# Exemplo de configurações de trabalho JSONs
As configurações de trabalho nesses exemplos representam as tarefas válidas mais simples que você pode executar. Elas funcionam bem para experimentar o serviço. Quando quiser realizar transcodificações mais complexas ou criar saídas diferentes, use o console para configurar o trabalho e gerar a especificação de trabalho JSON. Para fazer isso, no painel **Trabalho** à esquerda, em **Configurações de trabalho**, escolha **Mostrar JSON de trabalho**.
*Para obter mais informações sobre como enviar seu trabalho de forma programática, consulte um dos tópicos introdutórios da Referência da API:AWS Elemental MediaConvert *
+ [Começando a AWS Elemental MediaConvert usar o AWS SDKs ou o AWS CLI](https://docs.aws.amazon.com/mediaconvert/latest/apireference/custom-endpoints.html)
+ [Começando a AWS Elemental MediaConvert usar a API](https://docs.aws.amazon.com/mediaconvert/latest/apireference/getting-started.html)
**Importante**
Recomendamos que você use o MediaConvert console para gerar sua especificação de trabalho JSON de produção.
Sua especificação de trabalho deve estar em conformidade com a validação do mecanismo de transcodificação. As validações do mecanismo de transcodificação representam dependências complexas entre grupos de configurações e dependências entre as configurações de transcodificação e as propriedades dos arquivos de entrada. O MediaConvert console funciona como um criador de tarefas interativo para facilitar a criação de especificações JSON de tarefas válidas. Você pode usar [modelos de trabalho](using-a-job-template.md) e [predefinições de saída](using-a-preset-to-specify-a-job-output.md) para começar a trabalhar rapidamente.
Para usar esses exemplos, substitua os seguintes valores de espaço reservado por valores reais:
+ FUNÇÃO ARN
+ s3://amzn-s3-demo-bucket
+ s3://amzn-s3-demo-bucket1

## Exemplo: ABR automatizado
Este exemplo de especificação de trabalho JSON especifica uma pilha ABR automatizada no Apple HLS. Além de especificar as configurações automatizadas de ABR, ele define explicitamente esses valores:
+ Transcodificação acelerada de `Mode` para `PREFERRED`
+ `rateControlMode` para `QVBR`
+ `qualityTuningLevel` para `MULTI_PASS_HQ`
Para obter mais informações sobre as configurações do ABR automatizado, consulte [ABR automatizada](auto-abr.md).
