Question

If you are shooting video at 30 frames per second using a third-party app to achieve natural motion blur, what shutter speed value should you target as ideal?

Accepted Answer

The ideal shutter speed value to target for achieving natural motion blur when shooting video at 30 frames per second is 1/60th of a second. This recommendation is based on the 180-degree rule, a fundamental principle in video production for cinematic motion. The 180-degree rule states that the shutter speed should be set to approximately double the frame rate. In this context, the frame rate, or frames per second (fps), refers to the number of individual still images captured and displayed sequentially per second to create the illusion of continuous motion. So, for a frame rate of 30 frames per second, the ideal shutter speed is 1/60th of a second. Shutter speed is the duration for which the camera&#x27;s sensor is exposed to light for each individual frame. Setting the shutter speed to 1/60th of a second means that for each frame, the sensor is exposed to light for half the total duration of that frame. This specific exposure time creates natural motion blur. Motion blur is the visual streaking or smearing of moving objects within a single frame of video, which occurs when an object moves significantly during the period the shutter is open. Natural motion blur is a desired effect because it mimics how the human eye perceives movement and how traditional film cameras captured motion, resulting in video that appears smooth and fluid rather than artificially sharp or "stuttery."
