A 15-second multi-shot product commercial for the chunky clear lip gloss tube with crimson jelly gloss from reference image 1 (exact same faceted clear cap, ridged neck and deep crimson gloss, no label), served like a luxury dessert. SHOT 1 (0-3s): Overhead crane move descending onto a duck-egg blue table as a polished silver cloche lifts off a white plate, revealing the pink panna cotta with the gloss tube resting on it. The cloche's mirror surface reflects only the pale blue room and soft light — no people, no camera, no crew reflected anywhere. SHOT 2 (3-6s): Extreme macro side angle: the panna cotta wobbles gently, light rolling across its glossy surface and through the crimson gloss inside the clear tube. SHOT 3 (6-10s): Hard cut to a clean, empty, seamless pale duck-egg blue background — no plate, no dessert, nothing else in frame. The gloss tube floats upright in soft light and opens by itself: the faceted clear cap slowly unscrews and lifts away, drawing the applicator wand up out of the tube, a thick glossy string of crimson gloss stretching between the doe-foot tip and the tube neck and catching the light. Slow-motion macro, camera arcing smoothly around it. No hands, no people. SHOT 4 (10-12s): Same clean duck-egg blue background: macro on the glossy crimson doe-foot applicator tip, a single drop of gloss gathering and glistening, light refracting through the faceted cap. SHOT 5 (12-15s): Hard cut back to the table: low dolly gliding across and settling on the final hero frame exactly like reference image 1. SOUND: refined restaurant ambience, the metallic lift of the cloche, a soft wobble, the satisfying twist-and-pull sound of the cap opening, a glossy stretch, then a chic playful French-pop instrumental. LOOK: high-end cinematic beauty/tech commercial, editorial and refined, Jacquemus / Loewe campaign energy. Soft pale true-colour grounds against deep saturated hero colours, large soft diffused light, shadows soft but present, low-to-moderate contrast, creamy highlights, subtle 35mm film grain, shallow depth of field, anamorphic feel. CAMERA is always moving with bold confident motion — dollies, macro orbits, crane moves, motion blur on fast moves — never static. Product always tack-sharp and recognisable. Hard cuts between shots, each shot a different angle and scale, one clear story from start to end. Correct real-world physics. NO text, NO titles, NO captions, NO logos, NO subtitles anywhere. Audio: no voiceover, no dialogue, only a polished commercial soundtrack plus crisp tactile sound design.

Image 1 is the opening frame and the world of this video: the lanky teenage boy with curly copper-red hair and freckles, in an oversized faded navy-and-white vintage track jacket, grey shorts, red-striped white tube socks and scuffed white sneakers, in the sunlit art-deco station concourse with the checkered floor. Start exactly on Image 1. Every shot takes place in this station, in this light and this real photographic look. Image 2 is his character reference sheet: keep his face, hair, freckles, build and outfit exactly as in Image 2. Video 1 is the MOTION and CAMERA reference: perform Video 1's full-body choreography exactly, move for move, in the same order and with the same timing, and use the same three shots with the same cuts at the same moments. Take only the movement and camera from Video 1 — never its person, clothing, car park, skyline or sunset. Every shot is re-staged inside the station. [Shot 1, 00:00–00:04.7] Low camera at knee height, orbiting slowly around him, as in Image 1. He finishes the pivot on his left foot, steps his right leg far back into a deep low lunge, and holding the lunge sweeps his arms up until one arm reaches straight overhead. [Shot 2, at 00:04.7 cut to a medium shot from the front, closer, keeping his whole head and body in frame] He rises out of the lunge and turns with both arms spread wide, his loose jacket flaring out, then lifts one knee high to his chest with both arms raised overhead, balancing on one foot; then he drops down to the tiles and rolls sideways across the checkered floor in one continuous roll. [Shot 3, at 00:09.8 cut to a wide shot from behind him, low] He springs up from the floor and runs away from the camera across the long checkered floor toward the bright arched window, makes a small running leap, lands softly and stands still, chest rising, as the sun blazes through the window ahead of him. He belongs to the station in every shot: the sunlight from the arched window rims his curls and shoulders, and his shadow and faint reflection move with him across the polished tiles; his sneakers press into and push off the floor with real weight. PHOTOREALISM IS CRITICAL: real footage shot on 35mm film — a slight fine film grain, real skin with pores and freckles, real creased fabric, natural light; no gloss, never airbrushed, never CGI, never plastic. SPEED IS CRITICAL: everything moves at normal real-time speed, like 24fps footage played back at 24fps - natural motion, NO slow motion. Sound: sneakers squeaking and sliding on stone tiles, the nylon jacket swishing, the echo of the huge empty hall, the station clock ticking. Music: an upbeat, bouncy indie-pop track with handclaps that lifts at the final leap. Mix the sound effects and music clearly and fully audible.

"Level 1" — a short, clear story. References: Image 1 is the HERO, a real boy in a sky-blue knitted power-suit with pom-pom antennae — he is always this boy. Image 2 is his SIDEKICK, a felted green caterpillar — always this caterpillar. Image 3 is the BOSS, a giant crocheted crow with mismatched button eyes and a tiny crown. Image 4 is the knitted meadow level. Image 5 is the knitted boss arena with the yarn nest. Image 6 shows the collectible knitted heart, golden button and felt star. Image 7 shows the sewing-tin treasure chest. Keep every character, place and object exactly as in its reference. The world: a REAL handmade knitted video-game world filmed for real like a stop-motion feature — matte wool, felt, crochet and impasto paint, bright toy colours, soft daylight, slight film grain. Side-scrolling camera. No on-screen text, no numbers. [Shot 1, 00:00–00:06] The meadow of Image 4, camera tracking sideways: the hero runs right, bounces off a red felt toadstool springboard and hops across the floating wool-cushion platforms, snatching golden buttons from Image 6 out of the air — each one pops into a little puff of yarn fluff; the caterpillar sidekick wriggles along behind him. He grabs the knitted heart from Image 6 and it bursts into a shower of tiny felt hearts around him — the boy himself does not change at all. At the end of the meadow he and the caterpillar dive head-first into the open end of a giant striped knitted tube lying on the grass. [HARD CUT at 00:06] The boss arena of Image 5: the hero shoots out of the other end of the knitted tube, tumbles, and lands on his feet; the caterpillar plops out after him. [Shot 3, 00:07–00:12] The giant crow boss from Image 3 rises out of the yarn nest, spreads its felt wings and swoops down at the hero; the hero jumps high and bounces once on the crow's head with both boots; the crow wobbles, its tiny crown flies off, and it flops back into the nest, dizzy. [Shot 4, 00:12–00:15] The sewing-tin treasure chest from Image 7 pops open beside the flag, golden buttons spilling out; the hero and the caterpillar jump up and down cheering. NO MORPHING — CRITICAL: every character keeps exactly its own body, species, face, size, costume and colours from its reference in every frame. Nobody and nothing ever transforms, melts, dissolves, merges, shape-shifts or turns into another character, animal or object. Scene changes happen ONLY on a clean hard cut, never as a morph or a dissolve. SPEED IS CRITICAL: everything moves at normal real-time speed, like 24fps footage played back at 24fps - natural motion, NO slow motion. Sound: soft woolly boings, plinky button pops, a sparkly twinkle for the heart, a whoosh through the tube, flapping felt wings, a muffled crow squawk, a cheerful chest pop. Music: a bouncy chiptune melody played on real toy piano, ukulele and glockenspiel. Mix the sound effects and music clearly and fully audible.
