Film and video production businesses plan and create moving-image content for organisations, broadcasters, agencies and private clients. Work may include corporate films, promotional videos, adverts, training materials, documentaries, event recordings, online content and independent film projects. Some specialise in a particular format or subject, while others handle projects from initial brief through to delivery. Typical services include developing concepts and scripts, preparing budgets and schedules, arranging locations, cast and crew, and filming with cameras, lighting and sound equipment. Post-production can involve editing, sound mixing, colour grading, graphics, animation, subtitles and preparing versions for different platforms or broadcast specifications. Clients may commission a complete production or individual stages, such as filming, editing or animation, depending on the project and the skills available.
