Runway detector

Was this video made by Runway?

Runway signs its files with Content Credentials. A file that still carries that signed record names the tool directly. The detector also reads the picture, and the page shows the per-generator rate with n for every Runway model tested.

How the check works

A Runway file that kept its signed record is confirmed by signature; the report shows the Content Credentials and names Runway directly. That is the strongest evidence.

Without the record, the detector judges the picture. The accuracy page lists Runway Gen-3 clips and other Runway models with their catch rates and sample sizes, updated with each test batch.

What the page will not say

A Runway file that a platform re-encoded may lose its signed record. The page says so and does not guess.

The detector reports the picture's evidence and any signed record it found. It does not run Runway's own tools, and the verdict is evidence, not proof.

Can I check a Runway video by pasting its link?

Yes. Paste the link and the detector fetches the video and runs it through the same pipeline as an upload. If the file still carries its signed record, the report names the tool directly. How the check works

What if the file has no signed record?

The detector judges the picture. Runway Gen-3 clips from the AIGVDBench test set showed a 7% likely-AI rate from the image alone, so a low score does not mean the video is real. The signed record is the reliable path. Per-generator rates
