Ripping DVD Help and Explanation

[Excelsior123]

I see when you rip a DVD you can get output in two ways:


1)VOB, BUP,IFO

2) dtv,evt,vob,wav


What is the difference?

What is the advantage to each one?

Can output#1 be converted to output#2 and vice versa???


Next question, I want to use TMPGenc to lower the bitrate from the ripped file. (I want to squeeze a few extra files on a DVD)

Is TMPGenc the best way to do this?

What is the best way to do this that would then convert them to a mpeg2(DVD compliant file)?

If you end goal is simply to back up a commercial DVD, then there are some simple tools to do this.

1. DVD Decrypter or DVD Fab Decrypter to rip the contents to your hard drive. DVD Decrypter isn't updated anymore, so doesn't handle the latest copy protection. However it will still rip 98% of disks, is reliable, and has a great burning engine built in. DVD Fab decrypter picks up where the old decrypter left off as far as keeping up the latest protection attempts.

2. DVD Shrink can be used to remove unneeded features, audio tracks and subtitle streams, and to recompress the remaining files to fit on a single layer disk. Often you will find that by using the re-author mode and keeping just the main movie, you may not need to recompress at all, or only a little.

3. For disks that really need to be squeezed, DVD Rebuilder can use HCEnc, CCE or Procoder to properly re-encode the data to fit. It does not recognise tmpgenc.

These tools are the simplest to use to back up disks, although there are many others around. All of these are free (although CCE and Procoder are not)

I don't know what a dvt or evt is, however I think you are trying to describe the more complex methods, which involve extracting the elementary streams from the DVD structure (audio and video - mpv, mp2, AC3 DTS etc). While there are some circumstances where you might want to go down this track (if you wish to edit the contents or replace audio tracks etc), it is not for the faint-hearted. You will also have to be able to author these elements back into a compliant disk to use them again.

If backing up is the main goal, stick with the dedicated tools listed in points 1 - 3, at least until you have a good handle on how DVD works.

I really want to use TMPGenc to rencode my videos from the these two outputs that I have gotten of:

1)VOB, BUP,IFO

2) dtv,evt,vob,wav


Is there a tutorial on this?

Or

can anyone give step by step details on how to lower the bitrate using this tool, so I can put several unrelated mpg2 DVDs on one DVD (I don't believe I can do this with DVD shrink. MY understanding is it shrinks just one DVD that you are working with, not several DVDs.)

I have used TMGenc before, so I am imformed on its basic functions.

Can anyone help?

If you use he reauthor feature of DVDShrink, several DVD's can be shrunk down to one.

How would I use TMPenc to shrink the video down to lower bitrates?

[guns1inger]

You would have to use something like rejig to demux the audio and video back to streams (again, I have no idea where you are getting dtv and evt from). You would load up the video stream into tmpgenc, enter the correct bitrate settings, start the encode, wait twelve hours, then use the new video stream and the original audio stream to author a new disk.

If you are combining several movies onto one disk, don't forget to calculate a correct bitrate for the total runtime.

This question is rhetorical. If you had, you'd know how to do this. But I'll ask it anyway ...

Tried the guides section ?




All you gotta do is set the bitrate lower and ...... <* poof *> ...... video has lower bitrate. Quite magical really


http://members.dodo.net.au/~jimmalenko/AVI2DVD.htm and http://members.dodo.net.au/~jimmalenko/TMPGEnc1CD.htm might help, as the way I'd do it is to use DVD2AVI (now DGMPGDec AFAIK) to create a d2v file from your VOB files and to demux the audio. Then open the d2v file in TMPGEnc and re-encode just the video to DVD-compliant MPEG-2. Then author a new DVD using the M2V file TMPGEnc produced and the demuxed audio.


BTW please don't bump your post after only a few hours; This isn't IRC and it's annoying.
