demux from vob to m2v

[brucexx]

hi,

2 problems:

1. I am having a problem demuxing vob files. I am using TMPGEnc. I ripped DVD using AnyDVD which created 4 vob files with video. I am able to demux first vob file but the rest of them the TMPG shows video stream with no inforamtion while media info shows MPEG Video stream with additional inforamtion like 720X576 25 ffps etc. I forced it to demux by using De-multiplex option but it created the file with no extension (no .m2v). I manually added the extension but it did not do anything I still cannot play the file in any player (Media Player Classic tells me cannot render the file). Anybody's seen this thing before ????

2. My original problem was that after joining all the vobs and creating mpeg video (or playing the joined vob file) I wasn't getting 16:9 or any wide screen format. I tried multiple video players and always the same result. I am getting some of the movie in widescreen and the other part in 4:3 and all this within the same vob file. SO to clarify first 5 min of the movie plays 16:9 and next 25 in 4:3 within single vob file.

Has anybody seen this before ????


Thanks

1. DEmux with pgcdemux instead.

2. How do you join? Use vob2mpg.


And I'm moving you our video conversion section.

DgIndex: File -> Open (all 4 VOB files), File -> Save Project and Demux Video

thanks for suggestions. I tried the soft and it worked great.

Unfortunately I am still not able to play this video (in wide-screen) under any player (even the m2v stream).

Thanks again for you help I guess I need to read more about how pixels are represented (pixel aspect ratio) when the video is being played and how I can change it (if I can) or force it up manually etc.

regards.

Are you saying you can't play the M2V file at all or that it's just not widescreen?

PAL DVDs all use a 720x576 frame size. The difference between a 4:3 and 16:9 disc is just a flag in the VOB or IFO file that tell the player which aspect ratio it should be played at. The AR can change midstream.

A 4:3 DVD can contain a 16:9 movie by having black letterbox bars encoded into the frame. Ie, the frame is 720x576 but the movie only occupies about 720x432, the rest of the frame is padded with black borders. And movies wider than 16:9 will have letterbox bars regardless of whether they are encoded 4:3 or 16:9. A 2.4:1 movie on a 4:3 DVD will occupy about 720x340 of the frame, whereas the same movie on a 16:9 DVD will occupy about 720x428.

Many authoring programs will let you override the display aspect ratio setting to force 16:9 or 4:3 playback. You can use ReStream to change the DAR flag of an M2V file.

Thanks I was just researching I will give it a try!

I can play the m2v file it is just not in wide-screen. It is not really the truth it is wide screen for like 5 min and then it becomes

I also found the DVDpatcher that might accomplish this.

DVDpatcher worked like a dream - thanks a lot.
