Fast video faceswapping, and possibly a base for more advanced workflows.
On my Ryzen 4600G,16G RAM, RTX 4060 8GB:
A 5 second, 608x1080 video @ 30fps, takes about 5 minutes.
Versions used:
ComfyUI Desktop 0.21.1
Reactor 0.7.0-a2
May work on other versions,but not guaranteed.
Also, could break if something changes in ComfyUI or Reactor.
You can always try to extend it with other nodes to generate faces, upscale,etc.
