建立 Seedance 影片
在 CometAPI 上建立 Seedance 影片任務。使用文字 Prompt 或參考圖片,選擇時長,並要求精確的 WxH 輸出尺寸。
WxH 欄位選擇一個已記錄的 size 值。支援的模型 ID
請為model 欄位使用以下其中一個確切值。
使用參考圖片
Seedance 2.0、Seedance 2.0 Fast 和 Seedance 2.0 Mini 可接受input_reference。針對支援進階多參考 Prompt 的路由,請依上傳順序重複使用相同的 multipart 欄位。
支援此功能時,請依上傳順序重複使用相同的 multipart 欄位。
一個使用單一 input_reference 的 Mini 生產請求已於
720x1280。該檢查確認請求已完成,但未能將參考圖片的視覺效果與 Prompt 區分開來。
參考圖片的視覺效果與 Prompt 區分開來。
Seedance 2.0 對 Prompt 如何將每張參考圖片與場景連結起來很敏感。請依順序提及上傳的檔案,例如 [Image 1]、[Image 2] 和 [Image 3],然後為每張圖片指定明確的角色:
- 將
[Image 1]用於主要主體、角色或產品。 - 將
[Image 2]用於次要主體、道具或陪襯。 - 將
[Image 3]用於背景、場景、光線或風格。
依模型分類的時長
若省略seconds,CometAPI 會請求一段長度為 5 秒的片段。如需指定特定時長,請將 seconds 以
字串形式傳送。
依模型支援的尺寸
下表集中列出確切的WxH 值。Seedance 2.0 Fast
僅使用第五欄中的 480p 和 720p 值。該欄中的 1080p 值
適用於 Seedance 1.5 Pro 與標準 Seedance 2.0。4K
值僅適用於標準 Seedance 2.0。在 Mini 欄中,— 表示該
解析度不受支援。
WxH 值。確切的 WxH 支援仍取決於模型,因此在依賴未記載的尺寸前,請檢查已完成的媒體。授權

主體
Text prompt that describes the video. Required. When using reference images, describe what each uploaded image should control, such as the subject from [Image 1], the secondary object from [Image 2], and the background or style from [Image 3]. Also state the action, camera motion, visual style, and scene.
"A slow cinematic camera push across a coastal landscape at sunrise."
Seedance model ID. Use one of the exact values below. Aliases such as seedance-mini are not accepted.
doubao-seedance-2-0, doubao-seedance-2-0-fast, doubao-seedance-2-0-mini, doubao-seedance-1-5-pro, doubao-seedance-1-0-pro "doubao-seedance-2-0-mini"
Video duration in seconds. Seedance 2.0, Seedance 2.0 Fast, and Seedance 2.0 Mini accept 4 to 15. Seedance 1.5 Pro accepts 4 to 12, and Seedance 1.0 Pro accepts 2 to 10. The default is 5.
2 <= x <= 155
Output size as an exact WxH value. For Seedance 2.0 Mini, use 864x496, 752x560, 640x640, 560x752, 496x864, or 992x432 for 480p; use 1280x720, 1112x834, 960x960, 834x1112, 720x1280, or 1470x630 for 720p. Mini does not support 1080p or 4K. A Mini request for 1920x1080 produced 1280x720 in one production check. The standard Seedance 2.0 model also accepts its documented 4K values.

Optional reference image uploaded as a multipart file. Seedance 2.0, Seedance 2.0 Fast, and Seedance 2.0 Mini accept this field. On routes that support multiple reference images, repeat the field and reference the files in upload order as [Image 1], [Image 2], and so on. Seedance 1.0 Pro and 1.5 Pro do not accept it.
