12 seconds, 16:9. PRODUCT: a hand coffee grinder, walnut brown with brushed stainless steel, oiled open-grain walnut on the cylindrical body and matte brushed steel on the upper collar, the crank arm and the base ring; a slim cylindrical walnut body about the height of a tall glass, a brushed steel collar seated on top of it with a visible flush seam where metal meets wood, a single brushed steel crank arm rising from the centre of the collar and bending once at a right angle to a small rounded walnut knob, and a knurled brushed steel adjustment ring encircling the very bottom of the body with fine vertical grooves cut into it; accessories: a clear glass storage jar with a brushed steel screw lid, a small brushed steel scoop, a short brush with a pale wooden handle. The product stays identical in shape, colour, proportions, wood grain direction, steel finish and the geometry of the crank arm and the knurled ring throughout. There is no printed text, no logo, no engraving and no marking anywhere on the product or on any accessory. SCENE: the product centered on a light grey studio surface against a light grey backdrop; even studio softbox lighting from above and slightly front, soft true reflections of the walnut and the steel in the surface, no props, no shadows on the backdrop. Background, surface and light do not change. 0-3s REVEAL - a plain light grey box lid lifts straight up and out of the top of frame, showing the grinder standing upright and centered, crank arm attached and still. Static front view, camera locked. HARD CUT. 3-6s DETAIL - macro on the bottom of the body: the knurled steel adjustment ring fills the lower frame with the flush seam between the brushed steel collar and the oiled walnut visible above it. The camera pushes in slowly and straight; a soft highlight slides along the grooves of the knurled ring and across the open grain of the wood. The product does not move. HARD CUT. 6-10s ORBIT - one single continuous camera move with no cut anywhere inside this segment. The camera travels around the standing grinder anticlockwise at constant height and constant speed, keeping the grinder centered in frame the whole way, and what the frame shows changes as it goes: at about 7s the camera is level with the right side of the body, the crank arm running away from the lens in sharp foreshortening and the knurled ring seen edge-on; at about 8s the camera is directly behind the grinder, the crank arm pointing away from the lens so that only the smooth back of the brushed steel collar and the walnut knob beyond it are visible, and the wood grain reads as an unbroken cylinder with no seam facing the lens; at about 9s the camera is level with the left side, the crank arm now sweeping toward the lens from the far side; by 10s the camera has returned to the exact front view of the opening shot. The grinder itself does not move, does not rotate on its axis and does not tip at any point - every change in the picture comes from the camera having travelled. The crank arm keeps its exact length, thickness and right-angle bend at every one of these positions, and the walnut grain runs vertically on the body throughout. HARD CUT. 10-12s ACCESSORIES - the three accessories lie neatly in a row on the grey surface beside the standing grinder, evenly spaced and not touching: the glass jar, the steel scoop, the wooden-handled brush. A slow macro pan travels left to right across them. Hold the final frame perfectly still for the last half second. SOUND: none. AVOID: any text, lettering, character, digit, logo, engraving, brand mark or watermark anywhere in frame, on the product, on the accessories, on the surface or on the backdrop; subtitles, captions, logo overlays, interface graphics. No deformation of the crank arm, no bending, kinking, thinning, thickening, doubling or disappearing of it, and no parts clipping through each other. No second grinder, no duplicated accessory, no extra jar, scoop or brush, and no accessory appearing before the final segment. No hand, no arm, no finger, no person and no reflection of a person in the steel or the glass. Nothing floats; every object stays in contact with the surface. No camera shake, no handheld motion, no zoom, no rack focus, no sudden reframing, no dissolves, no fades between shots, no speed ramp. The grinder never tips, rotates on its own axis, opens or comes apart, and the wood grain never changes direction. No plastic or CGI look, no oversaturated grade, no lens flare stars, no sparkle particles, no floating dust motes. hyper-realistic textures, realistic reflections of walnut and brushed steel, smooth 60fps motion.
