metadataDestination property
Specify the Amazon S3 location where you want MediaConvert to save your Nielsen non-linear metadata .zip file. This Amazon S3 bucket must be in the same Region as the one where you do your MediaConvert transcoding. If you want to include an ADI file in this .zip file, use the setting ADI file (adiFilename) to specify it. MediaConvert delivers the Nielsen metadata .zip files only to your metadata destination Amazon S3 bucket. It doesn't deliver the .zip files to Nielsen. You are responsible for delivering the metadata .zip files to Nielsen.
