What a page of a one-liner looks like
Here is a slice of day 3 from a fictional 18-day feature:
| Sc. | I/E | Set | D/N | Pgs | Cast |
|---|---|---|---|---|---|
| 14 | INT | ROSIE'S DINER | D | 2 3/8 | 1, 2 |
| 15 | INT | ROSIE'S DINER, KITCHEN | D | 6/8 | 2, 5 |
| 19 | EXT | ROSIE'S DINER, PARKING LOT | D | 1 1/8 | 1, 2, 4 |
| END OF DAY 3 | 4 2/8 |
The day total is plain eighths arithmetic: 2 3/8 + 6/8 + 1 1/8. Add the whole pages (2 + 1 = 3), add the eighths (3 + 6 + 1 = 10/8, which is 1 2/8), and you get 4 2/8. Some one-liners include a short synopsis under the set name, and most print the calendar date next to the day number ("DAY 3, WED SEP 23").
How crews actually use it
Department heads keep the one-liner folded in a back pocket. A gaffer scanning it can see that days 3 and 4 are all diner interiors and plan a pre-rig. The costume department can count how many days Maya wears her waitress uniform. Because it is short, it gets reprinted with every revision, and everyone checks the revision date at the top before trusting it.
The one-liner doesn't list props, vehicles, or extras counts. Crew who need that pull the long-form shooting schedule, which is printed from the same stripboard.
Where people slip
The biggest risk is an old version. A key grip working from Tuesday's one-liner while the AD sent a revision Wednesday night will show up with the wrong package. Date every version, and on longer shows give each revision a color the way script pages get revision colors.
Another mistake is leaving off the location. "INT. APARTMENT" can mean three different practical locations on a low-budget show, so add the location name or code.
Connections to other paperwork
The one-liner is what the 2nd AD opens to start each call sheet, and the scene list at the top of the call sheet is often copied straight from it. The one-line schedule template has the standard columns, and there is a longer explainer in what is a one-line schedule.
