WAN2.1 FlashVSR 视频放大清晰 - KJ

FlashVSR is a video super-resolution model that upscales low-resolution videos to high-resolution in real time, aiming for "clarity, stability, and speed."

It can perform super-resolution/deblurring on long videos, resulting in clearer details, more stable textures, and significantly reduced jagged edges and flicker. Traditional super-resolution models require multiple iterations, which is slow; FlashVSR uses a "single-step diffusion" approach, which is very fast, achieving both good results and speed. One-step diffusion (reducing dozens of steps) + a streamlined decoder → faster inference.
