Luma: luma_video_upscale API

A specialized video super-resolution and enhancement model designed for the Ray 3 architecture by Luma AI. Utilizing Hi-Fi Diffusion technology, it goes beyond simple upscaling by re-reasoning and synthesizing fine textures (e.g., hair strands, skin pores, water ripples). It can upscale 540p or 720p drafts to 4K Ultra HD while applying 16-bit HDR color space mapping, meeting Hollywood-grade production and color grading standards.
