Full title and description

Information technology — MPEG systems technologies — Part 16: Derived visual tracks in the ISO base media file format. This international standard defines a storage format for derived visual tracks and an initial base set of related transformation operations that enable interchange, editing and display of timed sequences of images produced by applying transformation operations to input still images or samples of timed sequences in the same presentation.

Abstract

This document specifies normative structures to describe transformation operations, how those operations link to input images or samples, and how to process the described operations to obtain a timed sequence of video frames (derived visual tracks). The format supports exchange and editing workflows for image-derived sequences within ISOBMFF-based files.

Scope

The standard defines a storage format and a base set of transformation operations for creating timed visual sequences (derived visual tracks) from input still images or samples of timed image sequences within the ISO base media file format (ISOBMFF). It specifies the normative box/structure elements used to describe operations, the linkage between operations and input data, and the processing rules required to materialize the resulting frames for playback or editing. The intent is to enable interoperable interchange and editing workflows for image-derived video content inside ISOBMFF files.

Key topics and requirements

• Definition of a storage format for derived visual tracks in ISOBMFF containers (structure/boxes for operation descriptions).
• A base set of transformation operations (described normatively) that can be applied to still images or image samples to produce timed sequences.
• Mechanisms to link transformation descriptions to specific input images or samples within the same presentation.
• Processing rules to instantiate the operations and generate the timed sequence of video frames for playback or export.
• Metadata and interoperability considerations to support editing, interchange and display within ISOBMFF-based ecosystems.

Typical use and users

Implementers of media file tools and libraries, multimedia application developers (editors, transcoding tools), device and player vendors, content production and post-production houses, and streaming or archival systems that need to represent, exchange or edit image-derived timed visual sequences inside ISO Base Media File Format (MP4/fMP4, HEIF, etc.) files. Developers will use the standard to ensure interoperable storage of transformation descriptions and to implement processors that materialize derived visual tracks.

Related standards

Relevant related standards and families include the ISO base media file format (ISO/IEC 14496-12 — ISO BMFF) which provides the container and box model that Part 16 extends, and other parts of the ISO/IEC 23001 (MPEG‑B) series addressing MPEG systems technologies (for example Parts 1, 7, 9 and others in the MPEG‑B family). Implementers should consider ISOBMFF (ISO/IEC 14496-12) and other MPEG systems parts when designing workflows that incorporate derived visual tracks.

FAQ

Q: What is this standard?

A: ISO/IEC 23001-16:2021 is an international standard that defines a format and processing rules for derived visual tracks in the ISO base media file format — i.e., timed video-like sequences produced from transformation operations applied to still images or image samples.

Q: What does it cover?

A: It covers the normative structures used to describe transformation operations, the way those operations are linked to inputs inside an ISOBMFF presentation, and the processing rules to obtain timed video frames from those descriptions. The goal is interchangeability and editability of image-derived sequences.

Q: Who typically uses it?

A: Software and tool developers (media libraries, editors, transcoders), device and player implementers, production/post-production facilities, and platform operators who need a standard way to store and process derived image sequences inside ISOBMFF-based files.

Q: Is it current or superseded?

A: ISO/IEC 23001-16 was published in November 2021 and is listed as published (Edition 1, 2021). There is no indication on the ISO record that it has been superseded as of its publication record. Users should check ISO/IEC and national body records for any subsequent amendments or revisions.

Q: Is it part of a series?

A: Yes — it is Part 16 of the ISO/IEC 23001 series (MPEG‑B — MPEG systems technologies). It is designed to work within the ISOBMFF ecosystem and alongside other MPEG systems parts.

Q: What are the key keywords?

A: Derived visual tracks; ISOBMFF; ISO base media file format; transformation operations; timed image sequences; MPEG systems.
