Quick answer
Video upscaling is the process of increasing a video’s resolution — for example from 720p to HD or 4K — using AI that reconstructs detail rather than simply stretching pixels. Modern upscalers sharpen edges, reduce noise and compression artifacts, and can make AI-generated clips (which often render below 1080p) crisp enough for large screens.
Traditional upscaling interpolates between existing pixels, which produces soft, blurry results. AI upscalers instead predict what the missing detail should look like, trained on pairs of low- and high-resolution footage.
Upscaling pairs naturally with AI video generation: many models output at modest resolutions to keep generation fast, and an upscaling pass afterward brings the clip up to delivery quality.
VdoBloom includes an AI video upscaler powered by Topaz technology that enhances footage toward HD and 4K, alongside a separate image upscaler for stills.
