Use the original uploaded video as the exact reference for the entire sequence, and use the uploaded character image only as a shape/contour reference for the horror entity.
Video Prompt
Recreate the original video as closely and faithfully as possible. Keep the original video unchanged in every aspect except for the silhouette contour of the horror entity.
Reference inputs:
Original video: exact reference for all scenes, camera work, timing, movement, environment, lighting, editing, and composition.
Uploaded character image: reference only for the body shape, head shape, hairstyle outline, proportions, and recognizable outer contour of the horror entity.
Replace the original horror entity with a completely black silhouette based on the uploaded character.
The uploaded character must NOT appear with their normal face, skin, clothing colors, textures, or detailed features. Instead, convert the character into a solid pitch-black shadow figure. Only the outer silhouette and contour should reveal who or what the uploaded character is.
For example, preserve recognizable contour details when applicable, such as distinctive hairstyle, ears, horns, hat shape, body proportions, shoulders, clothing silhouette, or other characteristic outlines. These details should influence only the silhouette shape.
Critical preservation rule
Everything except the entity's contour must remain identical to the original video.
Preserve exactly:
original location and architecture
furniture and props
all other characters
character appearances and costumes
camera position and camera movement
framing and lens perspective
shot sequence
duration of every shot
cuts and transitions
lighting and shadows
color grading
suspense atmosphere
character actions and reactions
entity position
entity scale
entity movement
entity entrance and disappearance timing
final reveal timing
Entity appearance
The replacement entity must remain pure black throughout the entire video, matching the shadow-like visual treatment of the original entity.
Do not reveal the uploaded character's face.
Do not reveal eyes, facial features, skin, clothing details, colors, patterns, or textures.
Do not brighten the entity.
Do not turn it into a normally lit character.
Only change the black silhouette's outer contour so that its shape clearly corresponds to the uploaded reference character.
The entity should still behave exactly like the original horror entity. Match the original pose, screen position, movement path, speed, body orientation, visibility, and timing frame by frame.
Maintain strong temporal consistency. The silhouette must not flicker, morph, randomly change proportions, gain facial details, change color, duplicate, or drift from the original entity's position.
Final result: the video should look identical to the original footage at first glance, with the only difference being that the original black horror silhouette now has the recognizable contour of the character from the uploaded image.
