本文為您介紹如何使用SubmitMediaProducingJob - 提交剪輯合成作業，通過來完成批量個性化混剪。如果您想使用更加智能快捷的方式進行視頻混剪，可使用智能一鍵成片進行創作，詳見批量智能一鍵成片說明。

場景介紹

進入5G時代，越來越多的商家選擇短視頻平臺做營銷推廣，將廣告制作成短視頻投放在多個KOL或營銷號。由于各大短視頻平臺有去重機制（防止視頻盜用），內容相同的營銷視頻會被屏蔽處理，這就要求投放在不同賬號的視頻，在內容、結構上要有差別。

前提條件

您已安裝IMS服務端SDK，詳情請參見準備工作。

批量個性化混剪

通過Timeline的方式，可以對視頻進行更多的調整。
