Why do apples blink in slow motion?

The "slow-motion" shooting of a mobile phone seems to be a moment of observing life more carefully with a magnifying glass, which can make you discover different beauty. But when Apple mobile phone users responded to slow-motion shooting, the picture kept flashing. What happened?

Why do apples blink in slow motion? Because ordinary lights are constantly flashing according to the change of power frequency, the shooting speed of photos in slow-motion mode is much faster than the changing frequency of light and shade, so the previewed and shot videos will have light and shade changes or stripes, so it is recommended to shoot slow-motion videos in normal outdoor light.

Apple's slow-motion video tutorial is as follows:

1. Open the camera on the mobile phone desktop and enter the shooting interface.

2. Slide to the right and select slow motion in shooting mode.
