How does the shutter speed affect video quality and motion in videography?

Shutter speed in videography affects video quality and motion by controlling the amount of motion blur in the footage. A faster shutter speed reduces motion blur, resulting in a sharper image and smoother motion. On the other hand, a slower shutter speed can create a more cinematic or natural look with more motion blur. Adjusting the shutter speed can help achieve the desired visual effect in a video.
