Cinematic language is a reference to the combination of elements that make up the mode of communication between a film and its audience. It is the combination of methods, techniques, and conventions that use moving images to tell a story -- mostly without the help of spoken words.
A cinematic language is typically associated with a film's director and combines elements such as camera shots, angles, and movements, lenses and focus, mise-en-scène, lighting, sound, music, editing, and performance.
