Video size is change after edit

Hi,

I'm using the module for a while, and it works great. Thanks for contributing the module.

Recently I added e-commerce and set up video node as file product. So now when creating a video node I'm specifying two video files: the one which can be played over the net (a small size quicktime clip), and a large avi movie which I'm selling. The quicktime is uploaded through Video File field, and the large "for sell" file through the EC File path product field.

I'm using ffmpeg to Enable resolution and Enable playtime.

Now, after hitting submit the file size pertain to the quicktime clip (say hundreds of kb), but after i edit the video node (click edit, do nothing, and save it) the file size is CHANGED to capture the large/high-quality file I'm intend to sell (tens of mb).

Is this "by design"? could it be amended to capture the large/high-quality file size I'm intend to sell in the first place?

Regards,
