Rarbg X265 Encoding Settings Better

If you are using HandBrake to encode your library using these optimized settings, structure your pipeline like this:

It is highly likely that RARBG utilized CPU-based software encoding (x265 via standard x86 servers) rather than GPU hardware encoding (NVIDIA NVENC, Intel QuickSync, or AMD AMF).

To get better settings than RARBG, you need to fix what they broke while keeping their file size philosophy.

RARBG's x265 encoding philosophy focused on achieving a high balance of visual quality and efficiency, typically targeting file sizes of . Their encodes were known for being "Main 10" (10-bit), which reduces color banding even on 8-bit displays. rarbg x265 encoding settings better

The trade-off: (about 30–50% slower than default medium preset) and slightly higher peak bitrate for complex scenes.

Always encode in 10-bit ( hevc_nvenc or x265 10-bit), even if your source video is standard 8-bit.

Turn SAO back on ( --sao ) and use --aq-mode 1 . Animation benefits from flat, smooth color gradients and doesn't require complex grain retention. If you are using HandBrake to encode your

Increase --psy-rd to 2.5 and set --rc-lookahead to 60 . This prevents the grain from turning into digital noise.

RARBG uses a custom FFmpeg-based encoder. You can use the following settings in RARBG:

Even if your source video is 8-bit (standard SDR Blu-ray), you should always encode using the x265 10-bit pipeline. Their encodes were known for being "Main 10"
