transcode a single cell out of a DVD Title-Set or VOB file, the idea is to demux/split
the VOB file or Title-Set into its Cell-IDs, first.
Then we can easily access/edit/transcode a single Cell with any tool we like. I use ReMPEG2 to transcode movies, so simply transcode the demuxed Cell in that case. After that the transcoded m2v file can be remuxed back into the splitted Cell with VobEdit.
When that is done, we need to join the splitted Cells back to the orignal VOB file or Title-Set, to be able to process it further with IfoEdit, and so to burn it to DVD-R.
Below is a
detailed example, how to transcode the Cell Nr. 1 of Vob-ID-Nr. 3 from the
second Title-Set of the DVD: 'Final Fantasy Extras Disc'.
1. Demuxing/Splitting the original VOB file into its Cell-IDs.
2. Transcoding a single demuxed Cell-ID with ReMPEG2.
3. Remuxing a m2v file back into the demuxed Cell-ID/VOB file.
4. Joining the demuxed Cells back to a VOB file or Title-Set.
VOB file, that is containing the Cell you want to transcode with VobEdit.
In our case it's the file: VTS_02_1.VOB:
Button 'Demux', and the following dialog will apear:
would like to split a complete Title-Set into its VOB-IDs, then you could check
the last option.
If you don't check the last option, then only the current loaded VOB file will be processed.
clicking okay, you will be prompted to specify a destination directory
(Don't change the filename please!):
pressing 'Save', the demuxing/splitting begins:
is finished, your destination directory will look like this:
As you can
see, the filenames itself don't tell much about its content. That's why there's
also a log file.
with Notepad or any other editor to see, what we have in which file.
That's it for now.
can catch the VOB file containing the Cell, you want to transcode.
I'm going to transcode the Vob/Cell-ID 3/1, so lets open VTS_02_005.VOB with ReMPEG2:
the options, I'm using in ReMPEG2:
encode button, and specify a filename for the transcoded m2v file.
Now we are
ready remux the transcoded m2v file back into VTS_02_005.VOB.
VTS_02_005.VOB with VobEdit:
Menu-Item 'Remux m2v':
transcoded m2v file, in the filedialog:
filedialog apears, where you must select a destination directory, for the
remuxed VOB file
select a different directory and don't change the filename!:
got a transcoded VOB file:
Now we need to join all Cell-Vob files back to a regular VOB file(s).
back to your other folder and delete the un-transcoded VTS_02_005.VOB:
move the transcoded VTS_02_005.VOB, into this folder:
the first VOB file in this directory with VobEdit.
Menu-Option 'Join CellVob files' to join all files back to a regular VOB file(s):
have to specify a destination directory:
joining Process begins:
we've got a regular VOB file back:
forget, the VOB file has got changed, so some navigation pointers in the VOB
file aren't correct anymore, and some pointers in the original IFO file doesn't
point correctly too.
So if you
want to burn this to DVD-R, you must first process the IFO and this VOB file
with IfoEdit to correct the ifo-tables, and the vob-unit navigation pointers in
the VOB file itself.
