What is Seedance 2.0?

Seedance 2.0 is ByteDance's latest video generation model, capable of producing high-quality, photorealistic videos from text prompts or reference images. It supports:

• Text-to-Video — generate video from a text description
• Image-to-Video — animate up to 9 reference images with motion guidance
• Omni Reference — combine images, video clips, and audio as multi-modal reference inputs
• Video Extend — seamlessly extend any generated video
• Consistent Character — generate a 4K multi-panel character sheet from reference photos; use @character:<id> inline in any prompt, or wire the sheet image directly into Consistent Character Video for tighter face fidelity

Installation

Via ComfyUI Manager (recommended)

1. Open ComfyUI Manager → Install via Git URL
2. Paste: https://github.com/Anil-matcha/seedance2-comfyui
3. Restart ComfyUI

Manual

cd ComfyUI/custom_nodes
git clone https://github.com/Anil-matcha/seedance2-comfyui
pip install -r seedance2-comfyui/requirements.txt

Quick Start

1. Sign up at muapi.ai and go to Dashboard → API Keys → Create Key
2. Right-click the ComfyUI canvas → Add Node → 🌱 Seedance 2.0
3. Add a 🔑 Seedance 2.0 API Key node, paste your key, and wire its output to any generation node
4. Write a prompt and hit Queue Prompt

Tip: If you use the MuAPI CLI, run muapi auth configure --api-key YOUR_KEY once and all nodes will pick it up automatically — no need to paste the key anywhere.

Node Reference

🔑 Seedance 2.0 API Key

Set your muapi.ai API key once and wire the output to all generation nodes. Alternatively, leave every api_key field blank — nodes automatically read from ~/.muapi/config.json if you've authenticated via the CLI.

🌱 Seedance 2.0 Text-to-Video

Generate a video from a text description.

Outputs: video_url · first_frame (IMAGE) · request_id

🌱 Seedance 2.0 Image-to-Video

Animate reference images into a video. Connect up to 9 images via image_1 … image_9 and reference them in the prompt using @image1 … @image9.

Example prompt:

The cat in @image1 walks gracefully through a sunlit garden.
@image1 transforms into @image2 with a smooth dissolve transition.

🌱 Seedance 2.0 Omni Reference

Multi-modal video generation that combines images, video clips, and audio clips as reference material alongside a text prompt. Use @image1…@image9, @video1…@video3, and @audio1…@audio3 to reference media in the prompt.

Example prompt:

A person @image1 walking on the beach at sunset, cinematic lighting, with @audio1 as background music.

Outputs: video_url · first_frame (IMAGE) · request_id

🌱 Seedance 2.0 Consistent Character

Generate a 4K / 21:9 multi-panel character sheet (front, back, side profile, action pose, facial expressions, accessories) from 1–3 reference photos of a real person.

Outputs:

Recommended workflow — wire sheet_image into Consistent Character Video:

[LoadImage] ──→ [🌱 Consistent Character] ──(sheet_image)──→ [🌱 Consistent Character Video]
                    [outfit_description]       (sheet_url)          [scene prompt]

Alternative — use @character:<id> in any prompt (simpler but looser face fidelity):

[🌱 Consistent Character] character_id ──→ (paste into prompt) ──→ [🌱 Text-to-Video]

T2V prompt: "@character:{character_id} rides a motorcycle through a neon-lit city at night"

🌱 Seedance 2.0 Consistent Character Video

Generate a video scene with locked character identity. Anchors on the character sheet image as @image1 for maximum face/identity preservation.

Connect sheet_image (or paste sheet_url) from the Consistent Character node.

Outputs: video_url · first_frame (IMAGE) · request_id

Example prompt:

@image1 walks through a rain-soaked neon city, cinematic slow motion

🌱 Seedance 2.0 Extend

Continue any completed Seedance 2.0 video. Connect the request_id output from a generation node.

🌱 Seedance 2.0 Save Video

Downloads the generated video to ComfyUI's output folder and returns all frames as an IMAGE tensor for use with other nodes (preview, VHS, upscale, etc.).

[LoadImage] → [🌱 Consistent Character] → sheet_image → [🌱 Consistent Character Video] → [🌱 Save Video]
               [outfit_description]          ↓               [scene prompt]
                                    [Preview Image]                ↓
                                    (character sheet)      [Preview Image]
                                                           (first frame)
