help with inserting vob id

[Ganglion5]

Does anyone know how to (or know of a guide) place or insert vob ID's or PGC ID's while you're authoring? The reason I ask this is a lot of movies have VOB ID's inserted in the middle of the main movie file. But once you author it with maestro, for example, you lose all those VOB id's and cell id's. I'm wondering if there's anyway of keeping those ID points, (even if it means inserting it manually). I've been working mostly with maestro, but I don't think maestro has this capability. Does anyone know if scenarist has this function? Thank you for your input.

I read a post a little while ago that provided the neccessary steps to manually change the vob and cell ids. Mpucoder page is describing all this information.

However I know that vob and cell ids is a convinient way for an authoring program to manipulate its assets. A standalone doesn't really care about ids. All it cares about is for the asset to reside in the address given by the ifo. U can mess as hard as u can with the ids in Maestro as long as u put the relevant audio and video in its right spot.

To return to your question. A movie in Maestro is a vob set and has a vob id. The 1st movie has id 1 and so on. Any playlist defined in a movie is a pgc numbered the same way. The 1st playlist is 1 etc. The same principal goes for the cell ids. Each chapter is a cell and chapter 1 is id 1.

How many times are you going to Post and ask the same question? I answered your question already in another thread. If you still dont understand how to do it then ask for more info, please do not cross-post... its a forum no no..

Thanks. That's very good to know.
I haven't tried this yet, so I'll give it a run.
You said in Maestro, the movie one has 1 set of VOB's and ID 1. However, is there anyway to have multiple ID's in the same set of VOB. I know that's what happens in a lot of the movies nowadays. They stick a trailer or something into the same VOB as the main movie. And of course Maestro doesn't know that after you encode it, and it just gives the trailer the same ID as the main movie (which is what I'm trying to figure out if Maestro can change that).
BTW, what's this MPucoder site that you mentioned?
Thanks again.

MPUcoders website is but a google search away. Anyway, before you dive into changing VOB/CELL ID's, you really need to understand DVD structure, packets, headers and bytes. HEX editing knowledge is a must.

Yes, every VOB have a VOB ID and a CELL ID, they can both be 1 as Maestro can yield, or even a IFOedit mux. Usually, not always, chapters are designated with different CELL ID's. Multiple movies/segments within a VOB can have any combination of VOB ID/CELL ID (Within the DVD Spec). SO, if you want to edit them / change them / hack them, YES you most certainly can. You could demux the project, load into scenarist and set your VOB ID's as you wish. You are specifically asking about Maestro and the VOB ID of 1 output issue. SO, to manually edit this (again) you currently have 4 choices.

1. Use VOBedit and manually change every VOB ID byte in the packet stream (have fun - only a few thousand to change).
2. Use VOBedit's JOINCLIPS mode to set the VOB ID to another number.
3. Use a Hex editor script to alter the bytes automatically.
4. Write your own VOB parser that does this for you.

Have fun.

Sorry about the mult posts. I was desperate and I didn't get any replies on the forum until you answered. So I posted this in between. Anyway, thanks for your response.
So you're saying I can use scenarist to create my own vob id's that maestro can't do? I guess I have to find a good guide in using scenarist and start from scratch.
I'll give VOB edit another try, but I didn't have success using it to remux a project before, and had been afraid of it since.
Hex Editor seems really complicated. I'll try to find a good guide on the net.
Again, thanks.
