1 This is a SCAIL 2 reference editing workflow for single-target character replacement. It not only allows the reference character to follow the actions of the original video but also limits the editing scope to the specified subject area, striving to retain the original video's actions, camera angles, scenes, and lighting relationships. It is suitable for tasks such as single-character replacement, character substitution, virtual character takeover, live-action to character transformation, furry/alien character reference editing, balancing action consistency and visual stability.
