Are you interested in creating high-quality lip-synced videos? Look no further! This guide will walk you through using the Wav2Lip-HD repository, which combines the Wav2Lip and Real-ESRGAN algorithms to produce stunning results. With just a few steps, you can create videos that are both accurate and visually captivating.

Understanding the Algorithm

Let’s break down the process by using a fun analogy. Imagine you are a master chef preparing a multi-layered cake. The Wav2Lip algorithm is like the baking phase; it takes in your ingredients (the video and audio) and creates the foundation (lip-synced frames). Next, you apply the Real-ESRGAN algorithm, which acts like a frosting that enhances and beautifies your cake, resulting in a high-quality video ensemble. Once all layers blend perfectly, you use ffmpeg to present your masterpiece as a delightful cake (your output video) ready to be shared!

Step-by-Step Instructions to Run Wav2Lip-HD

• Clone the Repository: Open your terminal and run the following commands to clone the repository and install necessary requirements (ensure Python and CUDA are installed):

git clone https://github.com/saifhassan/Wav2Lip-HD.git
cd Wav2Lip-HD
pip install -r requirements.txt

• Download Model Weights: Download the necessary model weights from the following links:
• Wav2Lip: checkpoints, Link
• ESRGAN: Link, Link
• Face Detection: Link, Link
• Real-ESRGAN Weights: Link, Link
• Prepare Input Files: Place your input video in the input_videos directory and the audio in the input_audios directory.
• Modify the Run Script: Open the run_final.sh file and adjust the following parameters:
• filename=kennedy (replace with your video file name without extension)
• input_audio=input_audios/ai.wav (input your audio file name)
• Execute the Script: Run the script using the following command:

bash run_final.sh

• Check Outputs: The output directories will contain:
• output_videos_wav2lip – the video generated by the Wav2Lip algorithm
• frames_wav2lip – frames extracted from the Wav2Lip video
• frames_hd – frames improved using Real-ESRGAN
• output_videos_hd – the final high-quality lip-synced video

Troubleshooting Tips

• If you encounter issues during the cloning process, ensure that your internet connection is stable.
• For problems related to missing dependencies, double-check that all requirements are correctly installed, and consider using a virtual environment.
• Make sure all paths for input files in the run_final.sh script are correct and match the filenames in your directories.
• If the output videos are not playing correctly, confirm that your media player supports the output file format.
