# 作业设置示例 JSONs
这些示例中的任务设置表示您可以运行的最简单的有效任务。它们非常适合尝试该服务。如果您想要执行更复杂的转码或创建不同的输出，请使用控制台设置任务并生成 JSON 任务规范。若要执行此操作，在左侧的 **作业** 窗格中的 **作业设置** 下，选择 **显示作业 JSON**。
有关以编程方式提交作业的更多信息，请参阅《*AWS Elemental MediaConvert API 参考*》的介绍性主题之一：
+ [开始 AWS Elemental MediaConvert 使用 AWS SDKs 或 AWS CLI](https://docs.aws.amazon.com/mediaconvert/latest/apireference/custom-endpoints.html)
+ [开始 AWS Elemental MediaConvert 使用 API](https://docs.aws.amazon.com/mediaconvert/latest/apireference/getting-started.html)
**重要**
我们建议您使用 MediaConvert 控制台生成生产 JSON 作业规范。
您的任务规格必须符合转码引擎的验证。转码引擎验证表示设置组之间的复杂依赖关系以及转码设置和输入文件属性之间的依赖关系。 MediaConvert 控制台充当交互式作业生成器，可轻松创建有效的作业 JSON 规范。您可以使用[作业模板](using-a-job-template.md)和[输出预设](using-a-preset-to-specify-a-job-output.md)快速入门。
要使用以下示例，请将以下占位符值替换为实际值：
+ 角色 ARN
+ s3://amzn-s3-demo-bucket
+ s3://amzn-s3-demo-bucket1

## 示例：自动化 ABR
此示例 JSON 任务规范指定了 Apple HLS 中的自动化 ABR 堆栈。除了指定自动化 ABR 设置外，它还会显式设置以下值：
+ 加速转码 `Mode` 到 `PREFERRED`
+ `rateControlMode` 到 `QVBR`
+ `qualityTuningLevel` 到 `MULTI_PASS_HQ`
有关自动化 ABR 设置的信息，请参阅 [自动化 ABR](auto-abr.md)。
