Regenerate a horizontal concept as a true vertical clip instead of a cropped one
A Kling 3.0 brief for turning an existing widescreen scene idea into a genuinely re-blocked 9:16 clip — repositioning the action for a tall frame rather than just cropping the sides off a horizontal shot.
The prompt
Ready to copy — highlighted parts are example details you can swap.
Original concept: a wide two-shot of two coworkers walking and talking across an office floor was shot or conceived for a wide 16:9 frame. This version re-blocks it for a 9:16 vertical frame. Subject and action: one coworker, walking toward camera, the other trailing slightly behind, repositioned so the main action sits in the vertical center third of frame rather than spread horizontally — do not simply imagine a wide shot and crop the sides. Camera: a single vertical-friendly move (slow tilt or straight push-in) instead of the horizontal pan or wide two-shot the original concept implied. Focal point: keep the lead coworker's face and the object they're holding as the one element the eye should land on throughout, since a tall frame can't hold two separated points of interest the way a wide frame could. Environment and lighting: a narrow office hallway with soft overhead lighting, background simplified or blurred so it doesn't compete for space in the narrow frame. Style and mood: same tone as the original concept, but staged for a viewer holding a phone vertically, not watching a shrunken widescreen video. Audio: dialogue or key sound centered and dry, no elements that rely on wide stereo separation.

Why this works
The most common failure in vertical repurposing is treating 9:16 as a crop of a 16:9 idea, which either clips the subject out of frame or leaves a tall, empty, awkwardly-blocked composition — this prompt heads that off by explicitly instructing Kling 3.0 to re-block the action around a single vertical focal point rather than imagining the wide version first and cutting it down. Collapsing a two-shot into a lead-and-trailing-subject composition is a deliberate concession to how much visual information a 9:16 frame can hold at once: a wide frame can give two people equal weight side by side, but a tall frame forces a hierarchy, and naming that hierarchy up front (one focal point, one secondary element trailing) is what keeps the re-generated clip from looking like a wide shot the model was straining to fit into portrait bounds. Simplifying the background and centering audio without relying on stereo separation both address the same underlying constraint — a vertical, typically phone-viewed clip has less peripheral frame and is usually heard through a single phone speaker, so visual and audio choices that depended on width or stereo width in the original concept need to be substituted with center-weighted equivalents.
What you get back
A vertical 9:16 clip: one coworker walks toward camera down a narrow, softly lit hallway holding a folder, a second coworker trailing a half-step behind and slightly out of focus, the background simplified to a plain wall, dialogue centered and clear.
