I used a few different AI algorithms for all of the videos, depending on a lot of factors depending on how much noise the original had, plus the later ones baked in far more detail (despite still being 1080P), which led to them upscaling better. I also used AI interpolation on each one to bring them to 48FPS from the standard 24FPS, for a way smoother presentation. I've refined it so it doesn't create as many artifacts, but there are still some lingering here and there. I'll always keep improving, though. Cheers.
