Avisynth: When to resize? filter order?
 

Hi,

Given the following script used to encode a fairly noisy VHS Interlaced source to DVD:

#########################################
LoadPlugin("D:\Video\Avisynth\Plugins\LoadPluginEx .dll")
LoadPlugin("D:\Video\Avisynth\Plugins\Convolution3 D.dll")

AVISource("d:\Video\Capture\Clip10001.avi")

KillAudio()

Seg1= Trim(32,5129).FadeIn2(30).FadeOut2(30)
Seg2= Trim(5147,19821).FadeIn2(30).FadeOut2(30)
Seg3= Trim(19830,36708).FadeIn2(30).FadeOut2(30)
Seg4= Trim(36721,38842).FadeIn2(30).FadeOut2(60)

JoinClips= Seg1++Seg2++Seg3++Seg4

PreFilter= JoinClips.Crop(16,8,-16,-8).BilinearResize(352,464).SeparateFields()

FilteredEven= PreFilter.SelectEven().Undot().Unfilter(20,20).Cnr 2().FluxSmooth().Convolution3D(0,32,128,16,32,10,0 )

FilteredOdd= PreFilter.SelectOdd().Undot().Unfilter(20,20).Cnr2 ().FluxSmooth().Convolution3D(0,32,128,16,32,10,0)

PostFilter= Interleave(FilteredEven,FilteredOdd).Weave().AddBo rders(0,8,0,8)

return PostFilter

Can anyone offer any reasons why I should or shouldn't resize after applying filters? Also, should Unfilter be the last filter, or is it where it should be?

Thanks!
