Sonarr Prefer X265 Today

Creating the format does nothing until you attach it to a Profile.

Purpose: Identify releases whose release title contains encoder/codec hints (x265, HEVC, 10bit, HDR terms). Sonarr can match custom formats to release titles for scoring. sonarr prefer x265

Examples to add (pattern matching is case-insensitive; use multiple entries for variants): Creating the format does nothing until you attach

Name: x265 10-bit

Name: HDR (for HDR x265 releases)

Name: x264 (so you can prefer x265 over this)

Best practice:

For remux/mux consistency (container changes, HDR metadata), use scripts to preserve subtitles, chapter markers, and HEVC metadata.

Ensure post-processing scripts update media server (Plex/Emby/Jellyfin) libraries and optionally update metadata agents.
