+# Регулировка качества и измерение
+
+## Целевое качество
+- Ориентир: средний VMAF ≥ 93 для кодированного видео.
+
+## Что регулируем
+- GPU-энкодеры используют CQ (Constant Quality).
+- CPU-энкодеры используют CRF (Constant Rate Factor).
+- Значения по умолчанию взяты из текущей логики кодирования (см. `src/core/encoding.ts`) и могут быть переопределены через CLI (`--h264-cq`, `--h264-crf`, `--av1-cq`, `--av1-crf`).
+
+## Дефолтные CQ/CRF
+
+| Энкодер          | H.264           | AV1            |
+|------------------|-----------------|----------------|
+| NVENC            | CQ 32           | CQ 42          |
+| QSV              | CQ 32           | CQ 42          |

+| CPU (libx264 / libsvtav1) | CRF 25→20*    | CRF 40→28*    |
+
+\* CPU значения зависят от целевого разрешения:
+- 360p: H.264 CRF 25, AV1 CRF 40
+- 480p: H.264 CRF 24, AV1 CRF 38
+- 720p: H.264 CRF 23, AV1 CRF 35
+- 1080p: H.264 CRF 22, AV1 CRF 32
+- 1440p: H.264 CRF 21, AV1 CRF 30
+- 2160p: H.264 CRF 20, AV1 CRF 28
+
+## Как мерить качество (VMAF)
+1. Закодируйте тестовый ролик с нужными параметрами (CQ/CRF).
+2. Сравните с исходником по VMAF (разрешения должны совпадать, при необходимости приведите к одному размеру).
+3. Пример команды FFmpeg c libvmaf:
+   ```bash
+   ffmpeg -i encoded.mp4 -i source.mp4 \
+     -lavfi "[0:v]setpts=PTS-STARTPTS[enc];[1:v]setpts=PTS-STARTPTS[ref];[enc][ref]libvmaf=log_path=vmaf.json:log_fmt=json" \
+     -f null -
+   ```
+   В логах ищите `VMAF score`; если < 93 — увеличьте качество (понизьте CQ/CRF), если > 95 и нужен меньший битрейт — можно чуть поднять CQ/CRF.
