Full title and description

Ст ISO 2939-1986 (ISO 2939:1986) — Cinematography — Picture image area and photographic sound record on 35 mm motion-picture release prints — Position and dimensions. This entry refers to the ISO international standard as published in October 1986 and to Russian-language copies or national adoptions commonly labelled with the "Ст" prefix (e.g., "Ст ISO 2939-1986").

Abstract

ISO 2939:1986 defines the positions and dimensions of the picture image area and the photographic sound record on 35 mm motion-picture release prints intended for optical projection and related use. The standard gives layout and dimensional requirements to ensure compatibility between prints, projectors and sound reproduction systems.

Scope

This standard specifies the exact layout (positions and dimensions) of the picture image area and the photographic sound record on 35 mm motion-picture release prints used for optical projection. Its purpose is to ensure consistent placement of the image and sound tracks so that prints produced by different laboratories and equipment remain compatible with standard projection and sound playback systems.

Key topics and requirements

• Definition of the picture image area for 35 mm release prints (frame dimensions and placement on the strip).
• Specification of the position and width of the photographic (optical) sound record relative to the image frame.
• Dimensional tolerances to ensure mechanical and optical compatibility between prints and projection/sound equipment.
• References and alignment guidance to related cinematography standards governing projection and transmission formats.

Typical use and users

Used historically by film laboratories, cinema equipment manufacturers, post-production and mastering facilities, film archivists and standards committees to produce and check 35 mm release prints for theatrical distribution and preservation. Russian-language versions (Ст ISO 2939-1986) are primarily used by Russian-speaking technical staff, restoration specialists and organizations that maintain historical film collections.

Related standards

Standards related to image and sound layout for motion-picture film include ISO standards addressing 35 mm projection and transmission (for example, standards referenced in later revisions such as ISO 2907 and ISO 1223, and the updated ISO 2939 editions). ISO 2939 was later revised and newer editions (notably ISO 2939:2015) provide updated and expanded specifications.

FAQ

Q: What is this standard?

A: ISO 2939:1986 (presented here as Ст ISO 2939-1986 for Russian versions) is an ISO international standard that defines the position and dimensions of the picture image area and the photographic (optical) sound record on 35 mm motion-picture release prints.

Q: What does it cover?

A: It covers layout, dimensional specifications and tolerances for the image frame and the photographic sound track on 35 mm theatrical release prints to ensure compatibility across production and projection equipment.

Q: Who typically uses it?

A: Film laboratories, projection-equipment manufacturers, cinema technicians, archival and restoration specialists, and standards organizations—also Russian-speaking practitioners when using the Ст ISO (Russian) edition or translation.

Q: Is it current or superseded?

A: The 1986 edition has been withdrawn in the ISO lifecycle and later revised; ISO editions published after 1986 (including the 2015 edition) provide the current specifications. Users should refer to the latest ISO 2939 edition for current requirements.

Q: Is it part of a series?

A: Yes. ISO 2939 sits within ISO/TC 36’s series of cinematography standards that define film formats, projection and sound record placements; it cross-references related standards covering projection formats and sound-to-picture displacement.

Q: What are the key keywords?

A: 35 mm, picture image area, photographic sound record, optical sound, release prints, dimensions, cinematography, ISO 2939, Ст ISO 2939-1986.
