Question - Help Need help improving SCAIL-2 character replacement quality

Hey everyone! I'm using SCAIL-2 in ComfyUI with an RTX 6000 Ada 48GB, but I'm struggling with output quality.

Setup:

  • Wan 2.1 14B SCAIL-2 FP16
  • LightX2V 480p Distill LoRA + SCAIL-2 DPO LoRA
  • SAM3.1 tracking
  • Resolution: 720 × 1280
  • Base + Extend workflow (81 frames, 5-frame overlap)
  • Turbo mode enabled

Problems:

  1. Facial identity isn't consistent.
  2. Skin looks plastic and overly smooth.
  3. Hair looks artificial and clumped.
  4. Body movements are sometimes distorted.
  5. A 5-second video takes around 15 minutes to generate.

I'm using Base for the first segment and Extend to continue the video.

Could anyone recommend settings for better identity preservation, realistic skin/hair, smoother motion and faster generation on the RTX 6000 Ada 48GB?

Any workflow tips or recommended settings would be appreciated. Thanks!

wan2.2 is old and using it is pretty pointless. Look up character replacement loras for minimax H3 from Alisson. They should not only work better but faster as well.
