What were you using for the interpolating and encoding? I have a powerful server with a bunch of video files and would love to try that out.
I originally started with SVP, which was decent. SVP now has a real time plug-in that can be used with various media players. It offers OK quality with the benefit of real time playback on most systems.
I experimented with other interpolators and encorders and at the end I was using Hybrid (
Welcome to the home of Hybrid | Hybrid (selur.de) ). You'll definitely want to look up guides, etc. as there are a LOT of things you can tweak (and you need to tweak for best quality) depending on the type of video you are encoding. Hybrid is pretty advanced and is basically like a wrapper around a large variety of interpolators and video and audio encoders.
You can get excellent quality with Hybrid, but you'll need to do a lot of tweaking in order to find the best settings. Generic settings from guides can provide decent to good quality depending on the video you are interpolating.
There are simpler interpolator and encoder packages, some of which include AI trained interpolators, many of which are more optimized for Anime, but some are also good with real life video. Many of these also integrate AI trained video upscalers. I haven't really messed around with these so I don't have any particular recommendations here. You can start to go down the rabbit hole by looking up Waifu2X (AI upscaler, but links to that will include branches to AI interpolators as well) which many of them are based on. Keep in mind Waifu2X isn't the best, it's just the only one coming to mind right now and can be a jumping off point to start looking up AI trained upscalers/interpolaters.
Just be aware that upscaler/interpolaters that use AI trained algorithms will take a LONG time depending on quality, length of video and whether you are upscaling or not.
