Problem phenomenon:
Flickering occurs when shooting slo-mo in indoor lighting environment.
Solution:
When the lighting is turned on indoors or shooting lights at night, flickering occurs when slo-mo photography is used. This is because the frequency of the lighting lamp is 50Hz or 60Hz, which is 50 or 60 times per second, while the slow-motion video is 120fps or 240fps. The human eyes can't perceive it, but it is very slow for high-speed cameras. Therefore, flickering in this case is normal and not a malfunction of the device.
This problem exists in all phones that support slo-mo, and the higher the frame rate of slo-mo shooting, the more serious the flickering screen problem. This is a physical phenomenon and cannot be eliminated.
It is recommended that you shoot slow-motion videos in an outdoor sunny place.
