[FFmpeg-user] Trying to convert DVD based movie into images

Hello ffmpeg-experts,

I am now trying to convert DVD based movie into images.  The movie resolution is 720px x 480px.
But I know DVD's pixel is not square.  So I thought the following command:

$ ffmpeg -i original.avi -an -q:v 1 -vf "trim=1200:1500,setpts=PTS-STARTPTS,scale=853x480:flags=bicubic" imgs/img%06d.png

But I'm aware that it is a bit upscaling.  Is there any good approach to do?
