# A surgery video that looks right but isn’t.

Agent contract: 1.2.0

When experts graded AI-generated surgical videos, the clips looked convincing but mostly failed on surgical logic, not picture quality — a caution for anyone trusting realistic AI video.

## The human problem

AI can now generate video that looks real, and people may assume realistic footage is also correct.

## The prior constraint

Visual quality alone does not establish whether a generated surgical video is surgically valid.

## AI’s actual role

Researchers built the SurgVeo benchmark and a “Surgical Plausibility Pyramid,” then had experts assess videos from the generative models Veo-3 and Wan2.2.

## The documented result

The authors report that “despite high visual fidelity, the majority of errors are surgical logic failures rather than visual quality deficits.”

## Why it may matter

It is a grounded reminder that realistic-looking AI video is not the same as trustworthy AI video — the surface can be convincing while the reasoning underneath is wrong.

## Limitations

A preliminary benchmark study reported in a peer-reviewed early-access paper; the paper notes clinical application “remains critically unexplored,” and the abstract reviewed by Bright does not give the number of videos or expert raters.

## Unresolved questions

Can generative video models be trained to respect surgical logic, and how would that be measured?
