Wav2Lip Setup

Wav2Lip Project Setup Guide

Follow these steps to set up the Wav2Lip project on your Mac system. This guide covers installation of Python, setting up a virtual environment, cloning the Wav2Lip repository, and other necessary setup tasks.

Initial Setup Steps

Install Homebrew, a package manager for macOS, by running the following command in your terminal:
```
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
```
Use Homebrew to install Pyenv:
```
brew install pyenv
```
Create a project directory named Wav2LipProject:
```
mkdir Wav2LipProject
```
Navigate to Wav2LipProject:
```
cd Wav2LipProject
```
Use Pyenv to install Python 3.6:
```
pyenv install 3.6.15
```

Set Local Version:

pyenv local 3.6.15

Create virtual env using venv:
```
python -m venv Wav2LipEnv
```
Activate the Python 3.6 virtual environment:
```
source Wav2LipEnv/bin/activate
```
Verify the running version of Python:
```
python3 --version
```

Clone the Wav2Lip GitHub repository:

git clone https://github.com/Rudrabha/Wav2Lip.git
        cd Wav2Lip

Update pip:
```
pip install --upgrade pip
```

Install OpenCV:

pip install opencv-contrib-python==4.2.0.34

Install necessary Python libraries from requirements.txt:
```
pip install -r requirements.txt
```

Download the pretrained model weights from the repository:

Download wav2lip_gan.pth from this repository, place it into the checkpoints folder.

Verify the installation by running a simple script:

python inference.py --checkpoint_path path-to-wav2lip_gan.pth --face path-to-video.mp4 --audio path-to-audio.wav

Final Product should appear in the results folder.

Tips for Using Wav2Lip

Always ensure the environment in the wav2lip_env directory is running python 3.6 before running scripts.
Video must be mp4 and audio must be .wav
Better results using lower quality video. Compressing to 1080 looks best. 720 executes faster but generates poor results.
Ensure the Wav2Lip directory is correctly set up before proceeding.
Ensure that the video is not longer than the audio
Run the main script for synchronization in the Wav2Lip directory.
