Luma LabsRay generates dynamic, high-quality videos from concise prompts and reference inputs, with fine control over visuals, pacing, and transitions. Choose aspect ratios to match your platform (1:1, 9:16, 16:9, 4:3), and guide narrative flow using start/end image URLs or video IDs. For seamless loops, align the first and last frames and enable looping. Use clear, high-resolution references and avoid ambiguous wording to reduce drift. Ray supports continuous playback, smooth transitions, and HD rendering for social content, branding, storytelling, and educational clips. Test framing across aspect ratios and refine prompts iteratively to achieve precise, visually consistent results.
