Flatkey Uses Seedance to Generate a 15-Second Multi-Character Dance Video

English text is being prepared.

AI summary

The author called the Seedance model on Flatkey and generated a 15-second dance video featuring multiple characters in the same frame, with Sam Altman and Dario Amodei dancing side by side; the actual cost was under $0.1. The author shared three Prompt pitfall-avoidance parameters: use absolute positioning to lock down character features to prevent face swapping, unify the choreography rhythm to prevent limbs from melting, use a 35mm wide-angle cinematic lens to keep the characters on the same focal plane, and add a no face morphing constraint. Flatkey's everyday pricing is at least 20% lower than official pricing, failed requests cost $0, and it provides access to 100+ official models.

Everyone stand up!! Open-sourcing my 8-dimensional advanced exclusive AI beauty portrait generation secret formula!! (Including the exclusive top-tier beauty portrait prompts that I, a 10-year veteran portrait photography master, polished with Fable 5.5) Brothers, have you ever wondered why the AI portraits you generate always have a greasy plastic feel and a fake-person vibe? Because you're still using vague adjectives instead of using real photographic physical language to constrain the AI. This AI image generation framework and batch pipeline, distilled across 8 dimensions, can thoroughly push AI visual quality to a top-tier level. Follow this framework and plug in the terms, and the resulting quality is maxed out instantly: 1️⃣ Temperament and tonal mood define the persona: reject vague pretty labels, and anchor the aura with specific class temperament, e.g., 25-year-old East Asian woman, old-money relaxed elegance, editorial fashion portrait. 2️⃣ Fabric drape replaces blunt description: premium feel comes from the weight of physical materials, e.g., raw silk, fitted merino knit, subtle collarbone shadow, tailored silhouette. 3️⃣ Candid micro-expressions eliminate dead-fish eyes: specify the real emotion of the moment to completely say goodbye to stiff posing, e.g., candid moment, soft knowing glance, caught mid-reaction, unaware of the camera. 4️⃣ Cinematic optical lens language: give the image the optical depth of field of a real camera, e.g., 85mm portrait lens, f/1.8 shallow depth of field, subtle film grain, natural optical compression. 5️⃣ Directional lighting sculpts the skin's breathing feel: use side light and rim light to retain real pore texture, e.g., soft diffuse directional light, gentle rim light, authentic skin texture with visible pores and natural highlights. 6️⃣ Soft defocus brings out the subject: the environment must be restrained with depth-of-field layering, e.g., soft morning cafe ambiance, muted warm background bokeh, natural depth. 7️⃣ Restraint and ease lock in the aesthetic floor: reject exaggerated features and heavy makeup, pursue natural and enduring beauty, e.g., classy, effortless beauty, understated luxury, natural proportions. 8️⃣ Industrial-grade negative words build a firewall: forcibly block all kinds of distortion and CGI texture, and lock out no plastic skin, no doll face, no extra limbs, no 3D render look, no over-smoothed texture. With good prompts, how to batch-test at extremely low cost and get the workflow running is the key to continuously growing an account. Opening memberships for different tools everywhere every day not only costs a high monthly fee, but frequently switching between backends also shatters all creative rhythm. The multimodal foundation I've mainly been running recently is Flatkey (1). For people who tinker with multimodal creation and batch image generation every day, it is indeed currently the most worry-free and cost-effective solution: → Official models, lower cost: everyday pricing is at least 20% lower than direct official access, and the most practical part is that failed requests are billed at $0, so multi-round prompt debugging carries no psychological burden at all. → All modalities in one stop: it aggregates 100+ official models—use GPT Image for image generation, Seedance for video, and switch to Claude and GPT for copywriting; one Key handles all steps. → Smooth automated pipeline: through the Flatkey CLI tool, you can directly have Claude Code or Codex automatically call models in batches to mass-produce images and generate videos, fully getting the content pipeline running. → Zero-threshold drop-in replacement for developers: fully compatible with the OpenAI interface specification, existing scripts can migrate seamlessly by changing the request address, with 99.5% stability guaranteed. Parameterize the image-generation aesthetics, then drive down the toolchain cost—only then can self-media account growth truly become deterministic, continuous compounding. The several tested blockbuster cases and complete English Prompts for the accompanying images are compiled in the first floor. Which step do you most often get stuck on when generating images now? Welcome to discuss—I will definitely share without reservation. This is a beauty portrait in the racetrack stands generated with GPT Image on Flatkey, with no post-processing retouching or local redrawing at all, straight out of pure Prompt, with zero plastic mask feel; the light and texture are completely the candid quality of a top-tier telephoto broadcast camera position.

全体起立!!开源我的8 维高级独家AI美女人像生图焚决!!(附本人10年人像写真摄影老法师用Fable 5.5 打磨的独家顶级美女人像提示词) 兄弟们有没有想过,为什么你跑出来的 AI 人像总是一股油腻的塑料感和假人味? 因为你还在用空泛的形容词,而没有用真实的摄影物理语言去约束 AI。 分这套沉淀了 8 个维度的AI生图框架心法与批量流水线,能够彻底把 AI 视觉质感拉到顶级水准, 照着这套框架套词,出来的质感直接拉满: 1️⃣ 气质与影调定人设:拒绝空泛的漂亮标签,用具体阶层气质锚定气场,比如 25-year-old East Asian woman, old-money relaxed elegance, editorial fashion portrait。 2️⃣ 面料垂坠替代直白形容:高级感来自物理材质的重量,比如 raw silk, fitted merino knit, subtle collarbone shadow, tailored silhouette。 3️⃣ 抓拍微表情消除死鱼眼:指定瞬间的真实情绪,彻底告别僵硬摆拍,比如 candid moment, soft knowing glance, caught mid-reaction, unaware of the camera。 4️⃣ 电影级光学镜头语言:让画面拥有真实相机的光学景深,比如 85mm portrait lens, f/1.8 shallow depth of field, subtle film grain, natural optical compression。 5️⃣ 方向性光影雕刻皮肤呼吸感:用侧光和轮廓光保留真实毛孔肌理,比如 soft diffuse directional light, gentle rim light, authentic skin texture with visible pores and natural highlights。 6️⃣ 柔和散焦托出主体:环境必须克制且有景深层次,比如 soft morning cafe ambiance, muted warm background bokeh, natural depth。 7️⃣ 克制松弛卡死审美下限:拒绝夸张五官与过度浓妆,追求自然耐看,比如 classy, effortless beauty, understated luxury, natural proportions。 8️⃣ 工业级负面词筑起防火墙:强行拦截各类变形和 CGI 质感,卡死 no plastic skin, no doll face, no extra limbs, no 3D render look, no over-smoothed texture。 有了好提示词,怎么以极低成本批量测试并跑通工作流,才是持续起号的关键。 天天到处开不同工具会员不仅月费极高,频繁切后台更会打碎所有创作节奏。 我自己最近主力在跑的多模态底座是 Flatkey(1 ),对于天天折腾多模态创作和批量做图的人来说,确实是目前极省心也极划算的解法: → 官方模型,更低开销:每天价格比官方直连低至少 20%,最实用的是失败请求按 0 美元计费,多轮调试提示词完全没有心理负担。 → 全模态一站式搞定:聚合了 100 多个官方模型,生图调 GPT Image,做视频用 Seedance,写文案切 Claude 和 GPT,一个 Key 搞定所有环节。 → 自动化流水线丝滑:通过 Flatkey CLI 工具,可以直接让 Claude Code 或 Codex 自动批量调用模型批量产图和生成视频,把内容流水线彻底跑通。 → 开发者零门槛平替:完全兼容 OpenAI 接口规范,现有脚本改个请求地址就能无缝迁移,带 99.5% 稳定性保障。 把生图审美参数化,再把工具链成本打下来,自媒体起号才能真正变成确定性的持续复利。 配图的几组实测大片案例与完整英文 Prompt 整理在一楼,大家现在生图最常卡在哪个环节?欢迎交流,我一定无保留分享。 这是在 Flatkey 用 GPT Image 跑出来的赛道看台美女人像,没有任何后期修图和局部重绘,纯 Prompt 直出,零塑料假面感,光影肌理完全就是顶级长焦转播机位的抓拍质感。

活久见!!谁能想到有一天能看到山姆·奥特曼和达里奥同台给美女伴舞?!🤣 视频prompt和3 个关键 Prompt 避坑参数无保留分享,拿去起号,不要找借口!不爆回来打我!!!

这画面太他喵魔幻了哈哈哈哈: OpenAI 和 Anthropic 的两位死对头掌门人, 居然在同一支 15 秒视频里动作整齐划一地左右伴舞, 而且全程动作丝滑、面部完全没有融化变形!

最绝的是:做这么一条炸裂、多人物高精度互动的 15 秒连贯短视频,在 Flatkey 上调用 Seedance 模型,实际成本居然只要几毛钱(不到 $0.1)!

很多朋友做多人物 AI 视频最头疼的就是: 人一多脸就互换、肢体一动就融化成异形、抽卡几十次成本直接上天。

分享我这次跑通这支「多人物同框舞蹈」视频的 3 个关键 Prompt 避坑参数:

1️⃣ 空间坐标与人物特征强绑定(防换脸关键): 千万不要笼统写“三个人在跳舞”,必须用绝对方位锁死特征:Center: a stunning glamorous woman in black chic dress; Left: Sam Altman with recognizable features in a classic grey tech sweater; Right: Dario Amodei with glasses in casual blazer. 方位定死,模型才不会把两人的脸混在一起。

2️⃣ 动作节拍与视线动态同步(防肢体融化): 指定统一的编舞节奏,比如 synchronized rhythmic backup dance movements, mirrored dynamic footwork, fluid torso groove, natural motion physics,让两边的伴舞动作跟主舞形成物理律动呼应。

3️⃣ 电影级纵深与焦段控制: 用 35mm wide cinematic studio shot, medium full shot, warm studio key lighting 把三个人物收在同一焦平面内,加上 no face morphing, consistent individual identity throughout 15 seconds 强制约束。

这整条视频全程是在 Flatkey(@Flatkey_AI )用 Seedance 跑出来的。有了这种神仙底座,平时无论做正经商业视频还是脑洞整活,体验都太爽了:

🔹 官方模型,更好价格:不拼低质廉价噱头,而是以极具性价比的价格提供官方原厂模型品质。日常使用天天比官方定价至少低 20%,生成 15 秒视频成本直接打到几毛钱。 🔹 疯狂试错零负担:整活和创意最怕抽卡烧钱,Flatkey 的「失败请求费用为 $0」,哪怕动作偶有跑偏也不扣一分钱,随便你放飞脑洞。 🔹 多模态一站式打通:接入 100+ 官方模型,一个 API Key 搞定文本、图片和视频;还能通过 Flatkey CLI 配合 Agent 实现自动化批量出片,一张账单搞定全部流。

把多人物同框的门槛和算力成本打穿之后,AI 视频的上限真的只剩你的脑洞了
