help editing DVD / VOBs files

[mariano]

Hello everyone,

I don't know either I posted this in the right place or not... sorry, I'm new in this site and in the video editing world.

Now, my problem:

I have a DVD and I need to edit (suppress) some parts of the videos without loosing the subtitles, audio or menu. I have tried different things, but I couldn't make it. For example:

I used AVS Video Converter to suppress what I wanted from each VOB file. The cut is perfect but when I tried to put it back into the DVD I loose the audio and subtitles, but the VOB file by itself have the audio.

Then I used VobBlanker wich allow me to take the whole DVD and edit video by video... but I had two problems: 1 - I can't cut the video where I want (I mean in the second that I want), so, as result I have the video one second before or just one early but no in the middle. 2- If I take the one second early cutted video (which is close waht I want) the video don't have some mileseconds audio.

I managed to get the audio from this last video and I could fix it, but now I don't know how to replace it in each VOB video.

Hope someone can help me.

C.U.

You are going to find it very difficult to edit VOB files directly. Probably impossible. You are doomed to completely destroy the chapter and sync information within the IFO/VOB indexes if you try inserting blank cells or deleting cells.

It is much easier to re-author the the main video and create a new menu with a proper editor like Sony Vegas

Hello transporterfan,

Thanks to reply!

This is the point... I can't lose the menu or subtitles.

I will keep trying.

You can't easily do what you want. If you want to do frame accurate edits on the video, then you have to change the timing on the subtitles, and re-author the DVD.

Someone with more experience than you have might be able to extract the video, audio, graphics and subpictures from the old menus to use as assets in their authoring program. ...or use pgcedit to re-write the instructions in the PGCs and insert the new VOBs from re-authoring back into the existing structure. Learning enough to do either of these things will take considerable time. Writing a tutorial for either of them would also be a very time-consuming project, so don't ask me to write one for you. Good luck.

The problem is that a VOB is a container for information. That is all it is. It is a book without an index. All the information is in there, in this case all the streams; the subtitles (hard coded), the video, the audio track. It's all there. You can tear pages out of the book BUT you have nothing to guide you as to how to put them back. By the same token, you can put them back anyway you like. You can resync the audio track so it 'sounds' right. You can add a subtitle track which appears to display right...because it IS right...it is only a container; it can hold anything you want it to, in any order you decide.

Now, all glued back together, you settle down to enjoy your reconstruction only to discover that the original index, the catalogue of events of how the thing should be read, doesn't marry up with your 'fix'. How can it? YOU have changed the order of things to suit yourself.

The DVD structure is like a robot reading an instruction set. It was built to perform a particular function in a certain way. If you want it to perform differently then you also have to reprogram the instuctions so that it knows how perform the new task. You need to update the index to the new order of things and NOT just the contents of the container.

Just taking things out of the container then putting other things back will not confuse the machine.
You only succeed in confusing yourself.

Yes. Good luck, indeed. I wish you well.
