# 新增动图任务
您可以通过创建MpcClient实例并设置相关参数新建动图任务，动图任务用于将视频转换为动态图。
#### 前提条件
- 已购买对象存储服务，并参考[上传媒体文件](https://support.huaweicloud.com/usermanual-mpc/mpc010002.html)在媒体处理服务同区域（如华北-北京四）上传媒体处理的源视频。
- 已参考[获取云资源授权](https://support.huaweicloud.com/usermanual-mpc/mpc010003.html)，完成媒体处理服务授权。
 
#### 核心代码
1. **创建动图任务** 。
   动图任务需要设置输入视频文件、输出动图路径、动图帧率、动图宽高等参数。
   ```
   //设置输入视频地址和输出路径
   ObsObjInfo input = new ObsObjInfo().withBucket("mpc-east-2").withLocation("region01").withObject("ok.mp4");
   ObsObjInfo output = new ObsObjInfo().withBucket("mpc-east-2").withLocation("region01").withObject("output");
   //创建动图请求
   CreateAnimatedGraphicsTaskRequest req = new CreateAnimatedGraphicsTaskRequest()
           .withBody(new CreateAnimatedGraphicsTaskReq().withInput(input).withOutput(output)
                   .withOutputParam(new AnimatedGraphicsOutputParam()
                           //设置动图格式
                           .withFormat(AnimatedGraphicsOutputParam.FormatEnum.GIF)
                           //设置动图帧率
                           .withFrameRate(15)
                           //设置起始时间，单位毫秒
                           .withStart(0)
                           //设置结束时间，单位毫秒，最大时间间隔60s
                           .withEnd(3_000)));
   // 发起请求
   CreateAnimatedGraphicsTaskResponse rsp = initMpcClient().createAnimatedGraphicsTask(req);
   // 打印结果
   System.out.println("CreateAnimatedGraphicsTaskResponse=" + JsonUtils.toJSON(rsp));
   ```
