Visual Forensics Guide

Common signs of video face swaps

Face-swap software maps a source face onto a target actor, leaving telltale boundary and blending defects.

01

Jawline & Hairline Boundary Blurring

Software struggles to blend the synthetic facial mask into real hair and ears, producing a subtle soft-focus halo along the jaw and hairline.

02

Mismatched Ambient Illumination

The lighting on the swapped face often originates from a different direction or color temperature than the actors neck, chest, and background.

03

Pupil & Iris Gaze Freezing

Synthetic eyes frequently exhibit erratic micro-movements, mismatched pupil dilation, or reflections that fail to match the scene light sources.

04

Micro-Jitter During Occlusions

When hands, cups, or microphones pass in front of the face, face-swap algorithms momentarily glitch, flicker, or warp around the obstructing object.

How the verification engine works

1. Ingest Media
Upload a video clip, full-resolution photo, or paste any direct media link.
2. Multi-Layer Scan
Scans for frequency patterns, flow-matching artifacts, and generative diffusion noise.
3. Instant Verdict
Clear Real vs. AI verdict with confidence scores, detected generator model, and reverse matches.

Frequently Asked Questions

3 Answers
How do deepfake face swap tools work?
Tools like DeepFaceLive, FaceFusion, and Roop track facial landmarks in every frame and warp a digital mask of the target identity over the real actor.
Can face swaps be detected if the video is low resolution?
Yes. Low resolution is often intentionally added by scammers to mask blending seams, but neural frequency analysis detects compression edge discontinuities.
How can I test a suspicious video call match?
Ask the person to turn their head 90 degrees to show their profile or pass their hand directly in front of their face. Face-swap masks will visibly glitch.
