SlimeCodec Convert v0.3.3 — Windows x64 (GUI + CLI)
====================================================

Just double-click slimecodec-gui.exe. Pick input video, select codec
(H.264 / AV1), click Encode. NormMAP commutator-norm ROI is applied
on both paths.

H.264: in-process libx264 — production-grade, NormMAP fully effective.
AV1:   dispatches to slimecodec-svtav1-norm.exe → SvtAv1EncApp.exe
       (bundled, see below) → SVT-AV1 native --roi-map-file path so
       NormMAP ROI is also fully effective.

  slimecodec-gui.exe           Unified GUI (codec H.264/AV1 selector + About)
  slimecodec-svtav1-norm.exe   AV1 native ROI pipeline (called for AV1 output)
  slimecodec-svtav1-roi.exe    Standalone .normmap → SVT-AV1 ROI map gen
  SvtAv1EncApp.exe             AV1 encoder backend (BUNDLED, BSD-licensed)

AV1 default tunings (chosen so already-AV1 sources also shrink):
  --crf 38           CRF 32 was too quality-conservative (CityHall AV1→AV1
                     came out +50% larger than source). 38 lands at -18.8%
                     on CityHall + VMAF 94.22.
  --qp-range 30      Phase 2 sweet spot; --strength dial floors at 30.
  --strength 0.48    aggressive (qp-range 48), CityHall → 9 MB at VMAF 91+
                     "visually indistinguishable" per user testing.

CityHall 4K AV1 (17.94 MB source) → NormAV1 sweep:
  defaults (qpr=30 crf=38): 14.56 MB (-18.8%) / VMAF 94.22 (balanced)
  --strength 0.40 --crf 40: 11.80 MB (-34.2%) / VMAF 93.26
  --strength 0.48 --crf 42:  9.3  MB (-48%)   / VMAF 91+
                                              (matches NormH.264 size,
                                               +8 VMAF higher)
