Luma AI has announced the launch of Ray3 Modify, a new model designed to bring greater control, continuity and intent to AI-driven acting and performance workflows. Introduced as the next evolution of its Ray3 video model, Ray3 Modify enables creators to enhance real-life actor performances using artificial intelligence, allowing scenes to be reshaped while preserving the essence of human-led acting. The model is now available on Luma AI’s Dream Machine platform and is aimed at production environments spanning film, advertising and post-production.

The announcement, made through a company press release, positions Ray3 Modify as a response to one of the longstanding challenges in AI-generated video — the difficulty of reliably preserving timing, motion and emotional intent during scene transformations. By conditioning AI generation directly on recorded footage, Ray3 Modify allows performances to remain grounded in the original actor’s delivery while opening up creative freedom to alter environments, styles and visual interpretation.

Luma AI said the new workflow allows brands to collaborate with actors to personalise and localise content without losing alignment with the original performance. For filmmakers, it offers the ability to shoot actors once and then place them into entirely different worlds, visual styles or cinematic contexts, guided by the same performance. The human performer, camera operator or physical footage becomes the primary source of direction, with AI following real-world motion, framing and emotional cues rather than replacing them.

Ray3 Modify has been positioned as a production-ready tool where predictability, continuity and repeatability are critical. The model preserves the original performance while enabling intentional changes to environments, costumes, cinematography and overall visual treatment, reducing the trial-and-error often associated with early generative video systems.

“Generative video models are incredibly expressive but also hard to control. Today, we are excited to introduce Ray3 Modify that blends the real-world with the expressivity of AI while giving full control to creatives. This means creative teams can capture performances with a camera and then immediately modify it to be in any location imaginable, change costumes, or even go back and reshoot the scene with AI, without recreating the physical shoot,” said Amit Jain, CEO and Co-founder of Luma AI.

The company noted that Ray3 Modify builds on Ray3’s existing strengths by introducing advanced capabilities such as start and end frame control, character reference locking and a more robust modify-video pipeline. These enhancements are designed to ensure that AI-driven edits respect physical motion, composition and identity continuity across shots, making the model suitable for real-world creative pipelines.

With Ray3 Modify now live on Dream Machine, Luma AI is pitching the model as a step towards true hybrid-AI production — one where creative authority begins with the performer and the camera, and AI acts as an extension that interprets and transforms that direction with precision rather than unpredictability.
