仅文本,15 秒,16:9。提示词要求一个环绕镜头、闪电、由碎片组装的锤子,以及最后的广角画面。


Seedance 2.5 从特写到结尾保持同一张编着辫子的脸。手唤来闪电,身体被一道光柱罩住,最后一个镜头是山顶上的广角,锤子已经举起。没有展示碎片融合成锤子。
Seedance 2.0 把中段镜头做得更大:人物在岩石之间的闪电漩涡里漂浮。结尾也有锤子,但身体悬在坑的上方,双脚看起来站不稳。它没有落到那个人物站定的广角镜头。
在意同一张脸和最终构图时,用 2.5 的片段。在意闪电的规模时,用 2.0 的片段。
A high-concept mythological action VFX cinematic spectacle shot on Sony Venice 2 with Cine Alta 8K sensor and Leica Summilux-C lenses, featuring photorealistic golden lightning arc flashes, dynamic ray-traced particle physics, floating terrestrial debris, and glowing ancient divine runes illuminated by hyper-detailed volumetric atmosphere. The continuous, seamless 360-degree whip-pan camera begins in a low-angle orbital sweep around a muscular, bearded Norse god suspended in mid-air above a fractured obsidian mountain shrine under a tempestuous crimson sky. His initial solemn and stoic composure dramatically shifts into furious rage as his eyes burst into blinding blue plasma energy, casting vibrant specular highlights across his weathered skin and braided hair. As the camera accelerates its continuous spiral rotation around the god, he lets out a guttural, thunderous roar, raising his right hand to summon violent streaks of celestial lightning that erupt from swirling storm clouds. The raw electrical arcs violently pull floating stone fragments and divine liquid metal together into a swirling vortex, instantly fusing them into a massive, glowing, runic-engraved battle hammer in his fist. Upon gripping the weapon, he detonates a massive radial gravity shockwave that instantly pulverizes the surrounding floating boulders into fine stardust particles and ripples through the thick atmosphere, leaving the ancient fractured shrine beneath him pulsing with deep blue subterranean magic. The unbroken dynamic shot completes its orbital loop to settle into a dramatic wide hero framing of the god hovering amidst the dissipating energy dust, legendary, majestic, thunderous, and escalating from tense stillness to an overwhelming explosive climax.

Seedance 2.5 展示了走近的过程:两个人走过咖啡馆,停下来交谈,然后走到门前。门向外打开。结尾时他已经在里面,她跟随进入,这和所要求的顺序相反。
Seedance 2.0 在门这一段更清楚。他扶着两扇门,她走在他前面进去。服装全程保持不变。
进门用 2.0 的片段。街道上的走近过程和向外开的门,用 2.5 的片段。

Pixar-style 3D animation, style locked to <<<Image3>>> , <<<Image1>>> and <<<Image2>>> — render everything exactly in their look. HAORAN, the young man from <<<Image1>>> , and XIAOYU, the young woman from <<<Image2>>> , run into each other on the sidewalk in front of the café from <<<Image3>>> , both breaking into surprised, warm smiles. XIAOYU says: "Haoran? What a coincidence!" He laughs: "First time seeing you since graduation!" She replies: "Come on in, coffee's on me." He answers: "Let's go." They walk up the steps together; HAORAN pulls the right door leaf outward by its brass handle — hinges on the outer edge — and holds it open as XIAOYU steps inside, then follows her in as the door swings shut behind them. Soft rounded stylized character proportions, subsurface scattering on skin, large expressive animated eyes, warm golden-hour cinematic lighting, gentle squash-and-stretch motion. The camera tracks them from across the street with a slow push-in. Dialogue in English with accurate lip sync, no subtitles. Avoid photorealistic faces, live-action look, 2D cel-shaded style, any style shift mid-clip, doors opening inward, sliding doors, or extra background characters entering frame.
仅文本,15 秒,16:9,固定内景。


Seedance 2.5 保持同一辆车、开车的柴犬、灰猫、浣熊和篮子。一只鸭子入画,一颗葡萄出现。它没有演出可颂帽的交接。灰猫戴着甜筒,西瓜放在浣熊身上。
Seedance 2.0 在开场画面里对上了更多道具:西瓜帽、可颂、鸭子、手机,以及正在唱歌的柴犬。几秒之内柴犬消失,乘客换了,车子短暂地几乎空掉,然后一组重新安排的角色回来。
用 2.5 的片段。2.0 的开场道具更全,但这段其余部分没有停在同一个场景里。
Hyper-realistic wool-felt plush texture, cottagecore pastel palette, matching the reference image exactly. Fixed camera locked at this exact interior angle, no cuts, no camera movement. A hilarious and heartwarming 15-second road trip scene bursting with individual personality. [0-4s] The shiba inu driver is having the time of her life — head bobbing to music, singing loudly with mouth wide open, one paw drumming the steering wheel. The watermelon-hat cat films a selfie video, the duck photobombs by suddenly stretching its neck into frame with a loud honk, the cat rolls its eyes dramatically. The raccoon shakes its iced drink like a cocktail, ice cubes rattling. [4-8s] Sharp left turn! A comedic chain reaction: the croissant hat slides off the grey cat's head and lands on the bonnet kitten's face, covering its eyes — the kitten flails its tiny paws in confusion. The poodle slides across the back seat and squishes the bichon against the window, both bursting into laughter. The duck slides sideways with a deadpan expression, completely unbothered, like it has seen everything. [8-12s] Bumpy road! Everything bounces — a grape pops out of the picnic basket, flies through the air, and the raccoon catches it in its mouth mid-bounce, looking extremely proud of itself. One kitten in the pink basket gets bounced awake, grumpily grabs the edge of the basket, gives everyone an annoyed squint, then dramatically flops back down into the basket. The goldfish leaps out of the sloshing water and splashes back in. [12-15s] The road smooths out into warm golden light. All animals perk up, bright-eyed and alert, turning toward the camera with big open-eyed smiles — the shiba driver glances back with a wide grin and a thumbs-up paw, eyes sparkling; the croissant cat retrieves its hat, puts it on backwards without noticing, and blinks curiously at the camera; the bonnet kitten hiccups a tiny flower petal and giggles with wide shining eyes. Everyone stays awake, lively and energetic, eyes wide open, looking around cheerfully as sunset light glows on their fur. Every animal has exaggerated theatrical acting with natural fur physics — wide eyes, flattened ears, wagging tails, puffed cheeks, dramatic reactions, while rendering stays fully realistic plush-felt style throughout. All characters keep their eyes open and alert throughout, except the basket kittens. Blurred mountain scenery streams past the windows, tree shadows flicker across the interior.

Seedance 2.5 保持同样的五套服装。这组人向前移动,大约在 12 秒时排成一列坐下。到最后一帧,中间的舞者又回到前面,所以新队形没有保持住。
Seedance 2.0 在片段中段给出更大的个人舞蹈姿势。结尾接近开场的 V 字,而不是排成的一列。
队形变化重要时,用 2.5 的片段。想要更大的舞蹈姿势,并且接受结尾回到旧队形时,用 2.0 的片段。

The five dancers from <<<Image1>>> , keeping each dancer's exact face, hairstyle and outfit, perform street dance in the graffiti plaza, choreographed to the music in <<<Audio1>>> , every move landing on the beat. Formation change is required: starting in the V-formation from <<<Image1>>> , midway through the clip all five dancers travel to new positions — the center dancer moves to the back as the other four sweep forward into one horizontal line, finishing the routine in this new formation. Camera movement mirrors the music's rhythm and energy. Continuous single take. Use the ORIGINAL audio from <<<Audio1>>> unchanged; audio reference only, not visual reference. Avoid generated music, added sound effects, cuts, face distortion, identity swapping, subtitles, dancers standing in place for the whole clip.

Seedance 2.5 保持安静的划船镜头:蓝色小船、柳树、握桨的水鼠、坐在船尾的鼹鼠。然后切到船内。水鼠已经躺在船底,河岸不在画面里。
Seedance 2.0 演出了撞击。水鼠划船,鼹鼠坐在对面,船头撞上河岸,水鼠向后倒下、双脚朝上,鼹鼠在旁边看着。

A fifteen-second continuous shot, Edwardian pastoral watercolor style, soft riverside light. A water rat sculls a small rowing boat, painted blue outside and white within, along a gentle river, with a mole seated in the stern, exactly as the original text describes: "Believe me, my young friend, there is nothing—absolute nothing—half so much worth doing as simply messing about in boats. Simply messing," he went on dreamily: "messing—about—in—boats; messing—" "Look ahead, Rat!" cried the Mole suddenly. It was too late. The boat struck the bank full tilt. The dreamer, the joyous oarsman, lay on his back at the bottom of the boat, his heels in the air. "—about in boats—or with boats," the Rat went on composedly, picking himself up with a pleasant laugh." — Kenneth Grahame, The Wind in the Willows (1908), Chapter I, Project Gutenberg #27805 (Scribner 1913 ed.)

Seedance 2.5 把顺序保持得清楚:机甲胸口的低角度、导弹从机甲肩部飞出、女主角爬上装甲,然后正面击中发光核心。结尾是能量爆发,不是玩具外壳解体。
Seedance 2.0 开头能清楚看成全身,结尾碎成彩色玩具零件。朝镜头跑来,以及爬到头上,打断了这条路径;侧面的爆炸没有展示导弹离开机甲。

Toy-world giant boss battle CG, 15 seconds, one continuous take. Input references: <<<Image1>>> for character appearance — TOPVIEW BOT PRO exact costume and palette <<<Image2>>> for boss appearance — TITAN UNIT-01 final giant form, exact design and palette References are design sheets only: do NOT render the sheet layout, labels, swatches, scale panel or grey background. Extract character design only. Character lock (match <<<Image1>>> exactly, no changes): A small agile girl TOPVIEW BOT PRO with long silver-white hair in loose low twin tails, pale mauve eyes, calm focused expression. Yellow cat-ear cap with black inner ears and black cat face emblem, black and hot pink headphones with heart marks, heart earrings. Oversized yellow bomber jacket with black cat patches, PRO badge, X badges and pink hearts, white-black cropped top, pink belt with heart buckle, black shorts, pink heart mark on her thigh, mismatched socks, chunky yellow platform sneakers with pink soles. She carries a huge yellow and black toy cannon with pink handle and X markings, connected by pink cables to a back tank. Color palette locked: yellow #FFD400, hot pink #FF4D79, black #1A1A1A, white, grey. Boss lock (match <<<Image2>>> exactly): A hundred-meter toy titan mech in its tall heroic giant form, glossy injection-molded plastic and diecast materials, dense overlapping armor plates with oversized screws and molded seams. Deep grey and matte blue armor, blue helmet with hot pink crest raised above broad flat shoulder decks, glowing yellow eye visor, shoulder missile pods with yellow-black warning stripes and pink missile tips, pink-yellow energy lines, glowing chest core with pink X emblem set into layered chest armor plates forming flat ledges at varying heights — standable plates, deep seams, no man-made stairs or ladders. The titan is an active aggressive fighter: its head tracks her constantly, its fists strike and grab at her throughout the fight, servos whining with every motion. Environment: giant toy city battlefield — building blocks, gift boxes, toy trains, a Ferris wheel, teddy bears, plastic debris; realistic grey-white skyscrapers behind, bright blue sky, floating confetti. Timeline: 0.0–3.0s | Face-off Opening frame: seen from a low angle behind her — TOPVIEW BOT PRO stands with her back to the camera on a wide flat armor ledge beside the glowing X core, tiny against the titan's mass, facing up toward the helmet far above. Wind blasts through her twin tails and yellow jacket. She levels her cannon at the distant glowing visor. The titan's head tilts down, visor locking onto her and narrowing to a bright slit; both shoulder missile pods snap open with mechanical clicks. Camera: low-angle over-the-shoulder push-in past her toward the titan's head — her back to camera in the near foreground, the helmet towering above, shallow depth of field. 3.0–8.0s | Homing missile gauntlet The shoulder pods fire: missiles arc high into the sky trailing white smoke, then curve sharply downward and home in on her, chasing her path. She sprints up the titan's chest across overlapping armor plates, vaulting ledge to ledge as the homing missiles slam into the armor just behind her footsteps, each impact exploding into colorful plastic debris. The titan's left fist sweeps across its own chest to swat her — she slides under the passing fist without breaking stride, then fires once on the run, destroying the last missile behind her. Camera: fast side-tracking shot rising with her, wide lens, heavy motion blur, the sweeping fist and missile impacts crossing the foreground. 8.0–15.0s | Face-to-face point-blank finish As she reaches the shoulder deck, the titan's right hand rushes in to grab her — she leaps off the closing fingers, using the hand as a springboard, arcs through the air IN FRONT of the titan's face, and lands on the narrow brow ledge directly above the glowing yellow visor. She faces the titan's face head-on — her body turned OPPOSITE to the direction the titan faces, her back to the open sky, the huge visor glowing right in front of her. She presses the cannon muzzle horizontally against the center of the visor. The weapon charges yellow-pink energy for one beat while the titan thrashes — then she fires the beam horizontally straight INTO the face. The visor shatters inward, colorful energy bursts through every helmet seam, and the titan breaks apart into thousands of flying toy blocks and plastic pieces. She kicks off the collapsing face through the falling debris, landing on a giant tumbling block, still running forward. Camera: following her leap around to the FRONT of the titan's face, holding a frontal close shot — girl and giant face in the same frame, facing each other — during the charge and firing, then pulling wide as the mech shatters; follow her momentum through the debris. End frame: cut during her run across the falling blocks — no victory pose, no freeze frame, no fade. Style: AAA game boss battle trailer, stylized anime-inspired 3D CG, glossy toy materials, Ratchet & Clank + Astro Bot energy, extreme scale contrast between the small girl and the colossal mech, high saturation, cinematic rim light, physical debris simulation, motion blur, 24fps anamorphic widescreen. Audio: fast electronic rock, heavy drums, toy-box chimes, servo sounds, missile launch whooshes, homing missile whistles, sliding metal scrapes, cannon charge whine, massive beam impact, cascading plastic destruction; music cuts off mid-action. Avoid static camera, slow pacing, scene reset, character facing the camera in the opening shot, girl facing the same direction as the titan's head, girl standing on top of the head firing outward into empty sky, beam firing away from the titan, missiles flying away in straight lines, missiles appearing from off-screen without being launched, passive motionless boss, staircases, man-made steps, ladders, handrails, character redesign, hair or costume color change, blue jacket, bunny ears, weapon redesign, chibi proportions on the mech, rendering the reference sheet layout or text, extra limbs, distorted face, bad hands, subtitles, watermark, UI, gore, desaturated colors, slow-motion ending.
我们的对比框架关注提示词遵循、角色一致性、动作连贯、音频同步,以及实际可用性。
这 6 个场景覆盖电影级特效、对白、群戏、舞蹈同步、文学叙事和游戏动作。
计划中的基准是:较简单的任务每个模型生成 3 次,较复杂的任务每个模型生成 5 次,两个模型合计 52 次生成尝试。
两个模型使用相同的提示词和参考素材;在双方都支持的地方,时长、分辨率、宽高比和音频设置保持一致。
我们保留每一次提交的任务,包括失败的生成和被拒绝的输出。
每条已完成的视频都按预先定好的评分标准独立评估。
为避免只挑视觉上好看的结果,代表用的基准输出按其接近该模型、该场景盲评质量中位分的程度来选取。
另外的营销展示可能会使用得分最高的输出,但这些会明确标为精选示例。
即使提示词相同,单次视频输出在不同生成之间也可能不一样。
这个基准用来帮创作者理解实际取舍,而不是声称其中某个模型普遍更优。
