FlashVSR

What it does

FlashVSR is the first real-time diffusion-based 4K video converter featuring video super-resolution (VSR). Perfect for long-video upscaling and detail recovery.

FlashVSR is the best AI video upscaler for 4K , designed to convert low-resolution videos to 4K with restored detail and consistent quality. Our advanced AI tool to enhance blurry videos effortlessly removes noise and artifacts for crystal-clear visuals. High-Fidelity Detail Recovery, Optimized High-Speed Reconstruction, and Temporal Consistency. With 4x video resolution enhancement capabilities, FlashVSR supports video upscaling for long clips up to 10 minutes. FlashVSR is up to 12x faster than traditional diffusion-based VSR models, providing lightning-fast video upscaling without compromising quality. Choose from 1x to 4x resolution upscaling, offering true 4x video resolution…from flashvsr.art

In the maker’s words, at launch

AI-generated video has made remarkable progress, but the output often caps at 480p or 720p—blurry textures, jagged edges, and lacking detail. For creators, that’s far from production-ready. FlashVSR is a super-resolution tool designed specifically for this use case. Built on diffusion models, it delivers…

  I built FlashVSR, a high-performance video super-resolution model that enhances clarity up to 4× while keeping motion stable and natural — running up to 12× faster than diffusion-based approaches. Unlike typical upscalers that trade off realism for speed, FlashVSR combines High-Fidelity Detail Recovery, Optimized High-Speed Reconstruction, and Temporal Consistency to achieve real-time 4K enhancement. Key Features Up to 12× faster reconstruction without quality loss 1×–4× flexible upscaling to Full HD, 2K, or 4K Integrated color correction for cinematic tone Adaptive temporal attention to…

  Vidformer – Drop-In Acceleration for Cv2 Video Annotation Scripts2025 · github.com · ▲25

  Hi HN, this is a project I've been working on as part of my PhD. Vidformer is a system that makes video annotation or transformation scripts practically instant. Traditional scripts that render full videos can take minutes—Vidformer speeds this up by optimizing execution and using on-demand rendering, so results appear immediately instead of waiting for entire videos to render. It works as a drop-in replacement for OpenCV's cv2, meaning most scripts can adopt it by simply changing "import cv2" to "import vidformer.cv2 as cv2"—no need to rewrite code or sacrifice flexibility. Vidformer is…

  Lemon Slice Live – Have a video call with a transformer model2025 · ▲195

  Hey HN, this is Lina, Andrew, and Sidney from Lemon Slice. We’ve trained a custom diffusion transformer (DiT) model that achieves video streaming at 25fps and wrapped it into a demo that allows anyone to turn a photo into a real-time, talking avatar. Here’s an example conversation from co-founder Andrew: https://www.youtube.com/watch?v=CeYp5xQMFZY. Try it for yourself at: https://lemonslice.com/live. (Btw, we used to be called Infinity AI and did a Show HN under that name last year: https://news.ycombinator.com/item?id=41467704.) Unlike existing…
