Show HN: FlashVSR – High-Speed 4K Video Super-Resolution

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 prevent flicker and ghosting

Trained on VSR-120K for superior texture and clarity

Applications

AI Video Generation & Restoration (Runway, Sora, etc.)

YouTube / TikTok / game footage upscaling

Film & Archival Restoration

4K mastering for creators and production teams

Would love feedback from the HN community — especially on real-time upscaling, color accuracy, and AI video tool integration.
