Make a movie. What are the components?

The film production process is basically divided into five stages: 1, and the development stage: writing a script and transforming it into a blueprint for shooting. 2. Pre-production: To prepare for the actual shooting, actors and working teams will be hired, shooting locations will be selected, and scenes will be built. 3. Shoot the original footage of the recorded movie content. Post-production: editing the film and editing the dialogue in the play at the same time (but separate from the film); Create, play and record background music (and songs), design and record sound effects; Make and add computer "visual" digital functions. All audio elements are mixed into a master track named "stem", and then the master track and the movie are merged. At this point, the film was officially completed (Hollywood called it "locking"). 5. Sales and distribution: hold a preview film for potential buyers (distributors), and the distributors will send the film to cinemas and/or distribute it to home digital media such as DVD. The Hollywood-style production process usually takes three years. 1 year is the development stage, with pre-production and formal shooting in the second year and post-production and distribution in the third year. The nature of the film determines the scale and type of work team needed in the production process. Many Hollywood adventure movies need computer-generated images (CGI), which must be produced by many 3D model designers, animators, dynamic painters and others. An independent film with a low budget may only be produced by a small team, and usually the salary is very low. Every place in the world uses different techniques, performances and styles to make movies, and it also has a completely different budget range, from documentaries sponsored by county and city governments in Chinese mainland to American studio movies, which are completely oriented to commercial profits.
