1 This is an 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 confines the editing range to the specified subject area, striving to retain the original video's actions, shots, 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.
