Scan — Imax Film

An uncompressed scan of a single 15-perforation frame at its full potential can result in files as large as 1.5GB per frame . Because of these immense data requirements, scanners like the custom Lunr scanner may digitize at 16K before down-converting to a more "manageable" 8K (roughly 200MB per frame) to allow for over-sampling and superior detail retention.

As of 2026, research labs are experimenting with using electron beam techniques. However, storage is the bottleneck. A 90-minute feature scanned at 16K/48fps (as Avatar 3 was partially shot) would require nearly 2 Petabytes of RAID storage. imax film scan

Traditionally, IMAX films were telecined or scanned using older, analog technologies to create video masters for distribution. These early scanning methods, while groundbreaking at the time, had limitations in terms of resolution and color accuracy. As digital technology advanced, so did the methods for scanning film. Today, IMAX film scanning leverages state-of-the-art digital tools to unlock the full potential of IMAX footage. However, storage is the bottleneck

In the high-stakes world of modern cinema, the "IMAX film scan" is the bridge between the visceral texture of analog film and the digital precision of today’s theaters. The Story of the Scan
