Video Hello friends.
I've got even one technical question.
Since I'm from the photo area, I have often with shutter speeds of 1 / 1000 or even less work. Only then will freeze a fast motifs.
But why do I need a faster shutter speed for video?
My Cam is taken up in 50p. A shutter speed of 1 / 50 second is so standard. I have less light, I can still 1/25gehe feature but jerk. If I have a lot of light I close my Aperture and is sometimes synonymous nor keep the shutter shortly. But this only to have no over-exposure.
But why do you specifically verwednet high shutter speeds?
I read once that work is in Movie with 24p and 1 / 48 seconds. A 25p camera would be there at 1 / 50 second. I would start with 1 / 25 second, depending on the individual images are blurred, but hardly noticeable when playing. If I were to use high shutter speeds, the content difference of each image so large that I can make with 25p a jerk in the movement.
That's the theory. Thus, for me no advantage. Unless one wants to capture slow motion or single images. Then would 1/500natürlich sharper than 1 / 50.
But on the Picture for video and fast action is sharper?
Who me to clarify?

Antwort von Scallywag:
This is already clear to me that it's about motion blur. But you can see in the video just really "sharper" when filming an action sequence with 1 / 500 instead of 1 / 50 second? And if so, the light is worth effort?
Antwort von Mantas:
if it is important to you, worth the.
s just a different look. you do it so synonymous usually very rare.
Crank2 was shot example with very short shutter speed, you see.

@ Scallywag
Your observation is already quite right.
As long as no one wants to document the wing movements of hummingbirds, make short shutteradjustments no sense at all.
The shorter the shutter duration, the next are separated by the intervals and each next image, this is the case, the more jerky the inevitably term view.
As long as no one wants to make Slapstik and motion studies, shorter shutteradjustments make little sense.
Some cameras cover it, however, deficits in the objective area and leave no stopping down more, because the optics are already in open Aperture is blurred, that the diffraction would be unusable at any dimming the Picture and variable ND solutions are not controlled, or too expensive. Therefore, a modified shutter on some cameras is to deal only with difficulty.
Also change the signal to noise ratio shutteradjustments negative, because the ratio changes in fill factor.
Therefore, as HDR images are synonymous always worse in the signal to noise ratio.
