What does POV mean?

POV stands for point of view, and is used to indicate that the audience is seeing something from a specific angle or through a particular character’s eyes.

POV shots can also sometimes be indicated without using POV, as John August demonstrates in this example from johnaugust.com:

Evan is three spoonfuls into his muesli when he hears an EXPLOSION outside. Racing to the window...

EXT. KITCHEN WINDOW / FRONT YARD – DAY

...Evan leans out to see his Toyota Yaris flipped over on the front lawn, engulfed in flames.
