Here is a command that captures the essence of RARBG's 1080p encoding logic, as used by GalaxyRG265:

RARBG encoded a massive portion of their library in 10-bit color. The encoder was set to 10-bit ( input-csp=1 ), which allows for vastly superior color gradients and helps completely eliminate color banding in dark scenes or expansive skies.

This is the secret weapon. Encoding in 10-bit prevents "banding" (blocky gradients in skies or dark rooms), even if your input video is standard 8-bit. It also compresses slightly better than 8-bit. 3. Preset and Speed Parameter: --preset slow Rarbg X265 Encoding Settings

This biases bit distribution toward dark scenes. Low-bitrate x265 encodes often suffer from "artifacts" or pixelation in shadows. Mode 3 prevents dark areas from turning into a muddy mess.

High-quality but compressed (typically 6-channel AC3 or AAC at 224-384 kbps). -x265-params aq-mode=3:aq-strength=1

RARBG used a modified version of the x265 encoder. While they tweaked settings over the years, the core parameters generally looked like this:

Select Peak Framerate and keep it at Constant Framerate (typically 23.976 for films).

To understand RARBG's settings, you first need a solid grasp of the core pillars of x265 encoding.

The RARBG settings implicitly turned off sao via the aggressive aq-mode=3 . Disabling SAO is an advanced technique used to retain fine image grain and film texture, preventing the overly smooth, "plastic" look that plagues many automatic HEVC encodes.

RARBG used a mix of automated variable bitrate (VBR) 2-pass encoding and Constant Rate Factor (CRF). The encoder was set to 10-bit ( input-csp=1
