Always choose Peak Framerate or Same as Source , and ensure Variable Framerate (VFR) or Constant Framerate (CFR) matches the native 23.976 fps of the Blu-ray.

To get better results than standard scene releases, you must tweak the balance between encoding speed, bitrate control, and psychovisual settings. 2. Rate Control: CRF vs. Target Bitrate
If you'd like to fine-tune this setup for your specific library, tell me: rarbg x265 encoding settings better
Turn this off. SAO is notorious for blurring fine details, faces, and film grain, resulting in a "plastic" or "waxy" look. Disabling it keeps the image sharp.
RARBG rarely used 2-pass target bitrate encoding because it wastes bits on simple scenes and starves complex scenes. They relied on CRF. CRF 22 to 24 for 1080p. For 4K UHD: CRF 24 to 26 .
These offsets lower the quantization parameter for chroma (color) channels. It prevents color bleeding and ensures vibrant, accurate color representation even at lower bitrates. 3. Audio and Subtitle Optimization Always choose Peak Framerate or Same as Source
This is the most critical setting. By default, x265 enables SAO, which aggressively blurs the image to save bitrate. Disabling SAO ( no-sao=1 ) preserves fine details, textures, skin pores, and natural film grain, giving you a significantly sharper, "better than RARBG" output.
RARBG's x265 (HEVC) releases were legendary for their efficiency
Why: A CRF of 20 yields slightly better visual transparency than standard RARBG releases, especially in dark gradients and high-motion sequences, with only a marginal increase in file size. 2. Encoder Preset Rate Control: CRF vs
By following these guidelines, you should be able to achieve a good balance between quality and file size for your x265-encoded videos on RARBG. Happy encoding!
: Keep the original track only if it is already compressed Dolby Digital (AC3) or DTS.
RARBG was legendary for its massive library of high-efficiency video coding (HEVC/x265) releases. While the original site is gone, the encoding philosophy established by its release groups remains the gold standard for balancing sharp 1080p/4K visual quality with incredibly small file sizes.
It is crucial to note that the "RARBG Settings" discussed above were designed specifically for content. RARBG did produce 4K x265 HDR releases, but they used a different set of rules.
A major reason RARBG files remained small was their treatment of audio. They did not pass through heavy, uncompressed audio tracks like DTS-HD Master Audio or TrueHD, which can easily take up 3GB to 5GB per movie.
