Luma AI's Modify Video lets you swap characters without losing motion
Luma AI just launched Modify Video, a video-to-video editing tool inside Dream Machine: Ray 2 that reimagines backgrounds, lighting, and characters while locking down original motion, facial expressions, and camera paths. In blind evaluations, Luma claims it consistently beats Runway V2V on temporal consistency and motion retention. It is a huge shortcut for creators who want rapid iterations without reshooting from scratch.
