seedance-2.0 API
透過 Modelflare 非同步視訊路由使用準確的 seedance-2.0 模型 ID。
使用準確的型號 ID seedance-2.0。模型欄位必須與此頁面完全相符。
參數: duration=5resolution=1080pratio=16:9
提示詞: One continuous take, no cuts. An empty indoor swimming pool at night, tiled walls and underwater lights. A swimmer in a chrome-finish suit stands on the edge and lifts both arms; the water answers by leaving the pool, rising as a single rotating column of turquoise that twists up past the roof beams and holds there, the emptied tiles glowing underneath. The camera starts low at the pool edge, cranes up alongside the column and tilts to look down into the drained basin. One hard cyan key from the underwater lights, warm sodium spill from the high windows. Real weight and inertia, spray and refraction, no text.

Section titled “身份驗證與端點”將 Modelflare API 金鑰與 https://modelflare.dev/v1 結合使用。網關入口點是POST /v1/videos。
Authorization: Bearer YOUR_MODELFLARE_API_KEYcurl https://modelflare.dev/v1/videos \ -H "Authorization: Bearer YOUR_MODELFLARE_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "model": "seedance-2.0", "content": [{"type": "text", "text": "A white cat runs through a neon-lit street in the rain, cinematic tracking shot"}], "resolution": "720p", "duration": 5, "generate_audio": false }'儲存任務ID。輪詢 GET /v1/videos/{task_id} 並使用 GET /v1/videos/{task_id}/content 下載。結果 URL 可能會過期,因此請立即傳輸檔案。
curl https://modelflare.dev/v1/videos/TASK_ID \ -H "Authorization: Bearer YOUR_MODELFLARE_API_KEY"Seedance 將 content[] 用於文字、框架和參考媒體;單獨的Seedance資產管理合約是獨立記錄的。
Seedance 使用一個非同步多模態包絡。將文字和媒體放入content[];媒體角色選擇第一幀/最後一幀或參考工作流程。

輸入與輸出限制
Section titled “輸入與輸出限制”此型號支援 480p、720p、1080p 和 4k 輸出,持續時間為 4-15 秒。多模式參考最多允許九張影像、三個視訊和三個音訊剪輯;音訊不能單獨使用。在content[]中以role值標記媒體;第一幀、編輯、擴充和網路搜尋工作流程都有自己的限制。虛擬人像圖片必須先上傳至素材庫;Modelflare 不提供真人認證。
記錄的工作流程範例
Section titled “記錄的工作流程範例”Seedance 2.0 系列支援文字到影片、第一幀/第一幀和最後一幀、多模式引用、編輯、擴展和文字到影片的網路搜尋。將媒體排序為文字、圖像、視頻,然後是音頻。
