Show HN: Ray3 AI Video – Reasoning Video Model with HDR and Draft Mode (ray3aivideo.com)

Ray3 is a new AI video-generation system that touts several production‑grade features: native 16‑bit HDR video generation, a multimodal AI reasoning engine that iterates on user intent, a rapid “draft mode” (claimed 5× faster and 5× cheaper for previews), and a Hi‑Fi upscaling pipeline to convert drafts into 4K HDR output with synchronized audio. It also supports visual annotations and keyframe controls (draw motion, camera moves, and object interactions), advanced physics simulation for realistic motion/lighting, and character-consistency tracking across scenes. Ray3 reports 600k+ generated artworks and 70k+ active users and positions itself as a workflow tool for both rapid prototyping and final production. For the AI/ML community, Ray3 highlights progress on several technical fronts: temporally coherent HDR synthesis (16‑bit color/fidelity), multimodal inference that understands visual annotations and textual prompts, and staged pipelines that separate low-cost drafts from compute‑heavy Hi‑Fi upgrades. Its claims about robust character tracking and physics-aware rendering suggest advances in long-range temporal consistency and physically plausible generative models. If validated, these features could shift video creation workflows—enabling fast iteration, lower preview costs, and higher-quality final outputs—and raise research interest in scalable, HDR‑aware architectures, annotation-to-motion mapping, and efficient upscaling for cinematic video generation.
