DVD unauthor

[Delta2]

Hi,

I ripped one DVD using DVD Decrypter and then I tried to make DVD Unauthor in order to make a MPEG of the main movie

I used a tool from DVDAuthor (sourceforge), but the resulting MPEG plays backwards and there is missing frames....very strange

How can I convert/unauthor a DVD to a MPEG-2 file with the main movie ?

thanks

thank you

I notice that VOB2MPG uses FFMPEG

is there a tutorial to make this conversion by my own in command line ?

something like :

FFMPEG -i *.VOB output.mpg

but don't know the syntax

Also try DGmpegDec.

thanks

I notice than FFMPEG is a very powerful tool, it does everything, but the documentation is HUGE and I can't understand

but how can I use it to combine multiple VOBs into a single MPEG-2 file, keeping same video/audio quality ?

[Delta2]

can't do it

this command doesn't work well, it stops converting at 1/4 of the job :

ffmpeg.exe -i VTS_03_1.VOB -i VTS_03_2.VOB -i VTS_03_3.VOB -f mpeg2video -sameq -ar 48000 -r 25 movie.mpg

can someone say what I'm making wrong ?

vob2mpg works fine, but I need FFMPEG

Womble Mpeg2vcr can also load vobs and save back as mpeg-2.

[deckard8]

ffmpeg.exe -i VTS_03_1.VOB -i VTS_03_2.VOB -i VTS_03_3.VOB -f mpeg2video -sameq -ar

Rip as one large vob instead of separate ones with Dvd Decrypter.

Why do you need ffmpeg when vob2mpg does the job for you?

Anyway: you need to concat the vobset before you use ffmpeg. So either

Rip as one large vob instead of separate ones with Dvd Decrypter.

or use

copy /b VTS_03_1.VOB + VTS_03_2.VOB + VTS_03_3.VOB VTS_03.mpg

Then use ffmpeg but not the params you tried or the whole thing will be reencoded and thus you will loose quality. Use

ffmpeg -i VTS_03.mpg -target dvd -vcodec copy -acodec copy output.mpg

as this will not touch the video or audio and will just iron out any timing issues brought about by joining the files in the first place.

Thank you very much, ChrissyBoy and you all

Thats was the trick : rip as one large vob

I managed to make it work with FFMPEG

it converts this large MPEG-2 file to AVI, very quickly

but I have this problem
