avsi Import problem

[anegroo]

Hi everybody!
I try to denoise a HDV video. In the same script I try to compare different methods stacking vertically four results in the same window. One filtering script is too complex, so I tried to import it as tx.avsi. After I stacked between others this is the only one which is working, the other three only show the first frame in the whole video. Could be the problem that I used in the script tx the same Limitedsharpen and SeeSaw script also which is used in rect2 and rect4 lines? The script:

SetMemoryMax(512)
x=Import("W:\Video\tx.avsi").Trim(3868,4868)# a complex script Cropped to the same size like "rect" below

MPEG2Source("V:\Capture-\video0002.d2v", idct=5, cpu=4)
Trim(3868,3967)

rect=Crop(0, 200,0, -610)


rect1=x.Subtitle(" 1 - Complex Script")
rect2=rect.Subtitle(" 2 - Limitedsharpen").LimitedSharpenFaster()
rect3=rect.Subtitle(" 3 - fft3dfilter").fft3dfilter()
rect4=rect.Subtitle(" 4 - SeeSaw").SeeSaw()

StackVertical(StackVertical(rect1,rect2),StackVertical(rect3,rect4))

Or there is a simpler method to include scripts in another script?
