如何调用SubmitMediaProducingJob - 提交剪辑合成作业_智能媒体服务(IMS)-阿里云帮助中心

本文为您介绍如何使用SubmitMediaProducingJob - 提交剪辑合成作业，通过来完成批量个性化混剪。如果您想使用更加智能快捷的方式进行视频混剪，可使用智能一键成片进行创作，详见批量智能一键成片说明。

场景介绍

进入5G时代，越来越多的商家选择短视频平台做营销推广，将广告制作成短视频投放在多个KOL或营销号。由于各大短视频平台有去重机制（防止视频盗用），内容相同的营销视频会被屏蔽处理，这就要求投放在不同账号的视频，在内容、结构上要有差别。

前提条件

您已安装IMS服务端SDK，详情请参见准备工作。

批量个性化混剪

通过Timeline的方式，可以对视频进行更多的调整。
