Is this video AI-generated?

Paste a link or upload a file. Four independent detection passes run simultaneously and combine into a single forensic verdict.

How the detection engine works
01Gemini Video Analysis

The full video is uploaded to Gemini 2.5 Flash, which watches it like a human reviewer — checking for unnatural motion, temporal flicker, inconsistent lighting, and AI-specific artifacts.

02Frame-by-Frame Inspection

6 keyframes are extracted and sent to Gemini individually. Each frame is checked for skin smoothness, hair coherence, hand anatomy, and face boundary blending.

Face swapsDeepfakesImage-to-video AI
03Pixel-Level Forensics

ffmpeg runs five low-level analyses — PSNR inter-frame comparison, YDIF luma variance, freeze detection, motion vectors, and codec/bitrate anomaly checks. No external API needed.

Static background compositingFrozen framesBitrate oddities
04Avatar / Talking-Head Detector

A dedicated pass targeting AI avatar tools. Looks for the hallmark pattern: fully static background (YDIF ≈ 0) with a moving, speaking face overlaid. Jewelry and hair that don't move are also flagged.

If Avatar Detector or Pixel Forensics fire strongly, they override a REAL verdict from Gemini — this catches HeyGen-style videos that fool visual analysis alone.

AI detection is probabilistic — results are not guaranteed. Videos are sent to Google's servers via Gemini AI and deleted immediately after analysis.
