RARBG’s x265 releases were widely recognized for their efficient balance between file size and visual fidelity, often targeting a bitrate of approximately
for 1080p content. The group utilized a specialized version of the x265 library, evidenced by MediaInfo tags such as x265 3.3+4-rarbg Core Encoding Strategy
The RARBG "Standard" for 1080p x265 (HEVC) releases typically followed these parameters: Target Bitrate for video. Resolution
: 1920 pixels wide, with height varying based on aspect ratio (e.g., 800px for 2.40:1). : Consistent use of
(Main 10@L4 profile), which reduces "banding" artifacts in gradients even at lower bitrates. : Standardized at 224 kbps AAC 5.1
or 2-channel, ensuring compatibility across most modern devices. Typical Encoding Parameters (MediaInfo Analysis)
Based on metadata from verified releases, the following settings were commonly observed: Observed Value RC (Rate Control) (Average Bitrate) or Maintains consistent file size across the library.
Enhanced Adaptive Quantization for better dark scene handling. bframes=16 High number of B-frames to maximize compression efficiency. Psychovisual Rate-Distortion to keep fine detail/grain. De-blocking
Adjusted based on source grain; lower values prevent blurring.
Sample Adaptive Offset is often disabled to prevent "smearing" of fine textures. Replicating the "RARBG Look" via FFmpeg
To achieve similar results for a 1080p source, you can use the FFmpeg libx265 encoder with these approximate settings:
ffmpeg -i input_source.mkv \ -c:v libx265 -preset slow -crf \ -pix_fmt yuv420p10le \ -x265-params "aq-mode=3:no-sao=1:ref=6:bframes=8:psy-rd=1.5" \ -c:a aac -b:a \ output_rarbg_style.mp4 Use code with caution. Copied to clipboard Contextual Notes
The RARBG x265 encoding settings were long considered the gold standard for public trackers, balancing small file sizes with surprisingly high visual fidelity. While the original RARBG site has shut down, their encoding philosophy remains a benchmark for efficient library building. The Verdict: High Efficiency, Minimal Bloat
The RARBG "Galaxy" style of x265 encoding is best for users who want a high-definition experience without sacrificing hard drive space. It is not "transparent" (perfectly identical to the source), but it is exceptionally clean for its size. 💿 Key Strengths
Storage King: Files are often 50–70% smaller than x264 counterparts.
Consistent Quality: They utilized a 10-bit depth, which significantly reduces "banding" in dark scenes or gradients (like skies).
Device Compatibility: Designed to work on most modern Smart TVs, tablets, and streaming boxes (like Nvidia Shield or Apple TV).
Clean Metadata: Encodes typically included well-timed subtitles and standard AAC or AC3 audio for maximum compatibility. ⚠️ Potential Drawbacks
Detail Loss: In high-motion scenes or very "grainy" films, the aggressive compression can soften fine textures compared to a full Blu-ray remux.
Audio Trade-offs: To keep file sizes tiny, they often opted for 2.0 or 5.1 lossy audio rather than lossless Atmos or DTS-X tracks.
CPU Intensive: While great for playback, x265 requires more processing power to decode on very old hardware. 🛠 Summary of the RARBG "Style" Codec: HEVC (x265)
Bit Depth: 10-bit (Standard for their high-quality releases) Resolution: Primarily 1080p and 2160p (4K)
Ideal for: Binge-watching TV shows and building a massive movie collection on a budget.
💡 Pro Tip: If you are archiving a "forever" copy of your favorite masterpiece, a Remux is better. For everything else, the RARBG x265 settings offer the best "bang for your buck" in the digital world.
If you are trying to replicate these settings in Handbrake or FFmpeg, would you like a breakdown of the specific CRF and preset values they typically used?
RARBG was well-known for its highly efficient 1080p x265 (HEVC) encodes, which balanced small file sizes (often around 1.5GB–2.5GB) with high visual clarity. While the official RARBG group shut down in May 2023, their encoding "formula" was widely emulated by other groups like ION10.
The core of the RARBG "look" relied on a specific combination of bitrates, 10-bit color depth, and standardized x265 parameters. Standard Encoding Parameters
RARBG's typical 1080p x265 releases were generally based on the following technical profile:
Video Bitrate: ~2000–2500 kbps (for 1080p) and ~1500 kbps (for 720p). Rarbg X265 Encoding Settings
Rate Control: They typically used 2-pass encoding or a very strictly tuned CRF (Constant Rate Factor) of 22–24 to ensure predictable file sizes.
Color Depth: 10-bit (Main 10 profile). This is critical because 10-bit encoding reduces "banding" in dark scenes and gradients even at low bitrates.
Audio: Typically 6-channel AAC or AC3 at 224 kbps, which saved space compared to lossless formats like DTS-HD. Implementation (FFmpeg Example)
To achieve a result similar to a RARBG/ION10 release, you can use the following FFmpeg command, which approximates their standard 1080p parameters:
ffmpeg -i input.mkv \ -c:v libx265 -crf 22 -preset slow -pix_fmt yuv420p10le \ -x265-params "strong-intra-smoothing=0:rect=0" \ -c:a aac -ab 224k -ac 6 \ output.mp4 Use code with caution. Copied to clipboard Key RARBG "Tweak" Settings
Advanced users often point to specific x265-params used by high-efficiency scene groups to preserve detail at low bitrates:
Preset: Slow or Slower. Slower presets allow the encoder more time to find optimal compression paths, which is essential for maintaining quality at sub-3000 kbps bitrates.
strong-intra-smoothing=0: Disabling this prevents the encoder from "blurring" flat surfaces, which helps maintain natural film grain or texture.
rect=0: Disabling rectangular motion partitions can sometimes speed up the encode without a significant loss in quality for standard 1080p content.
aq-mode: Typically set to 3 (Enhanced Auto-Variance), which helps distribute bitrate more effectively in dark scenes where x265 often struggles. Quality Trade-offs
The RARBG "Small Size" strategy prioritized storage efficiency over "transparent" quality. While excellent for mobile devices or casual viewing, these settings may show "blockiness" or artifacts on very large 4K displays compared to a full Blu-ray rip. For high-end archival, community consensus often suggests a lower CRF of 18–20.

The Quest for the Perfect Encode
In the world of video encoding, there existed a legendary uploader known only by their handle "RARBG". For years, they had been perfecting the art of compressing high-quality video files using the x265 codec. Their mission was to make high-definition video accessible to everyone, without sacrificing quality.
One day, a young and ambitious video enthusiast named Alex stumbled upon RARBG's uploads. Alex was amazed by the crystal-clear pictures and relatively small file sizes. Determined to learn the secrets behind RARBG's magic, Alex embarked on a journey to discover the optimal x265 encoding settings.
Alex began by researching the basics of x265 encoding, studying the intricacies of quantization, psycho-visual modeling, and entropy coding. As they dived deeper, they realized that finding the perfect settings would require a combination of technical expertise and trial-and-error experimentation.
RARBG, observing Alex's eagerness, decided to share some valuable insights. They revealed that their go-to settings involved a delicate balance between bitrate, preset, and quality. The ideal settings, RARBG claimed, were:
Alex took these settings as a starting point and began experimenting. They encoded various test files, adjusting parameters and analyzing the results. The journey was not without setbacks, as Alex encountered issues with encoder compatibility, file corruption, and lengthy encoding times.
As Alex continued to refine their skills, they discovered the importance of AQ (Adaptive Quantization). By enabling AQ, Alex could further reduce bitrate while maintaining visual quality. They also explored psy-rd, which helped preserve the nuances of complex scenes.
Through tireless testing and perseverance, Alex eventually developed their own set of optimized RARBG-inspired x265 encoding settings:
The results were stunning. Alex's encodes matched, if not surpassed, RARBG's renowned quality. File sizes were remarkably small, and the video fidelity was exceptional.
RARBG, impressed by Alex's dedication and achievements, welcomed them into the community of elite video encoders. Together, they continued to push the boundaries of x265 encoding, sharing knowledge and expertise to create the most efficient and visually stunning video files.
From that day forward, Alex and RARBG collaborated on various projects, optimizing encoding settings for diverse use cases. Their partnership helped make high-quality video more accessible, fostering a new generation of enthusiasts who shared their passion for exceptional video encoding.
The legend of RARBG and their x265 encoding settings lived on, inspiring others to strive for excellence in the art of video compression.
RARBG officially shut down in May 2023, meaning there are no "official" new RARBG x265 encode settings being released. However, during its run, the scene giant set the gold standard for high-quality, low-file-size video encodes.
By analyzing their massive catalog, video enthusiasts successfully reverse-engineered the exact parameters RARBG used for their famous x265/HEVC releases.
Here is the complete breakdown of the RARBG x265 encoding settings, how to replicate them in HandBrake, and why they worked so well. 📌 The Core RARBG x265 Settings
RARBG prioritized a perfect balance between visual fidelity and aggressive file size reduction. They utilized the HEVC (x265) codec, which is roughly 50% more efficient than the older x264 (AVC) standard. RARBG’s x265 releases were widely recognized for their
To replicate their exact rips, use these command-line parameters or input them into your encoding software: 1. The Command Line (CLI) Parameters
If you are using FFmpeg or the x265 CLI directly, these are the core parameters found in RARBG video metadata:
crf=22:preset=slow:no-sao=1:aq-mode=3:aq-strength=1.0:psy-rd=2.0:psy-rdoq=1.0:deblock=-1:-1 2. Parameter Breakdown CRF (Constant Rate Factor): 22
This controls the quality. RARBG typically used 21 or 22 for 1080p content. Lower numbers mean higher quality but larger files. Preset: Slow
This determines the encoding speed. "Slow" provides much better compression efficiency than "Medium" without taking days to encode. No-SAO: 1 (Disabled)
Crucial step. Sample Adaptive Offset (SAO) is on by default in x265, but it tends to cause a slight blur or loss of fine detail (like skin texture). RARBG disabled this to keep images sharp. AQ-Mode: 3
Adaptive Quantization mode 3 biases toward dark scenes. This prevents ugly pixelation and color banding in dark areas of a movie. Psy-RD: 2.0 & Psy-RDOQ: 1.0
These settings enhance the "psychovisual" quality, keeping film grain and fine textures looking natural rather than flat or plastic-like. Deblock: -1:-1
Slightly lowers the default deblocking filter to prevent the video from looking too soft, maintaining edge sharpness. 🛠️ How to Replicate RARBG Settings in HandBrake
HandBrake is the easiest free tool to use if you want to encode your own media library using the RARBG methodology. Follow this step-by-step setup: Video Codec: H.265 (x265) Framerate: Peak Framerate (or Same as source) Encoder Preset: Slow
Constant Quality: 22 RF (You can use 20 for better quality, or 24 for smaller size).
Advanced Options: In the box at the bottom, paste the following string:no-sao=1:aq-mode=3:aq-strength=1.0:psy-rd=2.0:psy-rdoq=1.0:deblock=-1:-1
RARBG was famous for not just video compression, but keeping audio highly compatible. For Stereo: AAC (avcodec), 128 kbps or 160 kbps. For Surround Sound: AC3 or E-AC3, 448 kbps or 640 kbps.
Pass-thru: They often used auto-passthrough for the original Dolby Digital track to save processing power and preserve quality. 💡 Why the RARBG Formula Worked So Well
You might wonder why these specific settings became the benchmark for a generation of torrent users.
Dark Scene Handling: x265 natively struggles with dark gradients, often creating "blocks" of color. AQ-Mode 3 fixed this entirely for RARBG.
Texture Preservation: By disabling SAO and bumping up the Psy settings, they avoided the "plastic wax" look common in early heavy-compression HEVC encodes.
Universal Compatibility: By sticking to Main profile and standard leveling, their files played flawlessly on everything from high-end PCs to cheap Android TV boxes and iPads. ⚠️ A Note on Hardware Encoding (NVENC / VCE)
If you are looking to replicate RARBG settings, do not use hardware encoders like Nvidia NVENC or AMD VCE in HandBrake.
While hardware encoders are incredibly fast (encoding a movie in minutes), they cannot utilize the advanced psychovisual and SAO settings listed above. Hardware encoding requires much higher bitrates to achieve the same visual quality as software (CPU) encoding. RARBG strictly used CPU software encoding to achieve their legendary efficiency.
To achieve video quality and file sizes similar to the renowned RARBG releases, you should focus on a 2-pass average bitrate encoding strategy rather than Constant Rate Factor (CRF). This approach ensures predictable file sizes while maintaining high visual efficiency. Core x265 Video Settings
RARBG typically targeted specific bitrates to balance quality and size. You can replicate this by using FFmpeg or Handbrake with these parameters: 1080p Settings: Target a bitrate of 2500 kbps.
Preset: slow (The x265 Documentation notes this trades speed for better compression).
Profile: Main 10 (10-bit encoding is standard for HEVC to reduce banding).
Advanced Parameters: aq-mode=3 (to improve quality in dark/flat areas) and bframes=8 (to increase compression efficiency). 720p Settings: Target a bitrate of 1500 kbps.
Audio: RARBG often used AAC 5.1 at 224 kbps for surround sound or AAC 2.0 for stereo content. Command Line Examples
According to community-shared RARBG Encoding Settings on Gist, here is how you might structure a command:
# 1080p Example using FFmpeg ffmpeg -i input.mkv -c:v libx265 -b:v 2500k -x265-params "pass=1:preset=slow:aq-mode=3:bframes=8" -an -f mp4 /dev/null && \ ffmpeg -i input.mkv -c:v libx265 -b:v 2500k -x265-params "pass=2:preset=slow:aq-mode=3:bframes=8" -c:a aac -ab 224k -ac 6 output.mp4 Use code with caution. Copied to clipboard Key Considerations Alex took these settings as a starting point
Encoding Speed: Using the slow preset is critical for matching RARBG’s efficiency, but it requires significantly more processing power than medium or fast.
Grain Preservation: For older or grainy films, experts on Selur's Forum suggest using the --tune grain parameter or avoiding overly aggressive bitrates to prevent the image from looking "smeared".
2-Pass vs. CRF: While RARBG favored bitrates (2-pass), many users on Reddit now prefer CRF 20–22 for a "set and forget" approach that adjusts bitrate based on scene complexity.

By mastering Rarbg X265 encoding settings, you'll be able to enjoy your favorite video content in a more efficient and flexible way. Happy encoding!
RARBG x265 releases were not designed to be transparent to the source (matching the Blu-ray perfectly) nor were they "mini-encodes" (aggressively shrinking files to 500MB). Instead, they targeted the "Golden Middle":
Before diving into commands, you must understand their target. RARBG was not a "remux" group (lossless rips). They catered to users with moderate bandwidth and storage constraints. Their goal was transparency at normal viewing distances.
For nearly two decades, RARBG was a titan in the digital torrenting world. While the site shut down in 2023, its legacy lives on through its meticulously crafted internal releases. Among tech-savvy archivists and home theater enthusiasts, one question remains persistent: What encoding settings did RARBG use for their x265 (HEVC) releases?
The "RARBG x265" profile became legendary for balancing tiny file sizes (often 1.5GB to 2.5GB for a 1080p movie) with surprisingly high visual fidelity. This article deconstructs the exact command lines, CRF values, preset tunings, and filter chains that defined the RARBG encode style. Whether you want to replicate their quality or simply understand why their releases looked better than other scene groups, this is your technical deep dive.
If RARBG x265 had a weak point, it was the audio philosophy.
RARBG adopted x265 (HEVC) relatively early. While x264 (AVC) was the universal compatibility king, x265 offered roughly 50% better compression. For a site hosting thousands of movies, this meant lower bandwidth costs and happier users with small hard drives.
But x265 is notoriously finicky. Bad settings produce "blocky" shadows or "waxy" skin tones. RARBG didn't have bad settings.
Grain is the enemy of x265. RARBG used a light denoise filter via -vf hqdn3d to tame grain before encoding.
-vf "hqdn3d=1.5:1.5:3:3" -c:v libx265 -preset medium -crf 20 \
-x265-params "no-sao=1:deblock=-2,-2:psy-rd=1.5:psy-rdoq=5.0"
