Recast a martial arts scene with AI
Morphic Recast swaps the actors in finished footage while keeping the original performance, camera and timing, so a martial arts scene can be recast without a reshoot. Give it one photo per fighter: every kick, sweep, block and bow lands on the same beat, performed by new fighters.

A training-yard spar, new fighters. Two photos, two new fighters. The high kick, the sweep, the jump and the closing bow land on the same frames, in the same misty training yard.

The fighter with short black hairA red-bearded man in grey

Doubles to principals
Let trained martial artists perform the fight, then put your principal cast onto the same take.

How do I recast the actors in a martial arts scene without reshooting?
- 01
Upload the fight shot
Add one clip up to 30 seconds. For a longer sequence, recast it shot by shot and cut the shots together on the Compose timeline.
- 02
Add a photo per fighter
One photo for each person you replace, dressed the way they should look on screen. Anyone you give no photo stays exactly as shot.
- 03
Name each swap and run it
Ask Copilot, for example: the fighter with the black ponytail becomes the woman in photo 1. Every move and the timing stay as shot.

Consent and releases
Recast only footage you hold releases for, and use photos of people who agreed to appear. Every example here uses generated people, not real actors.
When to also dub
The recast keeps the original soundtrack. For new lines or another language, run Morphic Dub on the recast shot so the voices and lips match.
Recast or reshoot
Recasting a martial arts scene skips a new shoot day and calling the cast back, and one take can carry a cast per market. Reshoot only when the action must change.
Review it as a team
Keep the source shot, the cast photos and every take in one project, where teammates in your workspace open the same versions and comment on each.
