Enhance the sound of your online audio stream.
Available only in Rocket Broadcaster Pro.
Polish your stream and automatically master your audio with advanced digital signal processing. Our unique Automatic Gain Control (AGC) and Multiband Compressor bring out the detail in your stream, creating a more comfortable listening experience across a wide range of content.
Get key information about your audio at a glance. The oscilloscope, stereo vectorscope, ITU BS.1770 Loudness Meter, and scrolling waveforms give you the tools you need to rapidly identify and fix audio quality issues. The resizable window is optimized for High DPI / 4K displays.
By disabling SAO, leaning on a Slow encoding preset, and opting for 10-bit color depth, your home encodes will actually surpass the quality of old RARBG releases while maintaining the highly compressed, hard-drive-friendly file sizes you miss.
There is no single "official" RARBG x265 setting from a deep paper, because RARBG was a release group, not a research lab. However, their internal encoding logic (for the & RARBGx265 releases) was widely studied by scene groups. Based on forensic analysis of their releases and general x265 tuning for 1080p/2160p, here are the de facto RARBG-like settings that produced their signature "small file size but decent grain retention."
RARBG’s 1080p and 2160p x265 releases were highly optimized for compatibility and efficient streaming. They prioritized a few specific goals:
This is where the magic happens. RARBG utilized specific tweaks that are not enabled even by the "slow" preset by default: rarbg x265 encoding settings better
The most reliable information regarding RARBG's internal process comes from "GalaxyRG265," a later group that explicitly stated: . The command line they published serves as the definitive blueprint for replicating the RARBG style.

According to internal posts from TorrentGalaxy's release group GalaxyRG265 (who specifically stated they took RARBG x265 as a base and modified it to their liking), the core video encoding command line looked like this: By disabling SAO, leaning on a Slow encoding
The goal here is to prevent the CRF algorithm from skyrocketing the bitrate during incredibly complex scenes (like explosions, confetti, or heavy rain), which could result in absurdly large file sizes. Setting this cap ensures that even the most chaotic action scene won't bloat the movie, acting as a final check and balance for file size predictability.

CRF is the holy grail of video encoding. Instead of forcing a specific bitrate (which wastes data on simple scenes and breaks apart on complex ones), CRF maintains a consistent visual quality. RARBG targeted a . In the x265 ecosystem, the default is 28 (visually low quality). A CRF of 22 is considered the industry standard for "transparent" or high-quality 1080p encodes. Lower numbers (18-20) result in near-lossless quality but explode file sizes. RARBG recognized that 22 is the point where quality is nearly indistinguishable from the source for 1080p material while maintaining practical file sizes.
To surpass them, you should move away from their fixed-bitrate approach and embrace a workflow that preserves more detail while keeping the "small footprint" spirit alive. ⚙️ The "Better than RARBG" Encoding Blueprint

To achieve this, they relied on a fine-tuned balance of Constant Rate Factor (CRF), specific x265 presets, and custom command-line arguments to retain film grain and detail. The "Better Than RARBG" Benchmark Settings
Here’s how to improve upon the original formula:
Master your stream audio without having to upgrade your PC. Our Broadcast Audio Processor is highly optimized, operating with nearly negligible additional CPU usage or RAM on most modern PCs. Optimized for streaming with only 15 milliseconds of audio latency.
The Broadcast Audio Processor uses 100x less RAM than the leading VST processor plugin, saving you from expensive hardware upgrades.
Hit the optimal volume level optimized for your listeners' devices. Ensures your stream is neither too quiet on mobile devices with weak speakers, nor too loud causing distortion. The ITU BS.1770 Loudness Meter measures the LUFS of your stream, and feeds back into the AGC to automatically optimize the loudness of your stream.
The BS.1770 Loudness Meter works intelligently with our Hybrid Two-Stage AGC to preserve the dynamics of music while achieving your programme loudness target.
The Broadcast Audio Processor is available exclusively in Rocket Broadcaster Pro 1.4+.
