Dạo một vòng công trường buổi sáng

Create one continuous 12-second vertical social video, aspect ratio 9:16, filmed in an authentic UGC style by a construction worker holding a phone at arm’s length. The setting is a mid-rise building site during early morning, with timber framing, stacked materials, and clean, organized access paths. The worker wears a white hard hat, high-visibility vest, safety glasses, gloves, work trousers, and protective boots. [00-04s] Handheld front-facing camera moves with natural walking sway, wide phone-lens feel; the worker greets the camera silently with a relaxed expression and turns slightly to reveal the active site behind him. Cool dawn light creates soft shadows, with warm sunlight beginning to touch the upper structure. [04-08s] The camera rotates outward toward a nearby crew member safely measuring a wall frame, then pans across neatly stored materials. [08-12s] The camera returns to the worker as he gives a confident thumbs-up and continues walking toward the building entrance. Maintain realistic footsteps, subtle autofocus shifts, natural exposure changes, believable scale, and no visible text, logos, or watermarks. Sound design: footsteps on compacted gravel, distant tools, light morning wind, and natural phone-microphone handling noise.
