That would be great !

As I understand, your script only works with video events and changes the pixel aspect ratio of all the video files in the media pool.
What I would need is the same script but to convert still images (my images are .psd file) I need to convert them from 1.000 to 0.9091. Also if possible, i'd need this script to affect files only in a specified media pool directory. If not possible it could affect only .psd file or only still images on a specified track.
Thanks for your help !

Nat, There is no way to affect just one media bin that I can see from the Script API. I also don’t think there’s even a way to just affect the selected files because clips in the media bins don’t have a selected attribute. So I modified my script to process media based on file extension and set it up to process .psd files for you. I’ll probably modify it to add a dialog box which prompts for the file extension but this should get you up and running for now:

/**

 * Program: ChangeMediaPoolAspectRatioPSD.js

 * Description: This script will change the aspect ration of all the video media in

 *              the project's media pool that end with the extension .psd

 *              to match that of the project.
