Cinematic ASMR macro video, in the style of a minimalist, high-end product commercial. The aesthetic is clean, hyperrealistic, and deeply satisfying. An extreme close-up (ECU) macro shot, completely static and locked-off. The camera angle is a slightly high, 45-degree tabletop perspective. Shot on a 100mm macro lens with an extremely shallow depth of field (f/1.8), causing the background to fall away into a soft, clean blur. The subject is a perfectly shaped mango resting on a dark, non-reflective, matte slate surface. The mango's body is made of flawless, crystal-clear glass that looks like a piece of perfectly clear, polished ice. It is completely transparent. Suspended perfectly in its center, a realistic, fibrous, brown and cream-colored mango seed is clearly visible. Delicate, gossamer-thin glass fibers, like ethereal threads, connect the seed to the inner walls of the glass fruit, catching and refracting the light beautifully. A gleaming, razor-sharp santoku knife made of polished stainless steel enters the frame. It moves with an impossibly slow and steady pace, beginning to slice into the top of the glass mango. The cut is clean and precise, not shattering the fruit but creating a perfect fissure. Professional studio lighting is paramount. A large, diffused softbox from the top-right provides the main key light, creating soft highlights and gentle gradients on the glass surface without harsh glare. A single, hard backlight acts as a rim light, aimed at the rear of the mango to brilliantly illuminate its edges and make the internal glass fibers and seed "pop" with light, emphasizing its perfect transparency. Audio is the primary focus. The soundscape is high-fidelity ASMR. The dominant sound is the crisp, sharp, crystalline fracturing of the glass as the knife cuts through it. This should be a clean, crunchy, satisfying sound with a slight, pleasant resonant ring, like ice cracking in slow motion. There are also subtle, gentle scraping sounds as the knife blade moves along the cut surface. The background is absolute, total silence (anechoic chamber ambiance). No music. No dialogue. Quality: Hyperrealistic, photorealistic, incredibly detailed, sharp focus, professional product photography, 8k resolution, immaculate, flawless. (no subtitles, no on-screen text). Negative prompt: blurry, noisy, dirty, scratches, messy, human hands visible, shattering, explosion, cartoon, ugly, distracting background, glare.
