I need some help with interpolation videos, lots of detail in post

I have been trying to get some interpolation right for a few weeks now, and I need some help with it. I have tried a lot of things, all of which I will go into detail about in this post.

I started trying to interpolate videos as I read that a lot of TVs did this and wondered if there was a way I can do it on my computer. I went on youtube and searched for interpolation and found loads of videos of varying quality. After a while I started to look more specifically at interpolations of animation, as I am a fan of animated movies. I found numerous examples of interpolations of animation, this probably being the best I found: https://www.youtube.com/watch?v=sPAP...A&index=4&t=0s

I also focused on this one as in the comments of the video the person who uploaded it said it was done with SVP, so that gave me a hint as to where to start.

I tried this tutorial: http://www.spirton.com/convert-videos-to-60fps/
and wasn't impressed by the results. The camera looked smooth, but motion on screen still looked like it was running at 30fps.

I then made a post about this: https://forum.videohelp.com/threads/...e3#post2524201

and I got a lot of useful advice, which allowed me to produce a much better interpolation, the best example of which is probably this: https://1drv.ms/u/s!AiOx2LWATSlvzjpQLo1axA8V3dqT

However, it still didn't look as good as the youtube video. There are also quite a few duplicate frames in that video.

The script I was using to make that video was something like this:

Code:
PluginPath = "C:\Users\bradw\Downloads\MeGUI-2836-32\tools\lsmash\"
LoadPlugin(PluginPath+"LSMASHSource.dll")
LoadPlugin("C:\Users\bradw\Downloads\MeGUI-2836-32\tools\avisynth_plugin\svpflow1.dll")
LoadPlugin("C:\Users\bradw\Downloads\MeGUI-2836-32\tools\avisynth_plugin\svpflow2.dll")
LSMASHVideoSource("C:\Users\bradw\Documents\file.mkv") 
AssumeFPS(24000,1001)
super=SVSuper("{gpu:0}")
vectors=SVAnalyse(super, "{block:{w:16}}") # 16 is the default, you can try 8, 24, and 32 also
SVSmoothFps(super, vectors, "{rate:{num:5, den:2, algo:2, scene:{mode:1}}}", url="www.svp-team.com", mt=1)
My original source for these tests is here: https://1drv.ms/v/s!AiOx2LWATSlvzjxoZFpKvN_R2yu_

I am not very knowledgeable on the subject of interpolation, nor am I of avisynth or video encoding in general, however I do have a basic understanding of these scripts.


Any advice on what I can do in order to make my interpolations look smoother would be greatly appreciated, I hope I have provided enough information and enough samples in this post, but if you need more, I will be happy to find them.

Also, I use MeGUI to run these avisynth scripts.

My computer specs (incase it matters):

AMD 10-7300
8GB RAM
1TB HDD
Radeon R6 integrated graphics.
It's a Lenovo Z50-75 laptop.
