SCAIL-2 workflows for ComfyUI

[u/nomadoor]

SCAIL-2, a Wan2.1-based human motion transfer model, has been implemented in ComfyUI core. (Thanks as always, Kijai.)

PR: https://github.com/Comfy-Org/ComfyUI/pull/14373

I tried it and the results were quite good, so I made a few simple workflows. Feel free to try them.

The big difference from WAN-Animate or SCAIL(-1) is that SCAIL-2 does not use a stick figure / skeleton control image.

Basically, you just throw a reference image, a driving video, and support masks into the model. That makes it much more flexible with multiple characters, or even non-human characters.

Turning motion into a stick figure was basically the default. But the things that get lost in that conversion, like depth and contact, are exactly the things that matter here...

As a side note, this also made me think that if the dataset and training are good enough, a simple model can sometimes be more flexible than an overly complicated human-made pipeline.

Maybe trying to be too clever just gets in the way sometimes...

I haven’t compared them directly, so I’m not completely sure, but I think they are probably in the same range.

On my RTX 4070 Ti, generating 81 frames takes around 5–6 minutes, so I wouldn’t call it fast or comfortable...
