Distorted avisynth preview

Input resolution                                              720-480
After crop                                                     690-464
After convert to square pix target resolution       690-522
If set target resolution                                     720-546 avisynth preview is normally

You are using the Avisynth FilterView not the normal Avisynth Preview.
-> Does the normal Avisynth Preview work?

Looking at the script used for the preview:

LoadPlugin("C:\PROGRA~1\Hybrid\32bit\AVISYN~1\LoadDll.dll")
LoadPlugin("C:\PROGRA~1\Hybrid\32bit\AVISYN~1\DGDecode.dll")
LoadPlugin("C:\PROGRA~1\Hybrid\32bit\AVISYN~1\TIVTC.dll")
LoadPlugin("C:\PROGRA~1\Hybrid\32bit\AVISYN~1\unblock.dll")
LoadDLL("C:\PROGRA~1\Hybrid\32bit\AVISYN~1\libfftw3f-3.dll")
SetFilterMTMode("DEFAULT_MT_MODE", MT_MULTI_INSTANCE)
# loading source: H:\!_Video\Video_Mus\4 Non Blondes\1993 - What`s Up.vob
#  input color sampling YV12
#  input luminance scale tv
Source = MPEG2Source(d2v="E:\Temp\vob_e403183f84cb79aba8cda632a1294af7_6334.d2v",info=3)
# current resolution: 720x480
SourceFiltered = Source
# deinterlacing
Source = Source.TFM(mChroma=true)
Source = Source.TDecimate(cycleR=1,cycle=5)
SourceFiltered = SourceFiltered.TFM(mChroma=true)
SourceFiltered = SourceFiltered.TDecimate(cycleR=1,cycle=5)
# cropping to 690x464
SourceFiltered = SourceFiltered.Crop(14,8,-16,-8).PointResize(692,464) # point resize part is only used for preview; workaround for a bug in avsViewer
# current resolution: 692x464  (SourceFiltered)
Source = Source.Crop(14,8,-16,-8).PointResize(692,464) # point resize part is only used for preview; workaround for a bug in avsViewer
# current resolution: 692x464  (Source)
# filtering
# scaling
Source = Source.BicubicResize(720,546)
# current resolution: 720x546
# using lanczos resize instead of nnedi3 since width after cropping isn't mod4
SourceFiltered = SourceFiltered.LanczosResize(720,546)
# stacking horizontal for filter preview
SourceFiltered = SourceFiltered.ConvertToRGB32(matrix="Rec601")
Source = Source.ConvertToRGB32(matrix="Rec601")
StackHorizontal(Source, SourceFiltered)

No clue why this is happening.
-> would need a small sample of the source to reproduce.

Sample

Does the normal Avisynth Preview work?

If set target resolution of this file 720-546 avisynth preview is normally.
This defect occurs on any file if set "Convert output to square pixel" and if "target resolution less than 700 pix"

Can't reproduce it the way you describe it. I use tons of videos with a resolution below 700.
I guess, the problem is related to the source not being progressive and at the same time not modulo 4.

When I load the source you send me a link to , crop it with 14/8/16/8, I get:

LoadPlugin("I:\Hybrid\32bit\AVISYN~1\LoadDll.dll")
LoadPlugin("I:\Hybrid\32bit\AVISYN~1\DGDecode.dll")
LoadPlugin("I:\Hybrid\32bit\AVISYN~1\TIVTC.dll")
LoadPlugin("I:\Hybrid\32bit\AVISYN~1\unblock.dll")
LoadDLL("I:\Hybrid\32bit\AVISYN~1\libfftw3f-3.dll")
SetFilterMTMode("DEFAULT_MT_MODE", MT_MULTI_INSTANCE)
# loading source: C:\Users\Selur\Desktop\1993 - What`s Up.vob

Avisynth FilterPreview works fine here, but that might be related to me using Avisynth+ 32bit instead of the normal Avisynth MT atm. for testing.
-> will send you a link for such a dev version for testing to see whether this problem is indirectly fixed by using Avisynth+.

Defect is still again with another source

[Selur]

Need a way to reproduce this otherwise I can't look into fixing this.

Ah you resized with mod4.
Now I can reproduce the issue.

[Selur]

it's a bug in avsViewer (script itself is fine), will look into it, but probably not this week, since I lack the time to look into it.
