C2PA sample files for IPTC Video Metadata Hub

The C2PA Specification allows for metadata to be added to image or video files using an IPTC Photo and Video Metadata assertion.

The files in this directory demonstrate how IPTC Video Metadata Hub metadata properties can be embedded in video files using this specification.

How the video files were created

The metadata was added to the MP4 files using the open source c2patool command-line tool created by the Content Authenticity Initiative.

For example, the first file was created using this command:

c2patool park-bench-sunset-original.mp4 -m minimal-iptc-vmh-assertion.json -o park-bench-sunset-c2pa-min-vmh.mp4


Original file - with no added metadata
Video file: park-bench-sunset-original.mp4
Assertion created using the IPTC Video Metadata Hub Generator tool
Assertion JSON file: test-generator-assertion.json
Video file containing IPTC metadata embedded using C2PA: park-bench-generator-assertion.mp4
Verify with the contentcredentials.org tool
Minimal IPTC Video Metadata Hub assertion (using only core properties)
Assertion JSON file: minimal-iptc-vmh-assertion.json
Video file containing IPTC metadata embedded using C2PA: park-bench-sunset-c2pa-min-vmh.mp4
Maximal IPTC Video Metadata Hub assertion (using every possible property)
Assertion JSON file: maximal-iptc-vmh-assertion.json
Video file containing IPTC metadata embedded using C2PA: park-bench-sunset-c2pa-max-vmh.mp4
