Strange, last message in the log is that the encoding was started:

Does the Avisynth Preview work ?

Looking at the used Avisynth script:

ClearAutoloadDirs()
SetFilterMTMode("DEFAULT_MT_MODE", MT_MULTI_INSTANCE)
LoadPlugin("C:\PROGRA~1\Hybrid\32bit\avisynthPlugins\LSMASHSource.dll")
LoadPlugin("C:\PROGRA~1\Hybrid\32bit\avisynthPlugins\svpflow1.dll")
LoadPlugin("C:\PROGRA~1\Hybrid\32bit\avisynthPlugins\svpflow2.dll")
Import("C:\Program Files\Hybrid\32bit\avisynthPlugins\InterFrame2.avsi")
# loading source: C:\Users\VazhaGV\Documents\rooster.mp4
# color sampling YV12@8, matrix: bt709, scantyp: progressive, luminance scale: limited
LWLibavVideoSource("C:\Users\VazhaGV\DOCUME~1\rooster.mp4",cache=false,format="YUV420P8", prefer_hw=0,repeat=true)
# current resolution: 4096x2304
InterFrame(NewNum=60,NewDen=1,Tuning="Smooth",Cores=48)
# filtering

# setting output fps to 60.000fps

#  output: color sampling YV12@8, matrix: bt709, scantyp: progressive, luminance scale: limited
return last

a. I would recommend enabling GPU support
b. What is the RAM usage of vsViewer when using the Avisynth Preview and scrolling through the source?
