3. Stable Diffusion Settings

Before we proceed, it's crucial to ensure that specific global settings are correctly configured. These global stable diffusion settings play a vital role in guaranteeing the accuracy of the names for the face-swapped image sequence. This precision is essential for the seamless utilization of the image sequence in the NextView Extension. Furthermore, it's imperative to have the image sequence in PNG format for optimal results. These measures are pivotal in the creation of a stunning video.

  • Navigate within Stable Diffusion to the "Settings" tab.
  • Click on "Saving images/grid" in the left sidebar.
  • Confirm that the "File format for images" is set to png.
  • Ensure the "Images filename pattern" field is left empty.
  • Make sure the option for "Adding a number to the filename when saving" is unchecked.


After configuring the settings correctly, select "Apply settings," followed by clicking on "Reload UI."

4. Video to Image Sequence (NextView Extension)

Once all the specified requirements are successfully installed, the procedure will commence by accessing the NextView Extension.

  • Navigate to the NextView Extension within Stable Diffusion.
  • Place the video onto the canvas within the NextView Extension.
  • Click on the "Generate Image Sequence" button.


After the process is complete, you will be given a file location containing all the generated images extracted from the video. You can now proceed to copy this file location, which will enable you to utilize the image sequence for batch processing within the Img2Img tab.

5. Img2img Settings (Batch)

After copying the file location containing the image sequence extracted from the video file using the NextView Extension, you can move on to the Img2Img "batch" tab.

Img2img batch settings

  • Copy the file location containing the image sequence extracted from the video file using the NextView Extension.
  • Navigate to the Img2Img tab.
  • In the Img2Img "batch" subtab, paste the file location into the "input directory" field.
  • Choose a suitable location for the "output directory." (This is where all the batch face-swapped images will be stored)


Note: The location you entered in the "output directory" will be used later to convert the images into a video with the NextView Extension.

Global Img2Img settings:

  • Checkpoint: Realistic Vision
  • Sampling Method: Euler a
  • Sampling Steps: 30
  • Denoising Strength: 0 (We've set denoising to 0 because our intention is to preserve the image sequence as is, without altering anything except for the face)
  • Seed: -1
  • Width & Height: Make sure that the video ratio aligns with the image sequence you supplied earlier, in our case, this ratio is 9:16.


Now that we have these settings in place, we can transition to the following stage, which entails employing the Roop extension for face swapping. Hopefully, you already have a fantastic face in mind for the face swap! Let's move forward.

6. Roop Extension Settings (Face Swap)

If you've been following this tutorial, you'll find a dropdown menu featuring the Roop extension. Open this dropdown and upload an image of the beautiful face you'd like to apply to the image sequence. For the sake of this tutorial, we've selected the stunning image of Salma Hayek as our choice.
