However, the long-term survival of the practice rests on the hardware. As noted by panelists at the 8K Association, there are "few suppliers of appropriate equipment" for IMAX scanning. As long as filmmakers like Christopher Nolan demand to shoot on 70mm IMAX, and as long as film archives need to preserve history, the esoteric art of the IMAX film scan will continue to exist—bridging the analog past with the digital future, one 35-second frame at a time.

Because of this physical scale, the analog resolution is staggering. While 35mm film can resolve around 6,000 lines (6K) of horizontal detail, an IMAX negative captures an estimated equivalent of of horizontal resolution. In terms of still photography, an IMAX frame holds the equivalent of 70 to 130 megapixels of data per frame. This massive "information density" is why scanning IMAX film is not just a matter of slapping a strip on a flatbed; it requires specialized engineering to extract that detail without losing it to compression or noise. However, the long-term survival of the practice rests
: Once scanned into raw data, the footage enters a "digital intermediate" phase. Here, filmmakers perform color grading and add special effects while maintaining the "organic silver crystal" texture of the film. Professionals from IMAX use proprietary "DMR" (Digital Media
It is this immense potential that drives the industry. IMAX's VP of Post Production, Greg Ciaccio, notes that the IMAX format's theoretical resolution limit is . Yet, theoretical potential must meet practical reality. For many years, IMAX relied on an aging Northlight scanner that had passed its prime. The company has since invested in state-of-the-art Lasergraphics Director 13.5K scanners , which are currently used for its most critical archival projects.
