Cinematography - Image area produced by 65 mm/5 perforation motion-picture camera aperture and maximum projectable image area on 70 mm/5 perforation motion-picture prints - Positions and dimensions

ISO 2467:2004 specifies, for 65 mm/5 perforation motion-picture cameras and projectors, the dimensions of the image area produced by the camera on the film and the maximum projectable image area as well as the image positions relative to the reference edge of the film, and the perforations used to position the film in the camera.

Overview

ISO 2467:2004 is an international standard published by the International Organization for Standardization (ISO) that defines the specific dimensions and positions of the image area produced by 65 mm/5 perforation motion-picture cameras, as well as the maximum projectable image area on 70 mm/5 perforation motion-picture prints. This standard is crucial for the cinematography industry, particularly in analog film production and projection, to ensure consistency and compatibility between camera apertures and projection surfaces.

The standard provides detailed specifications related to the positioning of the film image relative to the reference edge of the film and the perforations that align the film within cameras and projectors. ISO 2467:2004 was developed by the ISO technical committee ISO/TC 36 – Cinematography, with this edition being a minor revision of the earlier 1980 version.

Key Topics

• Image Area Dimensions: ISO 2467 specifies the exact measurements for the image recorded by 65 mm/5 perforation cameras, including maximum, minimum, and nominal sizes to maintain standardization in film production.
• Projectable Image Area: It details the maximum image area that can be projected from 70 mm/5 perforation motion-picture prints for consistent viewing quality.
• Image Positioning: Defines the relative positioning of the recorded image on the film, including angles between image borders and film reference edges, ensuring proper alignment during projection.
• Film Perforation Usage: Specifies which perforations on the film are used to position the film accurately in the camera and projector to prevent misalignment or double exposure.
• Reference Edge for Guiding: Recommends a reference edge on the film to serve as a guide for improved stability and alignment during projection and development processes.

Applications

ISO 2467:2004 is essential for filmmakers, film laboratories, and equipment manufacturers involved in the handling, processing, and displaying of large-format motion picture films. Key practical applications include:

• Camera Manufacturing: Ensuring that 65 mm/5 perforation motion-picture cameras produce image areas conforming to a known international standard, enabling interchangeability and consistency across different camera models.
• Film Printing and Processing: Provides film labs with precise cutting and perforation measurements critical for producing films compatible with large-format projectors.
• Projection Systems: Assists projector manufacturers and operators in setting up equipment to accurately display the maximum projectable image area on 70 mm prints, optimizing the viewing experience without image distortion or clipping.
• Film Restoration and Archiving: Enables restoration experts to maintain or recreate original image dimensions and positions when transferring or preserving 65 mm film footage.
• Cinematic Productions: Supports producers and cinematographers in maintaining artistic and technical quality standards, especially in premium formats like IMAX or other large-format presentations using 65 mm film.

Related Standards

• ISO 3023: Cinematography – Specifies the dimensions and perforations for blank 65 mm and 70 mm motion picture films, which complements ISO 2467 by detailing film stock specifications.
• ISO/TC 36 – Cinematography Standards: A suite of standards covering film formats, processing, and projection practices ensuring broad compatibility in the motion picture industry.
• Standards for 35 mm Film: Other ISO standards covering smaller format films provide foundational references for film perforation and image area standards.
• Digital Cinema Standards: While ISO 2467 focuses on analog large-format film, contemporary digital cinema standards address image dimensions and projection parameters for digital motion pictures.

By adhering to ISO 2467:2004, stakeholders in cinematography can achieve precise control over image dimensions and positioning on 65 mm and 70 mm film formats, thus supporting high-quality, reliable film production and projection. This standard helps maintain the technical integrity and historical continuity of large-format cinema technologies.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 2467 was prepared by Technical Committee ISO/TC 36, Cinematography.
This third edition cancels and replaces the second edition (ISO 2467:1980), of which it constitues a minor

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec la
Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
L'attention est appelée sur le fait que certains des éléments du présent document peuvent faire l'objet de droits
de propriété intellectuelle ou de droits analogues. L'ISO ne saurait être tenue pour responsable de ne pas avoir
