White studio background. Hands unbox the 30m LED string, plug into a 220V Brazilian outlet (visible plug), lights instantly turn on. Controller cycles through all 8 modes in rapid succession—each mode shown for ~0.8 seconds. Final frame: full strand glowing warmly. Center screen displays rotating Portuguese labels: “Constante”, “Onda”, “Piscar”, “Fade”… Ends with product pack shot and CTA text: “30m • 8 Modos • Pronto pra usar! ?”. Clean, no distractions, ticking SFX implied, vertical 9:16.
