Hi from Paris
Thanks for all your topics and advice.
I have two question.
First: Because i'm using a lot of different picture with different pixel ratio, how can i find a script to get the same pixel aspect ratio, and eventually the same field order.

and
Second: i don't understand very much aspectratio.

Thank you very much
Keaton

Here's a bit of sample code that might help:





var media : Media = Vegas.Project.MediaPool["C:\\images\\image1.bmp"];

var stream : VideoStream = media.Streams[0];

stream.PixelAspectRatio = 1.0;

stream.FieldOrder = VideoFieldOrder.Progressive;

Dear Sonic

I try but i doesn't work.

/**
* This script will change pixel aspect ratio and fieldorder all events on the selected track
*
*
*
* 29/07/2003
**/
import System.Windows.Forms;
import SonicFoundry.Vegas;
try{
var stream : VideoStream = media.Streams[0];
var mediaEnum = new Enumerator(Vegas.Project.MediaPool);
while(!mediaEnum.atEnd()){
var media = mediaEnum.item();
if(media.HasVideo()) {
stream.PixelAspectRatio = 1.0;
stream.FieldOrder = VideoFieldOrder.UpperFieldFirst;
}
}
mediaEnum.moveNext();
}
catch (e){
}

Where I Wrong?
I try to change all video in the media pool to have the same field order and aspect ratio.
thanks for your patience.

It looks like you are just missing the line of code that gets the
first video stream for the media object.

Try this:



/**

* This script will change pixel aspect ratio and fieldorder all events

* on the selected track

*

*

* 

* 29/07/2003

**/

import System.Windows.Forms;

import SonicFoundry.Vegas;



try {

    var stream : VideoStream = media.Streams[0];

    var mediaEnum = new Enumerator(Vegas.Project.MediaPool);

    while (!mediaEnum.atEnd()){

        var media = mediaEnum.item();

        if (media.HasVideo()) {

            var stream : VideoStream = media.Streams.GetItemByMediaType(MediaType.Video, 0);

            stream.PixelAspectRatio = 1.0;

            stream.FieldOrder = VideoFieldOrder.UpperFieldFirst;

        }

    }

    mediaEnum.moveNext();

}

catch (e){ 

}
