General Information

Overview
ISO 1787:1984 is an international standard published by the International Organization for Standardization (ISO) that details specifications for the usage of 8 mm Type S motion-picture film in cinematography cameras. This standard specifically addresses the positioning of the emulsion, the frame rate of exposure, and the orientation of the exposed image area in 8 mm Type S film cameras. Designed to ensure consistency and quality in film production, ISO 1787:1984 harmonizes camera operations and film handling across manufacturers and countries.
The standard was developed by ISO Technical Committee ISO/TC 36, which specializes in cinematography, and it replaces the original 1972 edition, reflecting updates to meet evolving technological and industry requirements.
Key Topics
Emulsion Positioning
The emulsion layer of the 8 mm Type S film must be positioned facing the camera lens during exposure, except in specialized processes. Correct emulsion orientation is critical to capture clear, properly exposed images.Frame Rate of Exposure
- For silent (no sound) films, the standard frame rate is 18 frames per second (fps), which is optimal for typical projection speeds.
- For films containing a photographic sound record, the frame rate must be 24 fps.
- For magnetic sound recordings, the frame rate can be either 24 or 18 fps.
- For television broadcasting, exposure at 25 fps is recognized, reflecting broadcast standards in various regions.
Film Orientation and Positioning
The standard specifies the orientation of the exposed area as seen from inside the camera looking toward the lens. It also provides guidance on the use of perforations for precise film positioning, improving image steadiness and registration.Additional Film Handling Guidance (Annex)
Suggestions for preferred positioning using specific perforations are included to enhance steadiness and reduce image jitter in cameras and projectors.
Applications
ISO 1787:1984 is primarily applicable to cinematographers, film camera manufacturers, and film processing facilities working with 8 mm Type S motion-picture film. Practical benefits include:
Camera Design and Manufacturing
Ensures cameras are built to internationally consistent specifications, enabling compatibility with 8 mm Type S film stock.Film Production Consistency
Standardizing frame rates and emulsion positioning helps filmmakers achieve uniform image quality and projection reliability.Sound Film Recording
Assists sound engineers and filmmakers in selecting correct exposure rates for integrating audio with visual film elements.Broadcast Compatibility
Supports compatibility with television systems through recognition of alternative frame rates used in broadcasting.Film Projection and Preservation
Facilitates consistent film projection and archival processes by aligning with projector usage standards.
Related Standards
ISO 1787:1984 complements several other ISO standards related to 8 mm Type S film, including:
- ISO 1700: Cinematography - 8 mm Type S motion-picture raw stock film - Cutting and perforating dimensions
- ISO 1781: Cinematography - Projector usage of 8 mm Type S motion-picture film for direct front projection
- ISO 3645: Cinematography - Image area produced by 8 mm Type S motion-picture camera aperture and maximum projectable image area - Positions and dimensions
These related standards collectively cover film stock specifications, projector compatibility, and image area dimensions, offering a comprehensive framework for 8 mm Type S cinematography.

Foreword
IS0 (the International Organization for Standardization9 is a worldwide federation of
national standards bodies (IS0 member bodies). The work of developing International
Standards is carried out through IS0 technical committees. Every member body
interested in a subject for which a technical committee has been authorized 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.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council.
International Standard IS0 1787 was developed by Technical Committee ISO/TC 36,
Cinematography.
This second edition was submitted directly to the IS0 Council, in accordance with
clause 6.11.2 of part 1 of the Directives for the technical work of ISO. It cancels and
replaces the first edition (i.e. IS0 178749729, which had been approved by the
member bodies of the following countries:
