[HELP] Fehler: .stats was not created!

Okay, I'm trying to make heads and tails of what you wrote.

This error only occurs when I want to convert 60fps (from Video Editor - non-smoothly) video to 60fps video (smoothly) with AviSynth

In case the input and output frame rate are the same and you didn't remove frames in-between Interframe will not be used. (Since there is nothing to do for it.)
But since your input isn't 60fps but 59,94 fps it should work.

So what I did was:

1. Start Hybrid
   
2. Load the '60fps(non-smoothly)720p-uncompressed.avi' file
   
3. Switched F"iltering->Support" to 'Avisynth'
   
4. Enabled "Filtering->Avisynth->Frame->FPS adjust" and set it to 'Interframe'
   
5. Set "Filtering->Avisynth->Frame->FPS adjust->Interframe->Tuning" to 'Smooth'
   
6. Set "Filtering->Avisynth->Frame->FPS adjust->Interframe->Target frame rate" to '60,000'
   
7. Set "Filtering->Avisynth->Frame->FPS adjust->Interframe->Override algo." to 'Smooth'
   
8. Pressed "Filtering->Avisynth->Show current Avisynth script" which gave me:
   
   LoadCPlugin("I:\Hybrid\32bit\AVISYN~1\ffms2.dll")
LoadPlugin("I:\Hybrid\32bit\AVISYN~1\svpflow1.dll")
LoadPlugin("I:\Hybrid\32bit\AVISYN~1\svpflow2.dll")
Import("I:\Hybrid\32bit\avisynthPlugins\InterFrame2.avsi")
SetFilterMTMode("DEFAULT_MT_MODE", MT_MULTI_INSTANCE)
# loading source: C:\Users\Selur\Desktop\60fps(non-smoothly)720p-uncompressed.avi
#  input color sampling RGB32
#  input luminance scale pc
FFVideoSource("C:\Users\Selur\Desktop\60FPS(~1.AVI",cachefile="E:\Temp\avi_e18a6ebff35999ff1d096dd9f1261c1c_853323747_1_0.ffindex",fpsnum=60000,fpsden=1001,colorspace="RGB32")
# current resolution: 1280x720
ConvertToYV12(interlaced=false, matrix="PC.709")
InterFrame(NewNum=60,NewDen=1,OverrideAlgo=23,Cores=32)
# filtering
PreFetch(8)
return last
9. Pressed "Filtering->Avisynth Preview" (Preview worked fine)
   
10. Configured x264 (used a higher bitrate and changed the Level to 5.1)
    
11. Set an output name/file
    
12. Created a job
    
13. Started the job
    

-> Conversion worked fine, but didn't really change any frame since the difference between 59.94 and 60 won't affect a single frame with only 51 frames.
(Tested with SalFPS and also had no problem.)

What I've tried so far and what solves the problem is to check checkbox "Avisynth->Frame->Progressive to interlaced" along with the checkbox for convert to 60fps (" Avisynth->Frame->FPS adjust->* ").

Not looking into that since that simply makes no sense.

-> Read the sticky and provide a debug output level 9 of the job creation and job processing.
Also:
1. Does the Avisynth Preview work for you ?
2. Does using Vapoursynth with "Filtering->Vapoursynth->Other->Frame Interpolation" work for you ?

Ps.: Instead of using a RAW video I would recommend to use a lossless video format with compression.
