title: AWS elastic transcoder batch transcoding
body: <p>Is it possible to transcode all .extensions in a bucket to an output bucket with one job? O r do I need to create a job for every single input file in a bucket using the api? </p>
  
  <p>If I can use one job for all files in a bucket with a certain extension, how do I do that?  Or if there is some way to automate transcoding based on just uploading a file to a bucket, how do I do it?</p>
