Fully statically linked x265 (8 & 10 & 12-bit, with dynamic HDR10+ support):
- ffmpeg 4.4 for input (mkv/m2ts/mp4 demuxer, ffv1/h264/hevc/huffyuv/ffvhuff decoders)
- mimalloc v2.0.2: reduce memory usage and improve allocation performance
- LTO (Link-Time Optimization): whole-program optimization
- PGO (Profile-Guided Optimization): profiling is for 10-bit only, using a set of representative https://github.com/AmusementClub anime encoding settings (which should generalize pretty well for generic quality-first encoding though: we're basically using --preset placebo --no-amp)
- Built with clang 13 for 64-bit Windows, requires UCRT support (Windows 10+ has it builtin, Windows 7/8 can install via Windows Update)
- (New in AC3) It will return non-zero exit value (
%errorlevel%) whenever errors occur during encoding (e.g. when the total encoded frames is less than theXLENGTHy4m header indicated)
Please download the release binary best matching your CPU micro-architecture.
If unsure, use the x86-64 version, which does not assume any specific x86-64 micro-architecture (which implies that it will be the slowest variant).
- Generic: x86-64 (no avx)
- Intel
- Alderlake, e.g. 12900K
- Skylake, e.g. 6700K (7-11th gen CPUs should also use this variant)
- Haswell: e.g. 4790K
- Ivybridge: e.g. 3770K
- AMD
- znver3 (Zen 3): e.g. 5950X
- znver2 (Zen 2): e.g. 3950X
- znver1 (Zen 1): e.g. 1800X
- bdver4 (Excavator)
