I recently explored several free, open-source video upscaling tools available on GitHub, and thought I’d share my findings here for anyone interested in AI video enhancement.
Many of these GitHub projects use advanced AI models (ESRGAN, Real-ESRGAN, Waifu2x variants, etc.) to upscale low-resolution or blurry videos. They’re powerful, customizable, and completely free — but they usually require technical setup, GPU configuration, and sometimes command-line usage.
If you’re comfortable with coding, these GitHub video enhancers can deliver excellent results.
But if you prefer something easier with no setup required, there’s also a lightweight alternative: HitPaw VikPea, an AI video enhancer that supports 4K upscaling, color & detail restoration, and batch repair for damaged or noisy videos. It works without scripts or model downloads, so it might be useful for non-technical users.
Here’s the original full article if you want a detailed comparison of both:

Would love to know what tools others here are using — both open-source and commercial options. Feel free to share!
