FLUX Video Upscale applies Black Forest Labs' FLUX.3 super-resolution to existing footage, regenerating detail rather than simply interpolating pixels. Feed it a clip up to 20 seconds and 50MB, then choose Precise mode to sharpen the source exactly as shot (ideal for faces, products, and brand footage) or Creative mode to invent finer texture in scenery, crowds, and generated video. Set the scaling factor from 1.5x to 3x to land on 1080p, 2K, or 4K output while the source aspect ratio is preserved. Ideal for marketing, e-commerce, and film.
