Video Deepfake Detector

Drop an MP4 / WebM. Aggressive mode scans every frame across the full video, runs the image ensemble on each, and inspects the muxed audio track with our voice DSP.

Scan mode

Aggressive video scans the full video frame-by-frame; other media uses the selected ensemble mode.

Detection sensitivity

50 · Balanced

Strict50 · Balanced (default)High

Frames / images scoring ≥ 50% are flagged as fake. Lower the slider to reduce false positives; raise it to catch borderline cases.

Detector diagnostics

Generates a few synthetic test clips in-browser and runs the full video pipeline against each to confirm the detector behaves consistently. No uploads.

Camera-like (real)

Expect: authentic

Gradient + moving subject + broadband sensor noise — should look authentic.

AI-smooth (synthetic)

Expect: suspicious

Soft, low-frequency, no sensor noise, narrow histogram — typical AI render.

Static-loop (synthetic)

Expect: suspicious

Frames barely change — temporal consistency should flag it.

Pass criteria: "authentic" clips score < 55%, "suspicious" clips score ≥ 55%. These are synthetic stress tests, not real deepfakes — they verify the pipeline reacts to the right pixel/temporal signals.
