Cropping didn't work, picture out of sync.

[f@chance]

The AVI file format is 640x256 25Fps. Calculating the AVISynth script for 16x9 Widescreen in PAL format turns out to be

BicubicResize(480,420,0,0.75)
AddBorders(0,78,0,78)

I want to however want o use the following script:

BicubicResize(480,448,0,0.75)
AddBorders(0,64,0,64)

This will make everything thinner and taller. What are the parameters for the Crop() function and where should it appear in the AVISynth script?

I tried:
BicubicResize(480,448,0,0.75)
AddBorders(0,64,0,64)
Crop(20, 0, 520, 576)

Didn't work and putting the Crop lime before the BicubicResize gave an error of reading location xxxxxx.

Thanks for any help.
