YouTube AI video detector: labels from Content Credentials
YouTube shows a “Captured with a camera” disclosure when a video carries unedited C2PA 2.1 or later credentials, and carries forward altered-or-synthetic disclosures from creators and from C2PA credentials that say a video was AI-made, so YouTube’s labels are platform observations derived from records that a downloaded or re-encoded copy will not contain.

Content Credentials found
A signed manifest describes how the file was made.
Signer, recording tool, actions and the signature check result are reported separately, so you can weigh each one.
Open the Content Credentials checker →What YouTube documents
YouTube’s help centre explains that “Captured with a camera” appears in the “How this content was made” section when the creator used capture tools with C2PA support version 2.1 or higher and the video’s sound and visuals were not altered; saving through apps that do not support C2PA breaks the chain. A separate page describes altered-or-synthetic disclosures, which creators must add for realistic AI content and which YouTube carries forward from Content Credentials 2.1 or higher indicating the entire video was AI-made.
YouTube also notes that unlabelled authentic content exists, because the label depends on supported tools.
What isGenAI shows for a YouTube video
YouTube streams are re-encoded, and a downloaded stream carries none of the uploader’s credentials. If you have the uploader’s original MP4 or MOV, the C2PA checker validates its manifest and the video metadata viewer reads its headers. Frames extracted with the video frame extractor are new images that can be matched by fingerprint in the AI image detector.
isGenAI does not score the pixels of a video or a frame.
What to do instead
Expand the description and read “How this content was made”; note the disclosure as a platform observation. Ask the creator for the original export when the file matters. The Sora page explains a vendor whose videos carry credentials YouTube can read.
A missing disclosure is not proof that a video is authentic.
How to check an image from this platform
- Note the platform’s own label or credential icon on the post before you download anything; it does not travel with the file.
- Ask the poster for the original file, or trace the first upload. A platform download is a re-encoded copy on most services.
- Upload what you have to the AI image detector and read the report. A stripped copy returns “no evidence found” honestly.
- Use the matching-copy check: a hash or perceptual fingerprint match can tie the stripped copy to an original that still carried records.
Frequently asked questions
What does “Captured with a camera” on YouTube mean?
The creator used a capture tool with C2PA 2.1 or higher and the video’s sound and visuals were not altered, per YouTube’s help centre. Edits or non-supporting apps break the chain.
Does YouTube label AI-generated videos?
Creators must disclose realistic altered or synthetic content, and YouTube carries forward disclosures from C2PA 2.1 credentials that say the whole video was AI-made.
Can isGenAI check a video downloaded from YouTube?
A downloaded stream is re-encoded and carries no credentials. Check the creator’s original file in the C2PA checker instead.
Does no label mean a YouTube video is real?
No. YouTube states that authentic content can lack the label and disclosures depend on creators and supported tools.
