Reposting my comment about upscaling from
O-Dio's thread, some people might be interested.
If anyone wants to do similar upscaling of videos as the ones we've seen for

as well for better interpolations if you don't want to waste your time with rendering. (You might need a good Graphic Card but it's significantly faster.) Frame interpolation with Topaz is alright, there isn't any notable difference between this AI and the one used by Flowframe, except for the fact that if you want to upscale a video to 4k within Topaz and maybe get 120fps you just can't. Frame interpolation with Flowframes is technically better, but it probably doesn't matter that much for MMDs videos.
On Topaz I recommend you to use presets before changing anything. You can use 4k60fps, but I've seen less artifacts for some animations if you just upscale a video to 4k with the original frame rate. So just upscale your video to 4k and do not change the frame rate.
As for the filters :
- Don't use Stabilization
- Nor Motion Deblur
And unselect "Frame Interpolation" too.
The thing here is to do an interpolation with Flowframes later on to get the best quality possible, OR a second rendering within Topaz but this time with your 4k video output just for interpolation. (If that's what you want to do, select the "Apollo" AI model. Chronos Fast makes it worse for MMD.)
Next, select "Enhancement" type "Progressive" with the Proteus AI model, relative to auto with 100% sharpening. If movement are really fast, just use auto. Don't touch anything else. Makes sure it's in H264 and you can render your video. Flowframes is pretty straightforward, select the recommended options and choose 60, 120, 240 or more frame per seconds. I find it better with just 60 fps. (There's a bunch of other AI model like Gaia which is supposed to be better for computer generated video, but on all my tests, Proteus seems to be the better one in every way.)

to some upscale i've made from
god tier / old school MMD creators like Furui, YunaTBM, @nubioda and @mmdmonmon. It goes from 720p to 4k60fps, file size is pretty decent thanks to the encoding process of Flowframes.
