简单探索了一下全 AI 生成视频，包括文生图、图生视频、文生视频、音频生产、音乐生成。下面是视频浏览和技术实现方案。

轨道电梯这个概念来自《机动战士高达00》，借助动画中的设定生成的此视频。动画片中轨道电梯的设定大概是：

轨道电梯是一座巨大的建筑物，全长五万公里。以地球的一万两千七百公里的直径作为参照物，它的巨大可见一斑，差不多为地球直径的四倍左右。从距离地球较为遥远的宇宙空间遥望，轨道电梯就像是将被称作地球的蓝色的团子穿起来的细长的金属针，三根针同时将地球穿在中间，像要防止地球逃跑一样。但轨道电梯也由于体积巨大难以防卫。从构造上来看也是十分脆弱的建筑物。因此国家组织体在其所有的轨道上都配备了军力，三条轨道在一万公里和三万六千里的高处分别设置了轨道环来加固连接。
轨道电梯的两个主要作用：其一是做地球和宇宙之间的物资传送。通过架设在轨道电梯内部的垂直运输通道在地球和宇宙空间之间往来，这在造价上的便宜和安全性都得以实现。另一职能则是通过太阳能发电系统提供能源。轨道电梯通过粗大的传导缆绳，将大量分布在宇宙空间之中的发电卫星所产生的巨大电力传输到地球表面。作为过去垄断全球的化石燃料的替代品，从其顺利地发挥着解决能源缺失问题的作用看来，就可以得知其所提供的电量是如何巨大。

图像生成

首先，用关键词简单生成几张图片作为参考，选择合适的图片作为视频的风格给后面的视频生成作为参考。这里使用 FLUX 模型简单生成了几张图片，提示词参考：

A realistic futuristic space elevator rising into the sky from Earth's 
surface, a busy station with people boarding the elevator, glowing cables 
stretching into the clouds, high-tech structures, sunrise lighting, ultra-
realistic style, 4K

大概效果如下：

视频生成

分别使用 通义万相2.2-图生视频-A14B 和 可灵 1.6 进行视频的生成。

提示词主要有：

Three futuristic space elevators connecting Earth to space, visible from orbit, realistic, Earth viewed from space

Futuristic orbital elevator interior, magnetic levitation train, zero gravity environment, sci-fi

Sci-fi space station connected to orbital elevator, glowing solar arrays, sic-fi, realistic

Inside a futuristic space elevator cabin, people looking out of glass windows, realistic view of Earth below, moving past clouds and atmosphere, sunlight reflecting on the elevator structure, ultra-realistic cinematic style, slow movement, 4K

Arrival at a giant space station orbiting Earth, space elevator docking slowly, massive rotating structure, people stepping out into microgravity, panoramic view of Earth from orbit, extremely detailed, photorealistic sci-fi setting, 4K

Earth with three orbital elevators extending into space, sunrise, hope, futuristic, cinematic tone

A massive futuristic space elevator station on Earth, people preparing to board, the elevator structure stretching into the sky and disappearing into the clouds, glowing cables, sleek high-tech design, sun rising in the background, ultra-realistic and cinematic, 4K

Distant wide-angle view of a space elevator connecting Earth to a space station in orbit, the Earth glowing in blue and white, stars filling the black space around, the structure glows softly, ultra-photorealistic, majestic cinematic ending shot, 4K

A massive futuristic space elevator station on Earth, people preparing to board, the elevator structure stretching into the sky and disappearing into the clouds, glowing cables, sleek high-tech design, sun rising in the background, ultra-realistic and cinematic, 4K

A hyper-realistic wide shot of a massive space elevator stretching from Earth's surface into space, visible from orbit. The Earth is glowing with sunlight on one side, stars and the blackness of space behind. The space elevator appears as a vertical megastructure, disappearing into the distance. No explosions or military elements. Photorealistic, cinematic lighting, 8K detail, high contrast, dramatic scale.

A photorealistic cinematic wide shot of a perfectly vertical space elevator rising straight from Earth's surface into outer space, captured from a fast upward-moving camera. The elevator is a sleek, futuristic megastructure extending through the clouds into the stratosphere and beyond, with Earth’s curvature visible below. The sense of extreme height and rapid vertical movement is conveyed by the changing scenery—cloud layers rushing downward, atmospheric layers shifting, and stars becoming visible. No motion blur. Highly detailed, realistic lighting, 8K quality, epic science fiction style.

音频生成

利用模型 CosyVoice2-0.5B 实现，使用的是 3s 极速复刻，喂了一段上译的奥特曼配音解说片段进去，自动生成 prompt 文本，手动修改一下 prompt 文本内容，然后直接用文字生成音频。

音乐生成

利用 ACE-Step 模型，Prompt：

Tags：

orchestral, cinematic, melodic, rich harmony, slow build, climax,
progressive, ambient, synthesizer, piano, cello, emotional, variation,
dynamic, futuristic, textured

Lyrics：

[instrumental]

最后视频手动使用 PR 剪辑，ArcTime 上字母。
