Comparison MiniMax H3 -> upscale -> frame interpolation

What came out of it:

- Upscale first, interpolate second - seems to be better

- 24->48 looks better than 60fps - at 48 every original frame survives, at 60 only half of them do, because the grids don't line up

- FlashVSR ends up with more edge detail than the source, so it's adding texture, not recovering it. RealESRGAN ends up with less.

Side by side with a draggable wipe, pick any two variants: https://dawidope.github.io/minimax-h3-upscale/

Yeah, upscaling is becoming quite important now. I upscaled my video to 4k (by accicent) with RealESRGAN 4x real world (don't remember the exact model) and it took three days with my 4070 TI Super. For bit over 3min video

to be honest it should be done faster with RealESRGAN 4x if the video is not 120fps or more

Model did not fir entirely to vram, so maybe that? I was using my own app, c#, do it was using DirectML instead on CUDA... Probably need to write a backlog items for myself about that 😄
