Check its source and provenance, corroborate material details independently, use detection tools only as supporting evidence, and document the editorial decision. No single credential, detector, or visual inspection can establish that a video is truthful and correctly contextualized.
What does it mean to fact-check an AI-generated video?
It means reviewing separate questions that are easy to conflate: where the file came from and how it was handled; whether there are signs of synthetic generation or manipulation; whether its claims and context are supported by evidence; and how it should be described to viewers. These checks can inform one another, but none substitutes for the others.

A video may be authentic in the narrow sense that it has not been altered since a documented point in its history, yet still be misleading because it is staged, mislabeled, or presented without context. Conversely, a video made with AI may depict a real event accurately. Treat the media’s origin and its factual assertions as distinct editorial questions.

Use a repeatable pre-publication review
- Define what needs checking. List the video’s material claims, the people or events it depicts, where and when it is said to have been made, and the context in which you plan to publish it. Consider the likely harm if viewers misunderstand the representation.
- Preserve and trace the source. Keep the original file and available source materials. Record who supplied them, when they were received, and what edits, exports, or other transformations are known. Avoid relying only on a copy downloaded from a social platform when a source file is available.
- Inspect provenance information. Check for Content Credentials or other available provenance signals. Record what the information reports and what portion of the file or production history it covers. Treat it as evidence about origin or history, not as a certificate that the scene or its claims are true.
- Corroborate claims independently. Verify relevant dates, locations, identities, and events against authoritative sources independent of the video. Use evidence appropriate to the claim, and do not use an AI-generated clip as the sole proof of its own assertions.
- Use detection carefully, if useful. A detector can provide an investigative lead, not a final verdict. Record the tool, the file or version tested, and the result. Do not present a score as a universal probability unless the tool’s calibration and test conditions justify that interpretation.
- Make and record the editorial decision. Describe the media accurately, disclose AI generation or manipulation when appropriate, and check the rules and platform policies that apply to the publication. Keep an audit trail of the source, checks, findings, unresolved uncertainty, decision, and disclosure.
What Content Credentials can—and cannot—establish
C2PA Content Credentials are designed to record provenance in a tamper-evident structure. The Coalition for Content Provenance and Authenticity (C2PA) explains that the standard complements media literacy, fact-checking, and digital forensics by providing infrastructure to record an asset’s provenance. The C2PA Content Credentials Explainer, version 2.2 describes that role; it does not make provenance a substitute for those other checks.

A credential may help establish information about an asset’s origin or recorded history. It does not by itself establish that the recorded assertions are true, that the video accurately depicts a real event, or that it is being shown in the right context. OpenAI likewise cautions that provenance signals do not guarantee content is accurate, unedited, legally owned, or presented in the correct context (“Provenance signals in OpenAI-generated content”).
Credentials are optional, so their absence alone is not evidence of deception. A missing credential may simply mean no credential was created, retained, or available in the copy under review. Report what is present and verifiable rather than treating presence or absence as a truth test.

How to assess AI-video detectors
Detection tools may flag indicators associated with synthetic or manipulated media, but their results can be wrong and depend on the media and conditions tested. A score is not automatically a probability that a clip is fake, and a result does not answer whether the video’s claims are accurate.

NIST’s SP 800-63A-4 concerns remote identity proofing, not general editorial practice. In that specific setting, NIST says automated media analysis should be tested against forged and genuine media and augmented by manual review to address detection errors. For newsroom or publishing review, that is a useful caution rather than a universal requirement: understand what a tool tested, how its performance was evaluated, and what a human reviewer can inspect.

When choosing among methods, compare the question each addresses—provenance, manipulation indicators, or factual claims—along with supported media and transformations, independently checkable evidence, known limitations, tested error rates, and the ability to inspect underlying evidence. Do not rank tools without current, comparable evaluation data.
How to describe the video to your audience
Be specific about what you know and what remains unresolved. Distinguish “AI-generated,” “AI-manipulated,” “verified source,” and “independently corroborated” rather than using them interchangeably. If the origin is uncertain, say so; do not convert a detector result or absent credential into a categorical claim.
Disclosure obligations depend on context, jurisdiction, and platform. The European Commission’s page on the Code of Practice on Disinformation describes labeling provisions for deepfakes and AI-generated or manipulated content. Check current requirements that apply where and how you publish; policies and rules can change.
