科幻与太空 AI 视频提示词：12 条从轨道到深空的即抄即用场景

太空是 AI 视频的天然主场。观众没有日常物理参照物可以对照——没人真在空间站舷窗外看过地球，没人知道失重布料”应该”怎么飘——于是 AI 最容易穿帮的地方全部消失，而回报反而拉满：宏大尺度的奇观感，正是推荐流量最吃的画面。下面是 12 条可直接复制的科幻太空提示词，适用于 Veo 3.1 / Kling 4.0 / Seedance 2.5 / Hailuo 3 / Wan 3.0 等模型，写法上带足了让真空像真空的质感词汇。

为什么太空场景特别适合 AI 生成

• 没有参照物，就没有穿帮。街景会暴露 AI 的手和招牌，轨道不会——观众没有”正确答案”可比对。
• 尺度即流量。行星弧线、星云高墙、星球都市远景，随手一帧就是让人截图转发的”哇”帧。
• 光在替你干活。硬日光、深阴影、镜头光晕、大气辉光——单一光源自带无限戏剧性。
• 每条镜头都有现成运动。轨道漂移、工具漂浮、低重力尘埃，动效提示词自己会写。

太空提示词公式

[Shot type] of [subject + material/texture], [action beats with zero-G physics],
[environment + time], [camera move], [lighting: hard sun / earthshine / lens flare],
[style/color grade], [mood], [audio: comms static, low hum, silence].

三条让太空像太空的规则：

1. 先写光源。太空里只有一个太阳，其余都是反射：harsh unfiltered sunlight（无大气过滤的硬日光）、earthshine fill light（地球反照补光）、lens flare from a distant sun。光源不写清，太空就像室内。
2. 失重要明写。zero-G cloth movement（失重布料运动）、tools drifting on tethers（工具系绳漂移）、hair floating inside the helmet ring。重力是最先被伪造、也是观众最先感觉到的东西。
3. 保住暗部。深空就是黑：deep shadow with no fill、pure black starfield、high contrast rim lighting。死黑 + 一个亮源 = 立刻有电影感。

1. 晨昏线日出

Wide shot from inside a space station cupola window: Earth's curved horizon fills
the lower frame, the terminator line sliding across continents, city lights on the
night side, a thin blue atmosphere limb igniting orange as the sun crests with a
hard anamorphic lens flare, slow orbital drift, faint interior reflections on the
glass, awe-struck silence mood, low cabin hum and comms crackle audio.

全篇最”出片”的一条。Earth's terminator line（晨昏线）+ atmosphere limb（大气边缘辉光）是轨道感的灵魂词，太阳务必带 lens flare。

2. 轨道飞掠

Slow flyby of a modular space station in low Earth orbit, gold foil insulation and
blue solar arrays catching unfiltered sunlight, a resupply capsule drifting toward
the docking port with tiny thruster puffs, Earth's clouds rotating far below,
smooth lateral tracking shot, silver and gold against deep black, lonely majestic
mood, muffled thruster rumble audio.

gold foil insulation（金箔隔热层）这类材质词让空间站不像塑料玩具，微型推进器喷雾给画面以物理感。

星云与深空奇观（2 条）

3. 穿越星云

Slow forward flight through the heart of a vast emission nebula: volumetric nebula
clouds in teal and magenta billowing like smoke, newborn stars igniting inside gas
pillars, dust lanes silhouetted against glowing hydrogen, a distant sun flaring at
the frame edge, IMAX-scale deep space photography, saturated colors against pure
black, transcendent mood, deep sub-bass drone and ethereal shimmer audio.

volumetric nebula clouds（体积星云）是这类镜头的核心词，dust lanes（尘埃带）给云气加出层次。

4. 黑洞

Wide shot of a supermassive black hole with a glowing orange accretion disk, its
light bent over and under the shadow by gravitational lensing, a thin photon ring
at the horizon edge, camera slowly pushing toward the shadow, extreme contrast
between incandescent disk and absolute black, Interstellar-style scientific awe,
deep rumbling bass and warped silence audio.

黑洞靠 gravitational lensing（引力透镜）和 photon ring（光子环）两个词立住，配上低频轰鸣音效更完整。

宇航员舱外行走（2 条）

5. 无系绳 EVA

Medium shot of an astronaut on an untethered spacewalk above Earth's blue ocean,
white EVA suit with a scuffed gold visor, helmet visor reflections of station and
curved Earth, safety tether drifting in slow lazy coils, suit fabric creasing with
zero-G cloth movement, hard sunlight from frame left with deep black shadow side,
slow rotating camera, tense quiet mood, amplified breathing and comms static audio.

helmet visor reflections（头盔面罩反射）是宇航员场景的质感天花板——反射里必须有地球或空间站。

6. 桁架维修

Close-up on a gloved hand gripping a handrail on an exposed station truss, a
wrench drifting away in slow motion on a lanyard, tiny ice crystals sparkling in
the airlock vent, Earth's terminator line far below, harsh raking sunlight with
stark truss shadows, slow push-in, workmanlike mood, muffled suit servo whir and
rhythmic breathing audio.

特写 + 漂浮工具是失重感最稳的写法；ice crystals sparkling 给真空环境加”呼吸感”。

7. 踏上外星

Wide low-angle shot: an astronaut in a white exploration suit descends the ladder
of a scorched lander onto rust-red alien regolith, boots kicking up dust plumes
that fall in slow low-gravity arcs, twin suns low on the horizon casting double
shadows, pale lavender sky with thin atmospheric haze, slow push-in, desaturated
rust and bone-white palette, historic lonely mood, thin-atmosphere rumble and soft
boot crunches audio.

双重影（double shadows）+ 低重力尘埃弧线，一条词就和”地球沙漠”拉开差距。

8. 水晶峡谷行进

Tracking shot following a lone astronaut through a canyon of towering translucent
crystal formations on an alien planet, crystals refracting the low sun into
spectral glints, fine dark sand underfoot, a distant ridge dissolving into
atmospheric haze, rover tracks winding behind the figure, slow lateral track at
walking height, cool violet grade with warm sun accents, awed mood, crystalline
chimes and soft wind audio.

translucent crystal formations + refracting the low sun 让外星地貌有光学层次，避免”红色地球沙漠”的既视感。

飞船内部与舷窗（2 条）

9. 驾驶舱跃迁

Over-the-shoulder shot inside a starfighter cockpit: worn analog switches and warm
amber instrument glow, a pilot silhouette in a scuffed flight helmet, the canopy
framing a starfield that stretches into blue-white light streaks as the ship jumps
to faster-than-light travel, camera pushing past the pilot's shoulder, amber glow
against blue-white streaks, adrenaline mood, spooling drive whine and boom audio.

跃迁瞬间 = 星点拉成光条。spooling drive whine（引擎充能声）让跃迁”响”起来。

10. 星际客机舷窗

Medium shot inside a quiet starliner cabin: a traveler in a soft grey knit sweater
floats gently against a large oval porthole, a ringed planet filling the window
with soft banded light, a tea droplet drifting weightlessly from a pouch, warm
reading lights against cold planet glow, slow drifting camera, cozy reflective
mood, low engine hum and soft cabin chime audio.

太空片也需要”安静”。失重茶滴这类小物理，比宏大奇观更容易让观众停留。

赛博朋克都市远景（2 条）

11. 巨城飞越

Aerial wide shot gliding over a rain-soaked megacity at night from above the cloud
break, thousands of tower windows glowing, holographic advertisements projected
between skyscrapers, streams of flying vehicle lights threading the canyons, a
maglev train streaking across the frame, slow forward flight, cyan and magenta on
wet black architecture, electric dystopian mood, distant traffic roar and sub-bass
city hum audio.

这组主打科幻尺度而非巷弄霓虹：above the cloud break + 车流光轨，把城市拍成”星系”。

12. 黄昏巨构天际线

Slow aerial ascent along a colossal arcology tower at dusk, layered balconies and
sky-bridges with tiny glowing signage, drones swarming like insects between
buildings, last sunlight flaring along the tower's edge, a giant holographic koi
drifting between towers, steady vertical camera rise, warm dusk gradient against
cool shadow, monumental futuristic mood, wind shear and distant drone whirr audio.

垂直升镜（ascent）最能表达”巨构建筑”的尺度，holographic koi（全息锦鲤）一个奇观点睛就够。

3 个技巧：让太空镜头立得住

1. 一镜一个硬光源。无过滤日光、地球反照、仪表辉光——选一个主光，让阴影彻底黑下去。太空光天生生硬；柔和环境光一出现就变成”室内”。
2. 每场戏给一个物理破绽。漂移的系绳、悬停下落的尘埃弧、漂浮水滴、永远不落定的布料。失重是一种”行为”，不是形容词。
3. 用好安静。太空片段靠稀疏音效取胜：amplified breathing、comms static、low cabin hum、deep sub-bass drone。声音之间的留白才是张力。

加餐：尺度词胜过形容词。IMAX-scale、planet-filling horizon、towering——一个尺度提示顶三个 “epic/majestic/breathtaking”。

FAQ

哪个模型最适合科幻太空场景？ 做同步声音设计（通信杂音、舱内低鸣、引擎充能声）优先 Veo 3.1；飞掠、升空这类长连续镜头 Kling 4.0 更稳；Seedance 2.5 适合把高质量太空静帧动起来；Hailuo 3 对金箔、面罩、尘埃这类硬材质细节表现不错。

为什么我的太空镜头像室内？ 九成是灯光和暗部问题。加上 harsh unfiltered sunlight、deep shadow with no fill、pure black starfield，并删掉提示词里所有 ambient / soft lighting。

失重感怎么写才可信？ 用多拍行为描述而不是一个词：tether drifting in slow lazy coils、tool bag floating just out of reach、zero-G cloth movement。凡是悬挂、盘绕、不肯下落的东西都在卖失重。

太空质感关键词有哪些？ volumetric nebula clouds、Earth's terminator line、helmet visor reflections、zero-G cloth movement、lens flare from a distant sun。这五个词基本解锁整个品类。

太空片段一定要音频吗？ 建议加，但要克制：comms crackle、amplified breathing、low cabin hum、deep sub-bass drone。真空场景靠声音稀疏制造张力，而不是靠音乐。

渲染完成后让它们跑起来：FLOWNIB 可以把做好的视频素材铺到多个平台，让一条轨道片段在各渠道都产生价值。
