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
通过代码使用此工作流
每个 Comfy 工作流都是一个 JSON 图。下面的内容就是此工作流的完整数据，ComfyUI 运行时也是如此——你可以从该 URL 获取、放入版本控制，或在 ComfyUI 中加载并逐节点运行。
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）。
