🚀 Why Use Seedance 2.5 API?

Seedance 2.5 is ByteDance's most advanced video generation model, offering unparalleled video quality and motion consistency.

Cinematic Quality: Generate up to native 4K AI videos with realistic physics and lighting.
Realistic Human Faces: Best-in-class facial fidelity — natural expressions, skin detail, and identity consistency across frames.
Less Censorship: More permissive content policy compared to other AI video models, enabling a wider range of creative use cases.
Superior Motion Control: Advanced camera movement and character consistency for professional results.
Multimodal API: Supports Text-to-Video (T2V), Image-to-Video (I2V), and Video Extension.
Developer-First: Fast processing via the MuAPI infrastructure with a simple Python SDK.

🌟 Key Features of Seedance 2.5 API

✅ Realistic Human Face Generation: Produces natural, high-fidelity human faces with accurate expressions, skin texture, and identity consistency — no uncanny valley.
✅ Seedance 2.5 Text-to-Video (T2V): Transform complex descriptive prompts into stunning AI video clips.
✅ Seedance 2.5 Image-to-Video (I2V): Animate any static image with precise motion control using images_list.
✅ Seedance 2.5 Omni-Reference: Condition a video on any combination of image, video, and audio references in one request.
✅ Seedance 2.5 Character: Generate a multi-panel character sheet (front, back, side, action pose, expressions) from 1–3 reference photos. Use @character:<id> inline in any prompt, or pass the sheet directly as an anchor image for tighter face fidelity via consistent_video().
✅ Seedance 2.5 Video-Edit: Edit existing videos using text prompts and reference images for stylized results.
✅ File Upload: Directly upload local images and videos using the upload_file method, supporting seamless use in generation tasks.
✅ High-Resolution Output: Support for basic and high (1080p+) quality settings.
✅ Less Censorship: More permissive content policy than competing models — broader creative freedom out of the box.
✅ Flexible Aspect Ratios: Optimized for 16:9, 9:16 (TikTok/Reels), 4:3, and 3:4.

🛠 Installation

Via Pip (Recommended)

pip install seedance-2-api

From Source

# Clone the Seedance 2.5 API repository
git clone https://github.com/SamurAIGPT/Seedance-2.5-API.git
cd Seedance-2.5-API

# Install required dependencies
pip install -r requirements.txt

Configuration

Create a .env file in the root directory and add your MuAPI API key:

MUAPI_API_KEY=your_muapi_api_key_here

🤖 Seedance 2.5 MCP Server (New!)

You can now use Seedance 2.5 as an MCP (Model Context Protocol) server. This allows AI models (like Claude Desktop or Cursor) to directly invoke Seedance tools.

Running the MCP Server

Ensure MUAPI_API_KEY is set in your environment.
Run the server:
```
python3 mcp_server.py
```

To test with the MCP Inspector:

npx -y @modelcontextprotocol/inspector python3 mcp_server.py

💻 Quick Start with Seedance 2.5 API (Python)

from seedance_api import SeedanceAPI

# Initialize the Seedance 2.5 client
api = SeedanceAPI()

# 1. Generate Video from Text (T2V) using Seedance 2.5 API
print("Generating AI Video using Seedance 2.5...")
submission = api.text_to_video(
    prompt="A cinematic slow-motion shot of a cyberpunk city in the rain, neon lights reflecting on puddles, 8k resolution",
    aspect_ratio="16:9",
    duration=5,
    quality="high"
)

# 2. Wait for completion
result = api.wait_for_completion(submission['request_id'])
print(f"Success! View your Seedance 2.5 video here: {result['url']}")

      "aspect_ratio": "16:9",
      "duration": 5,
      "quality": "basic"
  }'

3. Seedance 2.5 Omni-Reference

Endpoint: POST https://api.muapi.ai/api/v1/seedance-2.0-omni-reference

Condition a single video generation on any combination of image, video, and audio references. Use @character:<id> inline in the prompt to inject a character (see section below).

curl --location --request POST "https://api.muapi.ai/api/v1/seedance-2.0-omni-reference" \
  --header "Content-Type: application/json" \
  --header "x-api-key: YOUR_API_KEY" \
  --data-raw '{
      "prompt": "A dramatic chase scene through a neon city",
      "aspect_ratio": "16:9",
      "duration": 5,
      "images_list": ["https://example.com/scene_ref.jpg"],

  }'

4. Seedance 2.5 Character (Consistent Character Sheets)

Endpoint: POST https://api.muapi.ai/api/v1/seedance-2-character

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

Once the sheet is generated you can use it two ways:

@character:<request_id> inline in any T2V, I2V, or Omni-Reference prompt
Pass outputs[0] (the sheet image URL) directly as @image1 in an I2V request for tighter face fidelity via consistent_video()

Field	Type	Required	Description
`images_list`	array of URLs	Yes	1–3 photos of the reference person
`prompt`	string	Yes	Desired outfit/style for the character

curl --location --request POST "https://api.muapi.ai/api/v1/seedance-2-character" \
  --header "Content-Type: application/json" \
  --header "x-api-key: YOUR_API_KEY" \
  --data-raw '{
      "images_list": ["https://example.com/person.jpg"],
      "prompt": "cyberpunk jacket with neon accents"
  }'

Cost: $0.18 per character sheet

5. Seedance 2.5 Video-Edit

Endpoint: POST https://api.muapi.ai/api/v1/seedance-v2.0-video-edit

curl --location --request POST "https://api.muapi.ai/api/v1/seedance-v2.0-video-edit" \
  --header "Content-Type: application/json" \
  --header "x-api-key: YOUR_API_KEY" \

      "prompt": "The cat walks through a garden",
      "video_urls": ["https://example.com/video.mp4"],
      "images_list": ["https://example.com/image.jpg"],
      "aspect_ratio": "16:9",
      "quality": "basic",
      "remove_watermark": false
  }'

🎭 Character Consistency Workflow

Create a fictional character from reference photos and maintain their identity across multiple video scenes.

See CHARACTER_CONSISTENCY.md for a full guide.

Option A — `@character:<id>` inline (simplest)

from seedance_api import SeedanceAPI
api = SeedanceAPI()

# Step 1 — generate a character sheet (1–3 reference photos)
char = api.create_character(
    images_list=["https://example.com/person.jpg"],
    outfit_description="cyberpunk jacket with neon accents, glowing visor",
)
char_id = char["request_id"]
api.wait_for_completion(char_id)  # wait for sheet to render

# Step 2 — reference the character inline in any prompt
video = api.text_to_video(
    prompt=f"@character:{char_id} rides a motorcycle through a neon-lit city at night",
    aspect_ratio="16:9",
    duration=5,
)
result = api.wait_for_completion(video["request_id"])
print(f"Video: {result['outputs'][0]}")

# Multiple characters in one prompt
char2_id = "another-completed-character-request-id"
video2 = api.text_to_video(
    prompt=f"@character:{char_id} and @character:{char2_id} face off in a neon-lit arena",
    aspect_ratio="16:9",
    duration=5,
)

Option B — `consistent_video()` (tighter face fidelity)

Pass the character sheet directly as the anchor image for Image-to-Video generation.

# Get the sheet URL after character creation
sheet_result = api.wait_for_completion(char_id)
sheet_url = sheet_result["outputs"][0]

# Generate with the sheet as anchor
video = api.consistent_video(
    sheet_url=sheet_url,
    prompt="@image1 draws their weapon in slow motion, dramatic lighting",
    aspect_ratio="16:9",
    duration=5,
    quality="high",
)
result = api.wait_for_completion(video["request_id"])
print(f"Video: {result['outputs'][0]}")

Tip: @character:<id> works in T2V, I2V, and Omni-Reference prompts. Use consistent_video() when face similarity is critical.
