No don't, sonarr is definitely worse if you have a unstructured media folder. I currently use it and its good, but I remember when first starting out with pile of files in semi random folders it being a mess to start up. Like some of the restrictions of the bulk importer made very little sense. Also, sonarr is tied to a single metadata provider which sometimes makes very unpopular decisions about the naming of series and episodes. When pluribus was initally released, they insisted on naming the series "plur1bus" even though no other source, imdb or even AppleTV used that as the official name. This broke auto downloading for the season.
i've used this plugin a lot, and it is nice, but a bit hit-or-miss. it analyzes all episodes of a show to start seeing a pattern in the beginning of shows, or checks chapters which my files rarely had. works well for most shows, but if a show has unique intros for every episode, it doesn't really work. also had trouble with 100% consistent intros, but i never really figured out why that happened.
kind of a 50% solution, works a lot of times but a lot of other times you still end up scrubbing. (also consider that if you install this plugin onto a large existing library, it's going to take a considerable amount of compute and real-world time to do complete it for every show).
That sounds like what I see with Plex, too. It definitely doesn't get it when the intros are unique. And if there's something later that's the same each show (an explanation of the game show, etc) it'll target it as the intro instead.
ah i see, then they must use a similar process. i wonder how big streaming sites do it. underpaid global south workers who manually tag the intro for every episode, or do the files come pre-tagged by the production. maybe a mix of both.
