主路线已经确定:Seedance 2.5。
用户已确认 Seedance;作者使用 SD2.5 缩写。本次执行规格采用官方模型 doubao-seedance-2-5-260628。第一轮直接导入 Xeed 现有花朵作为第一帧,无需先运行 FLUX 或重新生成一株植物。
Seedance 负责首帧到低幅视频。网页负责根系路径、功能文字与真实状态。官方服务支持首尾帧、5 秒任务和本地图片 data URI;完整请求与任务辅助脚本已经写好,但尚未付费调用。模型文档 · 首帧输入说明
本次没有找到公开可下载的 Seedance 2.5 权重,因此不能称它为“最强开源模型”。此轮以根茎稳定、花朵身份保持、循环与网页成本检验实际表现。FLUX / Qwen → Wan 的可下载权重路线保留为后续替代,不是当前流程的前置条件。
植物的细丝要有来处。
视觉骨架是可追踪的 根冠 → 主根 / 茎 → 分支 → 细根 / 叶脉 → 粒子。粒子贴合这个结构,让人看清每条纤维属于哪里。随机漂浮光点可以少量存在,但不能淹没根茎。
结构关系示意图;不是生成植物素材或生物模型。
- 形态固定:每株植物有固定根冠、主要分支数与轮廓,把“同一个体”写入每次动态约束。
- 动作克制:细丝轻摆、光沿根茎传播、稀疏粒子漂移;主根连接稳定。
- 色彩有角色:Lamina 玉绿,Umbra 琥珀,Cirra 冰青,Vesper 象牙;共享线宽、亮度范围与背景。
- 留白清晰:素材承载植物与装饰;标签、记录、按钮、tracking line 由网页渲染。
把当前花朵做成一段可接根的素材。

导入当前第一帧,冻结花朵身份
使用 reference/xeed-organism-candidate.png,保留青色膜状花瓣、黄绿色中心与蓝紫色弯曲茎。当前源 hash 已写入清单。只有确实要修细丝时才运行可选静帧编辑提示词;改过图就重新测接点。
产物:冻结第一帧、source SHA256、尺寸、视觉审查与权利记录。
定义静止连接带,再离线准备请求
整条茎尤其下端连接带保持完全静止;只让花瓣外缘轻动、少量光沿纹理流。seedance-job.py prepare 将本地 PNG 编入官方支持的 data URI,无需公开托管图片。此步骤没有网络。
python3 seedance-job.py prepare \ --image reference/xeed-organism-candidate.png \ --module flower-pilot \ --output work/seedance/request.private.json
产物:私有原始请求体与不含像素的 metadata。请求含图像,不放入网页或 Git。
Seedance 5 秒 I2V,提交一次
真实执行时设置本地 ARK_API_KEY。模型固定,首尾同一图,ratio adaptive;5 秒、720p、无音频、MP4 是首轮选择。下面仅是手工执行示例,本次未调用。
python3 seedance-job.py submit \ --request work/seedance/request.private.json \ --job-dir work/seedance/jobs
官方 POST 返回 id,脚本立即保存。提交前保存请求 hash attempt marker;同一请求已尝试就不重复 POST。超时需先检查服务侧任务,不能自动重发。
产物:实际任务 ID、create 响应、attempt marker、实际参数和费用。
按 ID 轮询,再下载成功结果
GET tasks/{id} 返回 queued / running / cancelled / succeeded / failed / expired。成功地址是 content.video_url。脚本只 GET 轮询,超时可用同一 ID 恢复;不会重新创建任务。
python3 seedance-job.py poll \ --task-id ACTUAL_TASK_ID --job-dir work/seedance/jobs \ --interval 10 --timeout 600 python3 seedance-job.py download \ --task-id ACTUAL_TASK_ID --job-dir work/seedance/jobs \ --output work/seedance/xeed-flower-specimen01-idle-r001-master.mp4
终态失败与未知状态报错。下载不向签名存储地址转发 API Key;检查非空与 MP4 ftyp 签名后才完成改名。结果地址有有效期,及时存母版。
产物:状态快照、母版、实际字节与 SHA256。完整 curl 与来源在 README。
逐帧验下端茎,再验三次循环
五处抽样之外,逐帧看下端接点;3 px / 1254 源尺寸只是首轮容限。超限就重做,或用第一帧固定下端 stem band 与动态花瓣合成,再审边界。不能让网页根线追着错误的漂移掩盖接缝。仍不稳定则使用静态花朵和确定性根线。
产物:tail UV 漂移表、帧条、接缝检查、评分。首尾同图不替代这些检查。
导出 Web MP4 和 poster
使用已有 FFmpeg 检查实际 codec、尺寸和帧率。QA 通过后导出 720 宽、24 fps、无音频 MP4,poster 从冻结首帧导出;具体命令在 README。720 源不放大后宣称细节提高。循环、透明、压缩和浏览器分别验收。
产物:保留的母版、Web MP4、poster、实际 bytes / fps / codec / hash。
填写素材合同,再放入真实页面
填实际模型、任务、费用、源 / 输出哈希、tail drift、许可、loop 与浏览器证据。图像坐标经过真实渲染器投影到 SVG;茎内重叠点为根系原点,沿测得切线接出后再分叉。
产物:manifest、真实页面的连接证据、少动态 poster 与失败回退。
只在第一株通过后扩展
中心花朵保持身份,四个功能由网页根系、文字和颜色强调。后续独立模块素材可使用下面四套备选模板;不要在首轮悄悄换成 fern 或新的分支形态。
产物:可复用制作记录;正式接入与发布仍分别记录。
先做这朵花,再使用备选模板。
当前首轮默认使用 flower-pilot。四模块的独立植物模板供后续风格探索,不替换当前中心花朵。提示词已完成,真实生成效果尚未验证。
Xeed Flower当前中心花朵首轮默认
现有1254静帧直接导入;静帧文字仅用于可选编辑,动态以冻结第一帧为准。
可选静帧编辑
Use the provided Xeed flower image as the identity reference. Preserve the same complete bloom with translucent cyan membrane petals, dense vein-like filaments, the chartreuse luminous center, and its long blue-violet sinuous tapered stem against black. Keep the complete lower stem and distal tip inside the image and preserve their exact placement. Refine only the readability of existing fine veins and small particles; do not redesign the organism. The lower stem exit region must remain a continuous, stable surface so deterministic webpage root lines can attach later. Keep generous empty margin around the lower tip. No new petals, root crown, extra stem, root branches, interface lines, words, numbers, buttons, logo or watermark. This is an optional still-edit specification; importing the existing image unchanged is the baseline.
Seedance 5 秒动态图生视频
Animate the exact provided Xeed flower into a calm five-second ambient clip. Keep the camera locked, composition and scale fixed, and the complete blue-violet sinuous stem and its distal tip completely immobile. The entire lower quarter of the stem is a static attachment band: no translation, rotation, deformation, fading or particle occlusion in that region. Preserve the translucent cyan membrane petals, their dense fine veins, the chartreuse center and the same petal count. Allow only very tiny slow membrane flutter at outer petal edges and a few fine particles travelling along existing petal veins. The stem, tip and background remain unchanged in every frame. End close to the initial petal pose, illumination and particle density. Do not create roots, branches, new petals, another flower, text, interface lines or camera motion. Webpage root paths will be attached to the fixed tip later. Do not visibly shift the attachment junction.
Lamina互动 / 感知完整静帧与动态提示词
视觉任务:微小弯曲;光沿现有根茎传播;主干与根冠稳定。 真正触碰反馈由网页状态决定,不烘在艺术素材中。
静帧 · Still
Create a single original digital botanical specimen for Xeed in a fixed frontal three-quarter studio view. The organism is a compact fernlike plant with a clearly readable upright stem, three primary fronds with fine leaflets, a narrow root crown, and long branching roots. Build its surface from thousands of fine luminous filaments and small discrete particles while preserving a solid connected botanical structure underneath. Every main root visibly joins the same crown; every secondary branch has a parent. Use pale jade green and warm ivory with only a small cyan highlight. Root hairs taper naturally and remain individually readable against an ink-black background. Concentrate light at junctions and let thin fibers carry it outward. Make the silhouette recognizable as a small poster. Show the complete plant and root tips with generous empty margins. Only the specimen and subtle light: no UI, tracking lines to buttons, words, numbers, panels, logo, watermark or other objects. This is designed botanical art, not a measurement. Preserve a calm, precise, tactile character rather than dramatic magical growth.
图生视频 · Motion
Animate the provided approved Xeed Lamina image while keeping the camera, crop, silhouette, stem, root crown, root junctions, frond count and palette fixed. Use tiny, slow flexing of existing leaflets and root hairs; main roots retain their shape. Small light particles travel along existing filaments from the crown toward the fronds with a faint pause at junctions. Motion stays low in amplitude and slow enough for reading nearby interface text. Finish close to the starting pose and brightness. No new growth, new branch, root fusion, disappearance, camera movement, flicker, rapid pulsing, text or interface objects. Keep particles on visible plant paths. This is an ambient loop candidate, not a response to a measured event.
Umbra环境 / 气候完整静帧与动态提示词
视觉任务:固定主体,轻微同向摆动;环境粒子作为装饰层。 雨、温度与生长速率不能伪装成测量。
静帧 · Still
Create one original Xeed environmental botanical specimen in a fixed frontal three-quarter studio view. Show a low spreading plant with a sturdy central stem, a broad grounded root crown, and clearly separated branching roots. Many hair-thin filaments follow roots and stems like a luminous vascular structure, never replacing them with an unconnected particle cloud. Use muted amber and olive gold on the organism with sparse pale cool-blue suspended points behind it. Light must make root continuity, depth and branching readable. Keep the largest roots and main stem stable and defined; roots taper into fine strands. Use an ink-black background, generous margins and complete visible root tips. Suspended points are decorative atmosphere, not a rain gauge or weather chart. Keep the atmosphere thin enough to reveal every root junction. No UI, text, numerical data, scales, panels, logo, watermark or glowing lines connecting to invisible controls. This is designed visual art for an environment module, not evidence of a verified climate effect.
图生视频 · Motion
Animate the approved Xeed Umbra image with a locked camera, constant framing and the same connected stem and root topology throughout. Existing fine fibers make a very slight synchronized lateral sway, returning toward the initial pose; large roots and the crown remain stable. Sparse decorative cool-blue points drift slowly behind the organism without hiding root junctions. Amber light changes gently and uniformly within existing roots, without rapid pulses. End close to the initial posture and illumination. No new leaves, accelerated growth, drought damage, seasons, root melting, camera movement, smoke, text or UI. Environmental measurements and scenario labels will be rendered separately by the webpage.
Cirra动作 / 形态完整静帧与动态提示词
视觉任务:波动从根部沿已有枝叶传到末端;根冠固定。 生成视频不承诺任意时间点可逆或逐帧可控。
静帧 · Still
Create one original Xeed botanical motion specimen, fixed frontal three-quarter view, complete organism in frame. It has two gently arched stems attached to an intact rooted base, delicately branching feathery fronds and many fine root hairs. Its structure must read as a plant: visible rooted base, continuous stems, attached fronds, and parent-child root branches. Use ice cyan and soft periwinkle with an ivory crown accent. Compose fine luminous filaments in restrained flowing curves with very small distinct light particles following existing fibers. The main stems remain defined enough to trace continuously from root to tip. Show generous ink-black negative space and every root tip. The pose suggests gentle flexibility, not a twisted skeleton or jellyfish tentacles. No letters, symbols, UI, timeline, chart, numbers, logo, watermark or external tracking lines. This is designed art for motion exploration; do not embed an animation sequence or unverified biomechanical claims in the still.
图生视频 · Motion
Animate the exact approved Xeed Cirra specimen without changing its identity. Keep camera and framing fixed, both stems anchored to the same crown and all branching junctions visible. Add one small slow travelling flex through existing fronds, from base to tip, with a subtle delay between neighboring fine fibers. Large stems remain anchored and bend slightly. A few cyan points follow existing filaments and fade gently at tips. Return close to the initial pose and light by the end. No new branch, root fusion, tentacle transformation, abrupt snap, large wind, camera rotation, zoom, flicker, text or UI. This is ambient motion; precise pause, scrubbing and event-driven motion remain separate runtime controls.
Vesper观察 / 记录完整静帧与动态提示词
视觉任务:低幅纤维摆动与稀疏粒子流,适合长时间观察。 观察日期、照片与证据关系始终由 HTML 记录层承载。
静帧 · Still
Create one original Xeed botanical observation specimen in a fixed frontal three-quarter studio view. The plant is slender and contemplative, with one continuous main stem, a few clearly separated buds, an exposed root crown and delicate connected fine roots. Every bud is attached; every primary root joins the same crown. Build subtle luminous detail from warm ivory particles and fine pale-gold filaments with a restrained lavender accent. Keep stem, buds and root junctions readable through the surface particles. Center this calm subject with generous ink-black margins for later HTML labels, complete roots and no cropped tips. It should invite sustained observation rather than spectacle. No dates, numbers, text, notebook pages, photographs, panels, symbols, logo, watermark, UI or external links. This is designed botanical art, not documentary growth evidence or a historical photograph. Preserve an original identity consistent across future assets.
图生视频 · Motion
Animate the approved Xeed Vesper still as a quiet ambient specimen. Keep camera, crop, single stem, buds, crown and root connections unchanged. Allow tiny swaying of the finest root hairs and a slow low-amplitude drift of a few ivory particles along existing fibers. Main stem and buds retain position and shape. Light variation stays subtle and never suggests blooming, aging or measured growth. End close to the opening pose, light and particle density. No new bud, new leaf, root fusion, disappearing tips, large luminosity change, camera movement, text, dates, record cards or UI. Observation records and tracking connections will be placed by the webpage.
不生成文字、数字、界面、logo、水印、悬空无源细丝、断根、融化或合并的根、剧烈闪烁、动物化形态、突然增长、镜头移动。工具明确支持 negative prompt 才放入独立字段,否则写进主提示词。
循环与透明背景,分别验收。
循环
原尺寸并列看首尾,检查轮廓、根冠、亮度、粒子密度与方向。连续播放三次。仅轻微粒子不同可测试短交叉淡化;主根错位会产生双根,应改片段或重做。往返播放只适合可逆的轻摆;单向粒子流反播会像倒流。
透明
黑底加 screen 混合不等于 alpha。可在暗色页面试用,但浅色背景、重叠文字与高亮区可能失效。需要跨背景复用时做实际 alpha,并在深、浅、彩色背景分别检查细根和光边。混合模式说明
MP4 在本合同作为不透明兼容版。Seedance MOV 文档描述 H.264 / yuv444p,不能因为 MOV 扩展名就声称透明。WebM VP9 alpha、HEVC alpha 等替代需核实实际编码与目标浏览器播放。第一版可以采用暗底视频和 poster,之后再验证双格式透明版本。官方格式说明
“视频能打开”之外,还要查实际像素格式、alpha、浏览器、边缘、循环接缝与色彩。
每个素材都有网页合同。

让根从茎里接出,再跟随真实功能。
当前源图的实测接点
源图 1254×1254,原点在左上。原手工参考点 stem_overlap=(0.4837903,0.9330144) 保留为诊断点;末端 distal_tip=(0.5133062,0.9601276)。当前 renderer 的实际起点是 renderer_attachment_overlap=(0.473777592,0.921052632),对应源码 STEM.overlap=(594.1171/1254,1155/1254),位置更深入下端茎。cyan 主根在约20–40 CSS像素的重叠带中从透明渐现,实际范围随显示几何变化。这是源码与静态源记录,不是生成视频验证。
切线用 A=(0.4812201,0.9290271)、B=(0.4869437,0.9370016),投影后再求方向。当前主根从实际renderer起点沿这条切线接到tip,再沿1190行末段采样到tip的exit方向延续后分叉;不从旧手工点起画。
img / video:按实际 object-fit 内容矩形,包含 letterbox、裁切和 CSS 变换。LivingSpecimen:按实际 texture / shader 变换与 canvas CSS 几何;当前记录 0.94 texture scale,最终页面仍需校准。不能用素材容器中心或矩形底边代替植物接点。
manifest 已包含 attachment_landmarks、切线样本、源 hash、帧漂移、runtime_placement 和验证状态。新首帧 hash 改变就必须重新测量。
素材负责植物的质感。tracking line 由 SVG / Canvas 读取真实 HTML 锚点,用平滑曲线连接当前入口。页面滚动、缩放、面板展开和手机改布局后,根线仍跟着功能位置。生成素材中的光丝只属于植物本体。
| 层 | 职责 |
|---|---|
| 植物艺术 | 母版、循环视频、poster,稳定形态与低幅氛围。 |
| 根系连接 | 根冠锚点到功能 DOM 锚点;细分支与移动光点使用确定性路径。 |
| 功能强调 | 悬停、键盘焦点或选中时强调对应根线和入口;文字一直可见。 |
| 真实状态 | 模块、保存结果、日期和记录由应用状态提供,反馈跟随实际结果。 |
四个入口共享根冠、线宽与反馈节奏,用模块颜色区分。平时根线轻;选中后主根更清楚,少量光点沿路径流向入口。点击目标保持足够大,手机用更短连接,减少动态效果保留静态线。
Lamina 静帧 → 低幅循环 → poster 回退 → 根冠到真实入口 → 一次选中强调。通过后复制到其余模块。艺术视觉不会自动成为行为或学习证据。
