Can be used with:
https://github.com/kijai/ComfyUI-WanVideoWrapper and ComfyUI native WanVideo nodes.
I've also started to do fp8_scaled versions over here:

v1 = direct extraction, has adverse effects on motion and introduces flashing artifact at full strength.
v1.5 = same as above, but without the first block which fixes the flashing at full strength.
v2 = further pruned version with only attention layers and no first block, fixes flashing and retains motion better, needs more steps and can also benefit from cfg.
