Create a 15-second premium cinematic commercial for @product. The film should feel like a high-budget sportswear advertisement: premium product cinematography, basketball-heritage mood, modern streetwear energy. Ultra-realistic. Elegant pacing. Bold final hero. No fantasy effects, no exaggerated CGI, no distorted proportions. @product stays locked to the reference: same shape, colours, materials, finish, label and logo in every shot. One single product, never duplicated. Shot flow, 15 seconds: 0–2s — box arrival and lid lift. @product shoebox on a dark studio floor under a focused overhead spotlight. Slow overhead push-in. The lid opens, tissue rustles, light spills inward. 2–5s — reveal and material macros. @product is lifted from the box in a low-angle beauty shot. Then tight glides across the real materials: leather grain, overlays, laces, collar, perforated toe, midsole and outsole tread. Light travels across the surfaces. No extra marks invented. 5–8s — court heritage. @product worn on a polished indoor basketball court, warm hardwood, soft arena light. Low wide-angle, then a low tracking shot through a moody arena tunnel. Only the legs and the shoe — no face, no other people. Distant ball bounce, sneaker squeak, firm footsteps. 8–11s — impact and street. A planted step in high-speed slow motion: the sole compresses, fine dust reacts. Then @product on a clean city street at blue hour, low dolly, confident walk forward. Legs and shoe only. 11–15s — studio hero. @product floats on deep black; a controlled orbit shows the full silhouette. A red-and-white light sweep travels collar to toe. It settles on a reflective dark floor with soft red highlights. Slow low-angle push-in into the final hero pose. Fade to black. No end card, no typography. Sound: cardboard, tissue rustle, leather creak, rubber friction, court squeaks, distant basketball, controlled whooshes, warm bass, a clean sting at the end. Music minimal, stylish, building into the hero. No on-screen text, no titles, no subtitles, no watermark, no logos that are not already on @product. Duration: exactly 15 seconds. Aspect ratio: 9:16.
