Vũ điệu thép lúc nửa đêm trong nhà kho

Create one continuous 15-second video, aspect ratio 16:9, with grounded industrial realism and a quietly monumental mood. [00-05s] Track laterally at walking speed behind a waist-high safety barrier, using a natural 35mm lens feel. A crane slowly guides a suspended steel beam toward an open warehouse bay; riggers manage taglines from outside the load path. Cool floodlights reveal mill scale, bolted connections, and damp gravel. [05-10s] Continue the same smooth track past a foreground column, maintaining the 35mm perspective. The beam approaches its connection while a nearby welder works on an already secured assembly behind protective welding screens. Restrained orange sparks fall naturally and extinguish against a fire-resistant catch blanket. [10-15s] Ease forward toward the screened welding station, retaining realistic arc exposure and textured shadows. The welder wears a lowered welding helmet, flame-resistant clothing, leather gloves, and safety boots; riggers wear hard hats, high-visibility clothing, gloves, and boots. A fire watch stands nearby with an extinguisher. Sound design: steady generator hum, distant crane mechanisms, light steel resonance, and crisp intermittent welding crackle.
