This is a computer with 9700+16G+2060. In my mind, 2060 is OK for this app. I download a video in 12000kbps 91 seconds, the whole file is 151MB. I Interpolate 4X and down to 60 fps. Split frames into sections and section size is 250. Now I'm rendering and it renders 18 frames per hour!!! The whole video has 2208 frames and yes, maybe I 'll render this file 5 days! I don't know what problem it has, but it's too slow for me. What about you? I really really want to konw.

Have you got any solution to this problem?

Mine has an i7-6700+8gb+10502gb.
I only render 10 frames per hour for 2x interpolation mode.
My video is about 6000 frames and if you calculate that, you would need 25 clean days for that.
I have seen this video, 

I am aware he's only having 15fps video, but he rendered it in 4k resolution!
Anyone with the solution please come forward and teach us the solution.
I am very excited and want to support this developer until it is fully published but I do need to see real results first.
I am not being bossy or being investor-like, I just want to make sure this is not a scam or something like the rubber band phone.
