Key standards

Visual physical commonsense (V-PC)

  • The ice cream truck drives steadily down the street with continuous forward motion, shrinking naturally in the frame as the clip progresses.

Audio physical commonsense (A-PC)

  • A recognizable ice-cream-truck melody plays from the truck and fades steadily quieter as the truck drives away.

Cross-modal physical commonsense (AV-PC)

  • The decrease in jingle loudness corresponds to the truck's decreasing visible size in the frame.
