Key standards
Visual physical commonsense (V-PC)
- Heavy curtains visibly draw across a closed window facing a busy street, completing a full closure.
- The street-facing scene is visible both before and after the curtains close.
Audio physical commonsense (A-PC)
- Clearly audible busy-street ambience is present before the curtains close.
- After closure, the street noise drops noticeably in both loudness and high-frequency content.
- The reduced sound level is sustained for the rest of the clip after closure.
Cross-modal physical commonsense (AV-PC)
- The drop in street-noise loudness and brightness aligns in time with the visible closing of the curtains.
