IPTC Video Metadata Hub
Recommendation 1.5

Approved by the IPTC Standards Committee on 4 October 2023. Available at www.iptc.org/std/videometadatahub/recommendation/1.5

Specification

Properties

The Video Metadata Hub’s set of metadata properties includes:

• ~ 20 properties describing what can be seen and heard in the video
• ~ 15 properties providing rights related information
• ~ 15 properties for administrative purposes
• ~ 25 properties covering technical characteristics
• ~ 15 structures of properties which are used for properties listed above

Each property is defined with:

• a name
• a definition of its semantics
• a basic data type
• a definition how often it may occur in the metadata about a piece of video

Technical Implementation

All Video Metadata Hub properties can be expressed by these technical standards:

• XMP – for metadata embedded into the binary video file
• JSON – for a stand-alone and light-weight exchange of metadata, e.g. by APIs
• C2PA – all IPTC Video Metadata Hub properties can be embedded into C2PA assertions using the IPTC Photo and Video Metadata assertion

User Guide

We have created a detailed guide to using and implementing IPTC Video Metadata Hub which 

Example video files with embedded metadata

A short video about an IPTC event, all properties defined by a version of the Video Metadata Hub are populated and embedded by XMP. The property values reflect the property name to help sorting out what is displayed in a user interface. The video may be downloaded (8 MB) and investigated:

• for Recommendation 1.0
• for Recommendation 1.1
• for Recommendation 1.2
