proper shutter speed for HDSLR video?

AliZaman · 17th of September 2010 (Fri)

hey everyone, please mind the amateur question, but hopefully someone will be able to help me out.

im a little confused as to how the shutter speed effects the video.
i have read on various sites that shutter speed should always be double the FPS of the camera, so for 24fps, shutter should be 1/50(rounding up).

now my question- am i able to play around with this number? as in, can i just adjust the shutter speed as i see fit to get the exposure properly? or will that have some other effects on the video?

Thanks!

Longer shutter speed will have more motion blur and shorter will have less (more home videoish). It's all about what you want to shoot, but the "official rule" is double the framerate.

you can change it a little, but generally you want to shoot at double the framerate. It comes from the old film cameras where the shutter had degrees and so you shot at 180 degrees. It transfers to double the framerate.
(I think that is right, but I could be wrong)

Another thing though, you can certainly use higher shutter speeds, mostly for effect. Think of Saving Private Ryan. The movie was shot at a high shutter speed so that the action seemed "jumpy" it is just a look. If you are going for that, crank your shutter speed.

I hoped that helped a bit.

Heres a little animation that explains why its 180 degree. If a different shutter is needed the the spinning disc would be different size - say 90deg. In video/dslr shutter blades are fixed but open and close according to speed set. So according to frame rate you would use double for shutter to equal 180deg. 24/25p = 50fps (not exact for 24fps) and 30fps would require 60fps. This factor was one of the reasons people in PAL europe kicked off about 500D frame rates as in europe lights/electric are 50hz not 60hz in USA so having to use a fixed 60fps as limited to 30p would cause flicker under certain lights conditions.
