In video, the shutter speed you use will almost always be which of the following?

• A. one second
• B. several seconds
• C. a frame duration in seconds
• D. a fraction of a second

Answer: (D)

In video, the exposure time per frame is a fraction of a second. The frame rate sets how long each frame is meant to exist, but the shutter speed—the actual time the sensor is exposed for each frame—is typically about half of that frame duration. This keeps motion looking natural with enough blur to feel smooth, following the 180-degree shutter rule. So, for common frame rates, you’d use roughly 1/48 second at 24 fps or about 1/60 second at 30 fps. That’s why the shutter speed is almost always a fraction of a second rather than a full second or several seconds.
