Prompt

5-second ultra-cinematic mythic teaser, horizontal 16:9. A woman rides a white horse across a clear turquoise sea, with the waterline splitting the world into two dimensions—above and below.

The opening is a half-above, half-underwater tracking shot, calm and sacred in tone, with realistic splashes and natural sunlight filtering underwater. The camera slowly pushes in with a slight arc as the horse walks steadily forward; the woman, dressed in flowing ivory robes, sits upright with a distant, prophetic presence, wind moving her fabric and earrings.

Brief cut to a close shot: she seems to sense a calling ahead, her eyes lift slightly, and her breath pauses for a moment.

The camera then widens as the horse continues forward with stronger splashes; the light on the horizon gradually intensifies, as if an unseen gate is opening.

The final shot pushes into the glow, conveying a sense of divine return and fate awakening. Premium cinematic look, realistic water physics, natural horse motion, subtle mystical atmosphere, no extra characters, no text.
