I spent the last three nights upscaling the "Gundam Wing: Endless Waltz" OVA DVDs to a proper 4k upscale using Chainner & the AI upscaler Ultramix smooth. This came out extremely well done I feel. It's extremely crisp and clean. Took around 7 hours per episode!  
I did have to initially record them from PotPlayer on Windows to use qtgmc deinterlace to remove the random interlaced frames first. But yeah it looks so good. I even converted the subtitles to set.
