Building one around sunset
Take a practical farmhouse location booked for one day with two scenes:
- Sc. 30, EXT. FARMHOUSE PORCH - DAY, 1 4/8 pages
- Sc. 31, EXT. FARMHOUSE PORCH - NIGHT, 2 pages
Suppose sunset that day is 7:05P (check yours in the sunrise sunset planner). The AD wants the day scene finished with good light before the sun gets too low, and the night scene started once it is fully dark, around 7:45P. Working backward: shoot scene 30 from 2:00P to 5:30P, lunch at 6:00P while the sky dies and electric pre-rigs the night look, and start scene 31 at 7:45P. With a 12:00P crew call, a 12-hour day wraps around 12:30A including a 30-minute meal.
On the call sheet:
Day 7. General crew call 12:00P. Shooting call 1:30P. Sunset 7:05P. Lunch 6:00P (walkaway). Est. wrap 12:30A.
Using splits to change over
A crew coming off a week of day work can't jump to a 6:00P call Monday if they wrapped Friday late, though the weekend usually handles that. The bigger use is mid-week. If Wednesday's call is 7:00A and Thursday and Friday are nights, a Thursday split with a noon call steps everyone five hours later, and wrap at 12:30A leaves room for a Friday evening call. The turnaround calculator will show whether each step is legal for cast and crew.
Going the other way (nights back to days) is harder, because a split still wraps after midnight. That's why weekends usually carry the reverse flip.
Things that trip people up
The first meal on a noon call falls at dinner time, and the second meal lands late at night, so catering has to be booked for two services at odd hours. Check meal timing against your union agreements with the meal penalty calculator.
A split day also puts pressure on the day work. If scene 30 runs long, the company loses the magic-hour window and ends up shooting part of the day scene after sunset, which doesn't match. The AD should have a clear cutoff for the day scene and a plan (often a pickup shot later) for what's left. If the day scene keeps slipping, day for night for a few pieces can save it.
