How motion transfer works
The engine tracks the pose, hands and face of the person in the reference video frame by frame, then renders your character doing the same thing. Wan2.2-Animate describes two modes: animating a character image from a reference video, or replacing the person in the original video while matching its lighting.
Kling Motion Control in short
Kling's guide asks for a character image and a motion reference of 3–30 seconds. 'Matches video' follows the reference's movement, expressions and camera; 'matches image' keeps the orientation of your photo. Kling recommends a reference with no cuts or camera moves, and matching proportions between image and video.
Other tools that do it
Runway's Act-Two uses a driving performance video of 3–30 seconds and a character image or video. Viggle offers dance templates from one photo. On Kenerate the same idea runs on 12 engines in one tool.
