Film, Movie, TV, and DVD
Definition of Film. Film is usually a transparent layer or film, sometimes paper-based, that surrounds a moving object and which gives that object its image. An obvious example of a film is a painted layer of frosting over the top of an already baked cup of coffee. An obvious example of film is popcorn, which is made by popping hot air into a can full of popcorn, which in turn gets covered by a transparent plastic protective sheet before being allowed to pop.
Definition of Motion Picture. Motion pictures are movies that do not move. The term “motion picture” refers to any kind of moving picture – an actual film, a still-life, a computer-generated image, etc. (the only kinds of motion pictures recognized by the American Film Institute are motion pictures and live-action films). An obvious example of motion picture are motion pictures shot on a sound stage, as those kinds of movies are technically called.
Definition of DVD. DVD is an acronym for “Digital Video”. Digital Video is the industry term for any digital recording media that can be read and saved by a computer. So, basically, DVD means “digital” and a DVD copy is “digital copy”.
