promptstringThe text prompt used to generate the videoresolutionenumVideo resolution - 480p for faster generation, 720p for balance, 1080p for high quality, 4k for highest quality. (480p, 720p, 1080p, 4k)durationenumDuration of the video in seconds. Supports 4 to 15 seconds, or auto to let the model decide based on the prompt. (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)aspect_ratioenumThe aspect ratio of the generated video. Use 16:9 for landscape, 9:16 for portrait/vertical, 1:1 for square, 21:9 for ultrawide cinematic, or auto to let the model decide. (auto, 21:9, 16:9, 4:3, 1:1, 3:4, 9:16)generate_audiobooleanWhether to generate synchronized audio for the video, including sound effects, ambient sounds, and lip-synced speech. The cost of video generation is the same regardless of whether audio is generated or not.bitrate_modeenumOutput bitrate mode. 'high' requests a higher-quality, larger-file encode from the model; 'standard' uses the default bitrate. (standard, high)end_user_idvalueThe unique user ID of the end user.What Seedance 2.0 API adds to your video workflow
The page follows the same API-first structure as the reference: test the model, understand the fields, then move into integration.
Multimodal references
Combine prompts with images, videos, and audio so the model can follow subject identity, motion, rhythm, and visual style.
Multi-shot consistency
Create short cinematic sequences with steadier characters, camera logic, and scene continuity across cuts.
Reference-driven motion
Use source clips to guide camera movement, action timing, transitions, and high-impact visual pacing.
Audio-aware creation
Upload audio references or enable generated audio for beat-matched clips, music videos, and synced storytelling.
From playground test to production request
A compact integration path for teams that want to validate output quality before wiring the API into an app.
1. Prepare request
Choose Seedance 2.0 or Seedance 2.0 Fast, then add prompt text and any reference media your workflow needs.
2. Submit generation
Call the API with your account key, model id, duration, resolution, aspect ratio, and media URLs.
3. Poll and render
Track the task until it succeeds, then retrieve the generated video URL for your app, campaign, or pipeline.
What you can create with Seedance 2.0 API
Use the API when your product needs repeatable AI video output, not just a one-off playground result.
Built for real API workflows
Account-gated execution
Users sign in, submit jobs, and consume credits through the existing SdanceAI generation flow.
Reference media handling
The studio supports uploaded reference media, direct URLs, previews, and form/API payload editing.
Scalable model choice
Switch between standard and fast Seedance 2.0 modes based on quality, cost, and latency needs.
Seedance 2.0 API questions
What is Seedance 2.0 API best for?
It is best for short, cinematic AI video generation where prompt control and reference media matter, including product videos, social clips, motion replication, and multi-shot storytelling.
What is the difference between Seedance 2.0 and Seedance 2.0 Fast?
Seedance 2.0 focuses on higher-quality output and stronger creative control. Seedance 2.0 Fast is optimized for faster iteration and scalable batch workflows.
Can I use images, video, and audio in one request?
Yes. The Seedance 2.0 workflow supports text plus mixed reference inputs, including images, video clips, and audio references.
Where can I test it before integrating?
Use the playground on this page to test prompts, references, resolution, aspect ratio, duration, and API payload behavior before moving into production.
What new features does Seedance 2.0 API introduce?
Seedance 2.0 introduces broader multimodal control with text, image, video, and audio references. It is designed for better motion guidance, stronger scene consistency, and more predictable cinematic output.
How is Seedance 2.0 API different from typical AI video generators?
Many video generators rely mostly on prompt interpretation. Seedance 2.0 is more reference-driven, so it can use source media to guide camera motion, action timing, transitions, subject style, and pacing.
How many references can I upload in a Seedance 2.0 API project?
The workflow supports up to 9 image references, up to 3 video references, and up to 3 audio references. Reference video and audio inputs should stay within the documented duration limits.
Does Seedance 2.0 API support voice guidance and lip-sync generation?
The model workflow supports audio-aware generation. You can use audio references for rhythm and pacing, and enable generated audio where supported by the selected version and request settings.
What video length and duration options are available?
Seedance 2.0 is built for short-form clips, commonly in the 4 to 15 second range. Duration, aspect ratio, and resolution should be selected together to match your target output format.
Can I use Seedance 2.0 API for commercial projects?
This page is configured for commercial-use workflows. For production use, review your account plan, credit balance, model availability, and any applicable content policy requirements.
