产品详情
我的收藏

视频点播云剪辑提供专业的在线视频剪辑能力，支持音视频、文字等素材剪辑合成新的视频。本文提供了Java SDK视频剪辑相关的API调用示例，包含创建及管理云剪辑工程、发起剪辑合成任务等。

接口调用说明

  • 本文提供的接口调用示例均通过AccessKey初始化客户端实例。

  • 接口的参数解释和返回字段的详细说明请访问阿里云OpenAPI门户，在各接口右侧的文档页签查看。

  • 本文仅提供部分复杂接口的代码示例，其余接口的SDK代码示例，可以通过阿里云OpenAPI门户获取。访问阿里云OpenAPI门户，在接口的左侧参数配置页签，填写需要的参数信息并发起调用后，在右侧的SDK示例页签，选择SDK版本，选择目标语言，查看并下载示例代码。

  • 本文均以V1.0版本的SDK为例进行接口调用，如需获取V2.0版本的SDK示例，请在通过阿里云OpenAPI门户获取SDK示例时，指定到对应的SDK版本。image.png

初始化客户端

使用前请先初始化客户端，请参见初始化。

通过时间线-发起剪辑合成

调用ProduceEditingProjectVideo接口，完成通过时间线-发起剪辑合成功能。

绝大多数场景下，使用这种方式即可合成视频。

阿里云OpenAPI门户地址：ProduceEditingProjectVideo。

调用示例如下：

说明

通过时间线实现剪辑合成的更多Timeline示例请参见视频剪辑-使用示例。
