Generate with the best text-to-video model: A lone man lies half-buried in the snow, his parka's fur-lined hood crusted with frost, eyelashes clumped with ice. His cracked lips tremble as faint breaths escape into the freezing blue haze. His face is ghostly pale beneath the fur trim, stubble rimmed with frostbite, his red flannel shirt barely visible under a weather-beaten leather jacket zipped halfway to his chin. The camera lingers close on his face, 50mm lens captures the shallow depth of field, his breath fogging the lens. The blizzard swirls, the sound of the wind muffled like a heartbeat under ice. Suddenly, the ground shakes beneath him. A low rumble, deep, predatory. He blinks, dazed, then jerks upright as the snow around him ripples. The camera switches to a low tracking shot at 24mms as he starts to run, boots crunching into the powder, snow exploding around his legs. Behind him, the surface fractures, then bursts open. The man' s breath quickens; the camera mirrors his panic with handheld instability, whipping with each desperate turn. Overhead drone angle: a small, dark figure sprinting across an infinite frozen plain as something large tunnels beneath, its path a storm of upheaved snow chasing him like a living avalanche. He stumbles, regains footing, glances backeyes wide,lips cracked,panicin every breath.
