Kling 4.0 Reference to Video (Video to Video) API on fal

Input

Prompt

The red and cream vintage tin wind-up robot from @Image1 stands on a glossy black turntable in a sleek chrome and glass record shop at night. It wears the sand-beige headphones with copper hinges from @Image2 over its square head, bobs its head in stiff mechanical beats to the music and lifts one riveted arm to adjust the earcup, while a vinyl record spins beside it under warm spotlights. Keep the robot's exact paint, porthole eyes and riveted tin body, and the headphones' exact color and materials. Slow orbiting camera, crisp metallic reflections, shallow depth of field.
