Budgetary or scheduling margin built in—for crew overages, equipment failures, or pickups. Standard: 10–20% in indie productions.
Every production calculates a buffer — and anyone who doesn't learn it by the third day on set at the latest. The contingency buffer is not pessimism, but realism. It covers what lies between ideal planning and actual shooting time: an actor falls ill, the location is suddenly no longer available, a scene needs three instead of two shooting days, the material is faulty, a VFX shot needs post-production work.
In practice, a reserve of 10–20% of the total budget proves itself — for documentary projects or guerrilla productions, even 15–25%. The size depends on the production type: feature films with a stable crew can plan more tightly, low-budget productions need breathing room. In terms of time, it works analogously — those planning for 30 shooting days reserve 3–6 days as a buffer. This reserve affects not only the budget but also the shooting schedule itself: intelligent scheduling means not placing critical scenes at the end.
The crucial mistake: production managers who deplete the buffer during shooting and then have no fallback option. A clear set of rules is better — who can access the buffer, when, and who must approve it. Some productions split it: a technical reserve (material, repairs) and a time reserve (schedule slip). Streaming productions often plan more aggressively because post-production is tightly scheduled and cannot simply be pushed back.
The psychological component is underestimated: teams who know that a buffer exists work more relaxed — and often more efficiently. Those who plan day-to-day on the edge, on the other hand, burn out and make more expensive mistakes. On set, it quickly becomes apparent: the best reserve is the one you don't need at all because the planning is accurate. But it must be there.
