Parfum sous la lumière d’un prisme

Create a 20-second photorealistic product film in a controlled tabletop studio, horizontal 16:9. The only product is an unbranded rectangular clear-glass perfume bottle containing amber liquid, with a short brushed-silver cap and a narrow cream label without writing. Place it upright on a matte charcoal plinth. A glass prism stands beside it, never touching it. Soft white key light remains constant; one off-camera lamp slowly sweeps through the prism to move a restrained rainbow across the background. 0–5s: begin with the complete bottle in a medium close-up, camera sliding gently right; show its contact shadow and stable liquid level. 5–10s: hard cut to a macro view of the shoulder and cap. Rack focus once from the brushed metal to the glass edge while the colored reflection passes behind, never changing the bottle's material. 10–15s: hard cut to a low three-quarter view; a slow quarter-orbit reveals the prism beside the bottle, with reflections following the new angle. 15–20s: hard cut to the original frontal composition; the lamp stops, the camera eases to rest, and the bottle holds for two seconds. Preserve the same bottle proportions, cap, label placement and liquid level across every cut. Glass refracts the plinth naturally; neither object floats or morphs. Sound: quiet studio air and a subtle original sustained tone that fades at the hold. No speech, captions, logos or watermarks.
