Video Physics Audit checks whether the motion in a video is consistent with real-world physics. You upload a short clip, or try a sample. Muse Spark looks at a few frames, names the moving object and asks only what it cannot see: is the camera fixed, is it slow motion, how big is the object. SAM 3.1 tracks the object frame by frame, by name or by a point you tap. Deterministic Python code, never a model, fits the path and compares it with the motion model, correcting for camera shake and for motion toward the lens. The answer is always one of three: consistent, inconsistent, or cannot judge, with the reason. It never says a video is fake. In tests with rules fixed in advance, real clips that fit the filming rules came out 4/4 consistent and AI-generated clips 4/4 inconsistent; on 57 harder clips from six video models, no AI clip was judged consistent.
