My understanding of Cinematic Language
Cinematic language is the use of techniques the filmmakers use to convey meaning or mood to the audience. This may include lighting, mise-en-scene, cinematography, performance, editing, and sound. For example, if a movie starts out with many quick cuts, and fast camera movements, it may be suggesting to the audience that the movie is very fast paced. The same thing if a movie takes place in a dark scene, it may signify to the audience that the movie is possibly a thriller or a sci-fi genre type film.
