Sora提示词：A realistic documentary-sty

A realistic documentary-style video set during early morning physical training at a U.S. military base.

A U.S. soldier finishes a group morning run and slows to a stop on a quiet base road.

His breath is visible in the cold air as he bends slightly forward, hands on his knees, catching his breath.

After a brief pause, he looks up at the camera and says “Happy New Year,” in a calm, slightly tired voice.

The moment feels natural and unscripted, as if recorded right after the run.

Soft early morning light, muted colors, other soldiers jogging away in the background.

Handheld camera feel, natural lighting, no cinematic effects.

Vertical 9:16 frame, raw, authentic military training realism.
