# Seedance-2 Overview

> Summarizes the Seedance 2.0 asset management and video generation APIs.

# Seedance-2

The Seedance 2.0 documentation is divided into two parts in the Apifox structure: **Asset Management** and **Video Generation**.

## Asset Management

First create an asset group, then upload assets and poll until `Active`, and finally reference them in the `content` of a video request using `asset://{assetId}`.

  <Card title="Create Asset Group" icon="folder-plus" href="/en/videos/seedance-2/asset-create-group">
    `POST /v1/seedance/asset/CreateAssetGroup`
  </Card>

  <Card title="Upload Asset" icon="upload" href="/en/videos/seedance-2/asset-create-media">
    `POST /v1/seedance/asset/CreateAsset`
  </Card>

  <Card title="Get Asset" icon="search" href="/en/videos/seedance-2/asset-get">
    `POST /v1/seedance/asset/GetAsset`
  </Card>
</CardGroup>

## Video Generation

<CardGroup cols={2}>
  <Card title="Create Video" icon="clapperboard" href="/en/videos/seedance-2/generation">
    `POST /v1/video/generations`, multimodal `content` + `metadata`.
  </Card>

  <Card title="Query Task" icon="hourglass" href="/en/videos/seedance-2/query">
    `GET /v1/video/generations/{task_id}`
  </Card>
</CardGroup>

## Recommended Call Sequence

1. [Create Asset Group](./asset-create-group) → obtain `GroupId`
2. [Upload Asset](./asset-create-media) → obtain `task_id` / `AssetId`
3. [Get Asset](./asset-get) → confirm `Status=Active`
4. [Create Video](./generation) → obtain `task_id`
5. [Query Task](./query) → get `video_url`
