# 任務設定 JSONs範例
這些範例中的任務設定代表您可以執行的最簡單有效任務。它們非常適合用來實驗 服務。當您想要執行更複雜的轉碼或建立不同的輸出時，請使用 主控台來設定您的任務，並產生您的 JSON 任務規格。若要這樣做，請在左側**的任務**窗格中的任務**設定**下，選擇**顯示任務 JSON**。
如需以程式設計方式提交任務的詳細資訊，請參閱 *AWS Elemental MediaConvert API 參考*的其中一個簡介主題：
+ [AWS Elemental MediaConvert 開始使用 AWS SDKs或 AWS CLI](https://docs.aws.amazon.com/mediaconvert/latest/apireference/custom-endpoints.html)
+ [AWS Elemental MediaConvert 開始使用 API](https://docs.aws.amazon.com/mediaconvert/latest/apireference/getting-started.html)
**重要**
我們建議您使用 MediaConvert 主控台來產生生產 JSON 任務規格。
您的任務規格必須符合轉碼引擎的驗證。轉碼引擎驗證代表一組設定之間的複雜相依性，以及轉碼設定和輸入檔案屬性之間的相依性。MediaConvert 主控台可做為互動式任務建置器，讓您輕鬆建立有效的任務 JSON 規格。您可以使用[任務範本](using-a-job-template.md)和[輸出預設](using-a-preset-to-specify-a-job-output.md)集快速開始使用。
若要使用這些範例，請以實際值取代以下預留位置值：
+ 角色 ARN
+ s3：//amzn-s3-demo-bucket
+ s3：//amzn-s3-demo-bucket1

## 範例：自動化 ABR
此範例 JSON 任務規格指定 Apple HLS 中的自動化 ABR 堆疊。除了指定自動 ABR 設定之外，還會明確設定這些值：
+ 加速轉碼`Mode`至 `PREFERRED`
+ `rateControlMode` 至 `QVBR`
+ `qualityTuningLevel` 至 `MULTI_PASS_HQ`
如需自動 ABR 設定的相關資訊，請參閱 [自動化 ABR](auto-abr.md)。
