Smart Device Assembly Demo

Create a 10-second vertical 9:16 ultra-realistic product demonstration video showing a person assembling and installing a compact white smart electrical device.

Start with a close-up of a small retail package placed on a miniature wooden table. Two realistic human hands carefully remove the white device from its packaging. Transition into macro close-ups as the hands open the device, expose its internal mechanism, and use a tiny screwdriver to adjust/install the components.

Then show the person holding the completed white device and positioning it against a wall-mounted electrical switch/socket. Finish with a close-up of a finger pressing the switch button, making the device appear fully installed and functional.

Style: photorealistic, satisfying DIY/product-assembly aesthetic, miniature-scale feel, warm indoor lighting, shallow depth of field, realistic skin texture, detailed plastic surfaces, smooth hand movements, macro cinematography, subtle sparkle effects, cinematic focus pulls, clean composition.

Camera: vertical smartphone-style macro shots, slow controlled camera movement, close-up framing, realistic depth of field, smooth transitions, 4K detail.

Important: preserve realistic hand anatomy, natural finger movement, accurate object proportions, realistic mechanical interactions, no distorted fingers, no extra objects, no text glitches, no sudden camera movements.
