YouTube 'Info from' under an AI label: what the signing authority is

The 'Info from' line under a YouTube disclosure names the signing authority: the party that validated the information inside the video's secure Content Credentials (C2PA). YouTube's help page says Content Credential disclosures often include that attribution, and when they do, you see 'Info from' beneath the disclosure. It does not appear on a label that came only from your own answer in YouTube Studio.

That distinction decides what you can do as a creator. If you generate a clip with a tool that signs its output, the signer's name can travel with the file. If you export from a tool that does not sign, YouTube has no signer to name, so the label comes from your 'AI use' answer or from YouTube's own detection.

Where the label comes from

The YouTube help page on 'How this content was made' lists three routes into a 'Made with AI' disclosure. The table keeps them apart, because only one of them can carry a signer.

What this means for a Sume export

Sume's video generation and trim docs describe the files and the job fields. They do not describe embedding or preserving Content Credentials, so do not plan on an 'Info from' line for a file that came from Sume. Plan on the manual route: answer the AI question yourself when the clip is realistic.

Trim is also a re-encode by default. The trim docs say precision: exact is a frame-accurate re-encode with libx264, and the result is a new artifact, never the source. A new file is a new file; any provenance data on the old one is not something the docs promise to carry over.

Steps

• Decide per clip whether it is realistic AI footage, using the examples on the GenAI disclosure page.
• In YouTube Studio, open the Attributes section and set 'AI use' to Yes or No.
• After upload, open the video and read the expanded description's 'How this content was made' section to see which label YouTube applied.
• If you see 'Info from', the label came from signed Content Credentials, not from your answer. Treat it as fixed.
• Record the clip's job id and your answer in your own log so the choice is auditable later.

Caveats

The help page says YouTube may also use Content Credentials to carry forward other disclosures about how content was made, so the section can hold more than 'Made with AI'. It also notes that YouTube can proactively apply a label to undisclosed content that creators will not have the option to remove. Missing 'Info from' therefore does not mean unlabeled, and an unwanted label may not be removable if it came from credentials or review.
