    "about": "Seedance 2.0 Fast 是另行命名的 Fast 設定檔，使用 doubao-seedance-2-0-fast-260128 選取。它支援以文字、圖片、影片和音訊參考進行影片生成、編輯與延長。當場景簡報需要的不只是外觀描述時，就可使用此設定檔：既有媒體也能傳達表演、鏡頭語言和聲音。Fast 名稱用來區分請求身分，並不承諾個別非同步任務會在固定時間內完成。\n\n先確定應由哪個元素定義新鏡頭。單獨使用文字即可描述新場景。圖片可確立角色、產品或構圖；影片可提供動作，或提供要修改或延續的既有序列。文件所列的內容組合包括圖片搭配音訊、影片搭配音訊，以及圖片、影片和音訊一起使用，視覺媒體可搭配選用文字。這些組合並未描述僅使用音訊的獨立請求，因此應將聲音參考與其應引導的視覺來源配對。\n\n在 content 陣列和簡報中都要明確保留參考角色。image_url、video_url 和 audio_url 項目可以分別帶有 reference_image、reference_video 和 reference_audio 角色。請描述哪張圖片提供主體、哪段影片提供攝影機運動或動作，以及哪份音訊提供配樂。產品鏡頭中，圖片可以確立包裝，影片則示範經過物件的運動。請指定預期結尾，讓短序列有實用的結束畫面，而非在動作中途停止。\n\n編輯時請指出來源影片、要做的變更，以及要保留的連續性。若變更背景或光線，仍應清楚指定預期主體與動作。延長影片時，請說明接下來發生的事，以及新動作如何連接至既有場景。參考素材會引導生成；請檢查實際接合處與整段影片的外觀、運動方向和時間安排，而非假設接續片段會保留每個影格層級的細節。\n\n文件所列的 2.0 Fast 範圍為四至十五的整數秒，也可使用 -1 讓模型在該範圍內選擇片長。預設片長為五秒。輸出解析度為 480p 或 720p，預設為 720p，且不支援 1080p。可選擇固定的 16:9、4:3、1:1、3:4、9:16 和 21:9 畫幅，或 adaptive 構圖。Adaptive 構圖依相關提示詞或參考情境調整；首格影像鏡頭依起始圖片，多模態構圖則可讓影片優先於圖片。請讀取回傳任務欄位中的實際片長與比例。\n\n使用 generate_audio 選擇生成影片是否包含同步聲音。文件所列的預設值為 true；false 要求無聲。啟用音訊時，此設定檔會根據提示詞和視覺內容生成人聲、音效或背景音樂，指南並建議以雙引號括住對白。請說明說話者，以及聲音與動作的預期關係。請由熟悉該語言的人聆聽對話，並檢查整段影片的聲畫對齊，包括任何編輯或延長的片段。\n\n2.0 Fast 指南排除了舊有 frames 和 camera_fixed 控制，也不支援 flex 離線處理。請在場景中描述攝影機行為，並使用 duration 指定片長。文件仍列有種子和水印選項。相同種子並不保證完全一致的輸出，因此比較修改版本時應保留完成素材，而非只依賴請求設定。\n\n影片詞元用量的計算方式為（輸入影片片長 + 輸出影片片長）× 輸出寬度 × 輸出高度 × 輸出影格速率 / 1024。有輸入影片和沒有輸入影片的請求屬於不同計費類別。任務查詢會回報 usage.completion_tokens 和 usage.total_tokens；請將這些回報數量與完成影片一併保留。\n\n提交會在完成影片可用之前回傳任務識別碼。請追蹤處理狀態，成功後取得 content.video_url，並將回報的片長、解析度、比例、影格速率和用量與結果一併保留。到期間隔從任務建立時間起算，預設為 172800 秒，範圍為 3600 至 259200 秒。請將完成影片、參考素材和提示詞一併儲存，再檢查整段序列中的主體身分特徵、物件接觸、攝影機連續性和聲音時間安排。",
