一、先给AI提需求
写一份无人机快速穿越央视大楼的拍摄画面的MinimaxH3的提示词，要大气环绕视觉，一条15秒，镜头过多用拆分成为2条，所用图片如下：
二、AI返回工作思路以及描述词
央视大楼 无人机穿越 H3 提示词 v1
日期：2026-10-17
主体：CCTV 总部大楼（北京 CBD，两塔内倾、顶部悬挑连接、整体成环）
规格：两条 15 秒，各 362 帧 / 24fps / 16:9
用途：MiniMax H3 Ref2VA 单段生成，后期硬切或首末帧衔接
一、为什么拆成两条
一条 15 秒塞不下完整叙事。真正要讲的是两件事，而且方向相反：
- 第一件是进入：从地面冲到楼上，从外面进到里面，观众被带着穿过去
- 第二件是审视：穿出来之后退开，绕一圈看清这栋楼到底是个什么形状
前者的运动是加速、贴近、穿入；后者是减速、拉开、环绕。两种运动方向在同一个镜头里切换，H3 会在切换点把楼体拧变形。所以拆两条，各自只保留一种主导运动。
拆点选在穿过门洞后减速悬停那一刻。这个点是全片唯一自然的停顿，也是唯一可以硬切而不违和的地方，运动模糊正好掩盖接缝。
二、建筑的硬事实（提示词里必须写死的）
这栋楼是最容易被模型画歪的建筑之一，因为它不是常规塔楼，任何“大概齐”的先验都会出错。以下几条要在每条提示词里重复写：
1. 两栋塔楼向内倾斜，顶部由一段水平悬挑连接，整体是一条连续折带弯成的三维环
2. 两腿之间有一个巨大的矩形洞口，位置在离地一百六十米以上，天空直接穿过去
3. 立面是深蓝灰玻璃幕墙加银灰菱形斜交网格，网格在每一个面上连续、尺度一致
4. 底部是低矮裙房，裙房顶上是白色卫星天线阵列
5. 建筑脚下是高架快速路，车流密集
模型最容易犯的三个错：把洞填上、把两塔画成平行、把网格画成随机碎裂的玻璃。提示词里的 CONSTRAINTS 段专门堵这三个。
三、Clip 1 进入
文件：prompt_clip1_v1.txt
节拍（不写时间码，靠顺序词推进）：
段
内容
运动
1
贴高架路面冲刺，护栏和车道线在近景撕裂而过
低空、加速、向前
2
沿近侧塔楼外立面垂直爬升，网格高速下扫
向上、贴近
3
顶部轻微横滚，从巨型洞口正中穿过
向前、穿过
4
穿出后急减速，悬停在结构内侧，远处塔楼填满画面
减速、停
四段共用一条上升弧线，方向单调，不折返，这是 H3 能扛住的形态。
时间与光照选蓝调时刻。玻璃幕墙在蓝调下会把冷色天空和暖色室内灯混成细密纹理，斜交网格每一格反光都不同，这是这栋楼最好看的时候，也是最能出“大气”的时候。代价是与你给的照片（白天）色温不同，几何仍然一致。
四、Clip 2 环绕
文件：prompt_clip2_v1.txt
节拍：
段
内容
运动
1
贴着内侧悬挑面起手，网格填满全画幅
静止到启动
2
向外侧倾转，开始四分之三环绕
环绕、缓升
3
近塔、悬挑、远塔依次掠过，互相遮挡
环绕
4
拉远升高，整环独立于天际线之上
后退、拉起
关键设计是遮挡揭示：靠前后遮挡产生的视差让观众自己看懂这是三维的环，而不是靠物体自转。这比旋转更高级，也更稳。
末帧固定为居中全景，方便后期接品牌字或标题。
prompt_clip1_v1
An aerial drone shot, cinematic, photorealistic, one continuous take, no cuts.
LOCATION: the CCTV Headquarters in Beijing, the loop building. Two leaning towers, both about two hundred and thirty metres tall, tilt inward toward one another and are joined at the top by a massive horizontal cantilever, so the entire structure reads as one continuous folded ribbon bent into a giant three-dimensional loop, leaving a huge rectangular opening between the two legs high above the ground, with sky passing straight through it. The facade is a dark blue-grey glass curtain wall carried on a silver-grey diagonal diagrid: a regular diamond lattice of mullions, uniform in scale, continuous across every face, each cell reflecting a slightly different piece of the sky. Lower podium blocks hug the base, their flat roofs carrying a scattered cluster of white satellite dishes and antennas. An elevated expressway runs along the foot of the building, packed with traffic, with a green landscaped strip between them.
ENVIRONMENT: blue hour, the last warm band of sun still low on the horizon behind the towers, the sky above deepening to a saturated indigo, thin high cloud catching the residue of daylight. Interior floors are already lit, so hundreds of small warm windows glow through the glass and mix with the cold blue reflection of the sky, giving the facade a fine dense texture of warm and cold cells.
CAMERA: one continuous accelerating flight, the drone is never seen. It begins very low, a few metres above the expressway surface, racing forward parallel to the traffic, the guard rails and lane markings tearing past in the foreground, cars sliding under and beside the lens. Without slowing, the drone pitches up and climbs vertically along the outer face of the nearest leaning tower, the diagrid rushing downward across frame, the building expanding until its lattice fills everything. Near the top the drone rolls slightly and threads straight through the great opening between the two legs, sky filling the frame for a heartbeat, the two inner faces of the towers sliding past on the left and right like a canyon. It emerges on the far side and decelerates hard, the far tower filling the frame ahead, the edge of the cantilever cutting a hard diagonal across the sky, and the shot comes to rest hovering just outside the inner face of the structure, looking along it.
LIGHTING AND ATMOSPHERE: low warm rim light grazing the outer corners of the cantilever, cold blue ambient filling the shadowed inner faces, the diagrid drawing a mesh of fine specular highlights that slide across the surface as the angle changes. A faint haze sits between the towers and the distant skyline, with aircraft warning lights blinking red at the roof corners. Slight natural drone drift, never mechanically frozen, no lens flare artefacts, no rolling shutter skew.
CONSTRAINTS: the structure never deforms, the two towers keep their exact inward lean, the cantilever stays horizontal and rectangular, the diagrid stays a regular continuous diamond lattice at constant scale, the great opening stays empty with sky visible through it at all times. One single building, never duplicated. No people, no text, no logos, no watermarks, no broadcast branding, no subtitles, no on-screen graphics. No cuts, no dissolve, no speed ramp, no added objects, no birds, no aircraft.

An aerial drone shot, cinematic, photorealistic, one continuous take, no cuts.
LOCATION: the CCTV Headquarters in Beijing, the loop building, seen from the far side after the camera has already passed through its great opening. Two leaning towers, both about two hundred and thirty metres tall, tilt inward and are joined at the top by a massive horizontal cantilever, so the whole structure reads as one continuous folded ribbon bent into a three-dimensional loop, with a huge rectangular opening between the two legs high above the ground, sky passing straight through it. The facade is a dark blue-grey glass curtain wall on a silver-grey diagonal diagrid: a regular diamond lattice of mullions, uniform in scale, continuous across every face. Lower podium blocks at the base, flat roofs carrying white satellite dishes. Elevated expressway with traffic below, landscaped strip, surrounding towers falling away into haze.
ENVIRONMENT: blue hour deepening toward night, the horizon still holding a thin band of warm amber, the zenith a deep indigo, the city below switching on: street lights strung along the expressway, windows in the surrounding towers lighting up in scattered grids, the low cloud overhead still faintly lit from beneath.
CAMERA: one continuous grand orbit, the drone is never seen. It starts close to the inner face of the cantilever, so close that the diagrid fills the entire frame and the edge of the structure cuts a hard diagonal across the sky. It then banks outward and begins a wide, smooth three-quarter orbit around the whole loop, climbing gently, keeping the building locked near the centre of frame while the background city slides the other way. The orbit opens up gradually: the near tower, then the cantilever, then the far tower swing past in sequence, each occluding the others, so the true three-dimensional form reveals itself through parallax rather than through rotation. In the final seconds the drone pulls back and up into a wide establishing frame, the entire loop standing alone against the glowing horizon and the darkening skyline, its inner faces filled with warm windows and its silhouette crisp.
LIGHTING AND ATMOSPHERE: warm rim light on the outer edges, cold blue ambient inside the loop, the diagrid drawing continuous chains of specular highlights that crawl along the surface as the orbit proceeds, warm window grids glowing from within, thin haze layering the city behind in three depths, red aircraft warning lights at the roof corners, slight natural drone drift, no lens flare artefacts, no rolling shutter skew.
CONSTRAINTS: the structure never deforms, the two towers keep their exact inward lean, the cantilever stays horizontal and rectangular, the diagrid stays a regular continuous diamond lattice at constant scale, the great opening stays empty with sky visible through it at all times. One single building, never duplicated. No people, no text, no logos, no watermarks, no broadcast branding, no on-screen graphics. No cuts, no dissolve, no speed ramp, no added objects, no birds, no aircraft.
END FRAME: a wide symmetric establishing view of the entire loop building centred in frame, sky above, skyline below, nothing else in the foreground.
