Video shutter speed affects how much motion blur appears in each individual frame. A common starting point is the so-called 180-degree shutter rule, which means using a shutter speed roughly twice the frame rate.
Common starting points
- 24 fps: about 1/48 second, often rounded to 1/50 on cameras that do not offer 1/48.
- 25 fps: about 1/50 second.
- 30 fps: about 1/60 second.
- 60 fps: about 1/120 second or the nearest available setting.
- 120 fps: about 1/240 second or the nearest available setting.
Why use this relationship?
It usually creates an amount of motion blur that viewers perceive as natural. Very fast shutter speeds make each frame look crisp, which can make motion feel staccato or harsh. Very slow shutter speeds create heavier blur.
Is the 180-degree rule mandatory?
No. Sports, action, visual effects, low-light shooting, or creative choices may justify a different shutter speed. It is a starting point, not a law.
Why does video need neutral-density filters?
In bright light, you may want to keep a relatively slow video shutter speed and a wide aperture at the same time. An ND filter cuts light without forcing you to change those creative settings.
