[HELP] Weird tear or noise issue while using Vapoursynth

[noy]

Hi there,

This is what I'm using:

• Windows 10
  
• Hybrid rev 2021.07.18.1
  
• Vapoursynth(Interframe/SVP 60fps)
  
• Source video fps(30.93 fps)
  

I've tested 3 different filter "No XSynth", "Avisynth" and "Vapoursynth" to double the framerate, only "Vapoursynth' does the best performance to my video(it has smooth motion like 60fps), "No XSynth" and "Avisynth" looks like still 30fps even the framerate has set to 60fps.

There is no bug happened while outputing the video. Just a question to the performance while the video has a speedy motion scene, there has some tear or noise after filtering:



"No XSynth" and "Avisynth" almost has no issue like this(actually a little, but it would not worse like this).

Here are 2 images for the configuration I used, the other settings are still default:

_______1st image_______

Only 3 changes here

1. Enable Frame Interpolation and use Interframe/SVP
   
2. Set FPS to 60
   
3. Set Tuning to Smooth
   

_______2nd image_______

Only 2 changes

1. Change the Bitrate from 1500 to 10500
   
2. AVC Profile/Level set from 4.1 to 5.1
   

Is there a way to avoid this issue?
