If two files have the same Quality (e.g., both are Bluray-1080p), Sonarr will now choose the one with the higher Custom Format score. Alternative: Release Profiles (Sonarr v3)
: Do not put x265 in the "Must Contain" box unless you want to strictly block all x264 releases. Using "Preferred" allows Sonarr to grab an x264 version immediately and then "upgrade" to x265 later when it becomes available.
Now, because the qualities are viewed as equal, Sonarr will use your Custom Format scores (+100 for x265) as the primary deciding factor. Setting Size Limits to Filter Out Bloat
| Custom Format | Score | Purpose | |---|---|---| | x265 Preferred | +100 | Prefer HEVC when available | | x265 + 1080p Only | +1000 | Heavily favor HEVC for HD content | | Block x264 | -10000 | Prevent x264 downloads entirely | | Trusted Groups (ELiTE, QxR, etc.) | +50 | Favor high-quality release groups | sonarr prefer x265

x265, also known as High Efficiency Video Coding (HEVC), is a video compression standard designed to succeed H.264/AVC (x264). It offers significantly better compression efficiency than its predecessor, meaning it can store or stream video at a much smaller file size without a noticeable decrease in video quality. This efficiency is crucial for media enthusiasts who want to save on storage costs and bandwidth without sacrificing video quality.
"Alright," he whispered, cracking his knuckles. "Let's put some 'High Efficiency' into this Video Coding." He navigated to the Now, because the qualities are viewed as equal,
This is where the x265 video codec (also known as HEVC or High Efficiency Video Coding) becomes a lifesaver. It delivers the same visual quality as the older x264 codec at roughly half the file size.
A Custom Format does nothing until it is assigned a score in a .
Sonarr relies entirely on the release title to evaluate custom formats. If a release doesn't include "x265," "HEVC," or similar identifiers in its name, Sonarr cannot know what codec it uses.
