python inference.py \
    --checkpoint_path checkpoints/wav2lip.pth \
    --face input.mp4 \
    --audio audio.wav \
    --outfile output.mp4
```

### Alta calidad (GAN)

```bash
python inference.py \
    --checkpoint_path checkpoints/wav2lip_gan.pth \
    --face input.mp4 \
    --audio audio.wav \
    --outfile output.mp4 \
    --pads 0 10 0 0 \
    --resize_factor 1
```

text_to_lipsync(
    "Hello, welcome to our presentation.",
    "presenter.jpg",
    "talking_presenter.mp4"
)
```

## Postprocesamiento

### Mejorar resultado

```python
import subprocess

def upscale_video(input_path, output_path):
    cmd = [
        "python", "-m", "realesrgan",
        "--input", input_path,
        "--output", output_path,
        "--scale", "2"
    ]
    subprocess.run(cmd, check=True)
```

### Agregar audio de nuevo

```bash

# Si se perdió el audio, volver a agregarlo
ffmpeg -i synced_video.mp4 -i original_audio.wav \
    -c:v copy -c:a aac \
    -map 0:v:0 -map 1:a:0 \
    final_output.mp4
```

## Solución de problemas

### Rostro no detectado

* Asegúrate de que la cara sea claramente visible
* Buena iluminación
* Preferible de frente
* Entrada de mayor resolución

### Mala calidad de sincronización

* Usar wav2lip\_gan.pth
* Ajustar el relleno
* Verificar la tasa de muestreo del audio (se recomienda 16 kHz)

### Salida entrecortada

* Aumentar resize\_factor
* Desactivar nosmooth
* Usar video de entrada de mayor calidad
