YouTube's Altered or Synthetic Content Label: What Triggers It and When You Can Change It

YouTube adds its AI label in three ways: you disclose it, the file carries C2PA metadata, or YouTube's own systems detect that the video is AI-generated or altered. YouTube says a label that came from C2PA metadata can not be adjusted after upload, so what is in the file matters before you publish. Removing metadata does not affect YouTube's detection or your duty to disclose realistic AI content.

What the label is called now

Many creators search for this as the "altered or synthetic content" label. YouTube's help page is now titled "Disclosing use of GenAI content" and refers to an AI label (YouTube Help). The rule behind it is the same idea: YouTube requires creators "to disclose AI-generated or altered content that seems realistic".

YouTube's examples of what needs disclosure include content that makes a real person appear to say or do something they did not do, and content that alters footage of a real event or place.

The three ways the label gets applied

• Your disclosure. During upload, in the Attributes section under AI use, you choose Yes if the video meets the disclosure requirements or No if it does not (YouTube Help).
• The file or the tool. YouTube says it may automatically apply an AI label for content made using its own GenAI tools and for "content that contains C2PA metadata".
• YouTube's detection. It may also label "content that our internal systems detect is AI generated or altered". YouTube said that starting in May 2026 it is "rolling out new internal signals to help identify AI-generated content" (YouTube, May 27, 2026). The pages we read do not say how those systems work.

Which labels you can change after upload

YouTube says creators can change the AI disclosure in most cases by selecting No in the AI disclosure survey under Attributes in YouTube Studio. If you believe your video was wrongly identified as AI-generated, that is where you update it (YouTube).

There are exceptions. The help page says content made with YouTube's AI tools, content containing C2PA metadata, and content labeled after manual review can not be adjusted (YouTube Help). The May 27, 2026 post says disclosures stay permanent for content created with YouTube's own AI tools, like Veo or Dream Screen, and for content containing C2PA metadata that indicates it was fully generative AI.

What the file has to do with it

C2PA metadata, also called Content Credentials, is a signed record that some cameras, editors and AI tools write into a video file. It is the one trigger on YouTube's list that travels inside your file, and it is one of the cases where the label can not be adjusted later. So it is worth knowing whether your file carries one before you publish.

You can check for free. Drop the video into the scanner below. It reports Content Credentials when they are in the file, and whether the credential says the video was made with AI. The file is not uploaded.

A credential is not only an AI marker: cameras and editing apps can write one too. The C2PA in video guide explains where the credential sits and what removing it changes. For every AI signal a video file can carry, see the guide to removing AI metadata from video.

What cleaning the file does not change

• YouTube's own detection, which its help page lists separately from C2PA metadata.
• Your duty to disclose realistic AI-generated or altered content.
• A label on a video made with YouTube's own AI tools.
• A watermark in the content itself, such as Google's SynthID.

Removing metadata is a way to control what your file says about your tools, dates and location. It is not a way around a disclosure you owe.

What does not need disclosure

YouTube says creators "don't need to disclose non-realistic content that's made with AI, or edits to realistic content that are minor". Its examples of what needs no disclosure include beauty filters, caption creation, idea generation, and cloning your own voice for voice overs or dubs (YouTube Help).

Monetization and reach

YouTube's help page says "disclosing AI content alone won't limit a video's audience or impact its eligibility to earn money". Its May 27, 2026 post repeats it: "a disclosure label alone does not change how a video is recommended or whether it's eligible to earn money".

The risk is on the other side. YouTube says creators who consistently choose not to disclose may be subject to "penalties from YouTube, including removal of content or suspension from the YouTube Partner Program".

Where the label shows, including Shorts

On long videos, "the label will now appear directly below the video player, above the description". On Shorts, it "will appear as an overlay on the video itself" (YouTube, May 27, 2026).
