Why does iPhone 1 1 flash when recording video?

IPhone 1 1 is recording video. If you don't want the flash, you can try turning off Smart HDR from the camera settings.

This is because of the new generation of intelligent HDR enabled by iPhone 1 1 series. When recording video, the intelligent HDR algorithm will adjust the exposure in real time according to the subject and the surrounding environment, so that the dark part will not be too dark to cause the loss of details, and the high part will not be too violent and pale. During the whole shooting process, the brightness of the screen has been changing, which also leads to the adjustment and correction of intelligent HDR.

So when we watch it, we will feel the screen flashing, especially the shadow part. Because it is adjusted in real time, we can see the screen flashing from the screen when shooting.
