Use a video to drive motion in your character or replace a subject in an existing clip. Choose how motion and appearance are combined using the mode selector.
Motion Transfer side-bar module.
Motion Transfer Modes:
Motion: Apply motion from the source video to your character reference. The output keeps the character and scene from the reference, and follows the source video’s movement and timing.
Replace: Keep the source video’s motion and scene, but replace the subject with your character reference.
Matching the framing between the reference image and source video as closely as possible can lead to better results.
