 CLI tool to convert videos to DASH and HLS with hardware acceleration (NVENC / Intel QSV / AMD AMF / VAAPI), adaptive streaming, and automatic thumbnails/poster.
 
 **Features:**
-- ⚡ Hardware acceleration: NVENC / Intel QSV / AMD AMF / VAAPI (auto priority)
+- ⚡ Hardware acceleration: auto-detect encoder/decoder (NVENC / Intel QSV / AMD AMF / VAAPI / CPU)
 - 🎯 Formats: DASH and HLS (shared segments)
 - 📊 Quality profiles: multiple bitrates/FPS (auto or custom)
 - 🖼️ Preview: thumbnail sprite + VTT, poster from the first frame
 - ⏱️ Progress: per-profile and overall CLI progress bars
 
-## Quick Start
+## Install
-
+For the CLI to work correctly, FFmpeg and MP4Box must be installed in the system.
-```bash
-# Run via npx (no install)

+- `-f, --format` — `dash` | `hls` (по умолчанию auto = dash + hls).
+- `-p, --poster` — таймкод постера (`HH:MM:SS` или секунды, по умолчанию 0:00:00).
+- `-e, --encoder` — аппаратный/софт энкодер: `auto` | `cpu` | `nvenc` | `qsv` | `amf` | `vaapi` | `videotoolbox` | `v4l2`.
+- `-d, --decoder` — аппаратный/софт декодер: `auto` | `cpu` | `nvenc` (cuda) | `qsv` | `vaapi` | `videotoolbox` | `v4l2`.

+
+## Что передаём в FFmpeg
+- `cpu` (энкодер) → H.264: `libx264`, AV1: `libsvtav1`.
+- `nvenc` → `h264_nvenc`, `av1_nvenc` (если доступен).

+- `videotoolbox` → `h264_videotoolbox` (macOS).
+- `v4l2` → `h264_v4l2m2m` (зависит от SoC).
+
+Декодеры:
+- `cpu` — без `-hwaccel`.
+- `nvenc` — `-hwaccel cuda -hwaccel_output_format cuda`.
+- `qsv` — `-hwaccel qsv`.
+- `vaapi` — `-hwaccel vaapi -vaapi_device /dev/dri/renderD128`.
+- `videotoolbox` — `-hwaccel videotoolbox`.
+- `v4l2` — `-hwaccel v4l2m2m`.
+
+## Особенности
+- В авто-режиме AV1 включается только при наличии аппаратного AV1; иначе остаётся H.264.

+# 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          |
+| AMF              | CQ 32           | CQ 42          |
+| VAAPI            | CQ 32           | CQ 42          |
+| videotoolbox     | CQ 32           | CQ 42          |
+| v4l2             | 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.
