How do I control multiple shots and camera moves in one prompt?

Include clear structure in the prompt. Use markers like "Shot 1:", "CUT TO:", or time cues (e.g., "0–5s:") and add camera directives (dolly in, crane up, pan left, 35mm lens, low-angle). Seedance 2.5 parses these cues to inform pacing and composition.

Does the workflow generate audio?

When the ByteDance2TextToVideoNode’s audio option is available and enabled, the API can return a video with synchronized music/effects. If disabled or unsupported in your region/plan, the output will be a silent MP4.

What parameters most affect quality and coherence?

Strong, specific prompts with clear shot structure, a fixed seed for iteration, and a supported resolution/aspect ratio generally yield the most consistent results. If the node offers guidance or strength controls, moderate values often balance detail against motion stability.

Why can’t I render longer than ~30 seconds?

Duration limits are enforced by the Seedance 2.5 API. Set the ByteDance2TextToVideoNode duration within the allowed range. For longer edits, generate multiple clips (e.g., per scene) and stitch them in an editor.

Seedance 2.5: Text to Video - ComfyUI Workflow

Seedance 2.5: Text to Video is a compact ComfyUI workflow that turns a single, well-structured prompt into a cinematic video. At its core is the ByteDance2TextToVideoNode, which connects to the Seedance 2.5 text-to-video service to render up to 30 seconds of footage from natural language. The node accepts your prompt, duration, resolution, and seed, then returns a ready-to-save video (and, when enabled, an audio track with synchronized music and effects). The SaveVideo node captures the result and writes an MP4 to your output directory for easy preview and sharing.

Technically, the ByteDance2TextToVideoNode handles all model-side sampling, motion synthesis, and timing based on your input prompt and parameters. You can embed camera instructions (for example: dolly in, slow pan left, low-angle, 35mm lens) and multi-shot storytelling cues directly in the text (for example: Shot 1 … CUT TO: Shot 2 …). This gives you precise control over pacing and composition without hand-directing keyframes. SaveVideo finalizes the render with your chosen filename pattern and frame rate, making the workflow ideal for brand films, episodic beats, product hero shots, and any scenario where quality and control matter more than budget.

API

Use this workflow from code

Every Comfy workflow is a JSON graph. The payload below is this workflow, exactly as ComfyUI runs it — fetch it from the URL, keep it in version control, or load it in ComfyUI and run it node by node.

Fetching workflow JSON…

Run it from TypeScript or Python with the Comfy SDK. The same code targets Comfy Cloud or a ComfyUI you host yourself — only the base URL changes.

// 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");

The SDK takes a workflow in API format: open this workflow in ComfyUI and use File → Export Workflow (API).

Comfy Cloud API access requires a plan with an API key.
