames per second have little to do with exposure. Exposure is the amount of light to produce a image.

Thanks Carl - That's very welcome reinforcement of my own experience. I asked the question about shutter speeds because a member of one of my photo groups (Cayuga Nature Photographers) insists that shutter speeds must be slow, well below 1/200. There are also multiple postings to some of the DPReview forums which claim that shutter speeds faster than ~ 1/150 will result in "harsh" or jerky video.

There are times when the light is bright, and even at ISO 100, the shutter speed would be 1/500, or more. If the shutter speed *had* to be 1/150 or slower, I'd need a ND filter, which could be a nuisance. Those faster speeds have seemed to work for me, when the light is adequate.

I would rely on the camera's auto exposure to determine the shutter speed.

Today's digital cameras are darn good at what they do.

The real answer can be determined by experimentation. A series of tests would tell you how your camera handles different situations.

I think what causes "harsh" or Jerky video is handholding the camera. If the camera is on a steady support, you do not have shake or jerky video. Over stabilization can cause a less than pleasing video.

I almost never use auto exposure. My very strong preference is some form of control, keeping the ISO as low as possible, thinking about whether I want a deep depth of field or a shallow one, whether I'm photographing (or shooting video of) a sports event, wildlife, a social occasion, etc. Each subject has its own demands. Right now I'm practicing with a reasonably long focal length lens, 100-400mm, because I'll be doing wildlife on my next trip. I'll be using the 400mm focal length most of the time on this trip. It's been years since I've had the chance to shoot wildlife, and it's been both a humbling experience and an entertaining one, to re-learn some of the skills I had "back then".

Hi Bill

The rule of thumb is to shoot at twice the frame rate.

I'm in PAL land so I so my shutter speed is 50 as my frame rate is 25 or multiples of those numbers for everyday stuff.

I use 250th sec for fast action - motorbike racing etc as I find the slow motion is much much better and I get pretty good results.

Here's a tutorial from Phillip Bloom:
