How do I crop this 4:3 ntsc movie?

[Jeremy Duncan]

It's the Terminator 3, ntsc, 4:3

This is how I do it now.
I got this crop and resize from googling.

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\DGDecode.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\nicaudio.dll")

video=mpeg2Source("C:\Documents and Settings\Home\Desktop\encode project.d2v")
audio=NicAC3Source("C:\Documents and Settings\Home\Desktop\encode project T80 3_2ch 448Kbps DELAY 0ms.ac3")
AudioDub(video,audio)

Crop(8,0,-8,-0)
LanczosResize(640,480)

converttoyv12()

Here is the vob sample taken from dgsplit. It was ripped using dvdfabfree.

My reason for posting this thread is if I'm not doing it right then I hope somebody will post the correct crop and resize to use. :)

You don't need converttoyv12()
Do you really need audio in this script? You can encode it separately or mux as is.
Don't know about specifications etc., but personally I never use crop when there is no black borders. I think aspect ratio will be correct without cropping but you can try to find round objects in some scenes and check.
Also, resolution 640x480 is too low for my taste. You can leave it as is or make something like 704x528, if you want.

UPD:
by the way imo you have a bit crapy DVD because I believe T3 should be at least 16x9

I see no reason to crop anything. Just encode as is (720x480) and set the DAR flag in the stream at muxing.

Well I tried with no resizing or cropping or audio.
Then in ts muxer I changed the aspect ratio to square, and I tried without changing the aspect ratio in ts muxer.
Neither ts was the same AR as from the dvd.

So i tried with my script from the first post with no audio and the ts was the same AR as from the dvd disk.
The reason the picture is so big is it was resized.

I will post the two pictures:
