Turnaround math, in plain language

Turnaround is one of those numbers everyone nods along to until it costs them. So here it is in plain language: turnaround is the rest a cast or crew member gets between wrap one day and call the next. Wrap-to-call. That's the whole definition.

The trouble isn't the idea. It's that you're counting it the night before, across a dozen call times, while the schedule is still moving. That's where it slips — and a slip is a forced call, which is real money you didn't budget for.

How to count it

Take the time a person wraps. Add the required rest. If your next call is earlier than that, you have a forced call — you're paying a penalty to bring them back early. The required rest depends on the agreement, but the math underneath never changes.

• Cast on SAG-AFTRA: typically 12 hours, less on some contracts.
• Crew on IATSE: commonly 10 hours, with weekend and distant-location variations.
• Non-union: whatever the deal memo says — so the number actually has to be written down.

None of that is exotic. It's subtraction. The reason it goes wrong is that turnaround is per person, and a real day has a dozen different wrap and call times stacked on top of each other.

Why NIGHT-to-DAY is the one that bites

Most turnaround is fine because the day shifts forward gently. The one that catches people is the swing from a NIGHT scene to a DAY scene. You wrap at 4am. The next day is exteriors with a hard light call. Suddenly the rest you owe runs straight through the morning you wanted to shoot.

If a NIGHT day is followed by an early DAY day, check turnaround before you check anything else. That's where the forced call hides.

This is exactly the kind of thing that's invisible on a spreadsheet and obvious on a board. When the two days sit next to each other, the gap between wrap and call is right there — and so is the fix, which is usually moving a scene or flipping the order of two days.

Catch it in prep, not on the cost report

The point of doing this in prep is that the fix is still a drag. On shoot day the same problem is an overage report and an awkward conversation. In prep it's moving a strip and watching the gap go green.

AD PrePro flags turnaround as you build the schedule — per person, across SAG-AFTRA, IATSE, and non-union profiles — and tells you which day caused it. It won't make the call for you. It just makes sure the NIGHT-to-DAY swing isn't the thing you find out about at 5am.

Count it as wrap-to-call, watch the night-to-day turns, and fix it while it's still a strip. That's the whole game.
