What does a script supervisor do?

The script supervisor tracks continuity and records what was shot. They maintain the lined script, log every take, note continuity details (wardrobe, props, screen direction, timing), and give the editor and production the notes needed to assemble the film correctly.

What is a lined script?

A lined script is a copy of the screenplay with vertical lines drawn down each scene showing which shots cover which lines of dialogue and action. A solid line means the action is seen on camera; a wavy line means it's off-camera. It tells the editor what coverage exists.

What is a continuity log?

A continuity log records the details that must match across shots — wardrobe, hair, props, screen direction, and action — plus take numbers, circled (preferred) takes, and timing. It prevents jarring mismatches when shots are cut together.

Script Supervising: How to Manage Continuity Log Sheets on Set

What a script supervisor does and how continuity logs work. The essential logs — facing pages, lined script, and continuity notes — that keep your edit from falling apart.

The script supervisor is the memory of the production. While everyone else focuses on the next shot, they track whether the coffee cup was in the left hand or the right, which takes the director liked, and exactly what coverage exists for the edit. Without them, the cutting room becomes a puzzle with missing pieces. Here's what the job involves and the logs that make it work.

What a script supervisor does

They own continuity and records:

Track every detail that must match across shots.
Maintain the lined script.
Log every take — what was shot, which were good.
Hand the editor and production the notes to assemble the film.

They sit beside the director, watching for the mismatches that would otherwise surface too late to fix.

The core logs

1. The lined script

A copy of the screenplay with vertical lines drawn through each scene, one per camera setup, showing which shots cover which lines:

A solid line = that action/dialogue is on camera in that shot.
A wavy line = it's off camera (heard, not seen) in that shot.

At a glance, the editor sees exactly what coverage exists for every moment.

2. The continuity log

Records the matching details and take information per setup:

Wardrobe, hair, makeup states.
Props and their positions.
Screen direction — which way a character faces or moves (crucial for the 180-degree rule).
Take numbers, circled takes (the preferred ones), and timing.

3. Editor's / daily notes

A per-day summary for the editor: takes, comments, timing, and any issues, so the cutting room starts informed.

Why continuity errors are expensive

A missed continuity note becomes a visible jump cut — a glass that refills between shots, a tie that changes knots. Caught on set, it's a quick reset; caught in the edit, it can mean a reshoot. The script supervisor's logs are cheap insurance against costly mistakes.

It starts with the script

Every log traces back to the screenplay — the scenes, the action, the coverage. When the script, breakdown, and shot plan live in one project, the supervisor is working from the same source of truth as everyone else, and script changes are easy to track. That connected approach is what Scriptease is built for: the script the supervisor lines is the same one the production was planned from.
