Two sport clips per round · Pick the real one · Kling 3.0, Sora 2, Veo 3
About This Quiz
Each round shows two short sport video clips side by side — one is real footage from an actual match or event, the other was generated entirely by an AI model from a text prompt. Your job: pick the real one. Sports footage is uniquely challenging because AI must simulate human biomechanics, ball physics, and crowd environment simultaneously. After each answer, both clips keep looping so you can study what gave the AI away.
AI Models Featured
Kling 3.0 — Kuaishou
Highly realistic athlete motion and fast-paced action sequences. One of the hardest sport generators to detect.
Sora 2 — OpenAI
Strong ball trajectory physics and player movement coherence. Struggles with fast multi-player interactions.
Veo 3 — Google DeepMind
Broadcast-style framing with accurate stadium lighting. Main weakness: fast-motion limb detail.
Seedance 1.5 Pro — ByteDance
Smooth natural-looking athlete motion. Particularly strong on individual sports like tennis and athletics.
Tips for Spotting AI Sports Footage
- Ball physics — trajectories, spin and bounce that look too perfect or pass through surfaces briefly
- Crowd detail — AI crowds are often blurry, repeating, or made up of copy-pasted figures
- Fast-motion limbs — arms and legs that blur oddly, briefly multiply or snap back unnaturally
- Surface texture — grass and turf can shimmer or ripple around moving feet in AI video
- Inertia and weight — real athletes have momentum and micro-corrections; AI movement feels too smooth
