👤 Video Face Change Using Stable Diffusion

In this video Tutorial, I will be demonstrating how to change faces in a video using the stable diffusion technique. This method involves the use of two plugins: Temporal-Kit and Roop. Additionally, we will utilize the EbSynth tool to remove any flickering in the video.

Before we begin, make sure you have installed the necessary plugins and tools. If you haven't done so already, check the description column of my video for the download links and installation instructions.

1. Video Face Change Using Stable Diffusion

Stable diffusion is a powerful technique that allows you to alter faces in a video seamlessly. By using the Temporal-Kit plugin, we can generate key frames and manipulate the face in each frame. The Roop plugin provides options to select different face replacement algorithms and adjust parameters such as transparency and zoom. With these tools, you can achieve realistic face changes in your videos.

2. Required Plugins: Temporal-Kit and Roop

Before we dive into the process, let's make sure we have the required plugins installed. Temporal-Kit is a plugin specifically designed for video manipulation, while Roop specializes in face replacement. These plugins work in conjunction to perform the face change we desire.

3. Additional Tool: EbSynth for Flickering Removal

To ensure a smooth and flicker-free video, we'll be using the EbSynth tool. This tool helps eliminate any flickering that may occur during the face change process. By applying EbSynth to our video, we can enhance the overall quality and stability of the final output.

4. Updating Stable Diffusion Webui to V1.5.1

If you've updated your stable diffusion webui to version V1.5.0 or above, it's essential to update it further to version V1.5.1. Failure to do so may result in an error related to extension conflict when using the Temporal-Kit plugin. Follow the provided instructions to update your webui and resolve any conflicts that may arise.

5. Handling Extension Conflict Error with Temporal-Kit Plugin

If you encounter an extension conflict error while using the Temporal-Kit plugin, there is a simple solution. Navigate to the specified folder and delete two specific files that are causing the conflict. After deleting these files, restart your webui to reinstall them automatically.

6. Solving the Error by Deleting Files

To resolve the extension conflict error with the Temporal-Kit plugin, locate the specified folder and delete the two problematic files. This action ensures a clean installation and eliminates any conflicts. Instructions for locating and deleting these files are provided in the video description.

7. Changing the Face of a Video Using Temporal-Kit Plugin

Now, let's get into the actual process of changing faces in a video using the Temporal-Kit plugin. Start by opening the plugin and uploading your original video. Within the plugin settings, you have the option to determine the number of frames per picture, the resolution, and the frame rate. Adjust these parameters according to your requirements.

8. Setting Parameters for Face Replacement

To achieve the desired face replacement, it is crucial to set the parameters correctly. Consider the number of key frames, the resolution of the output, and the zoom level. These settings will dictate the quality and accuracy of the face change in the generated pictures. Experiment with different values to find the best results for your specific needs.

9. Generating Key Frames and Outputting Results

Once the parameters are set, click the generate button to create the key frames with the replaced face. The plugin will process the frames and generate a set of output pictures accordingly. Check the results and make any necessary adjustments to the face replacement or other parameters to achieve the desired outcome.

10. Using Roop Plugin to Change the Face

In addition to the Temporal-Kit plugin, we'll be employing the Roop plugin to enhance the face change process. Roop offers different algorithms for face replacement, allowing you to choose the most suitable option for your video. Adjust the transparency and zoom settings to control the appearance of the replaced face.

11. Selecting Algorithms and Adjusting Parameters

When using the Roop plugin, select a face replacement algorithm that aligns with the characteristics of the original and replacement faces. Adjust the transparency parameter to achieve a seamless Blend between the faces. Additionally, customize the zoom algorithm based on your preferences and requirements.

12. Batch Processing for Multiple Face Changes

If you need to replace multiple faces in a video, the batch processing feature in both the Temporal-Kit and Roop plugins will be beneficial. After processing the initial set of key frames, you can apply the same process to subsequent frames. This saves time and ensures consistency throughout the video.

13. Processing Output with EbSynth Tool

Once the face changes are complete, it's time to process the output frames with the EbSynth tool. Drag the frame files and key frames folder into the EbSynth tool, which will apply the necessary adjustments to remove flickering and enhance the stability of the video. Batch processing is recommended, as the tool can handle a limited number of frames at a time.

14. Correcting and Replacing Generated Faces

After processing the frames with the EbSynth tool, review the results to ensure the face changes are accurate and satisfactory. If any issues or inconsistencies are detected, return to the Temporal-Kit plugin, locate the corresponding frame, and make the necessary corrections. Replace the incorrectly generated faces and save the modifications.

15. Repeating the Process for Multiple Frames

If you have replaced multiple faces in the video, repeat the process outlined above for each frame. This ensures all faces are accurately replaced, and any mistakes or inaccuracies are corrected. Take your time to review each frame and make the necessary adjustments to achieve the desired outcome.

16. Generating the Final Video with Stable Diffusion

Once all face changes have been made and corrected, it's time to generate the final video. Use the stable diffusion technique with all the processed frames to create a seamless and Cohesive video. The finished video will showcase the replaced faces and appear as though the changes were made in the original footage.

17. Adjusting the Video Length with Da Vinci Resolve

In some cases, the length of the face-changing video may differ from the original video. To synchronize the lengths and maintain consistency, you can utilize video editing software like Da Vinci Resolve. Import both the original and modified videos, adjust the variable speed points to match their durations, and export the final video with synchronized lengths.
