ComfyUI: Close-up Face Swap Test

ComfyUI Try it →Watch full video →Veteran AI · Mar 2026

Demo summary

A demonstration of a close-up face swap where the LTX 2.3 model transfers facial expressions and lip movements from a driving video to a target portrait.

Step-by-step

Select a close-up video of a subject talking to serve as the driving video
Choose a standard portrait to use as the face reference image
Apply the LTX 2.3 model to render the reference features onto the driving video
Use the shot angle selection from the workflow to optimize the face swap results

Watch out for

Note the difference between Eastern and Western facial features as it affects the generation

Tips

Use the specific shot angle selection from this workflow as a reference for ideal results
Observe subtle actions like facial expressions and lip movements to verify the quality of the replication

Highlights

“even subtle actions like facial expressions and lip movements are flawlessly replicated in the generated video”
