IS THIS VIDEO REAL?

AI video generators leave detectable patterns in the files — different from how real cameras encode footage. Upload an MP4 or paste a URL and we'll compare its fingerprint against a curated corpus of real and fake samples.

// no file selected — engage detector is disabled

// the video is NOT stored. only encoder metadata, file hash, and the result.

// step_01
Extract

Regex over the raw bytes pulls H.264/x264 settings — `bframes`, `ref_frames`, `subme`, `keyint`, codec year, and ~25 others.

// step_02
Compare

Each field is checked against statistical thresholds derived from a real vs fake corpus. Mismatch → rule triggers.

// step_03
Verdict

FAKE if any rule triggers; confidence = % of rules that fired. Every rule is shown so you can judge the reasoning.
