How tiering works

Release group tiers assign scores based on a group’s track record for quality, encoding, naming, and consistency. Tier 01 groups are the most trusted; higher tier numbers indicate progressively lower confidence. Dumpstarr Database sources its tier data from two places:
  • Dictionarry — the primary source for WEB, Bluray, Remux, and Anime tiers. The group lists sync automatically each day.
  • TRaSH Guides — alternative tier formats are included as TRaSH WEB Tier 01/02/03 for users who prefer them.
Each format matches a release against its source type (WEB-DL, WEBRip, Bluray, etc.) and then checks the release group against the corresponding Dictionarry tier list. The score for each tier is set in the quality profile, not in the format itself.
All release group tier formats have an empty description field. Their scores are profile-specific and are configured in Profilarr when the format is applied to a profile.
WEB tiers cover groups that release WEB-DL and WEBRip content. They match against both web_dl and webrip source types.

1080p Bluray tiers cover groups that encode Blu-ray sources at 1080p. They require a bluray source, a 1080p resolution, and the release title must not contain Remux (to exclude remux releases from this tier).

2160p Bluray tiers cover groups that encode Blu-ray sources at 4K. The structure mirrors the 1080p tiers but requires a 2160p resolution and matches against the Dictionarry UHD tier lists.

Remux tiers cover lossless untouched rips from Blu-ray. Because Radarr and Sonarr detect remuxes differently, each tier ships as two separate formats — one for Radarr and one for Sonarr.Radarr uses the quality_modifier: remux condition:
name: Remux Tier 01 - Radarr
description: ''
tags:
  - Remux
  - Radarr
conditions:
  - name: Remux
    negate: false
    qualityModifier: remux
    required: true

  - name: Dictionarry Remux Tier 01
    negate: false
    pattern: Dictionarry Remux Tier 01
    required: false
    type: release_group

Sonarr uses the bluray_raw source type instead:
name: Remux Tier 01 - Sonarr
description: ''
tags:

conditions:
  - name: Remux
    negate: false

Anime tiers are split into two categories:
  • Anime Tier 1–8 — Bluray and DVD anime groups. These require a bluray or dvd source and match individual group names via release_title conditions.
  • Anime WEB Tier 1–6 — WEB-source anime groups. These explicitly negate bluray and dvd sources so they only match streaming rips.
Example — Anime Tier 1 (Bluray/DVD, top groups):
name: Anime Tier 1

BHDStudio and hallowed are treated as standalone formats rather than tier entries because they occupy a unique niche: they produce streaming-optimized encodes that are preferred in the standard Movies profiles.Both formats are Radarr-only (tagged Radarr) and match a single release group name with required: true.

Baseline Groups is a fallback format for groups that have a generally good reputation but are not ranked in any Dictionarry or TRaSH tier. It matches against the Dumpstarr Baseline Groups list, which is maintained in the Dumpstarr database.
name: Baseline Groups
description: >-
  This format will match against groups that have a generally good reputation
  in terms of audio, video and file naming quality, but are not tiered
  according to TRaSH/Dictionarry.
tags:

    negate: false
    pattern: Dumpstarr Baseline Groups

SIDCA (Sh*t I Don’t Care About) groups are release groups that are normally banned in standard profiles but are permitted in the 1080p LQ profile, where maximum storage savings outweigh source quality concerns.Two formats exist:
  • SIDCA Groups — the main list of typically-banned groups allowed in LQ profiles.
  • SIDCA Fallback Groups — a secondary fallback list for the same purpose.
name: SIDCA Groups
description: >-
  These are groups that are typically banned, but are allowed for the LQ
  profiles.
tags:
  - SIDCA
  - Dumpstarr
conditions:
  - name: Dumpstarr SIDCA Groups
    negate: false
    pattern: Dumpstarr SIDCA Groups
    required: false
