For the best results, many users follow the methodology. This involves adding negative scores to "bloat" terms or low-quality encoders. If you prefer x265, you might also want to give a negative score to x264 or AVC to ensure they are only picked as a last resort. Transcoding Constraints
You will see your "x265 HEVC" format listed. Set the to something positive, like 100 . sonarr prefer x265
As hardware decoding becomes universal, x265 provides the best balance of fidelity and footprint. Step 1: Create a Custom Format for x265 For the best results, many users follow the methodology
This guide will walk you through setting up custom formats and quality profiles to ensure your library shifts toward the x265 standard. Why Prefer x265? Transcoding Constraints You will see your "x265 HEVC"
Ensure your playback devices (Plex clients, smart TVs, or tablets) support HEVC hardware decoding. If they don't, your media server will have to transcode the x265 files back to x264 on the fly, which can heavily tax your CPU. Step 4: Applying the Changes
While x265 is superior for storage, there are two things to keep in mind to avoid a "bad" automated experience. Watch Out for "Trash Guides"
Now that Sonarr knows how to identify x265, you need to tell it that these files are more desirable than others. Go to . Select the profile you use (e.g., HD-1080p ). Find the Custom Formats section at the bottom.
