What does P.O.V mean in the script?

Page (short for page) O.V is the initials of point of point, which means point of view.

Usually POV shot is also called subjective camera, which is a subjective lens.

A shot representing the character's point of view in the film. When the character scans or walks in the scene, the camera represents the eyes of the character and displays what the character sees.

For example, in the movie Kick-ass, Super Girl kills the villain in the dark and saves Dad and Kick-ass from the main perspective.

But the subjective lens is not necessarily the first perspective in the strict sense, and it can also be shot from the shoulders of the characters. At the same time, the use of lens is only a part of film production. Only by combining the plot, stage props, actors' performances and editing can an excellent film be completed.
