They are generally responsible for decisions about the editorial content and creative style of a program, and ensuring the producer's vision is delivered.
Their duties may include selecting cast members, conduct rehearsals, work with set designers, location scouts and art directors, originating program ideas, finding contributors, writing scripts, planning 'shoots', ensuring safety, leading the crew on location, directing contributors and presenters, and working with editors and music supervisors to assemble and make sure the final product meets the producer and director's vision.
Live television shows require a style in which a constant stream of instructions is given by the director as the show progresses, calling for various pre-recorded shots to be played, cueing presenters, communicating with camera and sound operators, and supervising the placement of professional video cameras (camera blocking), lighting equipment, microphones, props, graphics and the overall pacing and feel of the production.
Other than quickly calling out commands, the television director liaises with the floor manager.
