Thanks for your quick replies!
You're right, it was a mistake!
In fact it takes 20 hours to encode with the script and the encoding without using the script is done in less than 7-8 hours!
You see there is a huge difference in time! I wanna know is it worth it?
The CQ 80 and below it is perfect because the formula prediction says if I use that CQ the final file size is not bigger than 2.4 GB that is the size I need.
I extracted some frames from the 2 m2v and I see the picture with the script is blurred and not as sharp as the one without the script but it's not so important. When the filters are not applied the picture is more like the original DVD.
If I drop STMedianFilter and Temporal Smoother, the encoding time becomes much less! I am not very familiar with these filters, how do these two filters effect on the picture quality? does the script make the final file size smaller?
The main movie is 5.5GB and there is 1.83 GB Deleted Scenes, Extra Features and Menus.
I want to keep all of them on the DVD-R so I think the main movie compression should be over 50%.
I think there is nothing except IfoEdit that can keep the original DVD structure and it doesn't recode itself.
IfoEdit creates and stores all I-frames of the standard GOP structure in a text file, I meant should I use that TMPG I-frames template when encoding KDVD m2v that is to be remuxed by IfoEdit later.
again thanks for your replies.
