Ray3 Modify is Luma's AI model - dropped in December 2025 - that changes real videos instead of making new ones from scratch. You start with live footage and tell the AI what to change... like clothes, weather, lighting or background. It keeps the movement and acting the same.
It can also swap how people look. You can pick a character image to make someone wear a costume or turn into something like a fantasy figure without messing up their face or timing.
You can guide changes by picking the first and last frame. The AI then fills the middle so everything stays smooth and looks realistic.
It also lets you swap places or times of day in a scene. Like turning a street shot into a night scene or a fantasy-style town without filming again.
The AI uses the uploaded video as its base and edits around that. It keeps things like poses and expressions while changing the rest based on your notes or added images.
You use Ray3 Modify through the Dream Machine site or iOS app. Just upload up to 10 seconds of video and give your edit instructions. You can add character images or pick start and end frames if needed.
Control options include how strong the changes are, setting keyframes, and picking a character image to keep the style the same through the video.
