What AI says about FastBlend

FastBlend is a model-free video-smoothing algorithm designed to render fluent, flicker-free videos by blending frames and keyframes. It is distributed as a Stable Diffusion WebUI extension or as an independent Python-based web UI, with dependencies such as Gradio, numpy, imageio, OpenCV, and CUDA-enabled CuPy. The API exposes functions like smooth_video and interpolate_video to combine a guide video with an optional style video for cohesive, polished video outputs.
