How to create VOB from MPEG with DVDAuthor?

[FredThompson]

Would someone please tell me the command call which would take a pulldown 480x480 24fps mpeg and mux it into a pulldown 480x480 VOB using DVDAuthor?

Additionally, how is the aspect ratio set?

DVDAuthor can take MPG files but it's reporting back errors about missing VOBU values.

DVDAuthor will only except mpgs with blank nav packets. Using MPLEX from mpegtools option -f8 will work. DVDAuthor will scan the video stream for the resolution. The command is [aspect="4:3|16:9"].

DVDAuthor can't take anything else but mpg.

like to see what happens when you give it 480x480 video.

DVD resolutions are 720x480 704x480 352x480.

As for the 24fps "pull down" again the info is in the stream the dvd player reads the flags set for film.

Good luck, how did you get to the questions you asked? After 1133
posts.

It handles 480x480 just fine.

Here's the original call I tried but got puked on wrt VOBU:

"C:\Program Files\TyTool 3\dvdauthor" -o "C:\Working\DTiVo" --title -c0,300,600,900,1200,1500,1800,2100,2400,2700 --instructions post=vmgm --file="E:\Birds of Prey\01 Pilot.mpg.vob"

Do you mean, "Why are you posting such an elementary question if you've got 1133 posts?" There are lots of other areas wrt video.

This just popped up tonight. I was using TyTool to make discs from SVCD source and saw it wasn't properly handling pulldown. It works fine with 25 and 30 fps, just not 24. TyTool gets confused during its VOB-Mux process and really makes a mess. The file is the proper size, the problem is pulldown is gone. DVDPatcher doesn't help, either. Darn.

dvdauthor can't multiplex, so you will need to use another tool to create the mpeg with blank NAV packets. mplex is a common tool used for this. You could also use the new muxman being discussed on this forum.
Your problem with dvdauthor not liking 24fps material has been fixed recently with 0.6.11. I would suggest that you try using the latest version.

Documentation for DVDAUthor is quite sparse. I've checked every page linked on the DVDAuthor homepage as well as used multiple search engines. The usual response is, "get on the mailing list." I've done that. Lots of chatter. Is there, anywhere, a comprehensive reference for DVDAuthor?

can you tell me which mplex and DVDAuthor 0.6.11.1 commands would be used?

[liquid217]

for mplex, the command is:
mplex.exe -f 8 -o output.mpg input.m2v input.ac3
input.m2v and input.ac3 are obviously the elementry streams needed for the outputed file.

For dvdauthor 0.6.X, the XML is the main way of controlling the layout of the dvd. By using XML (instead of the command line), it gives the user more options and control over the dvd layout. Once the XML is built, simply run.

dvdauthor.exe -x config.xml

A simple XML would be described below.

<dvdauthor dest="C:\dvd">

<titleset>
<titles>
<video format="ntsc" />
<pgc>
<vob file="outfile.mpg" chapters="0,300,600,900,1200,1500,1800,2100,2400,2700" />
</pgc>
</titles>
</titleset>
</dvdauthor>


After reading the command you were using, I believe that the above XML should do exactly as you need.

edit: I doubt that you would ever need anything this complicated, but I found a very detailed XML, that is a good reference guide to making a more complex dvd using dvdauthor. www.wershofen.de/downloads/dvdauthor.xml

Thanks. The question about docs wasn't just for me, it's to help development of TyTool.

[liquid217]

Another option you might consider is downloading one of the guis for dvdauthor, and seeing how they create the fileset. For example, DVDAuthorGUI, simply creates a batch file that calls mplex, spumux, and dvdauthor as needed to create the dvd fileset. If it would help you any, I would be more than happy to share the sourcecode to dvdauthorgui with you and the developers if needed.

Wow! That's a VERY generous offer. Thanks!
