# Exemples de paramètres de tâche JSONs
Les paramètres des tâches présentés dans ces exemples représentent les tâches valides les plus simples que vous puissiez exécuter. Ils fonctionnent bien pour expérimenter le service. Lorsque vous souhaitez effectuer des transcodages plus complexes ou créer différentes sorties, utilisez la console pour configurer votre tâche et générer votre spécification de tâche JSON. Pour ce faire, dans le volet **Job** de gauche, sous **Paramètres du job**, choisissez **Show job JSON**.
Pour plus d'informations sur la soumission de votre tâche par programmation, consultez l'une des rubriques d'introduction de la référence sur les *AWS Elemental MediaConvert API* :
+ [Commencer à AWS Elemental MediaConvert utiliser le AWS SDKs ou le AWS CLI](https://docs.aws.amazon.com/mediaconvert/latest/apireference/custom-endpoints.html)
+ [Commencer à AWS Elemental MediaConvert utiliser l'API](https://docs.aws.amazon.com/mediaconvert/latest/apireference/getting-started.html)
**Important**
Nous vous recommandons d'utiliser la MediaConvert console pour générer votre spécification de tâche JSON de production.
Les spécifications de votre tâche doivent être conformes à la validation par le moteur de transcodage. Les validations du moteur de transcodage représentent des dépendances complexes entre des groupes de paramètres et des dépendances entre vos paramètres de transcodage et les propriétés de vos fichiers d'entrée. La MediaConvert console fonctionne comme un générateur de tâches interactif pour faciliter la création de spécifications JSON valides pour les tâches. Vous pouvez utiliser des [modèles de tâches](using-a-job-template.md) et [des préréglages de sortie](using-a-preset-to-specify-a-job-output.md) pour démarrer rapidement.
Pour utiliser ces exemples, remplacez les valeurs de l'espace réservé suivantes par les valeurs réelles :
+ ARN DU RÔLE
+ s3://amzn-s3-demo-bucket
+ s3://amzn-s3-demo-bucket1

## Exemple : ABR automatisé
Cet exemple de spécification de tâche JSON spécifie une pile ABR automatisée dans Apple HLS. En plus de spécifier les paramètres ABR automatisés, il définit explicitement les valeurs suivantes :
+ Transcodage `Mode` accéléré vers `PREFERRED`
+ `rateControlMode` sur `QVBR`
+ `qualityTuningLevel` sur `MULTI_PASS_HQ`
Pour plus d'informations sur les paramètres ABR automatisés, consultez[ABR automatisé](auto-abr.md).
