Films exhibited with an aspect ratio wider than their original format are sometimes referred to as “open matte.” This presentation reveals image areas typically masked during theatrical release, often showing more picture at the top and bottom of the frame. For instance, a film shot in a 1.85:1 aspect ratio but projected in 1.78:1 (16:9) would reveal extra information at the top and bottom, resulting in an “open matte” presentation. This can be intentional, offering a fuller view as originally composed, or accidental, stemming from improper formatting during transfer.
Choosing between an open matte or original theatrical aspect ratio often involves artistic considerations and technical limitations. While the former might reveal previously unseen details enriching the viewing experience, it can also introduce unintended elements, such as boom mics or incomplete set pieces. Historically, open matte presentations were more common in the home video era due to the prevalence of 4:3 televisions. As widescreen displays became standard, preserving the original theatrical aspect ratio gained importance. Understanding the nuances of each presentation helps viewers appreciate the filmmaker’s intent and the technical challenges of film exhibition.
