Key standards
Visual physical commonsense (V-PC)
- A train departs the station platform with continuous forward motion, shrinking naturally in the frame as the clip progresses.
Audio physical commonsense (A-PC)
- A train whistle is clearly audible near the platform and grows steadily weaker as the train moves farther down the tracks.
Cross-modal physical commonsense (AV-PC)
- The decrease in whistle loudness corresponds to the train's visibly increasing distance from the platform.
