Mixing 4:3 & 16:9 using dvdauthor

[juhani]

Hi!!

I have a couple of small videofiles I would like to burn as a DVD. The files are in mpeg2 stright from DVB and have been rebuilt using mplex to vob.

A menu has been made using spumux and the whole project is now ready to be handed over to dvdauthor for construction of the DVD-filestructure.

BUT ... one of the files is in 4:3 and the others are in 16:9. If I burn them right of without specifying aspect ratio the system will give all the files the same as the first file e.i. 16:9. This mucks up the viewing later on of the DVD since it will show the 4:3 video in 16:9.

Is there anyway to tell dvdauthor what aspect ratio every part of the DVD has and still only use one menu?

Below is an example of the XML I use:

<dvdauthor> <vmgm /> <titleset> 
<menus>
<pgc entry="root">
<vob file="C:\temp\menu.vob"/><button>g0 = 1 ; jump title 1 ; </button>
<button>g0 = 2 ; jump title 2 ; </button>
<button>g0 = 100 ; jump title 1 ; </button>
</pgc></menus>
<titles>
<pgc> <vob file="C:\temp\TEST001_1.vob" chapters=" 00:00:00" /> <post> if(g0==100){jump title 2;}else{call menu;} </post> </pgc>
<pgc> <vob file="C:\temp\TEST002_1.vob" chapters=" 00:00:00" /> <post> call menu; </post> </pgc>
</titles> </titleset> </dvdauthor>

If DVDAuthor strictly follows the DVD spec, then you have to put the 4:3 material in a different titleset to the 16:9 material. A titleset can only have a single aspect ratio, so if you have multiple aspect ratios, you have to use multiple titlesets. If DVD Author cannot do this, create two titlesets, author, then use PGCEdit to fix the aspect ratios in the ifo files afterwards.

So in other words I can't do what I want to do due to the DVD standard?

What I want is one menu with a menu-item for each of the three video pieces and a fourth item to play them all in a row:

 -----------------------
 |  Menu               |
 |  1: Video 1 (16:9)  |
 |  2: Video 2 (4:3)   |
 |  3: Video 3 (16:9)  |
 |  Play all           |
 -----------------------

But if I must put the 16:9's and the 4:3 in two different titlesets then (if I understand this correctly) I have to have a menu for each titleset?

 -----------------------  -----------------------  -----------------------
 |  Menu               |  |  Menu 16:9          |  |  Menu 4:3           |
 |  1: 16:9            |  |  1: Video 1 (16:9)  |  |  1: Video 2 (4:3)   |
 |  2: 4:3             |  |  2: Video 3 (16:9)  |  |                     |
 |                     |  |                     |  |                     |
 |                     |  |  Play all           |  |  Play all           |
-----------------------  -----------------------  -----------------------

Thus Play All will only play Video 1 and 3 or Video 2.

Or is it possible to divide the videos in to several titlesets and still use only one menu and a Play All command? Is it possible to have one titleset for each Video 1, video 2 and video 3 (so they will be in the correct order to start with) and then have only one menu?

It is possible. But you will need some more scripting.
Your 'simple' menu:
-----------------------
| Menu |
| 1: Video 1 (16:9) |
| 2: Video 2 (4:3) |
| 3: Video 3 (16:9) |
| Play all |
-----------------------
needs to be set up in the VMGM domain.
In each titleset you automatically start playing the title.
You will need another dummy pgc in the VMGM domain to set up the 'Play all' functionality. The 'Play all' button sets a register (like g0=1) which is checked after the title (if(g0==1){call vmgm menu 2;}else{call vmgm menu 1;}. Another register should be set in the same command (post command for each title) to point to the next title. You can use GfD to create this kind of DVD if you activate the 'Use titlesets' functionality. It will automatically set up the script, then you can have a look, how it works.

I had to do this just a couple of days ago. I had a big 4:3 one and a small 16:9 one that I wanted to play in the middle of the 4:3 ones. These were a collection of music videos. I split the 4:3 one into two pieces and just authored them as 2 separate titles in DVDAuthorGUI. The problem is that it'll put all titles into the same VTS, and you can't mix DARs. So, I wound up with two 4:3 titles in the same VTS and then added the 16:9 one in a new VTS using PGCEdit and File->Import VTST Title. I also had to create some dummy menus so I could go back and forth between the various titles.

I agree that it would be nice to be able to do this more easily using DVDAuthorGUI, but I haven't a clue how to edit the project file. Nor do I know if I overlooked something in DVDAuthorGUI that allows this to happen.

[dinh]

can you do this by manually making an xml file for dvdauthor?

[manono]

Probably, but I don't know how and don't need to.

ok thanks anyway
