In U.S. federal practice, the proponent generally must first authenticate the item—provide evidence sufficient to support a finding that it is what they claim it is. If an expert relies on an AI system to analyze or enhance it, the reliability of that expert’s methods is a separate question. State courts may apply different rules.
What does the party say the evidence is?
The court’s first task is to identify the claim being made about the exhibit. “This video is authentic” can mean several different things: that it is an original camera recording, an unaltered copy, an AI-generated illustration, a recording processed to improve its visibility, or an output from software that classified an image or video.

Those are not interchangeable. A party may acknowledge that an image was generated or enhanced with AI and offer it for a limited purpose. A different dispute arises when a party offers a recording as genuine and the opponent says it was fabricated or deceptively altered. Courts assess the item, the purpose for which it is offered, the foundation supporting it, and the law of the jurisdiction—not the label “AI evidence” alone.

How is a video authenticated?
In federal court, Federal Rule of Evidence 901(a) requires the proponent to produce evidence sufficient to support a finding that the item is what the proponent claims. Rule 901(b) lists examples of ways to do that, including testimony from a person with knowledge, distinctive characteristics, and evidence about a process or system. The examples are illustrative, not an exclusive checklist.
#1 Best Overall
Depending on what is disputed, relevant foundation might include testimony from someone who recorded or recognizes the video, information about where it came from, surrounding circumstances, or technical evidence about how it was created or handled. Rule 901 does not require one particular forensic test for every video.
Authentication is a threshold question, not a finding that every detail in a recording is true or every conclusion drawn from it is sound. A recording might be authenticated as the item its proponent says it is while its meaning, completeness, or weight remains contested. Conversely, proof that a video file exists does not, by itself, establish that it depicts the event or person claimed.
What if the other side says the video is a deepfake?
A court must consider the basis for the challenge as well as the foundation offered by the proponent. Saying “AI could have made this” is not the same as presenting evidence that this particular recording was fabricated. But the exact procedure and threshold for responding to a challenge depend on the governing law and the record in the case.

(M.H.), 2026 NY Slip Op 00825, the court considered a concern that images depicted virtual children. It described that concern as speculation on the record before it, where no concrete facts supported it, and observed that a proponent need not rule out every possibility inconsistent with authenticity. The decision is a jurisdiction- and record-specific example, not a nationwide rule that every deepfake challenge must meet the same test.
The decision also discussed a proposed federal Rule 901(c). That proposal was not an effective rule. In its May 17, 2026 report, the federal Advisory Committee on Evidence Rules described a working draft based on two principles: an opponent would need some evidentiary basis before obtaining an inquiry into fabrication, and a sufficient showing would lead to a higher authenticity standard for the proponent. The committee said an amendment was not warranted “for now.” Courts should not treat that draft as binding federal law.
Does authenticating AI-processed evidence prove that the AI analysis is reliable?
No. Authenticating the media and establishing the reliability of an expert’s AI-based analysis are distinct issues. A video may be shown to be the recording the proponent claims while an expert’s claim about what an AI system detected, reconstructed, or enhanced still needs a sound foundation.
Under Federal Rule of Evidence 702, the party offering expert testimony must establish, more likely than not, that the expert’s specialized knowledge will help the factfinder and that the testimony rests on sufficient facts or data, reliable principles and methods, and a reliable application of those methods to the case. Meeting Rule 901’s authentication threshold does not establish that an AI detector or enhancement system is accurate.
That distinction matters particularly when software is used to infer details not plainly visible in the original, such as identifying a person or reconstructing an obscured feature. The relevant question is not simply whether a tool uses AI; it is whether the expert’s method and its application are sufficiently reliable for the opinion being offered. The Federal Rules of Evidence do not make AI-generated evidence automatically inadmissible, nor do they make an AI output self-proving.
Can AI-enhanced video be admitted?
It can be offered, but enhancement may create its own dispute. A court may need to assess what the original footage shows, what the software changed or inferred, and whether an expert can explain and support the method. Those concerns differ from whether the original recording is authentic.
A 2026 article in the American Journal of Comparative Law, “Artificial Intelligence and Civil Justice: U.S. Practice, Policy, and Principles,” reports an exclusion of AI-enhanced video following expert testimony. The reported concerns included lack of peer review and reproducibility in the forensic video-analysis community, as well as confusion and unfair-prejudice concerns. The available account does not establish the case name, court, or jurisdiction, so it should not be treated as a broadly applicable holding or a guide to a particular court’s rule.
As with other evidence, the court’s analysis can involve more than authentication. Judicial-education materials from the National Center for State Courts discuss Rules 901, 902, and 104, as well as the roles of courts, juries, and extrinsic evidence. Whether an exhibit is admitted, what parts are permitted, and what weight jurors give it are separate questions governed by the facts and applicable law.

How the main issues differ
| Evidence or dispute | Main question | What the cited federal framework establishes |
|---|---|---|
| Recording offered as an original or copy | Is it what the proponent claims it is? | Rule 901(a) requires evidence sufficient to support a finding of authenticity; Rule 901(b) gives nonexclusive examples of foundation. |
| Recording alleged to be fabricated | What evidence supports the challenge, and what foundation supports the proponent’s claim? | The ordinary Rule 901 framework applies in federal court. The proposed deepfake-specific Rule 901(c) described in May 2026 was a working draft, not binding law. |
| AI-generated or AI-enhanced exhibit | What was generated or changed, and what is the exhibit offered to prove? | Authentication remains relevant; a disclosed AI process does not by itself settle admissibility or weight. |
| Expert opinion based on an AI system | Are the expert’s data, methods, and application reliable? | Rule 702’s expert-testimony requirements are separate from authentication under Rule 901. |
What federal courts have reported about deepfake disputes
The May 17, 2026 Advisory Committee report described limited reported experience in the Federal Judicial Center survey it discussed: 15 respondents said they had dealt with deepfake issues. That is a count of survey respondents, not 15 court cases, a national total, or an estimate of how often deepfakes appear in litigation. The cited federal material does not support a claim that courts routinely admit or exclude deepfake evidence.

What a party should clarify when offering or challenging a video
The legal questions become easier to assess when the parties are precise about both the item and the claim. For a disputed exhibit, the useful questions include:
- What is the exhibit? Identify whether it is an original recording, a copy, an AI-generated image, an enhanced version, or an automated system’s output.
- What is it offered to show? State the specific fact or inference the exhibit is meant to support.
- What foundation supports its identity and source? Identify available testimony, provenance, distinctive characteristics, process information, or other evidence relevant to the claim.
- What exactly is challenged? Distinguish an allegation of fabrication or alteration from a dispute about the source, the interpretation, or an AI system’s reliability.
- If an expert is involved, what supports the method? Address the data, principles and methods, and their application to the particular recording under Rule 702 in federal court.
These are questions for organizing the evidentiary dispute, not a universal checklist or guarantee of admission. The Federal Judicial Center’s May 2026 material, the federal evidence rules, and the New York appellate decision address different contexts; state law and case-specific procedure can change the analysis.
