Khung thép dưới bầu trời sao trên núi

Create one continuous 15-second video, aspect ratio 2.39:1, at a remote hillside construction site beneath a clear night sky. The mood is quiet, resilient, and expansive. [00-05s] Start a slow ground-level arc along a designated camera lane outside the exclusion zone, using a spacious 24mm lens feel. A low-rise steel skeleton stands against dark hills. Portable floodlights rake dusty concrete pads and matte steel, while a crane holds a roof beam steady near its intended connection. [05-10s] Continue the gentle arc without cuts or speed changes. Riggers wearing hard hats, high-visibility clothing, gloves, and safety boots manage taglines from clear ground positions. In a separate completed bay, a welder works behind protective screens; occasional sparks drop into a fire-resistant catch area, never showering other workers. [10-15s] Ease to a stop with diagonal bracing framing the protected welding station and distant hills. The welder wears a lowered helmet and full flame-resistant PPE; a fire watch remains attentive nearby. Keep stars subtle under the work lights, crane motion measured, and all steel rigid with believable weight. Sound design: open-air wind, faint insects, steady generator rumble, gentle rigging tension, and short welding crackles.
