# Luma Launches Ray3 Modify — Create Videos by Providing Just Start and End Frames
Luma AI has unveiled Ray3 Modify, a groundbreaking AI model that revolutionizes video creation by letting users generate smooth transitional footage using only start and end reference frames. This innovation empowers creators to blend real-world performances with AI-driven transformations, preserving actor motion, timing, and expressions while enabling seamless scene changes, character swaps, or environmental overhauls[1][3].
Revolutionizing AI Video Generation with Ray3 Modify
Ray3 Modify builds on Luma's Ray3 foundation, introducing precise control over video outputs by accepting start and end frames to guide transitions. Creators can now direct character movements, behaviors, and scene continuity without extensive reshoots, making it ideal for studios handling brand footage or creative effects[1][3]. The model excels at retaining original human performance—including eye lines, emotional delivery, and motion—while applying transformations via character references for costumes, likeness, or identity swaps[1].
Unlike traditional generative tools that struggle with control, Ray3 Modify integrates advanced performance signals like pose, facial tracking, and lip-sync to maintain fidelity across the timeline. It supports native resolutions such as 16:9 720p and offers presets like Adhere for subtle retexturing, Flex for balanced creativity, and Reimagine for bold reinterpretations, including mapping humans to creatures[3][5].
Key Features and Workflow for Creators
Accessing Ray3 Modify is streamlined within Luma's Dream Machine editor: upload base footage, select "Modify," and input start/end frames or prompts for generation in 2-4 minutes[3][5]. Users can extract full-body or facial motion from clips to drive new characters, props, or camera paths, transforming a garage into a spaceship or day scenes to night without losing framing or action[3].
Ray3's intelligent reasoning enhances this with HDR support (up to 16-bit EXR for pro pipelines), accurate physics, and draft modes for rapid ideation before HiFi mastering to 4K[4]. Additional tools include video extension, reframing, upscaling, and audio integration, with options for multiple variants to speed up feedback loops[2][4].
Real-World Impact on Filmmaking and Creative Studios
Luma's CEO Amit Jain emphasized how Ray3 Modify "blends the real-world with AI expressivity while giving full control to creatives," allowing teams to modify shoots on-the-fly for any location or costume[1]. This addresses key pain points in AI video, where models often fail to follow input footage, enabling human actors for initial captures then AI for enhancements[1].
Early demos showcase cinematic results: prompt-based scenes with automatic lighting, depth, and camera control, adaptable for vertical formats or EXR exports[2][6]. While Ray3 videos adapt to Ray2 for modifications (potentially causing style shifts), it's optimized for Ray2 Flash workflows, positioning Luma as a leader in studio-grade AI video tools[5].
Frequently Asked Questions
What is Ray3 Modify? Ray3 Modify is Luma AI's new model that generates videos from start and end frames, preserves original motion and performance, and allows transformations like character swaps or scene changes using references and prompts[1][3].
