Conventions governing the techniques of film and how they are used to tell a story. Film techniques include cinematography, mise-en-scène, and editing (see close-up; continuity editing; long-shot; mid-shot) and the way in which these conventions are used by practitioners of the medium to signify certain meanings (see cutaway; establishing shot; point-of-view shot; shot/reverse-shot). ‘Grammatical rules’ can also be broken: for example, through jump cuts or by crossing the line. Semioticians have disputed its comparability to grammar in the strict linguistic sense.
