  We present NNVISR - an open-source filter plugin for the VapourSynth video
processing framework, which facilitates the application of neural networks for
various kinds of video enhancing tasks, including denoising, super resolution,
interpolation, and spatio-temporal super-resolution. NNVISR fills the gap
between video enhancement neural networks and video processing pipelines, by
accepting any network that enhances a group of frames, and handling all other
network agnostic details during video processing. NNVISR is publicly released
at https://github.com/tongyuantongyu/vs-NNVISR.
