📝 TL;DR
🧠 Overview
Ray3 Modify is a new set of tools inside Luma’s Dream Machine that combines AI video generation with real cameras, real actors, and real performances.
Instead of starting from text prompts, you film once, then use AI to transform wardrobe, environment, lighting, and even character identity while preserving motion, timing, and emotion. It is aimed squarely at filmmakers, brands, and creators who want high end control without high end reshoot costs.
📜 The Announcement
Luma announced Ray3 Modify as a new hybrid AI workflow for acting and performance, now available in Dream Machine. The update brings three headline capabilities, Modify Video, Modify with Keyframes, and Character Reference, all designed to keep human performance at the center while AI handles the heavy lifting on visuals.
The goal is to fix a core flaw of early AI video, it was expressive, but could not reliably follow or preserve what actors actually did on camera.
⚙️ How It Works
• Modify Video - You upload a clip, then use Ray3 Modify to change wardrobe, environments, lighting, and product placement while keeping the physical logic, narrative flow, and performance authenticity of the original shot.
• Modify with Keyframes - You can set Start and End Frames to guide longer moves and transitions, telling the model how the scene should begin and end so it respects camera motion and spatial continuity in between.
• Character Reference - You add a character reference image, then Ray3 Modify projects that identity onto the actor, locking likeness, costume, and identity continuity across the whole clip.
• Performance preservation - The model is conditioned on the original footage, so it follows the actor’s real motion, timing, eye line, and emotional delivery while transforming the look of the scene around them.
• Strength slider for control - A Modify Strength slider lets you choose between Adhere for subtle relighting or retexturing and Reimagine for more stylized, surreal, or non human transformations.
• Designed for production pipelines - The tools sit inside Dream Machine with workflows for things like wardrobe swaps, virtual crowds, magic transitions, and mythical creature replacements, aimed at real film, VFX, and advertising work.
💡 Why This Matters
• Shoot once, create many versions - You can capture a single performance, then generate multiple creative directions, locations, or looks from that same footage instead of paying for reshoots every time the brief changes.
• Human performance stays in control - This is not about replacing actors, it is about using their real timing and emotion as the backbone while AI handles world building around them, which is a much more collaborative model for creatives.
• More predictable AI video behavior - Conditioning the model on actual footage and keyframes makes outputs less random and more repeatable, which is critical if you are trying to build a brand safe campaign or a coherent film.
• Big budget effects on smaller budgets - Things that used to require full VFX teams, like crowd duplication, environment swaps, or complex transitions, become accessible to smaller studios, agencies, and even ambitious solo creators.
• New creative language for video - Keyframes plus character reference plus performance preservation create a new way to direct, you describe the change, not the whole scene, and let AI fill in the in between while you stay in control of intent.
🏢 What This Means for Businesses
• Reuse and localize campaigns faster - Brands can film one hero performance, then use Ray3 Modify to adapt wardrobe, settings, and details for different regions, audiences, or seasons without dragging everyone back on set.
• Prototype ideas before big shoots - Small teams can shoot rough blocking passes, then use Modify to explore styles, locations, and concepts before committing budget to full production.
• Level up content offers and services - Agencies, editors, and production companies can add AI powered wardrobe swaps, product placement, and scene reimagining as premium services without rebuilding their entire pipeline.
• Tighten creator and client feedback loops - Instead of arguing over storyboards, you can show clients quick modified versions of real footage, then refine from there, which shortens approvals and reduces miscommunication.
• Protect your edge with unique performance, not just prompts - Because the system is driven by your own footage and characters, your outputs are anchored in material your competitors do not have, even if they use similar tools.
🔚 The Bottom Line
Ray3 Modify is a strong sign that high end AI video is shifting from prompt roulette to performance first workflows.
For the AI Advantage community, it opens a path where you can keep people and cameras at the heart of your process, then let AI reimagine everything around them with far more control, continuity, and creative freedom.
The practical question now is not whether AI can generate video, it is how you want to direct it.
💬 Your Take
If you could film a simple scene once, then use Ray3 Modify to transform everything around the actor, what is the first experiment you would run, a new ad concept, a short film idea, or a fully reimagined social content series?
