The LTX-2: Text to Video workflow is designed to transform text prompts into high-quality videos using the Lightricks LTX-2 model. This workflow leverages the LtxvApiTextToVideo node to interpret text inputs and generate synchronized video and audio outputs. The workflow supports resolutions up to 4K at 50fps, making it suitable for a variety of production needs, from quick social media clips to professional-grade video content. Users can choose between Fast, Pro, and Ultra modes to balance between speed and quality, depending on their specific requirements.
Technically, the workflow utilizes the LtxvApiTextToVideo node to connect with the Lightricks API, which processes the text input to create video content. The SaveVideo node is then used to store the generated video file locally. Additionally, the MarkdownNote node provides documentation and notes within the workflow, ensuring that users have access to important information and links, such as API node details and pricing. This workflow is particularly useful for content creators, marketers, and educators who need to produce video content quickly and efficiently from text descriptions.
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）。
