🎬 Prompt:

Extreme macro close-up at cutting-board height; 100mm macro lens, f/2.8 ultra-shallow depth of field; slow macro glide (only a few millimeters) with a gentle push-in; micro focus pulls to keep the knife edge, contact point, and crack front sharp; 4K photorealism, 60fps, ultra-detailed surface micro-scratches and particle rendering. Subject: Well-groomed human hands with clean trimmed nails, no jewelry; steady, careful grip on a stainless-steel kitchen knife with a clean polished bevel. A rock-like block with a cool frosted, glass-like surface (translucent, milky highlights), subtle edge bloom, and faint internal inclusions; placed on a wooden cutting board with visible end-grain texture. Action: One continuous, very slow straight cut from top to bottom through the frosted glass-like rock; the material shows soft, squishy deformation at the contact point, then stretches and fractures; the cut line gradually opens to reveal denser interior grain, pores, and layered micro-structures; tiny translucent chips, powdery grit, and fine shavings fall and scatter onto the cutting board; both halves separate slightly and settle. Context: Bright natural daylight coming from one side (window key light) creating crisp directional highlights and soft shadow falloff across the frosted surface and wood grain; clean minimal background with no clutter. Style: Photorealistic macro ASMR; calm intimate mood; natural color grade, clean whites, cool frosted tones contrasted with warm wood; minimal glare, high texture fidelity. Audio: Close-mic ASMR only: muted metallic scraping synced to blade movement, soft granular grit and tiny chips landing on wood; no background noise, no music. NO SUBTITLES
