Genjutsu vs motion control vs object swap
Choose by the change you want: transfer a performance or edit an element in an existing clip.
Genjutsu: a named workflow
The word identifies a provider workflow, not a universal API or a promise of identical results from every video model.
Motion control: a performance reference
A reference clip guides movement and timing. Character and scene details can be reconstructed rather than preserved pixel for pixel.
Object swap: a targeted edit
Use an editing model when replacing a person, product or background inside an existing clip. Inspect the surrounding details for unintended changes.
