Seedance 2.0 Video Generation

Generate videos with synchronized audio using ByteDance's Seedance 2.0 via inference.sh CLI.

Quick Start

Requires inference.sh CLI (belt). Install instructions

belt login

belt app run bytedance/seedance-2-0 --input '{
  "prompt": "a jazz band performing in a dimly lit club",
  "generate_audio": true
}'

Models

Model	App ID	Best For
Seedance 2.0	`bytedance/seedance-2-0`	Best quality, up to 1080p
Seedance 2.0 Fast	`bytedance/seedance-2-0-fast`	Faster generation, up to 720p
Seedance 2.0 Studio	`bytedance/seedance-2-0-studio`	Quality + private asset library for portrait consistency
Seedance 2.0 Studio Fast	`bytedance/seedance-2-0-studio-fast`	Fast + private asset library for portrait consistency

All models support text-to-video, image-to-video, multimodal reference-to-video, and synchronized audio generation. Studio variants automatically upload reference images to the BytePlus private virtual portrait library for enhanced character consistency - particularly useful for faces and branded characters.

Modes

The model determines the generation mode from your inputs. These modes are mutually exclusive - use either first-frame/last-frame OR reference inputs, not both.

Mode	Inputs	Description
Text-to-Video	`prompt` only	Generate video from text description
Image-to-Video	`prompt` + `image`	Animate a still image (first frame)
First+Last Frame	`prompt` + `image` + `end_image`	Control start and end frames
Multimodal Reference	`prompt` + `reference_images`/`reference_videos`/`reference_audios`	Guide generation with reference material

Examples

Text-to-Video with Audio

belt app run bytedance/seedance-2-0 --input '{
  "prompt": "ocean waves crashing on rocks during a storm, dramatic cinematic shot",
  "generate_audio": true,
  "duration": 10,
  "ratio": "16:9"
}'

Fast Mode (Cheaper)

belt app run bytedance/seedance-2-0-fast --input '{
  "prompt": "a butterfly landing on a flower in slow motion",
  "generate_audio": true
}'

Image-to-Video

Animate a still image into a video:

belt app run bytedance/seedance-2-0 --input '{
  "image": "https://your-image.jpg",
  "prompt": "gentle camera movement, leaves rustling in the wind",
  "generate_audio": true
}'

Image-to-Video with Start and End Frames

belt app run bytedance/seedance-2-0 --input '{
  "image": "https://start-frame.jpg",
  "end_image": "https://end-frame.jpg",
  "prompt": "smooth transition between scenes",
  "generate_audio": true
}'

Multi-Image Reference

Use multiple reference images to guide character appearance, outfits, and scene elements:

belt app run bytedance/seedance-2-0 --input '{
  "prompt": "The girl from Image 1 wearing the outfit from Image 2 walks through the cafe from Image 3",
  "reference_images": [
    "https://character-portrait.jpg",
    "https://outfit-reference.jpg",
    "https://cafe-scene.jpg"
  ],
  "generate_audio": true,
  "duration": 8
}'

Video Editing (Replace Elements)

belt app run bytedance/seedance-2-0 --input '{
  "prompt": "Replace the perfume in Video 1 with the face cream from Image 1, preserving all original motions and camera work",
  "reference_images": ["https://face-cream.jpg"],
  "reference_videos": ["https://original-video.mp4"],
  "generate_audio": true
}'

Video Extension (Stitch Clips)

belt app run bytedance/seedance-2-0 --input '{
  "prompt": "Video 1 transitions smoothly into Video 2, then the camera enters the painting from Video 3",
  "reference_videos": [
    "https://clip1.mp4",
    "https://clip2.mp4",
    "https://clip3.mp4"
  ],
  "generate_audio": true,
  "duration": 8
}'

Reference with Audio

belt app run bytedance/seedance-2-0 --input '{
  "prompt": "The musician from Image 1 performs the song from Audio 1, voice style referenced from Audio 1",
  "reference_images": ["https://musician.jpg"],
  "reference_audios": ["https://music.mp3"],
  "generate_audio": true
}'

Studio Mode (Portrait Consistency)

Studio variants upload images to BytePlus's private asset library for enhanced face/character consistency:

belt app run bytedance/seedance-2-0-studio --input '{
  "prompt": "The person in Image 1 smiles at the camera, golden hour lighting, cinematic",
  "reference_images": ["https://portrait.jpg"],
  "safety_identifier": "user-abc123",
  "generate_audio": true
}'

Product Ad with Multiple References

belt app run bytedance/seedance-2-0 --input '{
  "prompt": "First-person POV product ad. Opening frame is Image 1, hand picks up the product. Camera pushes into close-up showing details. Use the camera movement style from Video 1. Background music from Audio 1.",

  "ratio": "9:16",
  "duration": 11
}'

Prompt Guide

Reference assets in your prompt using type + index: Image 1, Image 2, Video 1, Audio 1. The index is the position within that type in the arrays you provide. Do NOT use asset IDs in prompts.

Multimodal reference formula:

Image reference: "Refer to the [subject] from [Image N] to generate [scene], keeping [subject] consistent"
Video reference: "Refer to the [camera movement/action] from [Video N]"
Audio reference: "[Character] says: [dialogue], voice style referenced from [Audio N]"

Video editing formula:

Add: "At [timing] of [Video N], add [element]"
Remove: "Remove [element] from [Video N], keeping the rest unchanged"
Modify: "Replace [element] in [Video N] with [new element]"

Video extension formula:

Forward: "Generate content after [Video N]: [description]"
Backward: "Extend the opening of [Video N]: [description]"
Stitch: "[Video 1] + [transition] + followed by [Video 2]"
