>>5634ComfyUI is extremely powerful and let you do things you'll never be able to do with SD WebUI, but it's harder to use. I've been an early user of SD WebUI and I've switched to ComfyUI a "long" time ago.
And just look for the template called "Image to Video (New)" in the Templates section (filter by model and select WAN 2.2), it does pretty much the same thing as my workflow but uses a subgraph for a simplified view.
FP8 models of WAN 2.2 are around 9.5GB, they should run on your RTX 3060.
As for Pinokio, it's just a tool for managing installation of certains IA applications. There's no real need for it as ComfyUI has its own installer app on MacOS and Windows.
If you're on linux, just clone the repo like you probably did with SD WebUI. Create a python virtual env, install the dependencies with pip (use the requirements.txt file), then launch main.py.
