Key Technical Highlights
Single-Step Diffusion: Distills multi-step diffusion into a single inference step, significantly improving speed
Local Sparse Attention: Efficiently handles high-resolution inputs while avoiding texture repetition and positional drift
Lightweight Conditional Decoder: Reconstructs detail by conditioning on the original low-res frame, improving temporal stability and reducing flicker
Native Streaming Video Support: Designed for video-first input, balancing speed and output fidelity at 2K / 4K resolution
Who It’s For
Content creators working with generative outputs (e.g. Runway, Sora)
Developers of video enhancement tools
Restoration workflows: archival footage, film cleanup, AI reprocessing pipelines
Video AI is moving fast, but resolution shouldn’t lag behind. FlashVSR currently offers one of the best trade-offs between speed and quality among diffusion-based video upscaling models.
