Cinematography. Time and control code for 24, 25 and 30 frames per second motion-picture film systems. Specifications
This document specifies digital code for mats and modulation methods for motion-picture film to be used for timing control editing and synchronization purposes. This document also specifies the relationship of the codes to the motion picture frame.
Two types of code are described in this document. The first type Type C is a continuous code which is very similar to the continuous code specified in IEC 60461. This type of code can be used in situations where the film is moving continuously at the time of both recording and reproduction.
The second type of code Type 8 is a non-continuous block-type code composed of blocks of data each complete in itself with gaps between the blocks. It is designed so that the code can be recorded and played back on equipment with intermittent film motion but still be decoded with the same type of electronic equipment used to read the Type C or continuous time code.

Frequently Asked Questions about BS ISO 9642:2020
When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.
Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
If you have an extensive portfolio of standards, we recommend using a professional standards management tool. With effects 2.0, you can manage your standards centrally and efficiently. You can optimise your procurement processes and benefit from an integrated information and subscription service. This ensures you are always up to date and never miss any relevant developments.
