A car accelerates rapidly toward the camera on an open road, clearly getting closer frame by frame; instead of the engine becoming louder and more forceful, the sound steadily fades and softens as the car approaches.

Key standards
Visual physical commonsense (V-PC)
- A visible car accelerates continuously toward the stationary camera on an open road, with the car getting visibly closer frame by frame.
Audio physical commonsense (A-PC)
- A continuous engine sound with the character of a real car engine is audible throughout the clip.
- The engine sound steadily fades and softens as the clip progresses, becoming quieter rather than louder.
Cross-modal physical commonsense (AV-PC)
- The progressive decrease in engine sound loudness corresponds to the visibly decreasing distance between the car and the camera.
