The Bison Wall — Herd Crossing the Prairie

A 13-second thunderous prairie aerial, 16:9, 24fps. A bison herd moves across the prairie — a brown wall a mile wide, dust rising, the ground trembling — the drone flying parallel to its front. 0-4s: the prairie at 5 PM — and the wall arrives: the bison herd a mile wide, a moving brown cliff of muscle and horn. The drone flies parallel to the front as dust rises in a golden curtain; calves run hard to keep up, tucked against their mothers' flanks. 4-9s: the parallel tracking continues — bulls at the front lower their great heads, horns catching the low sun; the herd's dust catches the light and glows from within. The ground trembles; grass flattens in waves ahead of the wall. A young bull breaks formation, wheels with a bellow, and rejoins; dust devils spin up in the herd's wake. 9-13s: the pull-back — the drone rises to reveal the wall's full mile-wide scale, the dust plume stretching behind it across the prairie. The herd flows on, thunderous and primeval, into the low sun — unstoppable, ancient, vast. Craft: the bison herd a mile wide — bulls, cows, calves; the prairie grass; the golden dust curtain; the low sun. Camera: parallel tracking shot along the herd's front, then a rising pull-back to full scale. Lighting: low 5 PM sun on brown hides, the dust glowing gold. Mood: thunderous, primeval, vast. Style: warm 4K prairie documentary, prairie tones and dust glow, 24fps, 13 seconds, 16:9.
