The method decouples edit-driven synthesis from source-grounded identity preservation. It uses relit facial regions, facial normal maps, edited keyframes, and depth sequences so the model can propagate a new style or lighting setup while re-aligning to the original performance after imperfect keyframes.
ID-V2V is useful for filmmakers, VFX teams, and researchers exploring controllable video-to-video generation. It supports restylization and relighting workflows where the creative look can change substantially without sacrificing the actor's facial motion and identity.
