About

UniFab is an all-in-one AI-driven platform built to solve a wide range of video and audio enhancement challenges. At its core, UniFab's Video Upscaler AI can intelligently scale footage from standard definition all the way up to stunning 16K resolution, with AI-driven improvements in brightness, contrast, and sharpness. The Denoise AI removes grain and noise from low-light or compressed videos, while the Colorizer AI brings authentic color to black-and-white or vintage footage using Multi-Scene Colorization Mode. The Face Enhancer AI sharpens facial features and supports 2x and 4x resolution scaling for lifelike portrait quality. On the audio side, UniFab's Audio Upmix AI upgrades stereo tracks to EAC3 5.1 or DTS 7.1 surround sound for a cinema-grade listening experience. Free tools include a Background Remover and Vocal Remover for karaoke or instrumental mixes. Additional capabilities include an HDR Upconverter, Deinterlace AI, Video Stabilizer, Subtitle Generator, Video Translator, and a Video Converter supporting 1,000+ formats. UniFab leverages GPU and NVIDIA CUDA processing for accelerated performance and is available as a Windows desktop app as well as cloud-based tools through its FabCloud platform. It's ideal for filmmakers restoring vintage footage, YouTubers upgrading video quality, and professionals seeking an automated, AI-first video production toolkit.
