How do I choose the shape and make sure the button appears?

Describe the shape directly in the prompt within the First Frame group (e.g., “a matte white capsule with a small black button on top, on a wooden table”). The GeminiNode/GeminiNanoBanana2V2 block uses this text to render the prop. Use terms like cube, sphere, capsule, or a custom shape description.

What’s the difference between Seedance 2.0 and 1.5 here?

Both take your first and last frames and synthesize in-betweens. The Seedance 2.0 group (ByteDance2FirstLastFrameNode) generally produces higher-quality motion and detail, while the Seedance 1.5 Version (ByteDanceFirstLastFrameNode) is faster and more budget-friendly. Start with 2.0 for hero shots and 1.5 for quick iterations.

How do I keep the style and environment consistent between frames?

Use the same subject reference(s) for both steps, avoid changing the scene description between the First Frame and Last Frame groups, and keep camera and lighting phrasing stable. If available, reuse the same seed. The workflow is designed to preserve palette and scene continuity from your inputs.

Can I use a custom shape that isn’t a cube, sphere, or capsule?

Yes. Describe the custom shape clearly in your prompt (e.g., “low-profile hexagonal puck”) and include material and color cues. If you have a specific silhouette image, load it via LoadImage as a guiding reference where the workflow allows.

一键变形动画 - ComfyUI 工作流

一键变形动画是一个引导式ComfyUI流程，将简单的桌面道具一键变为你的主体，并生成变形动画。你只需提供一张或多张人物、角色或产品参考图，工作流会根据你的描述和参考图，生成色彩匹配的首帧（如立方体、球体、胶囊或自定义形状带按钮放在桌面上），再生成风格一致的末帧（主体出现在同一场景中），实现无缝变形。底层，首帧和末帧分组使用GeminiNode/GeminiNanoBanana2V2堆栈根据提示和参考渲染图片，SaveImage保存输出，ImageConcanate可并排对比帧。

动画部分，Seedance 2.0分组用ByteDance2FirstLastFrameNode合成高保真中间帧，Seedance 1.5分组用ByteDanceFirstLastFrameNode实现更快更经济的变形。LoadImage导入参考图和生成帧，SaveVideo导出最终视频。由于首末帧都基于主体色板和场景描述，环境、光照和风格从头到尾保持一致，实现“按下按钮”变形动画，操作简单，效果自然。

使用 Comfy SDK 从 TypeScript 或 Python 运行。相同代码可用于 Comfy Cloud 或你自托管的 ComfyUI——只需更改基础 URL。

// Install (beta)
npm i @comfyorg/sdk

// Run this workflow (TypeScript)
import { Comfy } from "@comfyorg/sdk";

const client = new Comfy({ apiKey: "comfyui-..." });
const wf = await client.workflows.fromFile("workflow_api.json");
const job = await client.run(wf);
await job.getOutputs("<output-node-id>")[0].toFile("output.png");

SDK 需要 API 格式的工作流：在 ComfyUI 中打开此工作流，使用文件 → 导出工作流（API）。
