How FlashVideo Turns Low‑Res Clips into 4K Video with Minimal Compute

FlashVideo introduces a two‑stage framework that first generates low‑resolution videos with strong prompt fidelity and then uses flow‑matching ODE trajectories to upscale to 4K quality in just four function evaluations, achieving top VBench‑Long scores while cutting generation time by up to five‑fold.

FlashVideo Sets New SOTA for Faster, High‑Fidelity High‑Resolution Video Generation

FlashVideo introduces a two‑stage diffusion framework that first ensures prompt fidelity at low resolution with a 5‑billion‑parameter DiT, then efficiently adds fine details at high resolution using flow matching, achieving state‑of‑the‑art quality with dramatically lower compute cost.

Adaptive Blend Pyramid Network for Real-Time Local Retouching of Ultra High-Resolution Images

The paper introduces ABPN, an Adaptive Blend Pyramid Network that achieves precise, high‑quality skin retouching and garment wrinkle removal on 4K‑8K photos in real time by combining a context‑aware local retouching layer with a novel adaptive blend pyramid layer, addressing challenges of artifact‑free detail preservation and efficient high‑resolution processing.
