    "body_text": "Generated video can look plausible frame by frame while buildings bend and camera motion collapses into cuts. Video Geometry Corrector treats that as a repair problem. The team creates synthetic pairs by distorting real camera-motion clips, then trains a video-to-video model to recover the consistent target with optical flow as an auxiliary cue. Across pose-conditioned and prompt-driven tests, the authors report improved geometry for multiple source generators, with larger backbones extending the effect. Because the supervision is synthetic and the evidence is benchmark-based, the work does not establish universal correction. It does show a modular path for improving geometric consistency without retraining every generator.",
