Avisynth resizing/letterboxing problem

[czerro]

I'm attempting to resize a 640x480 source to 480x480 letterbox (for SVCD creation in QuENC) using Avisynth except the output looks funky. I'm new to Avisynth so I'm probably just missing something obvious. The picture is perfect, except the very bottom most row of pixels in the screen become stretched. I really don't know a better way to describe it. Here is my AVS script:

AviSource("movie.avi")
Lanczos4Resize(480,480,0,0,640,480)
LetterBox(60,60,0)

For easy avisynth scripts download fitcd. Great little app that will create your avisynth script for you. You just select your output size and save the file.

Sometimes a picture says more than a 1000 words... Post a screenshot!

A 640x480 source is likely 4:3. All you have to do is resize to 480x480 for SVCD:

AviSource("movie.avi")
Lanczos4Resize(480,480)

The SVCD player will play the video as 4:3.
