Seedance ComfyUI Workflow Guide

Seedance ComfyUI: the quick answer

Seedance 2.0 is available in ComfyUI as an official Partner Node. ComfyUI provides the node graph and orchestration, while the closed model runs through a hosted service. Running the interface on your computer does not turn Seedance into a local, offline model, and local GPU memory is not the main requirement for the hosted generation step.

Use a current ComfyUI build, sign in to a Comfy account, confirm a positive Partner Node credit balance, and load an official workflow template. Do not start by cloning an unofficialcomfyui-seedance repository.

Choose the right official workflow

Text-to-video (T2V)

Choose T2V when the prompt is your only input. Describe one subject, setting, visible action, camera movement, lighting, and ending state. It is the simplest workflow for validating account access and prompt direction.

Open the official Seedance 2.0 T2V template.

Reference-to-video (R2V)

Choose R2V when images, video, or audio should guide appearance, movement, timing, or rhythm. State what each reference controls and what must remain stable; references do not replace clear instructions.

Open the official Seedance 2.0 R2V template.

First-last-frame-to-video (FLF2V)

Choose FLF2V when the opening and ending compositions are already known. Use compatible frames, then explain how the subject and camera move between them. This works well for product reveals, transformations, and storyboard transitions.

Open the official Seedance 2.0 FLF2V template.

How to run a Seedance workflow in ComfyUI

1. Update ComfyUI. A missing node or template can mean your Desktop, Portable, or self-hosted build is behind the current Partner Node release.
2. Sign in and check credits. Partner Nodes call hosted models, so they require account access and credits.
3. Load an official template. Search the Template Library for Seedance 2.0 or open one of the official JSON files above.
4. Replace inputs deliberately. For R2V, explain the job of every reference. For FLF2V, use frames with compatible subject scale and scene geometry.
5. Validate a small task. Start with one action and one camera instruction. Add complex continuity, audio, or more references only after the basic graph works.

A prompt structure for node workflows

SUBJECT: Stable identity and appearance details.
SETTING: Location, time, weather, and important objects.
ACTION: Opening state, visible action, and ending state.
CAMERA: Shot size, angle, movement, speed, and direction.
LIGHT AND LOOK: Lighting, palette, texture, and mood.
AUDIO: Dialogue, ambience, effects, or music when relevant.
CONTINUITY: Details that must not change.
AVOID: Specific failures such as duplicates or camera jumps.

For reusable examples, open the Seedance 2.0 prompt library and adapt only the parts relevant to your workflow.

Local ComfyUI versus hosted Seedance

• The graph editor, local nodes, file handling, and open models can run on your computer.
• The official Seedance Partner Node sends its generation request to a hosted service.
• Partner Node usage requires account authentication, credits, and a supported network environment.
• Other local preprocessing or compositing nodes may still use your GPU before or after the Seedance node.

Troubleshooting

The Seedance node is missing

Update and restart ComfyUI, then check the official templates. A stable Desktop release can receive new Partner Nodes later than a nightly build.

The workflow loads with unknown nodes

Confirm the JSON came from the Comfy-Org workflow-template repository and review the startup log for failed node imports.

ComfyUI keeps asking you to sign in

For a local installation, open the interface through127.0.0.1 or localhost. A LAN address or unsupported host can prevent normal Partner Node authentication.

The result ignores a reference

Give each reference one clear responsibility and write the non-negotiable continuity details in the prompt. Remove conflicting references and add them back one at a time.

Official sources and next step

This guide was checked against the official Seedance 2.0 Partner Node documentation and the Comfy-Org workflow-template repository. Node names and authentication rules can change, so recheck those sources when the interface differs.

If you want to test the prompt before building a node graph, use the Movalune AI video generator. Movalune is an independent product and is not the official ComfyUI or ByteDance website.
