Why is the smoothness of previewing video affected after the POCO X7 Pro reduces the frame rate in dark environment?

The POCO X7 Pro uses a 50 million-pixel rear camera. In a dark environment, the brightness will be insufficient due to the amount of light entering. To achieve a better picture quality, we have done appropriate frame reduction processing for 60 frames to achieve better picture quality.
If there is a freeze during recording, you can move the phone to an environment with sufficient light to record or turn off the automatic frame rate in the settings to ensure the smoothness of the picture.
This phenomenon will not have a negative impact on the camera and the phone, so you can use it with confidence.
