I also don’t think it’s appending the audio languages correctly in the resulting filenames.
I renamed all my files and everything was working properly except for the fact that it changed all release groups to “Sonarr”, bummer! Does this mean Sonarr didn’t detect the original release groups for my files? My old standard episode naming format was:
Looks like Sonarr really cannot parse the release group. Why? I’m assuming it should be AMZN. How is Sonarr’s logic in trying to determine the release group anyway?
What rename bug? So far neither thing you mentioned has been a bug.
Release group parsing is quite restrictive, typically following the pattern -RlsGroup (at the end) or [RlsGroup] (mainly anime), deviations from that won’t likely be parsed or parsed incorrectly.
Because there’s a lower boundary after which any release “name” becomes unparsable crap? Scene releases at least follow a pretty strict naming convention. Anime sort of does, it seems (I don’t have a lot of experience with it). Anything else is just the Wild West, and it’s not easy to write code to understand all the crazy names that people put out there…
There’s also the compulsive behavior some people have, where they add brackets or other fancy separators for no reason (imho), to the file names to make them look “pretty”, as if it’s still 1995 and people play files by browsing their hand-curated directories and double-clicking them. I haven’t seen any of my series folders in years, since people invented decent media portals like Plex, Kodi and others…
