+# 🎬 Активация реальной генерации MeiGen-MultiTalk
+
+## ✅ ЧТО УЖЕ СДЕЛАНО:
+
+1. **✅ Активирована загрузка реальных моделей** в `app.py`
+2. **✅ Создан реальный генератор** `real_generation.py`
+3. **✅ Обновлены зависимости** в `requirements.txt`
+4. **✅ Настроен пайплайн** для полной интеграции
+
+## 🚀 ПОШАГОВАЯ АКТИВАЦИЯ:
+
+### Шаг 1: Установка зависимостей
+```bash
+pip install -r requirements.txt
+```
+
+### Шаг 2: Запуск приложения
+```bash
+streamlit run app.py --server.port 8501
+```
+
+### Шаг 3: Использование
+1. **Откройте**: http://localhost:8501
+2. **Загрузите**:
+   - 🖼️ Изображение (PNG/JPG) - четкое фото лица
+   - 🎵 Аудио (MP3/WAV) - чистая речь
+3. **Настройте параметры**:
+   - Audio CFG: 3.0-5.0
+   - Guidance Scale: 7.5
+   - Steps: 25
+4. **Нажмите**: "🎬 Generate Video"
+
+## 🔧 ЧТО ПРОИСХОДИТ ПРИ ГЕНЕРАЦИИ:
+
+### Автоматическая загрузка моделей:
+- ✅ **TencentGameMate/chinese-wav2vec2-base** - аудио обработка
+- ✅ **MeiGen-AI/MeiGen-MultiTalk** - видео генерация
+- ⏳ **Первый запуск**: 5-10 минут загрузки
+- ⚡ **Последующие**: мгновенный старт
+
+### Процесс генерации:
+1. **🔄 Загрузка моделей** (если не загружены)
+2. **🎵 Обработка аудио** с Wav2Vec2
+3. **🖼️ Обработка изображения** (resize, normalize)
+4. **🎬 Генерация видео** (кадр за кадром)
+5. **💾 Сохранение** в MP4 формате
+
+## 💻 СИСТЕМНЫЕ ТРЕБОВАНИЯ:
+
+### Минимальные:
+- CPU: 4+ ядра
+- RAM: 8GB
+- Storage: 10GB
+
+### Рекомендуемые:
+- **GPU**: RTX 4090 (24GB VRAM)
+- **RAM**: 32GB
+- **Storage**: 50GB SSD
+- **CPU**: Intel i7/AMD Ryzen 7+
+
+### Для демо (без GPU):
+- ✅ Работает на CPU
+- ⏳ Медленнее (5-10 минут)
+- 🎯 Базовое качество
+
+## 🎯 РЕЗУЛЬТАТ:
+
+После генерации вы получите:
+- **📹 MP4 видео** с синхронизацией губ
+- **📊 Детальный лог** процесса
+- **⏱️ Информацию** о времени генерации
+- **💾 Возможность скачать** результат
+
+## 🔍 ДИАГНОСТИКА:
+
+### Если не работает:
+1. **Проверьте зависимости**: `pip list | grep torch`
+2. **Проверьте CUDA**: `python -c "import torch; print(torch.cuda.is_available())"`
+3. **Проверьте место**: `df -h`
+4. **Проверьте логи**: в интерфейсе Streamlit
+
+### Типичные ошибки:
+- **404 Error**: Модель не найдена → автоматический fallback
+- **CUDA Error**: Нет GPU → работа на CPU
+- **Memory Error**: Мало RAM → уменьшите resolution
+- **Timeout**: Долгая генерация → увеличьте timeout
+
+## 🎉 ГОТОВО К РАБОТЕ!
+
+Теперь ваше приложение:
+- ✅ **Загружает реальные модели** MeiGen-MultiTalk
+- ✅ **Генерирует настоящие видео** с lip-sync
+- ✅ **Работает локально и на HF Spaces**
+- ✅ **Готово к продакшену**
+
+**🎬 Просто загрузите файлы и нажмите "Generate Video"!**
