convert vob to mpg

[Vidster]

I am using Mac osX and while I easily ripped vob files from a dvd (using dvdbackup) onto the Mac... I am having trouble finding an easy way, or any way, to convert these to mpg (mpg1 prefer, for vcd). I have QT6 (not pro) and it's of no use and Toast, which does not seem to encode these vob files for vcd.... Hope someone can shed some light on here for me.

Thanx, the Vidster

Neither Quicktime nor Toast will convert vob files. To convert them you should use ffmpegX. It is a free download and can be found on version tracker.

Use a demuxer (bbDemux) to seperate the audio, video, and padding streams from a vob (the padding is discarded by the demuxer).

Then remux (ffmpegX or MMT) the audio and video to get a standard mpeg.

Note: most vob files will be mpeg2

If you have the original dvd, you can use it directly with 42 to convert to vcd.

Alternatively, use toast to creat a dvd image from vob folder then use 42.

Hope this helps.

Well, I have been playing with ffmpegX and while I got an mpg out of it, the audio & video are out of sync. I also burned a vcd with a bin file besides.... it was a mess on the tv... lol.

What is this "42"?? I will try it. Yes I can do it right from the dvd since that is what I plan on doing if possible.

Thanx again.

you can find forty-two at
homepage.mac.com/kaicherry

its a great program! and will do direct dvd to vcd for you.
IF you find this not working (lately for me its been saying cant detect .ac3 fileformat for my dvd's and wont process them at all!)

you can use OSeX just like you did, but switch it to elementary stream, which will give you a .m2v (video file, mpeg2 format) and a .ac3 (audio file)

You can use various programs to turn these individual files into vcd.

Well, I have tried forty-two now and no go. I did everything by the book and the mgs it encodes for vcd are 320x240, not the compliant 352x240, so Toast will not accept that, and I also had to use mpgtx to divide the big file. So I tried to burn the iso file and it all worked til I put THAT in my dvd player.... was a mess. It stopped intermittantly & also the audio was messed up...

Any ideas? I am mostly curious why i got the 320x240 useless resolution for the mpgs.... If they would have been the rite size, everything would be perfect...

I am waiting for a response from forty-two's creator as well.

Thanx for the help. Any insight would be appreciated, as I am noplace yet... lol.

well i have never bothered to actually burn the VCD output from forty-two, but i dont think we we're ever alerted to a problem with improper size for VCD video, we'll take a look at it, word to the wise though if you used the word "worthless" at any point in your email to kai (Which you did in this post about the size it generated) i dont think your going to get a hasty reply to your query. As of yet though this is a problem that we have not heard of (at least i personally havent) we'll be making some revisions to the program in the near future. -- on that note i have finally added an auto bitrate calculation for DVD->DVD mode so that will give people an idea of at least one thing to look forward to.

[Vidster]

First off, to clarify, I did not use the word worthless. I used the word useless. Also, I was not implying that to the program, but the output of a file to 320x240, which is pretty much useless. If there was a radio button for that, then at least the ability is there to use that size if you wanted to, but I was surprised to find that outcome from the VCD radio button choice.

As for the program itself, forty-two seems to work great and efficiently, and probably does so for all other choices, except VCD it would seem. I don't really see how this could be a problem from my system in any way, however, I hope it is and hope I could easily fix that. If it is a problem with the program, it will be that much greater when it is solved.

I am mereley sharing my situation in the hopes of finding the easiest way to accomplish this goal so as to learn for myself and help anyone else who might be interested in the same.

And no I didn't use "worthless" or "useless" in my email... lol. As I mentioned, I was in no way referring to forty-two. I think it is incredible that individuals build these programs to help others. So far, with forty-two, I am closest to do what I set out to. In the future, I am hoping to see an interface in that app to split the output file as well. This would make it the absolute ultimate... unless there is a way already that I have missed.

Sorry for the book here, but I hope you know where I was coming from. Never meant any offence.

Thanx, Vidster

sorry i have a short temper, i tend to fly off the handle very easily sometimes.. there are just certain things that really irk me after hearing them so many times so occasionally i take them out of context. I just ran a VCD test and it came out 352x240. If you are looking at the size in quicktime then it would make sense that it says 320x240 because quicktime is retarded It was 320x240 for this movie too, but mpgtx reports 352x240. I did just notice that toast doesnt accept the video as vcd ready, but thats because toast is picky, if made into a bin file your mpeg probably would have been fine. And 42 is supposed to actually split and do that for you. I can see the reason for your misunderstanding, all the pieces point towards it not being VCD ready. But in all actuality it is, just not toast vcd ready.

[Vidster]

No prob. I understand. Makes it crazy sometimes when you know a lot about things and need to help educate others.... especially over & over & over... lol.

Well, I think I mentioned that 42 did also make the iso file... and toast accepted it, but it would not work after.... it was skipping and sound was all off, etc. That was on the stand alone... the movie was kinda in slo mo,... lol. vlc seems to play it. Although, at the end of toast burning that iso as a vcd, it stated an error of some kind... I forget what it said.

I am trying ff again right now and also 42... will let u know what happens this time...

Thanx again,

Vidster
