Luma AI Launches Ray3: The First Innovative Model Supporting HDR Video Generation

Luma AI recently launched a video generation model called Ray3, claiming it is the first product capable of producing professional-grade HDR (High Dynamic Range) videos. Ray3 supports 10-bit, 12-bit, and even 16-bit color depths, and can output EXR format files, allowing seamless integration with professional editing and color grading workflows. In addition, Ray3 has the ability to convert standard SDR videos into HDR, providing users with more creative options.

A notable feature of Ray3 is its "reasoning" capability. This feature enables it to simultaneously understand images and language, execute complex instructions, and evaluate its own outputs. Luma AI states that Ray3 can critique early drafts and iterate repeatedly until reaching the set quality standards. This reasoning capability also gives users higher visual control, allowing them to guide moving objects, cameras, or frames by directly sketching on the image, without having to input text prompts.

To improve efficiency, Ray3 introduces a draft mode that can generate rough video previews at a lower cost and faster speed, up to five times faster. These drafts can be upgraded to full 4K HDR "high-fidelity" quality during the second processing. Luma AI emphasizes that Ray3 has improved in rendering crowd scenes, light interactions, reflections, motion blur, and character consistency, further enhancing the realism and detail of the videos.

Currently, Ray3 is available for free to users through Luma AI's Dream Machine application. Luma AI views the Ray3 framework as a "storytelling" creative tool and has already released several short films made using this technology. However, unlike Google's Veo3, Ray3 cannot natively generate audio, a feature that may be improved in the future.

Key Points:
🌟 Ray3 is the first model that supports HDR video generation, with multiple color depths and EXR file output capabilities.
🖌️ The model's "reasoning" capability allows users to perform visual control through sketch drawing, enhancing creative flexibility.
⚡ Ray3's draft mode can quickly generate low-cost video previews and can be upgraded to high-quality 4K HDR.
