What are you using to encode? (HandBrake, FFmpeg, StaxRip, etc.) What CPU do you have?
Look for the line that says Encoding settings . A "better" RARBG-style encode will usually have parameters like:
By upgrading the encoder preset to , fixing the dark-scene artifacting with aq-mode=3 , and pushing the psychovisual options ( psy-rd ), you will generate files that match the compact footprint of classic RARBG releases while delivering visibly superior clarity, deeper shadow detail, and vastly improved grain retention. If you want to fine-tune your encoding setup, let me know: What hardware CPU/GPU you are using to encode?
RARBG used low settings to speed up their server racks. On modern consumer hardware, you should force the encoder to analyze motion properly to eliminate blockiness. rarbg x265 encoding settings better
When pursuing "better" settings, ensure you are utilizing and not Hardware Accelerated Encoders like NVIDIA NVENC, Intel QSV, or AMD VCE. Software (libx265) Hardware (NVENC / QSV) Quality per Megabyte Extremely High (Best) Moderate (Wastes Bits) Granular Fine-Tuning Complete Control Highly Restricted Processing Speed Slow (CPU Bound) Blazing Fast (GPU Bound) Best Used For Archival / Perfect Storage Live Streaming / Fast Scans
One of the great aspects of RARBG's settings is their broad device compatibility. 10-bit x265 encodes play smoothly on almost any modern device, including smart TVs, streaming boxes, and mobile phones. If you experience playback issues, ensure your client supports HEVC Main 10 decoding.
Optimal for 4K content to keep file sizes manageable without visible artifacts. What are you using to encode
If you want to duplicate or improve upon the legendary RARBG x265 encoding settings using tools like HandBrake or the FFmpeg CLI, this guide will break down the exact parameters, CRF values, and advanced command-line arguments required to maximize your encoding efficiency. The RARBG Philosophy: Bitrate vs. Transparency
Why? Going lower than CRF 20 unnecessarily inflates the file size without a human-perceptible increase in quality. Going higher than CRF 25 introduces noticeable blockiness in dark scenes. 2. Encoder Preset: The Efficiency Driver
x265 is a highly efficient video encoding standard that offers better compression than its predecessor, x264. It's widely used for 4K and high-definition video encoding due to its ability to reduce file sizes while maintaining video quality. x265 encoding uses a variety of settings to control the encoding process, including preset, bitrate, CRF (Constant Rate Factor), and more. A "better" RARBG-style encode will usually have parameters
Avoid Slower or Very Slow unless you have a high-end workstation; the massive increase in encode time only yields a 1–2% increase in compression efficiency. 4. Advanced Command Line Parameters (CLI)
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
content, which is about half the size of standard x264 encodes while maintaining similar perceived quality. Comparison to Other Groups Review Consensus Target Audience Sweet spot for quality/size; very consistent. High-volume collectors, small screens. Higher quality and transparency; larger file sizes. Quality enthusiasts, large TVs. Comparable to RARBG in size; often uses 10-bit. Extreme storage savers. Lower quality tier; prone to heavy compression artifacts. Mobile devices, low bandwidth.

Hardware encoders are designed for speed and live streaming; they require significantly higher bitrates to achieve the same visual clarity as software encoding. To get the best results, stick to the software . While it will take longer to finish, the space saved and the crispness of the final video are unparalleled. Summary Checklist for Your Next Encode Recommended Value Video Codec H.265 10-bit (x265) Eliminates color banding, improves compression. Framerate Same as Source (Variable) Prevents stuttering or duplicate frames. Quality CRF 20 (1080p) / CRF 22 (4K) Matches perceptual transparency. Encoder Preset Enables advanced efficiency algorithms. Advanced Flags no-sao=1:aq-mode=3 Retains fine details and cleans up dark scenes. Audio Opus or AAC (5.1 at 320kbps) Saves massive space while retaining surround depth.
