| "caption": "Visual caption: The clip consists of a single, continuous close-up shot of a person's hands hammering a nail into a plain, light-colored indoor wall. The camera is positioned at a slight upward angle and exhibits minor handheld shake. The person, wearing a light grey long-sleeved garment, uses their left hand to hold a small nail steady against the wall. Their right hand wields a hammer with a wooden handle and a dark metal head. The action begins with the hammer striking the nail repeatedly. The person continues to hammer, driving the nail deeper into the wall. A shadow of the hammer and the person's right hand is cast on the wall to the right of the nail. A small, rectangular vent or fixture is partially visible in the upper left corner of the frame. The lighting appears somewhat dim and warm.\nAudio caption: The audio consists entirely of sound effects and ambient room tone, with no speech or music present. The dominant sound is the rhythmic, metallic striking of a hammer hitting a nail. The sequence begins with a few lighter, sharper taps. As the clip progresses, the hammering becomes louder, more forceful, and slightly deeper in pitch, indicating the nail being driven further into the wall. The strikes occur in a steady, repetitive pattern. Faint, indistinct background noise or room tone is audible beneath the hammering.", |
| "edit_prompt": "Apply a slow-motion effect to the entire hammering sequence; visually slow down the hammer strikes and stretch the hammering sounds, slightly lowering their pitch.", |
