Kling VIDEO 3.0 4K
Kling VIDEO 3.0 4K is the 4K variant of Kling VIDEO 3.0 for text-to-video and image-to-video generation. It extends the 3.0 series from 720p Standard and 1080p Pro into 4K output while keeping the same multimodal strengths: native audio generation, multi-shot sequencing, element consistency, prompt-driven scene control, and stable temporal coherence across longer clips.

"prompt": "Ultra-detailed wide establishing shot of a vast white salt plain cracked into geometric plates, bordered by smoking black volcanic ridges. Three towering pack animals with woven copper saddles carry glass spheres filled with fluttering paper maps. Dawn haze, long shadows, mirage shimmer, slow dolly forward, epic cinematic realism, rich texture, grand scale.",

{
"prompt": "Medium tracking shot alongside the caravan as warm wind skims the salt crust and tiny spirals of mineral dust curl around their feet. The lead traveler wears layered indigo fabric and a mirror-mask that reflects the glowing lava seams in the distant hills. One glass sphere catches sunlight and throws moving prismatic flecks across the animals and ground. Natural motion, stable subject continuity, detailed materials, immersive cinematic atmosphere.",

{
"prompt": "Low-angle closing shot as the caravan reaches a field of towering basalt columns rising from the flats like an ancient gateway. Heat shimmer bends the horizon, embers drift from fissures far away, and the reflected sky in the glass spheres turns from pale gold to fierce orange. The camera cranes upward to reveal the full landscape, majestic ending, high-end film look, realistic environmental audio cues and cohesive visual continuity.",

"positivePrompt": "A majestic frozen library built into a vast glacier canyon comes alive. The camera begins wide and slowly glides forward along a narrow bridge toward a lone archivist in a crimson fur-lined coat, then subtly rises to reveal immense shelves trapped within clear ice walls and drifting paper scraps circling in cold air. Frost crystals shimmer, old banners stir gently, tiny avalanches of powder fall from ledges, and a soft polar sky glow washes the canyon in pale green and violet highlights. Cinematic fantasy realism, grand scale, precise textures in ice and carved stone, strong depth, stable temporal coherence, elegant environmental motion, immersive atmosphere, natural ambient sound of creaking ice, distant echoes, fluttering pages, faint footsteps on frosted wood",

Maintain the same architecture and central violinist throughout the clip for strong temporal consistency. Slow gliding camera movement at human eye level across reflective water, subtle ripples, drifting dust motes, hanging fabric gently stirring, distant birds entering as greenery thickens, shafts of sunlight intensifying over time, fish occasionally disturbing reflections, elegant realistic motion, highly detailed materials, grand scale, emotionally uplifting, natural environmental soundscape with echoing water, soft footsteps on wet stone, faint violin notes blending into ambient life.",

"positivePrompt": "A colossal weathered pilgrimage mech walks slowly through a vast amber stone quarry at golden afternoon, carved terraces rising on all sides. Its body is built from brushed brass, ceramic plates, canvas prayer ribbons, and soot-dark joints, carrying small lanterns that sway from its shoulders. Tiny human attendants in pale dust cloaks move alongside its feet for scale. The camera begins with a low wide cinematic view of fractured quarry ground, then gently cranes upward and drifts closer as the mech steps over broken slabs, sending pebbles sliding and ochre dust into the air. Sunbeams catch suspended grit, distant quarry lifts and suspended cables hang across the background, and flocks of white birds burst from cliff ledges as the machine passes. Emphasize realistic weight, articulated leg mechanics, subtle cloth movement, rich mineral textures, volumetric light, stable temporal coherence, epic realism, highly detailed 4K cinematic imagery. Natural synchronized audio: heavy metallic footfalls, creaking joints, stone crunch, fluttering fabric, birds calling, quarry echoes, low resonant mechanical hum.",
