Recommended naming scheme
On the Sonarr Discord people often ask, "What's the recommended/best way to name your files?" First off, it's personal preference, but it's often recommended to add non-recoverable info.
Why?
If, for what ever reason, you ever need to do a re-install or re-import in the Starr Apps or Plex/Emby/Jellyfin it's nice to have all that info in the filename so it gets imported correctly and isn't incorrectly matched as HDTV or WEB-DL etc.
The Tokens not available in the release won't be used/shown.

Sonarr V4 - Is now using Custom Formats instead of Release Profiles. Use the below naming scheme instead

Series Folder Format
{Series TitleYear}
RESULT:
The Series Title! (2010)
Optional Series Folder Format for the Plex TV Series Scanner and Jellyfin/Emby
This naming scheme is made to be compatible with the new Plex TV Series Scanner that now support IMDB and TVDB IDs in file names.
For Plex:
{Series TitleYear} {imdb-{ImdbId}}
RESULT:
The Series Title! (2010) {imdb-tt1520211}
For Jellyfin/Emby:
{Series TitleYear} [tvdbid-{TvdbId}]
RESULT:
The Series Title! (2010) [tvdbid-tt1520211]
Tip
IMDb IDs are going to be very accurate and rarely change, TVDB/TMDB IDs, on the other hand, do change or are removed more frequently.
Season Folder Format
For this there's only one real option to use in my opinion.
Season {season:00}
RESULT:
Season 01
Multi-Episode Style
Prefixed Range
RESULTS:
Original Title vs Original Filename
Another option is to use {Original Title} rather than the recommeneded naming scheme outlined aboove. {Original Title} will use the title of the release which will contain all of the information included in the release itself. The benefit of this naming scheme is to prevent download loops which can occur on import when there is a discrepancy in the release title compared to the contents of the file itself (for example, if the release title says DTS-ES but the contents are actually DTS). The downside is less flexibility with how the files are named.
If using this alternate naming scheme I suggest using {Original Title} over {Original Filename}
Why?
The filename can be Obscured where the Release naming isn't, especially when you use Usenet.
{Original Title} => The.Series.Title.S01E01.Episode.Title.1080p.AMZN.WEB-DL.DDP5.1.H.264-RlsGrp
{Original Filename} => show episode 1-1080p or lchd-tkk1080p or t1i0p3s7i8yuti
