## 💡 Description
This repository contains a Wav2Lip Studio Standalone Version. 

It's an all-in-one solution: just choose a video and a speech file (wav or mp3), and the tools will generate a lip-sync video, faceswap, voice clone, and translate video with voice clone (HeyGen like). 
It improves the quality of the lip-sync videos generated by the [Wav2Lip tool](https://github.com/Rudrabha/Wav2Lip) by applying specific post-processing techniques.

## 🐍 Usage
##PARAMETERS
1. Enter project name and click enter.
2. Choose a video (avi or mp4 format). Note avi file will not appear in Video input but process will works.
3. Face Swap (take times so be patient):
   - **Face Swap**: choose the image of the faces you want to swap with the face in the video (multiple faces are now available), left face is id 0.
4. **Resolution Divide Factor**: The resolution of the video will be divided by this factor. The higher the factor, the faster the process, but the lower the resolution of the output video.
5. **Min Face Width Detection**: The minimum width of the face to detect. Allow to ignore little face in the video.
6. **Align Faces**: allows for straightening the head before sending it for Wav2Lip processing.
7. **Keyframes On Speaker Change**: Allows you to generate a keyframe when the speaker changes. This allows you to better control the video generation.
8. **Keyframes On scene Change**: Allows you to generate a keyframe when the scene changes. This allows you to better control the video generation.
9. When parameters above are set click on **Generate Keyframes**, See [Keyframes manager](#keyframes-manager) section for more details.
10. Audio, 3 options:
      1. Put audio file in the "Speech" input. or record one with the "Record" button. 
      2. Generate Audio with the text to speech [coqui TTS](https://github.com/coqui-ai/TTS) integration.
         1. Choose the language
         2. Choose the Voice
         3. Write your speech in the text area "Prompt" in text format or json format:
            1. Text format: 
               ```bash
               Hello, my name is John. I am 25 years old.
               ```
            2. Json format (you can ask chat GPT to generate discussion for you):
                ```bash
                [
                  {
                    "start": 0.0,
                    "end": 3.0,
                    "text": "Hello, my name is John. I am 25 years old.",
                    "speaker": "arnold"
                  },
                  {
                    "start": 3.0,
                    "end": 4.0,
                    "text": "Ho really ?",
                    "speaker": "female_01"
                  },
                  ...
                ]
                ```
         4. Input Video: Allow to use audio from the input video, voices cloning and translation. see [Input Video](#input-video) section for more details.
11. **Video Quality**: 
    - **Low**: Original Wav2Lip quality, fast but not very good.
    - **Medium**: Better quality by apply post processing on the mouth, slower.
    - **High**: Better quality by apply post processing and upscale the mouth quality, slower.
12. **Wav2lip Checkpoint**: Choose beetwen 2 wav2lip model:
    - **Wav2lip**: Original Wav2Lip model, fast but not very good.
    - **Wav2lip GAN**: Better quality by apply post processing on the mouth, slower.
13. **Face Restoration Model**: Choose beetwen 2 face restoration model:
    - **Code Former**:
      - A value of 0 offers higher quality but may significantly alter the person's facial appearance and cause noticeable flickering between frames.
      - A value of 1 provides lower quality but maintains the person's face more consistently and reduces frame flickering.
      - Using a value below 0.5 is not advised. Adjust this setting to achieve optimal results. Starting with a value of 0.75 is recommended.
    - **GFPGAN**: Usually better quality.
14. **Volume Amplifier**: Not amplify the volume of the output audio but allows you to amplify the volume of the audio when sending it to Wav2Lip. This allows you to better control on lips movement.

## KEYFRAMES MANAGER
![Illustration](demo/keyframes-manager.png)

Global parameters:
1. **Only Track The Mouth**: This option tracks only the mouth, removing other facial motions like those of the cheeks and chin.
2. **Only show Speaker Face**: This option allows you to only focus the face of the speaker, the other faces will be hidden.
3. **Frame Number**: A slider that allows you to move between the frames of the video.
4. **Add Keyframe**: Allows you to add a keyframe at the current Frame Number.
5. **Remove Keyframe**: Allows you to remove a keyframe at the current Frame Number.
6. **Keyframes**: A list of all the keyframes.

For each face on keyframe:
1. **Face Id**: List of all the faces in current keyframe.
2. **Speaker**: Checkbox to set the speaker on the current Face Id of the current keyframe.
3. **Face Swap Id**: Checkbox to set the face swap id of the current keyframe on the current Face Id.
4. **Mouth Mask Dilate**: This will dilate the mouth mask to cover more area around the mouth. depends on the mouth size.
5. **Face Mask Erode**: This will erode the face mask to remove some area around the face. depends on the face size.
6. **Mask Blur**: This will blur the mask to make it more smooth, try to keep it under or equal to **Mouth Mask Dilate**.
7. **Padding sliders**: This will add padding to the head to avoid cuting the head in the video.

## Input Video
![Illustration](demo/input-video.png)

If no sound in translated audio, will take the audio from the input video. Can be useful if you have a bad lipsync on the input video.

Clone Voices:

## 📖 Behind the scenes

This extension operates in several stages to improve the quality of Wav2Lip-generated videos:

1. **Generate face swap video**: The script first generates the face swap video if image is in "face Swap" field, this operation take times so be patient.
2. **Generate a Wav2lip video**: Then script generates a low-quality Wav2Lip video using the input video and audio.
3. **Video Quality Enhancement**: Create a high-quality video using the low-quality video by using the enhancer define by user. 
4. **Mask Creation**: The script creates a mask around the mouth and tries to keep other facial motions like those of the cheeks and chin.
5. **Video Generation**: The script then takes the high-quality mouth image and overlays it onto the original image guided by the mouth mask.

## 💪 Quality tips
- Use a high quality video as input
- Use a video with a consistent frame rate. Occasionally, videos may exhibit unusual playback frame rates (not the standard 24, 25, 30, 60), which can lead to issues with the face mask.
- Use a high quality audio file as input, without background noise or music. Clean audio with a tool like [https://podcast.adobe.com/enhance](https://podcast.adobe.com/enhance).
- Dilate the mouth mask. This will help the model retain some facial motion and hide the original mouth.
- Mask Blur maximum twice the value of Mouth Mask Dilate. If you want to increase the blur, increase the value of Mouth Mask Dilate otherwise the mouth will be blurred and the underlying mouth could be visible.
- Upscaling can be good for improving result, particularly around the mouth area. However, it will extend the processing duration. Use this tutorial from Olivio Sarikas to upscale your video: [https://www.youtube.com/watch?v=3z4MKUqFEUk](https://www.youtube.com/watch?v=3z4MKUqFEUk). Ensure the denoising strength is set between 0.0 and 0.05, select the 'revAnimated' model, and use the batch mode. i'll create a tutorial for this soon.

## ⚠ Noted Constraints
- for speed up process try to keep resolution under 1000x1000px and upscaling after process.
- If the initial phase is excessively lengthy, consider using the "resize factor" to decrease the video's dimensions.
- While there's no strict size limit for videos, larger videos will require more processing time. It's advisable to employ the "resize factor" to minimize the video size and then upscale the video once processing is complete.

## 📝 To do
- ✔️ Standalone version
- ✔️ Add a way to use a face swap image
- ✔️ Add Possibility to use a video for audio input
- ✔️ Convert avi to mp4. Avi is not show in video input but process work fine
- [ ] ComfyUI intergration
