RARBG (and similar high-efficiency release groups like ION10) typically aimed for a "sweet spot" where file sizes are small enough for quick sharing but quality remains high enough for a clear viewing experience on 1080p screens
. While they never officially published their exact scripts, their encoding parameters can be reverse-engineered from the metadata found in their releases.
To get better results that mimic or improve upon RARBG’s x265 style, use the following configuration guidelines for tools like 1. The Core RARBG "Formula"
RARBG usually targeted specific average bitrates rather than using Constant Quality (CRF). However, for most home users,
is superior because it ensures consistent quality regardless of how complex a scene is.
Understanding x265 Encoding Settings
Before we dive into specific settings, let's cover some basics:
- x265: Also known as HEVC (High Efficiency Video Coding), x265 is a video compression standard that offers better compression efficiency than x264 (H.264) at the cost of increased computational complexity.
- Preset: A preset determines the tradeoff between encoding speed and compression efficiency. Faster presets sacrifice some compression efficiency for quicker encoding, while slower presets offer better compression at the cost of longer encoding times.
Recommended x265 Encoding Settings for RARBG
Here are some settings that can help you achieve a good balance between quality and file size:
- Preset: Medium or Slow (depending on your system's processing power and the desired encoding time). If you're in a hurry, Medium is a good compromise. For best quality, use Slow.
- CRF (Constant Rate Factor): 18 or 20. CRF controls the bitrate and quality. Lower values (e.g., 18) result in larger files with better quality, while higher values (e.g., 20) produce smaller files with slightly lower quality.
- Tune: film or animation (depending on the content type). This setting adjusts the encoding parameters for specific content types, which can improve quality.
- Profile: main10 (for 10-bit encoding) or main (for 8-bit encoding). main10 offers better color accuracy and dynamic range, but requires more storage space.
- Level: 5.1 or 5.2 (depending on your hardware and desired compatibility). A higher level allows for more complex content, but may not be supported by all devices.
Example Settings
Here's an example of x265 encoding settings for RARBG:
ffmpeg -i input.mkv -c:v libx265 -preset medium -crf 18 -tune film -profile:v main10 -level 5.1 output.mkv
RARBG Specific Settings
RARBG uses a custom FFmpeg-based encoder. You can use the following settings in RARBG:
- Go to Settings > Encoder > Custom.
- In the Custom Encoder section, select x265 as the encoder.
- Set Preset to Medium or Slow.
- Set CRF to 18 or 20.
- Set Tune to film or animation.
- Set Profile to main10 or main.
Tips and Considerations
- Source material: The quality of your source material greatly affects the encoding outcome. Make sure you're working with a good quality source.
- System resources: Encoding with x265 can be computationally intensive. Ensure your system has sufficient processing power, RAM, and storage space.
- File size: x265-encoded files are generally larger than x264-encoded files. Consider your storage space and bandwidth limitations when choosing encoding settings.
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!
To achieve "better" results than standard RARBG x265 encodes (which often prioritized speed and small file size), you can use the following improved x265 settings. These adjustments focus on preserving detail and reducing artifacts like blocking and banding. Optimized x265 Encoding Settings
For a balance of high quality and efficiency, use these settings in tools like HandBrake or via FFmpeg command lines: Recommended Value Why It's "Better" Encoder x265 10-bit
Reduces "banding" (color blocking) in dark scenes, even for 8-bit sources. Rate Control CRF 20–22
A lower Constant Rate Factor (CRF) provides higher quality. RARBG often used higher values (~24) to save space. Preset Slow or Slower
RARBG typically used "Medium." Slower presets allow the encoder more time to find optimal compression, improving clarity. AQ Mode 3 (Auto-variance with dark bias)
Better preserves detail in dark/shadowy areas where x265 often struggles. B-Frames 8
Increasing B-frames (from RARBG's standard 3 or 4) improves compression efficiency for complex motion. SAO Limit-SAO or No-SAO
Standard "SAO" can cause blurring. Limiting it preserves fine textures like skin and film grain. Example Command Line (FFmpeg)
If you are using FFmpeg, you can try this high-quality string that mimics and then improves upon the RARBG style:
ffmpeg -i input.mkv -c:v libx265 -crf 21 -preset slow -x265-params "aq-mode=3:bframes=8:no-sao=1:psy-rd=1.5:psy-rdoq=2.0" -c:a copy output.mkv Use code with caution. Copied to clipboard Key Comparison: RARBG vs. Optimized
Audio: RARBG often used low-bitrate AAC (224kbps for 5.1). To improve this, use AC3 at 384–448kbps or DTS/TrueHD pass-through to keep the original master quality.
Resolution: For grainy or older films, encoding at 720p with a high bitrate often looks better than a "starved" 1080p encode. If you'd like, I can help you: Set up a HandBrake preset specifically for these settings.
Find settings for animation/anime, which require different tuning (e.g., higher psy-rd). Adjust these for HDR 4K content.
Mastering RARBG-Style x265 Encoding: How to Get Better Quality and Smaller Files
If you’ve spent any time on torrent indexers, you’ve likely seen the legendary RARBG (x265) releases. Even though the original site has moved on, their encoding philosophy remains the gold standard for many: achieving a "transparent" look (where it’s hard to tell the difference from the source) while keeping file sizes incredibly low.
If you’re looking to replicate or improve upon those settings for your own media library, you need to balance the efficiency of High Efficiency Video Coding (HEVC) with the right parameters. Here is how to dial in your x265 encoding settings for better results. 1. The Core Philosophy: Efficiency vs. Quality
The goal of a RARBG-style rip is not "lossless" quality—it’s perceptual quality. This means throwing away data the human eye can't easily see while preserving sharp edges and grain. The Recommended "Base" Settings
For most users using Handbrake or StaxRip, these are the foundation settings: Encoder: x265 (10-bit) Rate Control: Constant Quality (RF) Preset: Slow (or Slower) Profile: Main 10 2. Why 10-bit is Non-Negotiable
Even if your source is 8-bit (like a standard Blu-ray), you should always encode in x265 10-bit.
Better Compression: 10-bit handles gradients (like sunsets or shadows) much better, drastically reducing "banding" artifacts.
Efficiency: Paradoxically, 10-bit x265 often results in a smaller file size than 8-bit at the same perceived quality because the encoder has a more precise mathematical workspace. 3. Finding the "Sweet Spot" for RF (Rate Factor)
RARBG releases typically targeted specific bitrates, but for personal use, Constant Quality (RF) is superior. 1080p Content: RF 20 to 22. 4K Content: RF 22 to 24.
Action/High Detail: If the movie is "busy" (like Saving Private Ryan), drop the RF by 1–2 points (e.g., to RF 19) to prevent blockiness. 4. The "Secret Sauce": Command Line Parameters
To truly get "better" results than standard presets, you need to add custom arguments. In Handbrake, these go in the "Advanced Options" box. For Film (Preserving Grain and Detail)
aq-mode=3:psy-rd=2.0:psy-rdoq=1.0:rd=4:tu-intra-depth=3:limit-modes=1
aq-mode=3: This is the "dark scene fix." It prevents blocking in dark areas, a common x265 weakness.
psy-rd: Higher values (2.0+) keep the film grain intact, preventing the "waxy" look. For Animation/Clean Digital Sources aq-mode=1:psy-rd=0.5:psy-rdoq=1.0:bframes=8
Animation needs less "noise" preservation and benefits from more B-frames to keep file sizes tiny. 5. Preset Choice: Why "Slow" Matters The Preset slider determines how hard the encoder works.
Medium: The default. Good, but often "smudges" fine detail to save time.
Slow: The sweet spot. This enables features like rect and amp (Advanced Motion Prediction) that make x265 significantly more efficient than x264.
Slower: Use this if you have a powerful CPU and want the absolute smallest file size possible for a specific quality level. 6. Audio: Don't Neglect the Sound
A common mistake is encoding a beautiful 2GB video file but leaving a 1.5GB DTS-HD Master Audio track attached. To mimic the RARBG style: Codec: AAC (avcodec) or Opus. Bitrate: 224kbps to 640kbps (for 5.1 Surround).
Opus is technically superior at lower bitrates, but AAC has better compatibility with older TVs. Summary Checklist for "Better" Rips: Use 10-bit regardless of the source. Set Preset to Slow—it's worth the wait. Use RF 20–22 for a perfect balance of size and clarity.
Add aq-mode=3 to ensure your dark scenes don't look like a pixelated mess.
Denoise sparingly. Only use a "Light" HQDN3D filter if the source is excessively grainy.
By using these settings, you’ll produce files that look nearly identical to the original Blu-ray while taking up only 10–15% of the space.
6. Why They Were "Better" Than the Competition
The main reason RARBG settings were considered "better" by the general public was consistency.
- No Bitstarving: Unlike many public torrent sites where encoders crush bitrates to save bandwidth, RARBG releases rarely suffered from visible artifacts like "color banding" (visible lines in skies) or "blocking" (pixelation in dark scenes).
- Source Selection: RARBG encoders almost always started from high-quality sources (REMUX or Web-DL) rather than re-encoding already compressed files. Re-encoding an encode (generational loss) destroys quality; RARBG avoided this trap.
- Hardware Compatibility: While some niche encoders use the latest x265 builds with experimental settings that crash old TVs, RARBG stuck to stable settings that were compatible with a wide range of hardware (Smart TVs, Roku, Shield).
Part 3: Why "Better" Than RARBG is Easy (2025+)
To get better settings than RARBG, you need to fix what they broke while keeping their file size philosophy.
The 3 weaknesses of RARBG encodes:
- Grain destruction: Action movies (Die Hard, Aliens) looked smeary.
- Anime banding: Their settings struggled with gradients in animated skies.
- Subtitle burn-in: They hardcoded English subs only, wasting bitrate.
The 3 modern advantages you have:
- x265 version 3.5+ (40% better psychovisual optimization)
- AV1 vs. x265 analysis (We can use smarter x265 tune settings)
- SVT-AV1 as a backup (But this article stays on x265)
Typical technical choices you’ll see
- x265 HEVC in MKV containers
- Presets around medium/slow for a compromise of time and quality
- Tune settings favoring film/movie characteristics
- CRF or two-pass VBR targeting modest average bitrates (to save space while preserving detail)
- Audio: stereo AC3 or 5.1 AC3/EAC3, sometimes FLAC or TrueHD as a lossless option
3. Upgrade --no-sao to --limit-sao
Simply turning SAO off (--no-sao) saves texture but creates visual "popping" artifacts. Better: Use --limit-sao with --sao-non-hevc. This keeps SAO only where absolutely necessary, preventing the blurry "plastic" look while avoiding temporal flicker.
