Though it was a relatively common practice in the past, very few filmmakers use Point of View in their work. Point of View is essentially the positioning of a camera so that it appears as though it is the sight line of a specific character, where this is their “Point of View.” This often only happens briefly in a film where you are not intended to see a character yet or if they are intoxicated.
In other generations, this was an entire device, such as the ability to hide the killer’s identity in the original Friday the 13th. Point of View can fit wherever you feel as though it can be worked with, but you still have to identify this in your screenplay. As with almost any film element, there is a format for Point of View in your film’s screenplay.
