ComfyUI Scail 2 setup: motion transfer, groups and loops

This tutorial covers a ComfyUI workflow that applies movement from a reference video to a character image using Scail 2. The presenter explains model loading, portrait or landscape orientation, and input selection before testing character animation. A similar camera distance helps match the motion, while the image does not need to share the reference pose.

Setup starts with updates to Easy Installer, ComfyUI and its frontend, plus Pixaroma Nodes version 1.4 or newer. The optional Sage Attention installation uses batch files for Windows and Nvidia GPUs; the presenter warns that compatibility varies. The workflow uses Pixaroma Nodes and KJ nodes and requires five model downloads in their specified folders.

Much of the lesson covers workflow organization. Named Set/Get connections replace long visible links, while Pixaroma groups can collapse nodes and hide their links. Batch examples explain why the first image determines the dimensions of subsequent images. Loop nodes then repeat generation passes to extend the animation toward the reference video's duration.

For the demonstrated local AI setup, the presenter chooses FP8 scaled weights and reports successful operation with 24 GB VRAM. He estimates roughly 16 GB may be needed and warns that insufficient VRAM can cause slowdowns or failure. His reported generation time is about 7 to 8 minutes for a 15-second video, with a preview available after the initial pass.
