Film production businesses develop and make moving-image projects, including feature films, short films, documentaries, animations and other screen content. Their work may begin with developing an idea or script, researching a subject, arranging funding and planning the production. Depending on the project, they can organise casting, locations, schedules, sets, costumes, equipment and the crew needed to film. Production services can cover filming with cameras, lighting and sound equipment, as well as coordination of actors, presenters and contributors. After filming, businesses may edit footage, add graphics or visual effects, correct colour, create music and sound effects, and mix dialogue and sound. They can prepare finished films in formats suitable for cinema, television, online platforms or festivals. Some businesses handle a project from initial development through delivery, while others specialise in particular stages or types of production.
