Character swap

Swap the person in a video while keeping the scene, camera move, timing, and audio. Shoot (or generate) once, recast at will.

The recipe

1. Get the source clip — generate one with Video Gen or wire in footage via a Video input node.
2. Get the character — one full-body image of the new person. Frame it 16:9 so a center crop can’t clip them; clean, front-lit, face clearly visible.
3. Wire both into Character Swap — clip to video, image to character_image.
4. Pick the mode — Replace keeps the clip’s framing and swaps who’s in it. Move goes the other way: it animates your character with the clip’s motion.
5. Run. The output keeps the source audio, and billing is by the second of the clip.

Tips

• The character image quality is the ceiling — a sharp, well-lit full-body shot beats a cropped candid every time.
• Works on generated and real footage alike, so you can previz with a stand-in and recast the final.
• For voice as well as body, chain the result into the Voice swap recipe.
