        "prompt": "Luxury lip gloss commercial with smooth premium camera moves. The brushed-silver each::labs lip gloss tube lies on a glossy black mirror surface in darkness as a thin line of warm light slides along it. The tube rises upright, its cap lifts off into the air and a glossy ribbon of warm brown gloss spirals up around it in slow motion. The camera glides into a macro of the applicator tip as a thick drop of gloss stretches, falls and splashes into a liquid crown in a pool of brown gloss. The gloss settles into smooth concentric ripples and the tube, cap closed, stands centred in the pool for the final hero packshot. The tube and its each::labs lettering stay identical throughout. Warm golden light, rich glossy textures, slow-motion liquid. Sound: a deep whoosh, silky liquid pours and drips, and a soft bass hit on the final packshot.",
