I am after some advice to a crop and resize question
source material is DVB stream of a movie that was produced in 4:3 aspect, the stream has been broadcast in 16:9 so I have the black borders on the left and right of the picture.
My goal is to remove the borders then resized it to a resolution of 720x576 with no borders.

Here is a script that does what I want, it works but is obviously not optimal, more like a backyard hack but it should demonstrate what I am attempting.

Mpeg2Source("D:\video\sample.d2v")
BicubicResize(720, 576, 0, 0.6, 0, 0, 720, 576)
Crop(88, 0,-88, 0)
BicubicResize(688, 574, 0, 0.6, 0, 0, 544, 576)
AddBorders(16, 1, 16, 1)

I am open to all suggestions as to the proper way to do this as I am sure this is not it

Hi urban tec,

Open your captured file in Vdub and insert a null transform filter. Then find the exact "Film Pixels" values by cropping all black areas.
Take that information and feed it to FitCD or MovieStacker, and let it calculate the correct parrameters

Thanks Kwag,
I couldnt figure out where to put the values into movie stacker (havent used it much) but I kept at it and while on the resize page at avisynth.org the penny dropped
For anyone that is interested this is the script now

Mpeg2Source("D:\video\sample.d2v")
Crop(94, 0, -94, 0).BicubicResize(720, 576)

Thats it

ps: I used Vdub to modify the cropping, thanks for the suggestion Kwag

By doing this you lead to a distorted picture MovieStacker (or better FitCD in this case because you can give a border value different for each side) computes the exact settings you need to don't have A/R problem.
