Specify the properties (renditionGroupId, renditionName or renditionLanguageCode) to identify the unique subtitle track among the alternative rendition groups present in the HLS manifest. If no unique track is found, or multiple tracks match the specified properties, the job fails. If there is only one subtitle track in the rendition group, the settings can be left empty and the default subtitle track will be chosen. If your caption source is a sidecar file, use FileSourceSettings instead of WebvttHlsSourceSettings.",
