Um faroleiro observa uma tempestade se aproximar, ondas escuras batendo nas pedras, grande plano cinematográfico, vento e trovões ao longe
Publicidade de luxo: um frasco de perfume de vidro esculpido gira devagar sobre uma pedra preta molhada, gotas d’água em um fino raio de luz dourada, névoa à deriva, lente macro, sem texto nem logo, som cinematográfico profundo
Animação 3D caprichada: um pequeno robô simpático monta com cuidado um cubo de vidro luminoso em um estúdio pastel limpo, iluminação global suave, órbita lenta de câmera, pequenos ruídos mecânicos alegres
Drone FPV rápido rente a uma praia com palmeiras na hora dourada, ondas quebrando, névoa quente, reflexo anamórfico, som do mar e do vento
