A copy of the shooting script which is prepared by the script supervisor during production to indicate, via notations and vertical lines drawn directly onto the script pages, exactly what coverage has been shot. A given vertical line indicates, via the line's start and end point, what script material is covered in a particular shot, and whether given dialogue or action is on-screen or off-screen in the shot, indicated by the line changing between straight and wavy respectively. Different coloured lines usually represent certain types of shots: close-up, insert, steadicam, etc. Each vertical line is also notated with the slate of the shot (e.g. "3C"), the printed takes (e.g. "1, 3, and 4"), and a brief shot description (e.g. "M2S Rolf & Liza"). The lined script also frequently incorporates the script supervisor's script notes on the facing pages for a given scene. The lined script is used by the film editor as a reference to what coverage was shot and to changes made to the script during production. Lined scripts give editors a quick view of all available coverage at a glance, so that he or she can make quick editing decisions without having to sort through all the footage repeatedly.
