Overview
ISO 71:2014 - Cinematography - specifies the positions and width dimensions for a 16 mm negative monophonic photographic sound record on 16 mm, 35/16 mm and 35/32 mm motion‑picture film. The standard is intended for preparation and printing of 16 mm release prints and defines how the optical sound track is placed relative to the film reference edge, including the direction of film travel and emulsion orientation.
Keywords: ISO 71:2014, cinematography standard, 16 mm negative, photographic sound record, motion‑picture film, sound track positions, dimensions.
Key Topics
- Scope: Applies to 16 mm negative monophonic photographic sound records on 16 mm, 35/16 mm and 35/32 mm film formats intended for printing 16 mm release prints.
- Positioning: Defines reference edges, directions of film travel (A and B winds), and the location of the sound record for single‑ and dual‑format film (Figures 1–3).
- Dimensions: Numeric dimension values for the sound record geometry are provided in Table 1. Representative dimensions given in the document include:
- A ≈ 15.20 mm
- B ≈ 2.03 mm
- C ≈ 14.48 mm
- D ≈ 30.43 mm
- E ≈ 16.02 mm (See ISO 71:2014 for exact tolerances and figure references.)
- Emulsion orientation: Figures show the film with the emulsion facing the observer and note typical wind directions for recording.
- Technical drawings: Figures 1–3 illustrate single 16 mm and dual‑format 35 mm arrangements; Table 1 lists dimension tolerances.
Applications
ISO 71:2014 is used by:
- Film laboratories and optical printing houses for alignment and quality control when creating 16 mm release prints from 16 mm negatives.
- Post‑production and sound departments that prepare negatives for optical soundtrack printing or reformatting between 16 mm and 35 mm stocks.
- Equipment manufacturers (optical soundtrack printers, film perforators and scanners) that require standard track placement and widths.
- Archivists and restorers ensuring historical material is reproduced accurately and compatible with legacy projection/printing systems.
- Standards and compliance teams confirming that material meets international cinematography specifications.
Practical benefits include consistent soundtrack placement for reliable duplication, predictable optical reading by soundtrack readers, and interoperability between film formats and printing workflows.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
