Why is the interval of time-lapse photography 5s?

Osmo Pocket supports two delay modes: static delay and trajectory delay.

Slide the touch screen line to the left to enter the shooting mode setting interface, and slide up and down to select the corresponding shooting mode. After entering time-lapse photography, swipe left again to select static delay and trajectory delay. For example, under normal circumstances, the interval is five hours. If the exposure time is also five hours, it must be overexposed, regardless of special circumstances such as filters.
