This Veo 3.1 motorcycle clip is detected as 94% fake

A creator on X shares their workflow masterpiece: a hyper-realistic video of a guy riding a motorcycle, openly stating it's built with Z-Image Turbo, Nano Banana Pro, and animated by Google's latest — Veo 3.1. It's a stunning showcase of where AI video is headed. But here at isFake, we had a different job. Our challenge is to always stay up to date with the newest Gen AI models. So can isFake AI video checker detect this Veo 3.1 clip?

We ran it through our AI video detector. The result was a definitive 94% AI-generated score. And even if it’s hard to notice the newest AI creations, our video detection tool stays confident to protect you. Additionally, with our frame-by-frame analysis and a complex report on detection results, you get the full image of whether the video is AI-generated or not.

How the detector keeps up with next-gen AI

  • The detector scans each frame for inconsistencies in texture, lighting, and physics that are invisible at full speed.
  • It flags subtle flickers or inconsistencies in movement between frames, a common hurdle for generative models.
  • It also identifies unrealistic physical interactions, like how light glints on the helmet or how the bike's weight shifts, which don't follow real-world physics.
Facing a model like Veo 3.1 isn't about looking for obvious glitches. It's about finding the microscopic digital DNA that all synthetic video shares, no matter how polished. Our detector is built to find exactly that.
