Generated clip audio and video can be recognized as AI in two ways: a visible overlay on the video, and machine-readable marks on the files. This page describes those marks.

​
What we always apply

These marks are on every take. They cannot be turned off. The AudioSeal and VideoSeal payload is 0x414C (ASCII AL, Akapulu Labs). The watermarks stay in the media if someone copies the file without the C2PA box. C2PA uses intent CREATE and digital source type trainedAlgorithmicMedia. The files are signed with an Akapulu Labs ES256 certificate. Download the public root and verification notes from Content Credentials. Readers that do not have our root (Photoshop, default c2patool) will report signingCredential.untrusted until it is added as a user trust anchor. The signature still proves the bytes were not edited after we signed them.

​
Visible labels (optional)

On render an on-screen card can also be overlaid on the video:
  • show_ai_label — This is AI
  • show_logo — Made by plus the Akapulu Labs logo
Both default to true. show_ai_label can be false on any plan. show_logo: false needs Starter or higher. We recommend leaving show_ai_label as true so people watching can tell the clip is AI-generated. Some places, including the EU, have rules about disclosing AI-generated media. Turning the on-screen label off does not remove AudioSeal, VideoSeal, or C2PA. How to set the flags is in Workflow. Also: Overview · Python example
