Luma AI offers Modify Video (also called video-to-video), a feature within Dream Machine that lets users transform existing video clips by changing environments, visual styles, character appearances, or other elements using text instructions — without reshooting footage.

Modify Video was introduced as an API capability in November 2024 and is available inside Dream Machine. It accepts an existing video clip plus natural-language instructions as input and outputs a transformed video that preserves the original motion while applying the requested changes. The Ray3 version (Ray3 Modify) adds precise keyframe and character reference controls, allowing changes such as relighting scenes, swapping environments, and altering costumes without green screens or post-production compositing.
