Record of all exposed film stock after shooting—length, exposure, damage, storage conditions. Critical handoff to lab and post to catch issues early.
After the last take of a shooting day or a complete production, every film reel must be documented—its physical condition, its handling, its storage. This is not bureaucracy, but damage prevention. The film inventory systematically records which reels were shot, their condition, and the conditions under which they are stored until development. A damaged film in the lab costs time and money later—if one doesn't know exactly when and where the damage occurred.
In practice, it works like this: The focus puller or a production assistant notes for each reel the length (in meters or feet), the exposure conditions (interior/exterior, type of artificial light, time of day), any visible scratches or wear on the film transport, the storage conditions (room temperature, humidity, whether cooled), and when the reel was placed in the film case. Particularly important: Was the reel loaded and unloaded multiple times? Were there problems with the camera? Does the reel have a crease or a dent? All of this influences how the lab approaches development and how the graders will handle the material later. High-speed shots or special exposure experiments must also be noted—the grader needs this information.
The film inventory is forwarded to the lab or post-facility. It is the first line of quality control. If problems arise later during digitization or development—scratches, brightness jumps, color impurities—the team can trace whether the lab or storage is to blame, or if there was a problem with the camera. With digital workflows involving film scanning, the inventory becomes even more relevant: The technician in the scanning room knows precisely how to handle each reel and what to pay special attention to, thanks to the documentation.
Good inventory management saves reorders, reshoots, and delays in post-production. It is one of the few documentations that nobody really sees in the finished film—but everyone notices when it's missing.
