The 'Grammar' of Television and Film
Television and film use certain common conventions often referred to as the 'grammar' of these audiovisual media. This list includes some of the most important conventions for conveying meaning through particular camera and editing techniques (as well as some of the specialised vocabulary of film production).
Conventions aren't rules: expert practitioners break them for deliberate effect, which is one of the rare occasions that we become aware of what the convention is.
