For 720p or older content, increase CRF to . For grainy film, drop psy-rd to 1.5 to avoid excessive bitrate spikes.
As 4K content became standard, RARBG x265 releases became the go-to source for non-HDR TV owners. rarbg x265 encoding settings better
Likely multi-pass or CBR (Constant Bitrate) to ensure predictable file sizes. Profile: Main 10@L4.0 or similar. For 720p or older content, increase CRF to
RARBG never used Intel QSV, NVIDIA NVENC, or AMD VCE for x265. if you want "better." Likely multi-pass or CBR (Constant Bitrate) to ensure
| Setting | Value | Why RARBG used it | |---------|-------|--------------------| | | main10 | 10-bit encoding – better compression, less banding | | Preset | medium | Best speed/compression trade-off | | CRF | 19–22 | Lower CRF = higher quality; they often used 20 for 1080p | | AQ-mode | 3 (Auto-Variance) | Preserves detail in dark/flat areas | | No SAO | Disabled | Prevents blurring of fine detail (slightly less compression, sharper image) | | Deblock | -2:-2 | Stronger deblocking filter to reduce blocking artifacts at low bitrates | | Psy-RD / Psy-RDOQ | 2.0 / 1.0 | Retains film grain and texture – crucial for “better” subjective quality | | RDOQ level | 2 | More precise quantization – better detail retention per bit | | ME | star | More thorough motion estimation (better than umh or hex) | | B-frames | up to 8 | Improves compression in still/low-motion scenes |
For a balance of efficiency and "transparent" quality, use these settings in Handbrake or FFmpeg:
