subject_definitions
<Subject 1> is the woman whose appearance comes exclusively from <Picture 1>. <Picture 1> defines only her identity and visual appearance, including her face, hairstyle, body shape, clothing, colors, skin appearance, accessories, and other visible characteristics. <Picture 1> is NOT a first-frame reference, last-frame reference, keyframe, pose reference, or endpoint pose reference.
<Subject 2> is the female performer in <Video 1>. Her appearance is not transferred. Only her complete temporal performance is used as the motion reference, including body movements, poses, gestures, actions, timing, rhythm, speed, movement trajectory, and transitions between poses.
<Video 1> is the complete motion and temporal-structure reference for the target video. Its movement progression from the first frame to the final frame must be followed continuously.
summary
[reference generation] Replace the female performer in <Video 1> with the woman from <Picture 1>. Preserve the complete continuous motion performance and temporal progression of <Video 1> from the first frame through the final frame, while using <Picture 1> exclusively for the replacement woman's appearance. <Picture 1> must never function as a starting pose, ending pose, keyframe, or pose target.
retention_analysis
<Subject 1>: fully_preserved - Preserve the woman's visual identity and appearance from <Picture 1> throughout the entire video. Do not interpret <Picture 1> as a temporal or pose reference.
<Subject 2>: attribute_transfer - Transfer the complete body-motion performance and temporal progression of the woman in <Video 1> to <Subject 1>, from the first frame continuously through the final frame.
<Video 1>: fully_preserved - Preserve the source video's movement progression, timing, rhythm, action sequence, pose transitions, and temporal continuity throughout the target video.
detailed_description
The target video is a continuous motion replacement based on <Video 1>. The woman from <Picture 1> replaces the woman in <Video 1> and performs the same continuous movement performance as the original woman in <Video 1>.
From the very first frame, <Subject 1> must already be performing the corresponding action and pose progression of <Video 1>. Do not begin the video by recreating, holding, approaching, or transitioning into the static pose shown in <Picture 1> unless that pose is explicitly present at the corresponding moment in <Video 1>.
Continue following the motion of <Video 1> continuously and consistently throughout the entire timeline. Reproduce the original woman's actions, body movements, gestures, poses, movement trajectory, timing, speed, rhythm, and transitions between poses in their original temporal order.
Do not stop, reset, freeze, simplify, or reinterpret the motion at any point. Do not introduce new actions or independently generated movements that are not present in <Video 1>. Do not allow the woman's movement to drift away from the motion sequence of <Video 1> during the middle or later part of the video.
The motion sequence must remain faithful to <Video 1> from the first frame to the final frame. Every intermediate movement should be understood as part of the same continuous performance derived from <Video 1>, rather than as a newly generated action.
At the final part of the video, <Subject 1> must continue and complete the movement according to <Video 1>. Do not return to, hold, or recreate the static pose from <Picture 1> at the end unless that exact pose and timing occur in <Video 1>.
<Picture 1> provides appearance only. It provides no motion, no pose sequence, no starting state, no ending state, no keyframe, and no temporal instruction.
Do not use the visual appearance of the woman in <Video 1>. Do not transfer her face, hairstyle, body shape, clothing, colors, skin appearance, accessories, or visual identity.
The final result must be a frame-by-frame temporal replacement: the woman from <Picture 1> continuously performs the movement of the woman in <Video 1> from the beginning of the video to the end, without reverting to the pose of <Picture 1> and without inventing unrelated motion.
