Kling 3.0 Omni 最好用的地方，是同一个主体能在几个入口之间接力。下面先用一只纸船演示文生、参考生、视频改写三个入口：先文生出一个镜头，再用参考生换场景，用视频改写换季节；再加一条渔港图生和三条商品、角色一致性案例。下面 7 条都是在 HiAPI 上真实生成的，提示词原样给出，点「用这个提示词生成」会在模型页自动填好。新用户注册送 200 积分，720p 3 秒一条 $0.30 起。
1. 文生视频：雨夜水沟里的纸船
从零出镜头，写清主体、环境、镜头怎么动。
文生视频 · 720p · 3 秒 · 16:9 · 关声音 · $0.30
A paper boat drifts down a rain-soaked city gutter at dusk, neon signs reflecting and rippling on the water; the camera glides low beside it as raindrops splash around. Cinematic, shallow depth of field, smooth tracking motion.
低机位跟拍（the camera glides low beside it）是这条的关键：镜头贴着水面，霓虹倒影才会铺满画面。
2. 参考生视频：同一只纸船换到森林小溪
一张纸船首帧图当主体参考，第 1 条视频当运镜参考，场景整个换掉。

The same white paper boat from the reference drifts along a sunlit forest stream at golden hour, leaves floating beside it, camera tracks low alongside it with the same smooth motion as the reference video. Cinematic, shallow depth of field.
提示词里写明 "The same ... from the reference" 和 "the same smooth motion as the reference video"，用参考图引导主体、用参考视频引导运镜；这条里纸船的形状和低机位跟拍都保留了下来。
3. 视频改写：雨夜改雪夜
把第 1 条视频原样传进去，只写要变成什么。
视频改写 · 720p · 跟随原视频 3 秒 · $0.429
Transform the scene into a snowy winter night: the gutter becomes a frozen stream with drifting snowflakes, the paper boat becomes a small glowing paper lantern boat, keep the exact camera motion and water movement from the original video. Cinematic, cold blue tones.
最后一句 "keep the exact camera motion and water movement" 保住了原视频的运镜和水流，只换季节、光线和纸船的材质。
4. 图生视频：晨雾里的渔港
一张静态照片做首帧，提示词只写接下来发生什么。
图生视频 · 720p · 3 秒 · 首帧 · $0.30
Morning fog slowly lifts over the harbor as the fishing boats rock gently on the water; the low sun breaks through the haze and glints on the wet pier, camera slowly pushes in along the dock. Cinematic, calm, photorealistic.
图生视频不用重复描述画面里已有的东西，把篇幅留给"雾散开、船在晃、镜头往前推"这些动作。
5. 商品镜头：锁住一瓶精华
两张同一瓶精华的不同角度照片放进 image_urls，镜头推近时瓶身、黑色滴管和琥珀色玻璃都保持不变。
参考生视频 · 1080p · 5 秒 · 关声音 · $0.645
Cinematic skincare product reveal. The camera slowly dollies in on the amber glass serum bottle from the reference images, standing on a round white marble pedestal, soft diffused studio light from the upper left, faint volumetric haze behind it. A single droplet of golden serum slowly forms and hangs at the tip of the black dropper. Shallow depth of field, premium commercial look, gentle highlights sliding across the amber glass as the camera eases in.
6. 角色镜头：同一个吉祥物换场景
正面和斜侧面两张图，吉祥物站在咖啡馆里挥手、歪头，薄荷绿面罩、圆眼睛和肚子上的按钮都清楚可见。
参考生视频 · 1080p · 5 秒 · 关声音 · $0.645
The matte-white robot mascot from the reference images stands in a cozy sunlit cafe with a warm morning glow from a window behind it. It gives a cheerful little wave with one arm, tilts its head, and its antenna bobs gently. Smooth friendly motion, soft bokeh of wooden cafe shelves in the background, a slow gentle camera push-in, wholesome animated-film look.
7. 两个主体同框：吉祥物介绍精华
两个主体都要锁住时，用 elements 分别命名，提示词里写 @mascot 和 @serum：
"elements": [
{"name": "mascot", "description": "Small matte-white rounded robot mascot with soft mint-green accents ...", "element_input_urls": ["ref-mascot-01.jpg", "ref-mascot-02.jpg"]},
{"name": "serum", "description": "Amber glass skincare serum bottle with a black rubber-bulb glass dropper cap", "element_input_urls": ["serum-1.jpg", "serum-2.jpg"]}
]

A clean, playful product commercial. @mascot stands beside a round white marble pedestal and gestures with one arm toward @serum resting on top of it, presenting it to the viewer. @mascot glances at the bottle, then turns to look at the camera. Soft diffused studio light, pale mint seamless background, a slow gentle camera push-in, premium yet friendly brand-ad look.

提示词怎么写更稳？
- 身份交给参考图，动作交给提示词：主体长什么样靠图，提示词只写镜头、动作和环境。
- 镜头动词放前面：dolly-in、tracks low、pulls back，先写镜头再写细节。
- 改写只写差异：视频改写写"变成什么"和"保留什么"，不用重述原视频。
