View Full Version : Wrong file size ripping single pgc from episodic disc

Took me some time to narrow this down but here it goes. I've ripped my original DVD of a TV show with 4 eps on it to hd in DVD Decrypter file mode. When I open the correct ifo in AutoGK the contents appear like this:

So pgcs 3-6 are the episodes which I select one by one and place in the queue with each ep targeted at 400 MB. AutoGK encodes each ep to an avi as it should, however the file size is around 560 MB per avi and the encode takes about 12 hours instead of 3!

So I ripped each ep seperately with DVDD in Ifo mode but again, when opening the ifo I got the same pgc selection as before. Only when I re-author each ep in DVD Shrink (a lot more time consuming than DVDD batch ripping) and then load it into AutoGK I get the correct file size and acceptable encoding time. How come?

Hi-

It looks to me like the single PGC 1 contains all 4 episodes. The rest of the PGCs have no size. That is, the episodes are not on the DVD twice, once all together and then again separately. In those cases decrypt using DVD Decrypter in IFO Mode, choose the PGC 1, but select only the correct chapters for each episode. For example, if there are 20 chapters, then each episode contains 5 of them (and if 21 chapters, don't count the last one). It'll save you the DVD Shrink step, get the job done in 3 hours instead of 12, and at the right size.

Usually with an episodic disk, the individual episodes will display in IFO mode similarly to the way they've displayed in AutoGK, at which point you can select the PGC instead of the appropriate chapters.

With the below image, I right-clicked on the Input window and selected Expand All:

In most cases all the episode PGS's will display under one VTS.

@manono

As you can see, the single eps DO have sizes other than 0. I've done a new rip on another episodic disc. This is how it looks in DVDD Ifo mode:

and this is how it looks in AutoGK after I ripped only PGC2:

which means, that it still will encode all PGCs instead of just the one selected.

So as a workaround I have to manually extract the pgc2 ep with DVD Shrink and only then load it into AutoGK.

I see no such thing. You want to see how large the PGCs for the individual episodes really are? Open the DVD in VobBlanker and have a look. All you've shown me are the lengths of each episode. The episodes themselves are all in the PGC1. The other PGCs just reference PGC1.

Yes it will, and I already gave you a better workaround than yours of using DVDShrink after getting the VOBs on the hard drive. And that's to decrypt the chapters corresponding to each episode from PGC1.

How can you tell from the screenshots in my previous posting?

You have but it does not work. Each episode has 5 chapters, when I rip chapters 6-10 in ifo mode I cannot open the ripped episode in PowerDVD, Shrink, PgcEdit.

Look at your screenshot of DVD Decrypter - all the episodes are under the same VTS. Look at mine just above - see how each episode is in its own VTS? That's how.

Try ripping the individual PGC's as I suggested - I've done it many, many times, and it has always been completely successful in separating episodes and outputting individually playable and encodable VOB files.

And to follow up on what CWR03 said, don't open the IFO, but the VOB(s) itself (themselves).

So what? I thought we were using AutoGK. Open the VOB(s) in AutoGK if the IFO won't open.

Now just stop and think a minute. Do you really think they're going to put the episodes on the DVD once all joined together and then again separately? Put the same thing on the DVD twice? The other PGCs besides the first one point to the correct chapter numbers within the first PGC. That way they can have both a "Play All" and a "Play Episode Whatever" in the menu.

Like I said before, when I rip PGC2 with DVDD it still shows up with all other PGCs in AutoGK and the resulting avi size is incorrect.

I thought we were using AutoGK. Open the VOB(s) in AutoGK if the IFO won't open.

If I go along with your suggestion, that is ripping (all streams of) the ep by chapters with DVDD I get the vobs BUT opened in AutoGK there are no subtitles.

Of course I did not assume they'd put the ep twice on the disc, I'm still wondering why I can't seem to rip them properly by ep.

If you ripped only one episode by its PGC and loaded the .VOB, it should be impossible for AutoGK to include all the episodes into one file, unless you ripped all the episodes individually but into one folder.

As far as the subtitles, you'll probably have to process them manually. AutoGK cannot properly handle episodic disks, so it's unreasonable to expect it to handle the subtitles. Another option would be to encode all the eps along with subs, then split them.

Correct me if I'm wrong about this (this thread is getting long now), but isn't this the first time subs have been mentioned? And you're burning the subs into the video? Or keeping them separate and external?

If you plan on burning the subs onto the video, then unless you prepare the subs for each episode yourself in advance (or find them online somewhere), the best way is to encode the whole thing (all the episodes) at once, and then split the episodes into pieces afterwards. That can present problems of its own, especially if the episodes end and/or begin with fades, because they may not split properly.

I'd suggest looking for subs at one of these sites:

http://www.divxstation.com
http://www.divxsubtitles.net
http://www.opensubtitles.org
http://www.subbiee.com
http://titles.box.sk

And if you find them, use the CTRL-F8 trick to add them to your episodes.

Chetwood is right. AutoGK definitely has a problem with VTSs which have more than one PGC. But, I don't know why Chetwood has a problem decrypting PGCs with DVDD.

Here is some example with VTS that has three PGCs which don't have shared cells:

http://img528.imageshack.us/img528/6117/dvddef9.png

First PGC is a main movie, second is a studio logo, and third is a trailer. If I choose first PGC in AutoGK, I get one AVI file with altogether movie, logo and trailer. But, if I demultiplex first PGC with DVDD, I'll get only main movie.

Sorry, been busy with RL.

I haven't mentioned subs yet because the issue came only up when I tried one of your suggestions which left me with a folder with ifo/vobs that cannot be opened by any other tool than AutoGK. And since I do own the original DVDs that I'm ripping from I prefer to get the sub from this source as well rather then searching the net for subs that might have been done on NTSC instead of PAL.

However, in this particular case AutoGK cannot even find the subs when I open the vob only. Do I open by ifo I'm getting a list of all pgcs and not just the one ep again. This seems to cause some problems cause the sub ripped from this ep starts 10 seconds into the movie instead of right at the beginning. Which is quite annoying since I set DVDD to reset time to 00:00:00 as well as VSrip (trying this one since AutoGK rips only 1 sub stream) to reset time at the first selected cell.

On top of that the resulting avis are suddenly smaller than selected. A setting of 400 MB target size results in 280 MB and a target size of 200 MB (20 min ep) shows up as 177 MB which is quite weird since I always select Fixed Width 720 (PAL). So let's sum up my problems with AutoGK and DVDD: I'm convert ep 2 from an episodic disc ripped as DVD-9 to my HD which appears in those programs as shown in my posting #4 (http://forum.doom9.org/showpost.php?p=1035948&postcount=4). I'm trying in this order:


AutoGK from the complete DVD-9: I open PGC2 but all eps are ripped into one avi

ripped ep 2 with DVD Shrink first

ripped pgc2 with DVDD first


In both latter cases the subtitle starts about 10 seconds too late when ripped with VSrip or Subripper. Playing back with PowerDVD however starts the subs correctly.

So, I'm at a loss here. I'd prefer to batch rip single PGCs with DVDD, then feed them to AutoGK but subtitles are off and file size is too small (encoding is 2:20 hours instead of 3+). How come?

You don't get subs when you open a VOB. You only get them when opening an IFO. Look, you have a somewhat unusual case there of all the episodes being in the same PGC. It's well known that AutoGK has trouble in such cases. There wouldn't be any trouble at all except for the fact that you want subs. You seem to know how to get the subs on your own, but the timings are off. So, add a delay to set them right again, and then use the CTRL-F8 trick to get them into the AVI.

The wrong size problem is sometimes caused by installing a newer version of XviD on top of an earlier version without uninstalling the older XviD first. I might suggest going into Add/Remove Programs to uninstall XviD and then install it again. No guarantees, though.

As I want external subs (idx+sub) I won't need to use CTRL-F8. However, since extracting them both with DVDD and DVD Shrink somehow results in an offset I'm gonna ask about this in the subs forum. Cause manually adjusting the delay is time consuming and often comes with unsatisfactory results.

Thanks a lot for the tip with reinstalling xvid though. Now that I did this with both AutoGK and xvid, the target files come with their proper sizes.

When you demultiplex a subtitle stream from a DVD folder with DVDD, you would get its offset in the file name after text DELAY.

Chetwood
24th September 2007, 06:54
Yep, I already thought about that too, thx. Also, when opening it in Subrip the offset is shown also. What still weirds me out that this offset is introduced in the first place, after all, it wasn't like that on previous rips and I still have set DVDD to reset the timecode to 0.
