RARBG used a modified version of the x265 encoder. While they tweaked settings over the years, the core parameters generally looked like this:
H.265 (10-bit) or H.265 (2160p 10-bit for 4K). Note: 10-bit reduces color banding, even for 8-bit sources. Framerate (FPS): Same as source (Peak Framerate).

The core of the RARBG "look" relied on a specific combination of bitrates, 10-bit color depth, and standardized x265 parameters. Standard Encoding Parameters
Setting --bframes 4 with an adaptive mode of --b-adapt 2 allowed the encoder to find the absolute most efficient way to track fast-moving objects. RARBG used a modified version of the x265 encoder
RARBG's power came from its custom -x265-params , which fine-tune the encoder's behavior in ways that presets alone cannot.
For nearly two decades, RARBG stood as one of the most prominent torrent sites on the internet. While the site ceased operations in 2023, its legacy remains a benchmark for digital video distribution, particularly in the realm of High Efficiency Video Coding (HEVC), known technically as x265. Unlike many release groups that prioritize speed over quality, RARBG developed a reputation for consistent, high-quality encodes that balanced file size with visual fidelity. This essay explores the technical encoding settings employed by RARBG for x265 releases, analyzing how specific parameters were utilized to address the challenges of bandwidth, storage, and playback compatibility. Framerate (FPS): Same as source (Peak Framerate)
Set the slider to Slow or Very Slow . (Slower presets force the encoder to do more mathematical calculations to find the best possible compression).
Rarbg X265 encoding settings offer a great balance between file size and video quality, making them an excellent choice for users who want to enjoy their favorite content on various devices. By understanding the benefits and settings of X265 encoding on Rarbg, users can optimize their download experience and enjoy high-quality video playback.

The definitive guide to RARBG x265 encoding settings focuses on balancing high-definition visual quality with the aggressive file size reduction that made the group legendary. RARBG's "x265" or "HEVC" releases became the gold standard for efficiency, often delivering 1080p content at a fraction of the bitrate used by traditional x264 encodes.
