ComfyUI: Testing Face Swap with Scene Cuts

ComfyUITry it →Watch full video →Veteran AI ·

Demo summary

The video demonstrates how the LTX 2.3 face swap LoRA handles a reference video with a camera cut and clothing change, showing its ability to maintain character features across transitions.

Step-by-step

  1. Load a reference video containing a camera cut and clothing change
  2. Select a face reference image
  3. Apply the LTX 2.3 face swap LoRA to the workflow
  4. Generate the final video output

Options

  • Use any face reference for wide shots where the face occupies few pixels

Watch out for

  • The face swap may produce an oily or plastic texture on the skin
  • The model cannot handle multi-character data or mid-video clothing changes if it locks onto the initial character features

Tips

  • Note that the model will likely force the character's initial clothing style to persist through camera cuts even if the source video changes outfits

Highlights

“the face doesn't look great; it has a very obvious oily or plastic texture to it”
