hello. In 'ComfyUI LivePortrait', if you created facial expressions using a reference video,

'Advanced LivePortrait' can be animated using only photos, no video.

It is useful because it does not require a reference video and changes in facial expressions can be seen in real time. I hope this helps you with your work 😊
