AI pitfalls 👇 Seedance 2.5: 1 render ~$3.70 Lock the set with its own reference image. Let the model build the background and it rebuilds the room every cut: windows drift, walls change, a hatch reshapes itself shot to shot. Learned that the hard way before, so this time we generated one separate image of the empty set and fed it as its own reference: "match it exactly, never redraw the set." The station stayed identical in every shot. The model doesn't remember your background. Give it a picture to copy. Prompt 👇 10-second, 16:9 landscape, hyper-realistic live-action short. A young woman, Alessia, drifts through a space station module in microgravity, reaches a cupola observation dome, and sees Earth below. Use @character as her locked visual identity - preserve her face, body proportions and outfit exactly across every shot, never reinterpret or let her face turn generic. Matte natural skin. Use @cupola as the locked environment - the module interior and the cupola dome match it exactly across every shot, same walls, same dome, same Earth beyond the glass, never redraw or reinterpret the set. HAIR: warm chestnut brown hair worn loose and shoulder-length, floating and lifting weightlessly in microgravity, strands drifting slowly and softly around her face the whole time, never falling flat as if under gravity. OUTFIT (identical every frame): a fitted deep slate-blue technical loungewear set, station-issue - a slim-fit long-sleeve top in smooth matte technical knit following her frame cleanly, raglan shoulder seams, a single thin pale cool-grey trim line at the cuffs and collar as the only accent, and matching slim-fit long knit pants. Thick smooth lined fabric, fully opaque with a smooth even front surface and no protruding detail, no branding, no logos, no glow, no LED. She is a calm trained operator, deliberate and economical in every movement, never a panicking or struggling person. Her body carries a relaxed weightless neutral posture throughout - shoulders slightly raised, limbs loosely drawn in and softly bent, never rigidly straight, never a stiff diving arrow shape, the natural resting float of a real body in microgravity. DIRECTION LOCK: she always travels toward the same side of frame, drifting rightward and forward toward the cupola. Her direction of travel never reverses across any cut. When the camera moves in front of her it has circled around to face her while she still advances toward the cupola - she never turns back, never doubles back, the 180-degree line is held across every shot. Interior of a modern space station per @cupola: clean minimal architecture, smooth matte pale-white curved module walls, recessed lighting, hidden cabling, handrails along the walls, uncluttered, leading to the rounded multi-window cupola dome at the end. Beyond the dome the curved edge of planet Earth glows enormous and blue below - deep blue oceans, white cloud swirls, the thin bright atmosphere line against black space. Earth is the single colossal object dominating the view, dwarfing her to the only human-scale reference in frame. One single motivated light source only: the cold blue-white light of Earth and sunlight spilling in through the cupola glass. Her face is lit only by this cold Earth-glow, hard natural chiaroscuro, deep shadows through the module interior, face not specially lit, shadows stay dark, do not fill. No studio light, no beauty light, no rim light, no god-rays. The slowness is real microgravity physics, never slow motion or speed ramp: her body carries genuine weightless inertia, her loose hair and clothing drift with the movement and settle a beat late, everything floats and glides. Real-time speed, only weightlessness makes it slow. Multi-camera coverage: shallow-depth handheld close, wide side tracking, over-the-shoulder approach, long-lens push-in. Raw in-camera documentary look, soft early-HD image, mild grain, slight TV compression. One continuous module, one continuous event, each cut picking up exactly where the last left off. 0-2.5s | SHALLOW-DEPTH HANDHELD CLOSE-UP, the module blurred soft behind her, slight organic handheld drift: her face fills the frame, loose hair floating and fanning weightlessly around her, one hand already mid-motion sweeping a drifting strand back from her cheek, her eyes flicking to the lens then away, calm and unhurried. The face-lock beat - only her, sharp against the soft blurred interior, held long enough to read her face clearly. 2.5-5.5s | WIDE SIDE TRACKING, pure lateral profile: she pushes off a handrail and glides forward through the module, her whole body oriented horizontally along her line of travel toward the cupola, not standing upright, floating lengthwise through the space in a relaxed neutral posture, hair and loose strands streaming slowly behind with the inertia, clothing shifting a beat late, the pale module walls sliding past and Earth's blue glow beginning to wash in from the far end ahead of her. 5.5-8s | OVER-THE-SHOULDER from behind as she reaches the dome, then the camera circles to a MEDIUM SIDE angle in front of her: one hand catches the rim of the cupola and arrests her drift, her body swinging gently around the grip and settling to a soft stop at the glass, still facing the dome. The camera continues to a WIDE REVERSE from inside the dome looking back at her: Earth fills the windows below and around her, the vast curved blue planet with slow cloud swirls and the glowing atmosphere line, her small floating figure the only scale against the enormous mass, immense negative space around her. 8-10s | LONG-LENS TIGHT on her face, lit only by the cold blue Earth-glow, her expression settling into quiet genuine awe - eyes wide and still, lips barely parted, no smile, the overview-effect moment landing on her face as pure stillness. The camera pushes slowly and physically inward toward her eyes and nose, her face staying fully recognizable, until a small curved reflection of blue Earth is caught glinting in her eye. Hold on her eyes as the final frame, real and understated. Every beat shows clear physical cause and weightless response. Single continuous real-time take, cuts decisive and clean. AUDIO: all sound captured in-camera by a single handheld camera, raw and real, never a studio mix, never dubbed, no cinematic sound design, no sci-fi ambience, no dramatic hollow space silence. Only the real mechanical sound of the station air-circulation and ventilation fans running, the faint airflow, her quiet steady breathing, the soft rustle of her drifting hair and clothing, and one muffled dull contact when her hand meets the cupola rim. A close, dry, enclosed-cabin soundfield - sounds are near and slightly muffled, not spacious or reverberant. The slow push-in on her eyes falls to near-silence, just her breath. No music, no BGM, no score of any kind, kept low and real. Avoid: subtitles, text, watermark, dark and unreadable, anime, 3D-CG render look, plastic skin, over-beautifying, studio beauty light, dramatic god-ray beams, spacewalk suit, helmet, full-face mask, panicking, struggling for air, distress, thrashing, rigid straight diving posture, standing upright while floating, floating debris clutter, hair falling flat under gravity, direction reversal, turning back, music, BGM, score, sci-fi ambience, cinematic sound design, hollow reverb, crowd, commentary, dialogue, spoken lines, slow motion, speed ramp, freeze, rack focus, focus pull, effect sound, boom.

AI 踩坑指南 👇 Seedance 2.5：1 次渲染约 $3.70 用专属参考图锁死场景。让模型自己搭建背景的话，它每条剪辑都会重建整个房间：窗户会漂移，墙体会变化，舱口在每个镜头里都会变形。之前就吃过这个亏，所以这次我们单独生成一张空置场景的图，作为它自己的参考输入：“完全匹配，绝不要重画场景。”结果空间站在每个镜头里都保持了一模一样。 模型记不住你的背景。给它一张图去照抄。 Prompt 👇 10 秒、16:9 横构图、超写实真人短片。年轻女性 Alessia 在微重力中飘行穿过一座空间站舱段，抵达一个穹顶观察舱，透过穹顶玻璃看见下方的地球。使用 @character 作为她锁定的视觉身份——在每一个镜头中精确保留她的面部、身材比例和服装，绝不能重新诠释，也不能让她的脸变得大众化。哑光自然肌肤。使用 @cupola 作为锁定的环境——舱段内部和穹顶舱在每个镜头中都要与它完全匹配，同样的墙体、同样的穹顶、同样的玻璃外的地球，绝不能重画或重新诠释场景。 头发：暖栗棕色头发，自然披落，长度及肩，在微重力中飘起浮升，发丝缓慢柔和地在她脸庞周围飘动，绝不能像在重力下那样平贴垂落。 服装（每一帧完全一致）：一套合身的深石板蓝色技术感家居服，空间站配发——一件修身长袖上衣，采用光滑哑光的技术针织面料，干净地贴合身形，插肩袖缝合，袖口和领口各有一条纤细的冷浅灰色装饰线作为唯一点缀，搭配同款修身长针织裤。面料厚实顺滑带衬里，完全不透光，正面平整均匀，没有任何突出的细节，没有品牌标识，没有 logo，没有发光，没有 LED。 她是一名沉稳、受过训练的操作员，每一个动作都从容而克制，绝不是惊慌失措或挣扎挣扎的人。她的身体全程保持放松的失重中性姿态——肩膀微微抬起，四肢自然收拢、柔和弯屈，绝不僵直笔直，绝不是僵硬箭头的跳水姿态，而是一个真实的人在微重力中自然的静止漂浮状态。 方向锁定：她始终向画面的同一侧移动，向右并向穹顶方向向前飘去。她的行进方向在任何剪辑之间都绝不反转。当摄像机移到她正面时，是绕到了她的前方来面对她，而她依然在向穹顶前进——她绝不转身，绝不折返，180 度轴线在每个镜头中始终保持。 现代空间站的内部，参 @cupola：极简洁净的建筑感，光滑哑光的浅白色弧形舱壁，嵌入式照明，隐藏式线缆，沿墙安装扶手，干净无杂物，尽头是带多扇窗户的圆形穹顶观察舱。穹顶之外，行星地球弯曲的边缘在下方发出巨大而湛蓝的光芒——深蓝色海洋，白色云卷，黑色太空边缘一道纤细明亮的大气线。地球是画面中唯一巨大的主导天体，把她压缩为画面中唯一人类尺度的参照。 仅有一束有依据的光源：从穹顶玻璃透进来的地球与太阳的冷蓝白色光。她的脸只被这道冷冽的地球辉光照明，硬朗自然的明暗对比，舱段内部阴影浓重，面部不做特别补光，阴影保持深邃，绝不补亮。没有影棚灯，没有美颜灯，没有轮廓光，没有丁达尔光柱。 缓慢感来自真实的微重力物理，绝不是慢动作或变速加速：她的身体带着真实的失重惯性，松散的头发和衣物随着动作飘动并稍晚一拍落定，一切都在漂浮、滑行。实时速度，唯有失重让它显慢。多机位覆盖：浅景深手持近景、宽幅侧向跟随、过肩接近、长焦推入。机内直录的纪录片质感，柔和的早期高清画面，淡淡的颗粒感，轻微的电视压缩感。单一连续舱段，单一连续事件，每次剪辑都正好接上上一次停下的位置。 0-2.5s | 浅景深手持近景，舱段在她身后柔和虚化，带轻微自然的手持飘移：她的脸填满画面，松散的头发失重般漂浮展开，一只手已经在半途中把一缕飘动的发丝从脸颊拂开，她的眼神短暂瞥向镜头再移开，沉着不慌。面部锁定的节拍——只有她，在柔和虚化的舱内背景前清晰锐利，保持足够长的时间让观众清晰看清她的脸。 2.5-5.5s | 宽幅侧向跟随，纯粹的侧向剖面：她推离一根扶手向前滑过舱段，整个身体沿向穹顶的行进方向水平展开，并不直立，而是以放松的中性姿态沿空间纵长方向漂浮，头发和松散的发丝因惯性在身后缓缓拖曳，衣物稍晚一拍地移动，浅色舱壁从旁滑过，地球的蓝色辉光开始从前方远处的舱段尽头漫入。 5.5-8s | 从后方过肩拍摄她抵达穹顶，然后摄像机绕到前方的中景侧角：一只手抓住穹顶边缘刹住了她的飘移，身体绕着力点轻轻荡起并柔和地停在玻璃前，依然面朝穹顶。镜头继续绕到从穹顶内部向外回望的宽幅反向机位：地球填满她下方和周围的窗户，巨大弧形的蓝色星球缓缓翻卷着云层、闪亮的大气线，她微小漂浮的身影是这片巨大体量中唯一的尺度参照，周围是巨大的负空间。 8-10s | 长焦紧贴她的脸，只有冷蓝色的地球辉光照亮，她的表情沉淀为安静、真实的敬畏——眼睛睁大而静止，嘴唇微微张开，没有微笑，全景效应的那一瞬以纯粹静止落在她的脸上。镜头缓慢而真实地物理性向她的眼睛和鼻部推入，她的脸始终保持完全可辨识，直到捕捉到一小弯蓝色的地球反光在她眼中闪动。定格在她的眼睛作为最后一帧，真实而克制。 每一个节拍都展现清晰的物理因果与失重响应。单一连续的实时镜头，剪辑果断干净。 声音：所有声音均由单一手持摄影机机内直录，原始真实，绝非影棚混音，绝非后期配音，没有电影化的声音设计，没有科幻环境声，没有戏剧化的空旷太空寂静。只有空间站空气循环与通风风扇的真实机械声、轻微的气流声、她平静稳定的呼吸声、飘动头发和衣物柔和的窸窣声，以及当她的手触到穹顶边缘时一声闷哑的接触音。一种贴近、干燥、封闭舱内的声场——声音近且略带闷感，绝不空旷，绝不带有混响。镜头缓慢推向她眼睛时声音渐近于近乎寂静，只剩她的呼吸。没有音乐，没有 BGM，没有任何形式的配乐，保持低调真实。 避免：字幕、文字、水印、过暗看不清、动画风、3D-CG 渲染感、塑料感肌肤、过度美化、影棚美颜灯、戏剧性丁达尔光柱、太空行走服、头盔、全脸面罩、惊慌、挣扎求氧、痛苦、狂乱挣扎、僵直笔直的跳水姿态、漂浮时却直立站立、漂浮碎片杂物、头发在重力下平贴垂落、方向反转、转身回头、音乐、BGM、配乐、科幻环境音、电影化声音设计、空旷混响、人群、解说、画外音、对白、念白、慢动作、变速、冻结、拉焦、变焦、效果音、挑杆。
