Key standards

Visual physical commonsense (V-PC)

  • A visible motorboat moves smoothly from left to right across the visible frame, traversing across the frame while the camera remains relatively stationary.

Audio physical commonsense (A-PC)

  • The engine sound carries the steady low puttering rhythm of a real small motorboat.

Cross-modal physical commonsense (AV-PC)

  • The engine puttering pans smoothly from left to right in the audio field, tracking the visible motion of the boat across the lake.
