The Ultimate Guide to Sonarr and x265: How to Prefer, Prioritize, and Perfect Your HEVC Library
In the world of digital hoarding and home media servers, space is the final frontier. As 4K becomes standard and TV series box sets stretch into hundreds of gigabytes, the question is no longer "Can I store it?" but "How long can I afford to store it?"
Enter the codec war: x264 (H.264) versus x265 (HEVC) . For Sonarr users, the battle is fought in the "Release Profiles" tab. If you have ever typed "sonarr prefer x265" into a search bar, you are likely frustrated by bloated 1080p files or struggling to make a 2TB hard drive stretch across a decade of Doctor Who.
This article will guide you through everything you need to know about forcing Sonarr to prefer x265, the pitfalls of transcoding, and the hardware required to actually play these files back. sonarr prefer x265

Mastering Sonarr: How to Prioritize x265 (HEVC) and Reclaim Your Storage Space
In the world of home media servers, storage space is the ultimate luxury. As we curate 4K remuxes, complete TV series box sets, and high-bitrate Blu-ray rips, it’s alarmingly easy to fill a 20TB array.
Enter x265 (HEVC). This video codec offers roughly double the compression efficiency of the aging x264 (H.264). Switching your downloads to x265 can save you terabytes of space without sacrificing visual quality. Part 5: The Hardware Realities of an x265
But there is a catch: Sonarr (and its cousin Radarr) does not have a native "I only want x265" button. Without proper configuration, Sonarr will grab the first release that meets its quality profile—usually the more common, larger x264 file.
