How do I record video without mirroring?
Go into the camera settings and check the toggle for INVERT PHOTO.
Why is my video flipping?
There is a reason for that — the camera on your device is not a like a mirror but rather like a person looking at you. From the perspective of a person facing you, your left is their right and vice versa. So, when a camera records, the video turns out flipped i.e. left becomes right and vice versa.
