Note on Scoring: The score (+10) is arbitrary but should be significant enough to outweigh other minor preferences. If a x264 release has a slightly better audio format (e.g., TrueHD vs AAC), a high x265 score ensures the x265 codec is still prioritized if storage is the primary concern.
Episodes encoded in x265 can be 30% to 50% smaller than their x264 counterparts, drastically extending the life of your hard drives. sonarr prefer x265
: Ensure your "Upgrade Until" quality is set high enough, and that you have enabled Allow Upgrades . Sonarr will now see an x265 release as a "better" version of the same quality. 3. (Optional) Set Negative Scores for x264 Note on Scoring: The score (+10) is arbitrary

Smaller file sizes require less bandwidth to download and stream remotely. : Ensure your "Upgrade Until" quality is set
Adjust the and Max sliders for your preferred qualities (like WEBDL-1080p) to accommodate the smaller footprint of HEVC files. Pro Tip: TRaSH Guides
However, blindly forcing x265 can result in "bad" releases (e.g., low-bitrate mini-encodes, aliased video, or unwanted HDR issues). This report outlines the technical implementation of a "Prefer x265" profile and provides critical safeguards to ensure quality is not sacrificed for compression.
