Hi there, I did mention this in DMs ages ago but did want to make a proper issue post. It seems that "No Resizing" is bugged currently. As the setup in the image below shows, no resizing is selected.

But these settings result in the following generated script:

LoadPlugin("FFMS2.dll")
LoadPlugin("masktools2.dll")
LoadPlugin("mvtools2.dll")
LoadPlugin("nnedi3.dll")
LoadPlugin("RgTools.dll")
LoadPlugin("fft3dfilter.dll")
LoadPlugin("hqdn3d.dll")
Import("Zs_RF_Shared.avsi")
Import("QTGMC.avsi")
Import("TemporalDegrain.avs")
FFmpegSource2("E:\Video\Follow My Voice\K4_t05.mkv", atrack=-1)
QTGMC
nnedi3_rpow2(2)
Lanczos4Resize(640, 480)
AddBorders(40, 0, 40, 0)

It seems to resize the image to 640x480 while adding borders to the side to make it 720x480, which it was originally. Ideally there would be no resizing at all.
