Đổ bê tông sân trong dưới ánh hoàng hôn

Create one continuous 12-second video, aspect ratio 9:16, in a sheltered residential courtyard under construction. Use a warm, calm, tactile mood and physically believable concrete movement. Workers wear hard hats, safety glasses, hearing protection, gloves, high-visibility vests, and concrete-resistant safety boots.
[00-04s] Begin with a slow descending jib move, 85mm close-focus lens feel, beside a chute releasing concrete into a shallow formed strip. A worker carefully directs the flow; heavy folds settle around visible aggregate. Low golden sunlight creates detailed highlights without making the mix look metallic.
[04-08s] Continue the same move in a gentle arc around a timber form corner, revealing a separate courtyard section placed earlier and now ready for troweling. A worker guides a compact walk-behind power trowel into view. Warm rim light outlines the guard ring and dusty boots.
[08-12s] Settle into a close lateral drift beside the guarded machine as it advances evenly, leaving subtle overlapping finish patterns on the firm slab. Keep the camera safely clear of equipment and preserve natural surface variation.
Sound design: soft chute rumble, dense wet pattering, a restrained engine buzz, and faint evening breeze.
