Single-Take Action Beat Video Style

{{selected_text}}

Camera: one tracking shot following the subject; keep the subject centered; no second camera movement.
Action: exactly one physical beat completed within {{duration_seconds}} seconds — a sprint, a leap, a swing, a dodge — with a clear start pose and end pose; no combos, no multi-character melee.
Aspect ratio: {{aspect_ratio}}.
Lighting & mood: high-contrast dramatic light; motion blur allowed on fast limbs; dust or debris accents where fitting.
Physics: real gravity and momentum; fabric and hair react to motion naturally.
Consistency: the subject's face and outfit stay stable; background is continuous, nothing teleports.
Negative: extra limbs, warped hands, body distortion, flicker, frame jitter, scene cut, unintended slow motion, unreadable text, watermark, logo.
