About UniFab

UniFab AI Video Enhancer is a cloud-powered online tool that upscales low-resolution videos up to 2x (e.g., 1080p to 4K) while reducing noise, sharpening details, and recovering lost textures. It operates entirely in a web browser with no installation or dedicated GPU required, using enterprise cloud GPUs via the FabCloud platform. Users can upload videos from any device, process them frame-by-frame for natural-looking results, and queue multiple files for batch enhancement.
