Converting my VRD mpegs to Divx

[JohnC]

Since I've changed from 450 to 455 to 459 I've not been able to reliably get my mpegs from VRD w/QSF to convert to Divx using Divx's Converter program. The audio is almost always out of sync on my longer clips. The Divx Converter can usually handle the VOB's fine, but it won't handle the QSF's from those VOB's anymore. Also ... the Divx Converter also won't handle all my recently mpeg-joined videos from VRD. This was a 50-50 proposition even with 450, but it seems it's fallen to 0% now.

I've even tried keeping a separate version of 450 in a different directory, but that doesn't work anymore. Maybe the two VRD's are using a common registry setting? Anyway ... I'm looking for suggestions for a setting I could turn on/off in 459 that may help, or how to get 450 working again. Barring that I'd like to see if the VRD magicians would pony up the $30 to buy the Converter and try their hands at it, and see if they can find what may be causing it. :) I hope there not special code needed like there was for MovieFactory. :)

Thanks for your time.

What version of Divx converter are you using?

We "ponied up" quite a while ago and have not seen an AV sync issue. Version 6.1 installed

What is the source of the files you are joining?

What is the source of the VOBs that are creating an issue?

Pat - for a very brief period, DivX were giving away free licenses for their DivX create pro product ;-)

It was some kind of anniversary celebration, or something.

[phd]

The free license allows for updates.

Also they didn't include the MPEG decoder. You had to pay $10 for it.

>What version of Divx converter are you using?

The current 6.1

>What is the source of the files you are joining?
>What is the source of the VOBs that are creating an issue?

Source is some of my collection of DVD's I backed up using DVD Shrink. I decided to convert them to Divx and put them in one of these new HDD Jukebox's. If I repull the VOB's using Shrink, and run it through QSF first, the output will have A/V sync problems after using Divx Converter now that I'm at 459. I was running through QSF first because VRD would inspect the time of the VOB and say it was 10 minutes (or some such) instead of the 2 hours that it really is. The video still plays fine, and the Divx Converter doesn't have any problems with the VOB. Doubt it matters but ... when I use Shrink to make the backup I usually trim some from the beginning and ending credits.

Some of my collection have 2 disks for a video. I create a VOB of them using Shrink. Then create mpegs using VRD (without QSF), and then join those mpegs. They also have A/V sync problems after running through Divx Converter. I've even tried running QSF on the joined mpeg first.

By the way ... I noticed your reply was at 2:30 am. Do you ever sleep? :)

Thanks for you help.

[JohnC]

Opps. It's wasn't you that was up at 2 am ... it was Lester.

I might also add ... since you tried Divx Converter and didn't have any problems, that it may be related to some shared file or registry setting because at one time I had both 450 and 455 on my machine. I eventually gave that up when it seems neither would work consistently with Divx anymore.

Try this:

Use this method for combining your VOBs.
http://www.videoredo.com/HowTos/pdf/Combine%20VOBs.pdf

Then run QuickStream Fix on the VLST file.

[JohnC]

The process you mentions looks like it was made to combine the VOB's from a single DVD into one logical file before creating a mpeg. Right? Or does it combine the VOB's from multiple DVD videos?

I use the DVD Shrink feature that outputs the entire video into one output VOB. I do that for two video's and then I'm using VRD to create a mpeg from the two pieces, and then using VRD's join feature.

Sorry I didn't mention that earlier.

So unless it can combine VOB's from different DVD's I don't need to use VRD's "combine VOB's" feature.

John

[phd]

After combining the VOBs from each DVD, you can then join the 2 DVDs together using the Joiner.

[JohnC]

We're not communicating. Let's try this again. You said...

So unless this combine function you mention can combine VOB's from different DVD's it of no use to me.

What's the source of the DVDs / VOBs - are they commercial, or domestic DVD recordings?

[phd]

We are communicating fine.

Are you familiar with how DVD Shrink combined the 2 DVDs?

Do you know what modifications occurred to the 2 original DVDs that you had used DVD Shrink on previously? Did it maintain compatible settings to allow the recombination?

What program did you use to extract the original DVDs?

I am trying to remove variables here to determine whether or not some changes have occurred that are creating sync issues.

If VRD can combine your VOB individually and they play in-sync, then can join the 2 separate joined DVDs and play in-sync, then converting with Divx converter and they play in-sync, we know it may be an issue with how DVD Shrink will originally shrink, then reshrinks and combines files.

[JohnC]

Steps:

1. Months ago I backed-up the commerical DVDs I own, splitting some of the longer titles into 2 DVD's using DVD Shrink. I also usually use DVD Shrink to start after the credits and end before all the ending credits. There is no real 'shrink' when the title is split onto 2 separate DVD's.

2. I've now decided to convert them to Divx also so as to put them on a HDD Jukebox. Let's talk about those that were split into two DVD's. fyi .. I will be bringing out the orignals for these 2-DVD conversions, but I'm hoping my experience will help VRD.

3. Use DVD Shrink to rip disk 1 of the set. Use the option that outputs all the VOB's on the disk into 1 big VOB.

4. Use DVD Shrink to rip disk 2 of the set. Use the same option to output all the VOB's on the disk into 1 big VOB. I now have 2 big VOBs.

5. Use VRD to create a mpeg from VOB 1.

6. Use VRD to create a mepg from VOB 2.

7. Use VRD to join those 2 mpegs. At this point the mpeg plays fine in VRD.

8. Run Divx Converter 6.1. There are now A/V sync issues. At least the last handful I've done with 459.

Thanks,
John

How are you splitting the longer files into 2 DVDs with DVD Shrink?

Can you create 2 directories on the hard drive or you are burning them directly to DVDs?

[JohnC]

>How are you splitting the longer files into 2 DVDs with DVD Shrink?

The tool allows you to pick a starting and ending point. I pick something around the middle of the movie when there's a change in the plot.

>Can you create 2 directories on the hard drive or you are burning
>them directly to DVDs?

They go to two separate directories.

Thanks,
John

[JohnC]

Pat, is this problem being investigated or on anyone's list?

Early on I mentioned I'd had some success with mpegs from b450 converting to Divx ... before upgrading. I had put the b455 in a different directory and after wards even mpegs from b450 wouldn't convert to Divx. If I try to reinstall the b450 into another directory do you have any recommendations about settings/techniques/etc that may help this problem?

I'm just not convinced how this is a VideoReDo problem - can you expand on that?

I've converted 4 of my commercial DVDs to DivX to play on my PMP, this week. On all, I used VideoReDo to slightly trim the films before conversion, so VideoReDo was in the loop. None of them have any sync issues.

I'm running the current DivX codec, and either 460 or 461 of VideoReDo (at the time of using it for editing). I used DVDdecrpyter in IFO mode to extract the PGC / title of the main film to one VOB (for each film).

I then either QSF'd first, or simply edited the VOB by cutting off bits of wasted video at the beginning and end of each film, saved them as mpegs from VideoReDo, then queued them up in AutoGK.

None have any issues with sync - and practically all (if not completely all) the stuff I've converted to DivX has been edited with VideoReDo first, then converted, and I never have sync issues.

I can only think either it's how you are extracting the VOBs, or something in the conversion process is at fault, here.

[JohnC]

Hello Lester,

Glad to hear you're not having any problems. Good.

I've converted many mpegs from VRD to Divx without problem using my technique. I've 100+ movies in my collection. It wasn't until I put b455 on my machine at the same time as b450 that things started to go haywire. It was in a different directory but I feel somehow this screwed things up. Even after removing b455 the problems remain. I've since upgraded to b461 and the problem remains. I wish I could find a way to get rid of *ALL* remnants of VRD and start over. I've 'deinstalled' but there are always things in the registry that hang around. I don't suppose you'd like to throw caution to the wind and install b450/b455 in a different directory and see how that plays in your machine. Wanna join me in this melodrama? It's lonely out here. :)

The problem is being investigated. It takes a fair amount of time to process files through Divx. Hours upon hours, so it is a slow process. Divx is not the fastest horse in the race.

My version of Divx (6.1) does not seem to care for VOBs and disappears before encoding the whole movie. I have been incrementing the size of the files and saving segments without any AV sync issues. 1 hour cuts of the movies play fine.

[JohnC]

>The problem is being investigated.

Thank you.

>It takes a fair amount of time to process files through Divx.
>Hours upon hours, so it is a slow process.

:) Yes I know. I've got a dualcore AMD and it's usually a 1-1 ratio of time-of-movie to time-to-encode.

>My version of Divx (6.1) does not seem to care for VOBs and

I've seen that movie too. :)

>1 hour cuts of the movies play fine.

Lester also is not having a problem (Thanks Lester). This is goodness in that it shows there's hope at the end of the tunnel. :) Could it be that I'm at XP SP2? Don't forget my to scratch your head over the concern that it may be related to at one time having both b450 and b455 on my machine at the same time. Do you know of any way to really deinstall *all* of VRD, including most/all registry settings, so I can resinstall with b460 ?

You're lucky then :-)

My encodes (2-pass, using AutoGK) take considerably more than run-time. I would guess anywhere from 9 to 15 hours. I typically encode to DivX AVI, 160kbps mp3 audio, and typically 1100-1400kbps for video - so depending on length of the film, anywhere from around 1-1.5Gbytes for a movie.

I queue them up and leave them running.

That's on an aging PIII 1Ghz :-(

Still, does the job, just takes a while.

I'm on SP2, as well.

I've been encoding stuff for quite a while, although I don't do it all the time.

It's mainly just films or episodes from my own DVDs, or occasionally captured TV programmes.

So it had probably been a month or two since my last encodes, but this week I decide to encode a few movies from my library, that I didn't already have converted for my PMP.

There is a method using virtualdub, for playing with the audio sync, post encoding - leaving the video as is, and playing with the skew and interleave for the audio / video mux.

Please also try editing smaller clips with VRD of 1-1 1/2 hours to see if you also have AV sync problems with these shorter clips.

Have you contacted Divx to see about issues converting progressive scan video?

That's one of the things that AutoGk checks during the initial demuxing / indexing part.

It classifies the video content, and then decides if it needs to do anything about IVTC, deinterlacing, or pretty much leaving it as is from that perspective.

The analysis part is done through dgindex, then the results are analysed and further bits are done (compressibility test, audio conversion).

I've never used DivX convertor, though, so I'm not sure how it goes about it.

[JohnC]

>Please also try editing smaller clips with VRD of 1-1 1/2 hours

Used VRD to trim 3 clips .... 15, 30 and 60 minutes. The 15 and 30 converted using Divx Converter just fine. But at about 45 minutes through the 60 min clip the A/V started diverging.

>Have you contacted Divx to see about issues converting

Sorry no. Since I wasn't having (many) problems prior to adding b455 into a different directory I felt this was more of a VRD issue. I was hoping it was just a setting that would allow me to revert to the method that b450 used ... kind of like the Moviefactory setting VRD used to have. I've tried putting back b450 but it didn't seem to help. It's like b455 changed some registry setting that overrides b450 when I tried putting it back ... though I haven't tried putting b450 back again since b456 came out.

Sorry about that. The message was meant for JohnC since he is having issues with Divx, while testing continues.

Have you any mpegs that are unedited through VideoReDo that you could run through DivX convertor, that are of an appropriate length?

[JohnC]

>Have you any mpegs that are unedited through VideoReDo that
>you could run through DivX convertor, that are of an appropriate length?

Good idea ...hard to implement. I've got some DVD's around that were made prior to my purchase of VRD. But the mpegs are long gone. I could re-rip them, but to avoid contamintaing the test with VRD I'd need another tool to get the mpeg from their VOB's. Any freeware you know of?

DVDdecrypter - in IFO mode.

DVDFabdecrypter, then vob2mpg.

I suspect you just want anything that can parse the IFO(s) to create a linear VOB(s).

...to convert to Divx using Divx's Converter program. The audio is almost always out of sync on my longer clips.FWIW, I use Dr DivX and DivX Converter fairly regularly to re-encode various things, including VRD Plus output files from TS-mux captures.

Yesterday I tried using DivX Converter to encode a 1 hour documentary (output as usual from VRD Plus), and the audio was out by about 2 seconds by the end.
I did it again with Dr DivX, and all was OK. I used all the default settings for both programs.

I haven't yet looked into why this may have happened, but I will try a few more things at some point.

If it's a gradual loss of sync, it may be similar to that which blighted Virtualdub, before about June / July last year (RFF / TFF issues).

[JohnC]

Hello boys and girls,

And so the story of converting VRD mpegs to Divx continues. You may recall that Lester suggested to John to try a mpeg created by something other than VRD. Well ... what John has done is use DVDDecrypter to rip an old DVD he had of a TV show he taped a few years ago. He used the option to output into one large VOB instead of multiple little VOBs. So children ... what did he use to convert the VOB to mpeg ... well he used the same tool that Lester suggested ... VOB2MPG. The crowd moans "Oh my ... does this work!" "Yes", says John. It creates a file that is 1,106,837KB long. "Wow" says the smiling crowd. "But will it convert to Divx?" "Yes," says John. "And correctly, without A/V sync issues." "But wait", yells the crowd, "doesn't the mpeg created from that same VOB by VRD also convert to Divx?" The crowd holds it's collective breath. "No!", shouts an ever more depreseed John. "It creates a mpeg file of a longer length (1,107,161KB) and after Divx conversion has A/V sync issues to boot. Even though it does not have A/V sync issues when read by VRD. Alas ... maybe I should use QSF ... instead of just pulling the entire file." So sweet dream my little ones ... and tomorrow we will continue looking for an happy ending to our saga, and a moral to this story. :)

[DrP]

As a matter of interest, run the videoredo output file through pvastrumento or project-x and note any errors or comments made by them. Also, try running the videoredo output through dgindex and see if there is an offset in the audio file name. An mpeg player (including videoredo) won't care about the offset since it uses the time stamps in the file to play the file, but many xvid/divx converters do care.

pvastrumento (http://www.offeryn.de/dv.htm)
project-x and dgindex can both be downloaded from doom9 (http://www.doom9.org/index.html?/software.htm)

[JohnC]

DrP,

Ran the two mpegs thru pvastrumento. The first was the one that converted to Divx correctly. Here below it shows only 1 ALERT. The second mpeg was the one that did not convert correctly to Divx. It has 8 pairs of ALERT's. I'm no expert but that doesn't sound good. :)

As for Project-X .... the download for it doesn't even have instructions on how to run it. Just how to compile it. Looks like it should be called Project-in-Work :). While the second I can't find on doom9, but I'll look around.

Hi DrP,

Well I got around to using dgindex. I couldn't find it except as part of dgmpgdec, which is fine. Anyway ... I used "save project" on both mpeg files but could not find anything in the output files that looks like an error message. Is there something in particular you'd have me check for?

Thanks for yours ... and Lester's and Pat's help so far. :)

Those problems being reported by pvastrumento are possibly the same thing that I've raised in a thread in the beta section and might be the cause of your sync problem.

There's a compiled version of Project here

http://download.videohelp.com/~download/ProjectX_090.4.00.zip

from the VideoHelp.com site and a guide on how to use it can be found here

http://www.videohelp.com/guides.php?guideid=677#677

originally from Doom9. (It's not the friendliest of apps, is it!! I still try not to use it unless I have to.)

Good Luck in your quest.

But also remember that you need to have the Java Run time environment installed bfore you can run P.x

I can confirm what CharlesC is saying.

I think the fundamental problem is the MPEG-2 input plugin for Divx Converter is crap.

I always get out of sync Divx conversions using converter, while my conversions with DrDivx 2.0 (or Autogk) are perfect.

Hi JimmyB,

I think both VRD and Divx Converter need some work. I've had my share of problems with both. The pvastrumento tool I used to report on the mpeg stream seems to indicate errors in the VRD stream, but yet it works fine in all my mpeg2 viewers. I will look into using Dr Divx2 when they go to beta 9 ... since they said beta 8 still had A/V sync issues, though they did not say in what cases.

In many ways I'm surprised that creating/reading an internationally known standard mpeg2 stream is so difficult. I'd love to hear an explanation why this is so difficult to do.

Is your material NTSC or PAL?

Everything I'm reading, suggests to me that the conversion software you're using maybe falling foul of RFF / TFF type issues - which is something I initially encountered when first converting mpeg2 to DivX / AVI.

If you get the chance, try running a conversion through AutoGK (you can always uninstall it afterwards) - the current stable release is 2.27.

With VRD source, do you still have out-of-sync issues?

>Is your material NTSC or PAL?

NTSC. I'm in Texas.

>With VRD source, do you still have out-of-sync issues?

Yes. Nothing has changed.

>try running a conversion through AutoGK

Never used it. Can you tell me how it improves on the process?

That bit was out of context - I meant that to apply after trying a conversion through AutoGK.

Well I'm not sure about the semantics of the conversion software you're using - but the creeping of the sync issues you have, suggest it's field issues that are causing sync to drift the further into the encode you get.

As to how AutoGK improves the process, it will properly index the mpeg2 file at outset, deal with any audio offset during audio conversion, frameserver using the d2v file to encode the video, and interleave audio and video using virtualdubmod.

I'm just interested as to whether you still have the same issues, using an approach that I know goes about the conversion / encoding, in a valid manner.

It's not a huge install, and is easily uninstalled - it would just confirm whether it's something about the conversion process, or something about the source file that's causing the sync to drift.
