Core positioning: Video-oriented character replacement. Seamlessly swap the target character’s appearance into the source video’s actions, expressions, and camera framing/placement, while preserving temporal consistency and natural lighting.

Key capabilities:

  Identity preservation: Lock the target’s facial features, hairstyle, and outfit color palette to reduce cross‑frame drift and “face‑swap” artifacts.

  Motion and expression transfer: Follow the source video’s head pose, facial expressions, and body movements.

  Background preservation: Keep the original scene and camera motion unchanged; replace only the foreground person.

  Temporal coherence and lighting match: Smooth across frames and match on‑set illumination and color.
