Verity Lab samples frames from a video and measures simple patterns: how much the picture changes between frames, how varied the texture is, and how heavily the video is compressed. The result is a rough indicator, not proof. It is not an AI-video detector and cannot say whether a video is real or fake.
Pick an MP4, MOV or WebM file, up to 500 MB.
The tool samples several frames and measures motion, texture and compression.
You get a score and three measurements with plain explanations.
Treat unusual patterns as a reason to look closer, then check where the video came from.
How much the picture changes from one sampled frame to the next.
How varied the fine detail is across frames.
Estimated bitrate, which shows how heavily a clip was compressed.
A score with notes on every measurement.
The video is analysed in your browser.
The page states what the score can and cannot tell you.
No. It measures simple frame patterns only. Screen recordings, animation and heavily compressed videos can look 'unusual' without being fake, and fake videos can look ordinary. Use it as a rough hint and always check the source.
No. It is analysed in your browser.
It combines three measurements into a rough indicator of unusual smoothness or compression. It is not a probability that a video is fake.
MP4, MOV and WebM files up to 500 MB that your browser can decode.
Reliable detection of manipulated media needs specialised models and expert review. This tool is a simple demonstration of frame statistics.
