To achieve a true workflow, you must respect Sonarr's quality hierarchy. Here are two effective strategies:
This is particularly common among Plex users with underpowered servers, as transcoding x265 to x264 for incompatible clients can be extremely CPU-intensive. Hardware acceleration (Intel Quick Sync, NVIDIA NVENC, or AMD VCE) can mitigate this, but not all setups have access to these features.
To make Sonarr prefer x265, you must use to give x265 files a higher score than x264 files within the same Quality Profile. Step-by-Step Configuration Guide sonarr prefer x265
Implementing a "prefer x265" workflow in Sonarr requires moving beyond basic quality profiles and utilizing . This comprehensive guide will walk you through the technical advantages of x265, the mechanics of Sonarr’s release profiles, and a step-by-step setup to prioritize efficient encodes automatically. Why Prioritize x265 in Your Media Library?
After saving your settings, test the configuration to ensure it behaves correctly: Go to any TV show in your library. To achieve a true workflow, you must respect
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.
: Files are typically 30% to 50% smaller than x264 files at identical visual qualities. To make Sonarr prefer x265, you must use
Once an episode achieves a score of 100 (by being encoded in x265), Sonarr will mark it as permanently completed and cease monitoring for further upgrades, saving your automated search loop unnecessary work. Advanced Tweaks: Avoiding Low-Quality Encodes
Sonarr provides users with the flexibility to configure their download and media management preferences, including the ability to prioritize x265 encodes. By adjusting the settings in Sonarr to prefer x265, users can automate the process of adding x265 versions of their TV shows and movies to their collection. This involves configuring the indexer and download client settings within Sonarr to look for and download x265 encoded files.

A common misconception in the self-hosted community is that x265 always looks better. According to the definitive automation benchmarks on TRaSH Guides, many release groups aggressively compress 1080p x265 files to tiny bitrates ("microsizing"), which introduces macroblocking and visual artifacts. The goal is to instruct Sonarr to grab while falling back to x264 if no good option exists. Step 1: The Modern Method – Custom Formats (Sonarr v4)
