45Gb into DVD-R

[jkapa]

I´m currently authoring a DVD on Ulead WorkSshop (3+ hours of video) and came up with a problem.

I´ve made a simple menu wiht background pictures and 4 sub-menus. All the clips used are MPEG-2 made in TMPGEnc (not all of them are the same resolution - i don´t know if that´s a problem). The total movie data is 3.65Gb.

In the end I choose to create a directory with the VIDEO_TS to later burn with Nero. "Do not convert compliant files" is checked but still the estimate file size is 45Gb and the process takes more than 4 hours.

If all the the files are MPEG-2 why does it reconvert? - at least I think it does judging by the time and final data size. Something is wrong but I can´t put my finger on it. Can someone give a hand with this?

Different bit rates should not be a problem as long as all the files are DVD compliant. Perhaps you don't have compliant files and it IS transcoding the ones you have.
That being said though . . .depending on the complexity of your menus and speed of your computer, ESPECIALLY if you have lots of motion menus, 4 hours is not an unreasonable time to create a project. I have had some take double that much time.
The bit about 45GB file size is interesting though. Are you sure it's not 4.5GB? Have you actually created the project to see how big the final file is and how long it takes. Workshop's completion estimator is often not real accurate when working.
What are your creation settings in Workshop? Even though you think you have compliant files, if you don't, it is transcoding them to whatever settings you established.
Good luck.
PS - 3 plus hours is a hell of a lot of video to try and stick on a DVD, your bit rates must be pretty darn low. How is the quality if I might ask?

Thanks for your reply.

Don´t know much about the bit rates, it´s kind of an unambitious project - I just want to be able to see stuff I dl on the net on my living room DVD.

The menu is very simple - it does NOT have any motion - and my PC is a 2.8 GHz/512Mb DDR not exactly a slow computer.

It is definitely reencoding because I´ve done a test with a single clip and although you´re right about the estimate size and the real output being VERY different the file grew from 250 Mb to 400.

All the files are encoded in TMPGEnc and are MPEG-2 - is there any other requirement to make a file compatible?


This is what happens when I select make disc:








And after this there´s a new menu:

The screen shots are nice.
Just because it says it is needing 45GB of HD space to create your file does not mean that the final file will be that large. It is calculating the space needed for your orignial files, the transcoded files, then the final project files. Still though, 10x the original size seems a bit large. 3x is normal.
I don't know from what you have shown, but my guess is that there is a problem with your original MPEG2s. I don't use TempGnc to encode with so I am not familiar with the settings needed to make a DVD compliant file, but I am guessing you have something wrong. A file can be a good MPEG2 but not be DVD compatible.
Try reading up on TempGnc and finding out the proper settings for DVD video compliant files.
Good luck.

spmc thanks for your help.

I got it to work but i had ro reencode all the files to meet necessary spec (a question of resolution and audio Hz) - DVD WS is a a bit dumb or maybe just makes sure that a DVD authored by it is compatible with most DVD players.

Anyway it´s cool now. Bye
