The Seedance 1.5 Pro: FLF2V workflow is a powerful tool for creating seamless video transitions between two images. By leveraging the ByteDance and Seedance models, this workflow automatically generates a smooth transition video with synchronized audio, making it ideal for content creators who need to produce polished video content quickly. The core of the workflow involves the ByteDanceFirstLastFrameNode, which intelligently interpolates frames between the provided start and end images, ensuring a fluid motion that mimics natural video footage. This is coupled with audio synchronization features that align the visual transitions with corresponding sound elements, enhancing the overall viewing experience.
Technically, the workflow begins by loading the start and end frames using the LoadImage node. It then processes these images through the ByteDanceFirstLastFrameNode, which applies advanced interpolation techniques to generate intermediate frames. Finally, the SaveVideo node compiles these frames into a coherent video file, complete with synchronized audio. This process not only saves time but also ensures high-quality output, making it a valuable tool for video editors and digital marketers who require quick turnaround times without sacrificing quality.
API
從程式碼使用此工作流
每個 Comfy 工作流都是一個 JSON 圖。下方的 payload 就是此工作流，與 ComfyUI 執行時完全相同 — 你可以從此 URL 取得、放入版本控制，或在 ComfyUI 載入並逐節點執行。
使用 Comfy SDK 以 TypeScript 或 Python 執行。相同程式碼可用於 Comfy Cloud 或你自架的 ComfyUI — 只需更改 base 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 需使用 API 格式的工作流：請在 ComfyUI 開啟此工作流，並使用 檔案 → 匯出工作流（API）。
