Since the release of v2.5.0, a significant amount of time has passed. During this period, I completely rewrote Anime4KCPP and now present the brand new v3.0.0 version.
Anime4KCPP V3 is an entirely new release and is not backward compatible with previous versions. This version no longer supports the Anime4K09 algorithm, focusing solely on optimizing the CNN-based algorithm instead. It supports CPU instruction set acceleration, OpenCL acceleration, and CUDA acceleration.
Anime4KCPP V3 utilizes FFmpeg for video processing and allows you to specify output bitrate, encoder, and pixel format to customize encoding quality to some extent. For advanced usage, VapourSynth or AviSynth is recommended.
DirectShow filters, AviSynth plugins, and VapourSynth plugins are now supported and provided as pre-compiled 32bit binaries. However, due to NVIDIA CUDA restrictions, the 32bit pre-compiled versions will not include CUDA support.
