Rarbg X265 Encoding Settings [ 2025 ]
Crush the bitrate, but kill the grain.
: Uses rc=abr with a specific qcomp=0.60 value, which balances the bitrate distribution between complex (high motion) and simple scenes. Philosophical Trade-offs: Quality vs. Size
If you have a modern CPU (Intel Arc, NVIDIA 40-series, or Apple M2/M3), you can improve on RARBG's speed using hardware encoding, but you'll lose quality. For pure CPU encoding, stick to their settings. However, add one modern flag: Rarbg X265 Encoding Settings
, you should focus on controlled bitrates rather than high-quality presets. RARBG Encoding Settings - GitHub Gist
Because 10-bit encoding eliminates color banding (those ugly stripes in smooth gradients like sunsets or fog) even when the source is 8-bit . Crush the bitrate, but kill the grain

, making them playable on nearly all hardware, including older smart TVs and mobile devices. Standardized 1080p HEVC Specifications Size If you have a modern CPU (Intel
| Content Type | Modification | Rationale | | :--- | :--- | :--- | | | CRF 20, psy-rd=2.0 | Sharp but grain-free. | | Live Action (Grainy) | CRF 21, nr-intra=100 | Added noise reduction to kill grain before encoding. | | Animation / Anime | CRF 18, aq-mode=4 | Animation has flat colors. Lower CRF preserves edges. aq-mode=4 is better for cartoons. | | Low Motion (Talk Shows) | bframes=16 | Extreme B-frame usage for static sets. |
Before we look at the numbers, you must understand RARBG's philosophy. They were aiming for archival master quality (like a 80GB REMUX). They were aiming for "transparent compression"—the point where a 2.5GB movie looks virtually identical to a 25GB source on a 55-inch TV from 8 feet away.
RARBG rarely used the default Medium or the placebo Veryslow . Their sweet spot was .
