In pre-production, every step of actually creating the film is carefully designed and planned. The production company is created and a production office established. The film is pre-visualized by the director and maybe storyboarded with the help of illustrators and concept artists. A production budget is drawn up to plan expenditures for the film. For major productions, insurance is procured to protect against accidents.
A storyboard is a visualizing method that creates a blueprint of what the shot sequence should be. The visual images are drawn or made by programs such as Photoshop. There may also be a written caption as needed for each shot. The director is primarily responsible for the storytelling, creative decisions and acting of the film. The unit production manager manages the production budget and production schedule. They also report, on behalf of the production office, to the studio executives or financiers of the film.
In production, video production/film is created and shot. More crew will be recruited at this stage, such as the property master, script supervisor, assistant directors, stills photographer, picture editor, and sound editors. These are just the most common roles in filmmaking; the production office will be free to create any unique blend of roles to suit the various responsibilities possible during the production of a film.
Here the video/film is assembled by the video/film editor. The shot film material is edited. The production sound (dialogue) is also edited; music tracks and songs are composed and recorded if a film is sought to have a score; sound effects are designed and recorded. Any computer-graphic visual effects are digitally added. Finally, all sound elements are mixed into “stems”, which are then married to picture, and the film is fully completed (“locked”).
