Fixing Face Drift in a Zombie Couple Video
Improve reference clarity and simplify motion to reduce identity changes.
Locate the change
Watch slowly. A face may look convincing until a turn, shadow or overlapping arm hides details. Compare frames before and after the change.
Improve the references
Replace blurry, strongly side-facing or filtered portraits with clear natural ones. Keep eyes visible and use similar lighting in the pair.
Simplify the story
Recognition and a gentle hug are simpler than a chase, spin and transformation montage. Try a calmer scene. Mild theatrical makeup retains more identity cues than strong distortion.
The scene generator does not offer per-frame face controls. More resolution cannot guarantee drift disappears. A new attempt uses displayed credits unless the task is recorded as failed.
Change one reference at a time. See photo preparation and credit costs.
