They liaise closely about continuity with other departments including costume, makeup and hair, props and lighting. Where pick up shots are required, Script Supervisors provide actors with dialogue start points, and exact continuity details. They also ensure that other departments are aware of the status of each shot, and that clapper boards are marked up accordingly. Where more than one camera is used, they ensure that each camera's output is accurately identified. They confirm directors' take preferences and note these for post production. They often assist sound mixers in taking additional notes of any recorded wild tracks or voice–overs. Script Supervisors retype scripts to reflect any major dialogue changes, and markup scripts with slate numbers, cut points, and other relevant details for post production. They prepare detailed daily continuity reports, editors' daily log sheets and daily production reports. They also provide production with records of the requirements for any outstanding shots or inserts.
