The free version made impressive work of the DVD version of "Beyond the Minds Eye" a particularly tricky title to upscale with 1992 CGI Animation. So I purchased the full version.
I definitely recommend anyone also looking to upscale some video - START HERE.
To the developer:
Please add the ability to turn off image resizing before upscaling, some encoding presets, and continue to tune performance.
Right now I can't quite recommend this over Waifu2x-extension-gui for more advanced users. If you need to use custom models, encoder settings, NVENC support, etc, go with that instead.
