Runway Demos Character Swap: Recast Any Video Without Reshooting
runwayml · x · 2026-10-27
In its App Studio launch thread, Runway demoed Character Swap: upload an existing video, designate a new character, and the entire scene replays with the new cast—no reshoot required.
The app is described into existence in App Studio and runs on Runway's video models, a flagship demo of the describe-to-app approach.
