Sonarr Prefer X265 [work] -

The primary, and most compelling, reason to prefer x265 is . At identical visual quality, an x265 encoded file is typically 30-50% smaller than its x264 counterpart.

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

Sonarr uses (in Sonarr v3 and v4) to score and prioritize specific release attributes. By assigning positive scores to x265 tags, you instruct Sonarr to choose an x265 release over an x264 release whenever both are available. Follow these steps to set up x265 preferences in Sonarr v4. Step 1: Create the x265 Custom Format Open your Sonarr web interface. Navigate to Settings > Custom Formats . Click the + Plus icon to add a new custom format. Name the format something clear, such as Prefer x265 . Under the Specifications section, click Add Specification . Select Release Title from the dropdown menu.

Whether you're building a space-saving 720p HEVC collection or assembling a pristine 4K library with Dolby Vision, Sonarr's custom format system gives you the tools to achieve your goals. The key is patience in configuration, attention to detail in scoring, and a willingness to refine your approach based on actual results. sonarr prefer x265

If you already have a large library of x264 content and want to migrate to x265, Sonarr alone isn't the right tool for the job. Sonarr is designed for content, not re-encoding it.

x265 (HEVC) offers ~50% better compression than x264 at the same quality, saving significant storage space. However, it’s more computationally demanding to play back – fine on modern devices, but problematic on older hardware or Plex/Jellyfin without GPU transcoding.
