AI 踩坑要点 👇

AI pitfalls 👇 Seedance 2.5: 1 render, $5.55 Finish level decides it, not nudity. The storyboard got blocked every time the clay body was smooth and fully detailed. Same figure left as rough, tool-marked, unfinished clay passed on the first try. Fix: refine only the face, keep the body mid-process. A finished nude reads as display. Rough clay reads as craft. Prompt 👇 15-second, 16:9 landscape, hyper-realistic live-action short. A young woman, Alessia, sculpts a life-size clay self-portrait in a grand old sculpture atelier, the most historic fine-art academy in Paris. A montage of one continuous sculpting session at real-time speed, each cut jumping forward in time so the clay figure is visibly more complete in every shot, her hands and forearms building up more grey clay smudges as it goes. Handheld documentary feel, filmed as if by chance: slightly imperfect framing, subtle handheld drift, gentle exposure breathing, autofocus arriving half a beat late. Use @reference as her locked visual identity - preserve her face, low bun, body proportions and outfit exactly across every shot, never reinterpret or let her face turn generic. Matte natural skin, real pores and fine peach-fuzz. Outfit, identical every frame: a fitted plain white short cropped t-shirt sitting high above the waist leaving the midriff bare, the thin soft stretch-knit clinging with real fabric creases across the bust and waist, short sleeves, plain crew neckline, worn over smooth seamless nipple covers so there is no protrusion or show-through; relaxed loose dark charcoal grey trousers on the hips, no branding. Warm chestnut brown hair in a low bun at the nape, a few loose face-framing strands at the cheeks. Grey clay smudges on her hands, forearms and one cheek. THE SCULPTURE - she is sculpting her own likeness: a life-size clay figure of Alessia herself on a metal armature and dark support posts. Its face, once sculpted, is a delicate likeness of her own but always turned lowered, three-quarter or in profile, never a sharp frontal face competing with the real Alessia. Its body stays a worked in-progress clay finish, tooled and undefined, no smooth skin, no anatomical detail, no defined nipples, never a smooth finished nude. It is ONE single identical sculpture across every shot, only its completeness changes, never its identity or size: the same life-size scale, the same upright standing pose, the same lowered-face orientation, the same low bun roughed into the clay, growing only from bare armature toward completed clay. CRITICAL: the real living Alessia is the ONLY subject with a sharp clear frontal face. The clay sculpture's face stays lowered and turned away, never a second frontal face. DIRECTION LOCK: the sculpture stays on frame-LEFT and Alessia works on its RIGHT throughout, the 180-degree line held, the space never flipping between cuts. Setting: a grand 19th-century fine-art academy sculpture atelier, tall arched windows with fine glazing bars, worn pale plaster and stone walls, a few classical white plaster casts along the far sides kept distant and clearly separate from her grey clay figure, scattered tools and cloths, a paint-marked work table, high ceilings, aged and lived-in, grand but working, never a clean empty film set. Lighting: soft natural daylight from the tall side windows as the single motivated source, gentle side falloff with smooth tonal transitions across her face and the clay, bright and airy but with real directional shadow, never flat dead light. No studio beauty light, no god-ray beams, no rim light. Face shadows stay soft but present, do not over-fill. She is calm, absorbed, focused on the work throughout, never posing for the camera, her figure seen only through the natural reach and stance of sculpting. 0-2.5s | EYE-LEVEL MEDIUM, slight handheld, already mid-motion: the sculpture is a bare metal armature with only the first handfuls of clay pressed on, no human shape yet. She presses and packs wet clay onto the upper frame, one arm reaching across, upper body leaning in, the white tee stretching across her, her focused gaze down on the work. 2.5-5.5s | LOW SIDE ANGLE looking up: the clay now reads as a rough human torso for the first time, coarse hand-pressed lumps. She reaches up high with both hands shaping the shoulder mass, one arm raised, body pitched forward onto the balls of her feet, her bare midriff and waist reading from the side through the reach. 5.5-8.5s | TIGHT CLOSE on her own face and hands together: the torso is fully formed now, and she carves the sculpture's lowered face into being with a small loop tool, its features just emerging as a likeness of her own, grey clay smudged on her cheek, her own eyes down, jaw set in concentration. Her real identity large and sharp. 8.5-11s | HIGH ANGLE over her shoulder looking down: the figure further along, its face roughed in and lowered, she drags a rib tool along the torso flank smoothing the coarse lumps into a cleaner worked surface, tool lines appearing, her back, waist and hip line reading in the twist of the reach, her own face lowered to the work. 11-13s | SIDE-PROFILE CLOSE on her face at eye level: the sculpture is now a near-complete clay self-portrait, face refined and lowered echoing hers, body a smooth-worked rough form. She has stepped back and stands side-on studying it, loose strands drifting at her cheek in the window light, chin lifted toward her own likeness, one hand wiping the other with a cloth. Her face large and sharp in clean profile. 13-15s | WIDE full pull-back establishing the whole atelier, the tall windows behind throwing the room into soft backlit depth: the completed life-size clay self-portrait stands on its posts on frame-left, face lowered, and she stands small on its right beside her own likeness, the grand old room and glowing windows visible, her small living figure the only scale reference beside the finished sculpture. Hold this wide as the final frame. AUDIO: all sound captured in-camera by a single handheld camera, raw, never a studio mix, never dubbed. Her quiet breathing, the soft wet press and pat of clay under her hands, the light scrape of the loop and rib tools on clay, a faint room tone of a large stone hall, distant muffled street sound beyond the windows. Natural and rough. No dialogue, no music, no BGM, no effect sound, no boom, kept low and real. Avoid: subtitles, text, watermark, anime, 3D-CG, plastic skin, over-beautifying, a smooth finished nude sculpture, defined nipples on the sculpture, a second frontal face on the sculpture, six different sculptures, changing sculpture size or pose, the sculpture flipping sides, posing for camera, nipple protrusion, slow motion, speed ramp, freeze, dramatic god-ray beams, studio beauty light, music, BGM, crowd, commentary.

AI 踩坑要点 👇 Seedance 2.5：一次出片，$5.55 决定能否通过的是完成度，不是裸不裸。 每次只要泥塑身体做得光滑、细节拉满，整个分镜就被卡。而同一个造型，留成粗糙、带工具痕迹、未完工的泥稿，一次就过了。解法：只精修脸部，身体保持半成品状态。 完工的裸体读起来像展示品；粗糙的泥稿读起来像创作过程。 提示词 👇 15秒，16:9 横画幅，超写实真人短片。一位年轻女性 Alessia，在巴黎最古老、最负历史声望的美术学院那间宏伟的老式雕塑工坊里，雕琢一尊真人大小的泥塑自画像。一段连续雕塑过程的蒙太奇，以真实速度推进，每个剪辑都向时间前方跳跃，泥塑形象在每一格里都明显更完整，她的双手和前臂上灰色泥渍越积越多。手持纪录片的观感，像偶然拍下的：略带不完美的构图、细微的手持漂移、柔和的曝光呼吸感、自动对焦总是慢半拍才咬住。 用 @reference 作为她锁定的视觉身份——每一镜都精确保留她的脸、低发髻、身体比例和服装，绝不重新诠释，也绝不让她的脸变得大众化。哑光自然肌肤，真实的毛孔和细细的绒毛。每一帧服装完全一致：修身纯白短款 T 恤，衣摆高过腰部、露出小腹，薄而柔软的弹力针织面料真实地贴合胸部和腰部，带着真实的褶皱，短袖，简洁的圆领，内里穿着光滑无缝的乳贴，确保没有任何凸起或透出；宽松随性的深炭灰色长裤低腰挂在胯部，无品牌标识。温暖的栗棕色头发在颈后挽成低发髻，脸颊两侧有几缕散落的发丝。手指、前臂和一侧脸颊上带着灰色泥渍。 雕塑本体——她正在雕琢自己的肖像：一尊真人大小的 Alessia 本人的泥塑，架在金属骨架和深色支撑柱上。它一旦被雕出脸部，便是她本人的精致写照，但始终保持低垂、三向以下或侧脸朝向，绝不会出现一个清晰的正面脸去和真实的 Alessia 争抢视觉焦点。它的身体始终保持制作中的泥稿状态，带着工具痕迹、未完成、不光滑、没有解剖细节、没有明确的乳头，绝不是光滑完工的裸体。整条片子从头到尾都是同一尊、完全一致的雕塑，只有完成度在变，身份和尺寸不变：同样的真人比例、同样的直立站姿、同样的低垂脸部朝向、同样的低发髻粗坯入泥，只从光秃骨架向完成泥稿生长。 关键：真实在场的 Alessia 是全场唯一拥有清晰锐利正面脸的主体。泥塑的脸始终低垂并偏转，绝不能出现第二个正面脸。 方位锁定：雕塑始终在画面左侧，Alessia 始终在它的右侧进行工作，整条片保持 180 度轴线，剪辑之间空间绝不翻转。 场景：一座宏伟的 19 世纪美术学院雕塑工坊，高高的拱形窗户带着纤细的窗格条，磨损的浅色灰泥与石墙，远端沿墙摆放少量古典白色石膏像，始终保持距离、与她的灰色泥塑明显分开，零散的工具和布块，一张带颜料的工桌，高高的天花板，陈旧而充满生活气息，宏伟却在使用中，绝不是干净空旷的片场布景。 光线：来自高侧窗的柔和自然日光作为唯一有动机的光源，柔和的侧面衰减，她的脸和泥塑表面过渡平滑，明亮通透但带真实的方向性阴影，绝不死平。没有影楼美人光、没有丁达尔光柱、没有轮廓光。面部阴影柔和但存在，不要过度填充。 她全程平静、专注、沉浸在工作中，绝不为镜头摆拍，她的身形只通过雕塑动作自然的伸展与站姿呈现。 0–2.5 秒｜平视中景，轻微手持，已在动作之中：雕塑是光秃的金属骨架，只压上了最初几团泥，尚无人形。她将湿泥压实到上部骨架上，一只手臂跨过去探，上身前倾，白色 T 恤随之拉伸，她专注的目光垂向作品。 2.5–5.5 秒｜低角度侧拍，仰视：泥塑首次呈现出粗略的人体躯干轮廓，是粗糙手压的泥团。她双手高举塑造肩部块面，一只手臂抬起，身体前倾用前脚掌支撑，裸露的小腹和腰线从侧面通过伸展的姿势被读取。 5.5–8.5 秒｜紧贴特写她自己的脸和手：此时躯干已完全成型，她用一把小环形工具雕出雕塑低垂的脸部，五官刚刚浮现出她自己的神韵，灰色泥渍沾在她的脸颊上，她本人的双眼低垂，下颌紧绷、神情专注。她真实的身份清晰锐利，占据画面主体。 8.5–11 秒｜越过她肩部的高角度俯拍：人物进展更大，脸部粗坯已成且低垂，她沿躯干侧腹拖动肋形工具，把粗糙的泥块刮成更干净的工作面，工具痕迹浮现，她的背、腰和胯线在扭转的伸手姿势中被读取，她本人的脸也低垂朝向作品。 11–13 秒｜平视侧面特写她的脸：雕塑此时已接近完成，是泥塑自画像，脸部精修完成且低垂，与她本人相呼应，身体是光滑处理过的粗坯形态。她已后退一步，侧身站着审视它，散落的发丝在窗光中拂过她的脸颊，下颌微微抬起朝向自己的肖像，一只手拿布擦拭另一只手。她的脸在干净的侧脸轮廓中大而清晰。 13–15 秒｜大全景拉出，建立整个工坊全景，身后高窗把房间投入柔和的逆光纵深：完成的真人大小的泥塑自画像立于其支撑柱上，位于画面左侧，脸部低垂，她渺小的身影站在右侧自己肖像的旁边，宏伟的老房间与发光的窗户清晰可见，她那小巧的在场身影成为雕塑旁唯一的比例参照。把这个全景作为最后一帧保持。 音频：所有声音由单台手持摄影机同期收音，原始质感，绝不做后期混音，绝不另录配音。她轻柔的呼吸、双手下湿泥被压实的轻响、环形与肋形工具在泥上的轻刮、大石质厅堂里微弱的空间底噪、窗外远处模糊的街声。自然而粗粝。无对白、无音乐、无 BGM、无音效、无吊杆话筒，保持低音量、保持真实。 避免：字幕、文字、水印、动画风、3D CG、塑料感皮肤、过度美化、光滑完工的裸体雕塑、雕塑上明确的乳头、雕塑上的第二个正面脸、六尊不同的雕塑、雕塑尺寸或姿势变化、雕塑左右翻转、为镜头摆拍、乳头凸起、慢动作、速度斜坡、定格、戏剧化的丁达尔光柱、影楼美人光、音乐、BGM、人群、解说词。
