When running a seedbox, you're bound to get files with several different codecs and file extensions, some of which are inefficient when it comes to compression. I believe that by adding tdarr, it can be make the files smaller and more uniform by trans-coding them to a codec and extension of choice. This should be a good addition as it is a web app and is able to be integrated with sonarr/radarr/whisparr as seen here https://docs.tdarr.io/docs/tools-and-integrations
