– Edits that break the chain of origin or make it impossible to trace the video back to its original source. For example, if you capture an image with C2PA metadata and then save it to your phone's photo album, which does not support C2PA v2.1 or later, this may break the chain of origin.
– Significant changes to the core characteristics or content of the video, including audio and visual content.
– Edits that cause the video to be incompatible with C2PA standards (version 2.1 and above).
