Yuuki-3.5-AC3b

Rebuilt with mingw-w64-clang-x86_64-clang-15.0.7-2. For internal testing purposes only.

Kyouko-3.5-AC2b

Rebuilt with mingw-w64-clang-x86_64-clang-15.0.7-2. For internal testing purposes only.

Yuuki-3.5-AC3 No silent failures

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 the XLENGTH y4m 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)

Kyouko-3.5-AC

This release incorporates aMod's aq mode 5 (see DJATOM/x265-aMod#17. Thanks @noizuy and @DJATOM that make this release possible). As the user interface is now different from Yuuki mod's, to avoid confusion, a new version tag Kyouko is chosen (was thinking about using Yuuki+aMod as tag, but it seems too weird and besides it doesn't include all aMod's enhancements to warrant including the aMod tag....)

New options:

--aq-mode: <0|1|2|3|4|5>
      3. .... You can use aq-bias-strengh to adjust the bias towards dark scenes.
      5. AQ enabled with auto-variance, edge information, and bias to dark scenes.
--aq-bias-strength <float>
      Adjust the strength of dark scene bias in AQ modes 3 and 5. Setting this
      to 0 will disable the dark scene bias, meaning modes will be equivalent to
      their unbiased counterparts (2 and 4).
      Default 1.0.

The behavior should match that of the original Yuuki mod if you don't set any of the new parameters.
