Title: Need good VOB > MPG converter
Post by: vanark on February 19, 2011, 04:14:50 PM

I've been using MPG2Cut2 with good success, but I came across a DVD today that MPG2Cut2 reported an invalid audio format.

Error message is:

Quote

Audio format not supported.
RC=32
Format=1 Bits=16 Ch=0 Freq=48000/s Align=0 AvgBps=1024000 RC=32

 
Anyone have a suggestion on a free (or trial that isn't hamstrung) tool?  I downloaded WinAVI converter which converted the entire DVD to MPEG and then MPG2Cut2 had no issue with it, but the trial version has a big watermark in the middle of the screen.  I used VLC to convert it, but the quality was terrible.

I'd like to maintain as much quality as possible for uploading to Youtube.

Or maybe someone knows how to solve the issue with MPG2Cut2?

Mpegstreamclip will do it and much more for free.

Why would you want to "convert" (transcode) the VOB files to MPEG? They *are* already MPEG-2 program streams. You could just concatenate the individual files to one big file which has the file extension MPEG. (E.g. via the CLI commands `cat` (Unix) or `type` (Windows).)

The only downside is that you will lose the DVD chapter marks when doing so.

I want to make clips of individual songs from a DVD.  One long MPG file is an interim step.  Making the 5-10 min. clip is what I need as the result.  MPG or AVI, I guess I don't care as long as the quality remains as high as possible.  Mpg2Cut2 works great for that most of the time, but I have this one DVD it is balking at.

I'm a tech guy and I could not get that one to work on my computer, even after installing, uninstalling quicktime and then installing the QT alternative.

 Are you using windows? I've had a lot of success with mpeg streamclip for mac. I think I've also used handbrake before on my mac. Sorry I can't help much if its windows. I'm a little shocked mpeg streamclip didn't work for you, its been very reliable for me, but again the mac version.

A couple of tools come to mind.

If you want to demux the vob to elementary streams so you can do that with pgcDemux easily:

If you wanted a full re-encode, Handbrake can do this well and you can also tell it to encode only specific chapters:

Another very simple/good encoder is ripbot264:

there are tons of free tools on videohelp.com depending on what your end goal is.

VOB => MPEG-2

Code: [Select]

D:\test>type VTS_01_1.VOB VTS_01_2.VOB VTS_01_3.VOB > merged.MPEG
VTS_01_1.VOB
VTS_01_2.VOB
VTS_01_3.VOB
D:\test>

For frame accurate cutting I use a combination of ProjectX (for demuxing) and Cuttermaran (for cutting the individual streams).
Both tools are free, Cuttermaran is even Open Source (Java source code which first needs to be compiled).

Handbrake or ffmpeg can be used for further conversion steps.
