關於 Ltx 2.3
接收影片(`video_url`),透過重新置中畫面並為新區域生成內容,將其轉換為其他長寬比,而非裁切。`aspect_ratio` 可設為 1:1、4:5、5:4、9:16 或 16:9。`resolution` 為 720p 或 1080p,會與長寬比共同決定輸出尺寸。
參數
請傳送標準名稱或原生名稱其中之一,不要同時傳送兩者。 標準名稱

預設值允許值
說明
video_url必填
video
類型url · video
用於重新構圖的來源影片,透過公開可存取的 URL 或 base64 資料 URI 提供,最長 60 秒。重新構圖會重新裁切影片以符合目標長寬比,並生成與原始內容一致的內容來填補新顯露區域。
aspect_ratio選填
類型enum
預設值16:9
1:14:55:49:1616:9
重新構圖影片的目標長寬比。
resolution選填
類型enum
預設值1080p
720p1080p
輸出解析度級別,會與長寬比共同決定最終尺寸。
enable_safety_checker選填
類型boolean
預設值true
在呼叫端獲得授權的情況下,將此值設為 false 可放寬審核。
必填
標準名稱,也可使用
