View Full Version : Editing vob's

Hi!
Well, I have the following problem.
I got a DVD that has just one movie which contains several episodes.
I want to reauthor it removing some episodes. But I think I have to edit the video inside vob's.
Well, what can I do? Demux video and audio and edit m2v files with some tool? And, in this case, what about the audio? Is there a way to edit vob's directly?
Ah, I just want to edit, not to reencode!

Thanks!

Does each episode have its own PGC? If so you can use IFO mode in a ripping program to create a vob for each ep (demuxing by vob-id in vobedit may also do this, not sure as I haven't tried). Then you can demux each ep into audio/video streams (e.g. using vobedit) and reauthor.

If each episode does not have its own PGC then it should at least have its own chapters, so you can rip certain chapters (or use vobedit to demux by cell ID) then demux/reauthor.

However, I'm assuming you don't want to keep the menu vobs.

Are you talking about a Multi PGC TitleSet? Each PGC is an episode and you want to replace certain episode PGCs with 15 ms blank VOBs?

Something like this?

Before

PGC_1 00:22:59.05 Video
PGC_2 00:22:59.05 Video
PGC_3 00:22:59.05 Video
PGC_4 00:22:59.05 Video
PGC_5 00:22:59.05 Video
PGC_6 00:22:59.05 Video
________________________
After

PGC_1 00:22:59.05 Video
PGC_2 00:00:00.15 Blank
PGC_3 00:22:59.05 Video
PGC_4 00:22:59.05 Video
PGC_5 00:00:00.15 Blank
PGC_6 00:22:59.05 Video

I'm currently working on a guide on accomplishing this using IFOedit and VOBedit. The method works but it's the writing that slows me down. Using freewares and no reencoding. ;)

No, it's not the case. I got just one PGC. The DVD layout you described is the one I want to get for my authoring project.
I'm working with DVDMaestro. If I define a project with several movies, would I get that DVD layout? I mean, one PGC for each movie.

I didn't know. I'm not sure how to do it but I try to get a way.
If not, I will ask you for some help! ^_^
Yesterday I was testing the last version of TMPGEnc DVD Author and it has some functionality similar to what you described. But I didn't find it as flexible as I need.


However, I'm assuming you don't want to keep the menu vobs.

You're right. I really don't want to keep it! ^_^

Thanks!

I didn't know that could be possible. Interesting...
But it's not the case. Each episode has its own opening and ending but I want to cut it off and just leave one opening and ending in the DVD for every episode. I think a playlist could help me to get each episode played as it has its own opening and ending.

Thanks!

You can have multiple PGCs in one VTS, it seems unusual that a DVD with tv eps would not have multiple PGCs. Open in DVD decryptor and use IFO mode to check.

With Maestro, it would be one title/VTS for each movie, i.e. VTS_01_1.VOB would contain ep 1, VTS_02_1.VOB would contain ep 2, etc. IMO that is better than having all the eps in one VTS with multiple PGCs.

When I've done this I've set the first play to movie1 and the end action for movie1 to start movie2.

I didn't know. I'm not sure how to do it but I try to get a way.

In DVD Decryptor etc you can select the chapters you want to rip. Or if you open the first vob in vobedit and select demux->demux by cell ID it will save all the cell IDs. That should result in a vob file for each chapter (although there could be variations, e.g. in The Two Towers the chapter that contains the layer break contains 2 cell IDs compared to 1 for the rest of them).

Each episode has its own opening and ending but I want to cut it off and just leave one opening and ending in the DVD for every episode. I think a playlist could help me to get each episode played as it has its own opening and ending.

For cutting out the opening and ending you could use Chopper XP [or vstrip (with GUI) if you need supreme accuracy]. However, it complicates matters a little, because if you wanted to use the title button on your remote to switch to episode 4, you wouldn't get the intro/outro. AFAIK you must use a menu under these circumstances (and a good idea would be to disable the title and maybe the next/previous buttons in the user prohibition options of DVDMaestro).

One other thing, be aware of sync issues, when cutting vobs some sort of audio delay is often introduced.
