audio and video dropouts

[berndy2001]

Hello,

cause the dvd has multiangles, i stripped them with dvdremake (and some other useless stuff) and exported it.

than i've done a complete dvd-rb run, after rebuilding i burnt the result on dvd. on the pc with powerdvd: all fine. but on the SA i have audio and video dropouts.

first i thougt theese were readerrors, rebuilded and burnt again on a dvd+rw

dropouts were still there.

burnt the stripped material on a +rw (without the last vob-files, because too large), no dropouts!!!

upgraded today to .58 and rebuilded again, problem still there.

Next idea was, that the m2v's are defect. so i used dvd-lab to master some of them to a dvd. look very fine...

HELP!!!

you may noticed, i'm not a native speaker...

[jdobbs]

The dropouts went away when you burned to +RW? That sure sounds like a media problem.

[jdobbs]

By the way, my son is visiting Vienna this week. If you see a good looking American (who looks like he has a really cool Dad) walking around... tell him I said "Hi."

[Rockas]

@berndy2001

If u think that u will not recognise him (jdobb's son) just remember that he looks just like his father, well the eyes' colour is a little different :) :D :p :D :) :cool:

[berndy2001]

no, you misunterstood me. (or my english is too bad ;))

there are only dropouts, if i burn the output from RB on dvd.
the input (stripped material) works very well...

please tell your son, he should wear a t-shirt with "jdobbs's son" written on it. it will be easier to recognize him... :cool:

[berndy2001]

i just shrinked it sucessfully with dvdshrink, but i want to use dvd-rb...!

[Fr4nz]

Change your set-top player! :D

[jdobbs]

I think the "SCR difference..." thread may be getting me close to a solution for this. I'm working it. I don't know what's wrong yet, but I have enough information that I think I can find it.

[berndy2001]

just tried to rebuild with 0.59 and it doesn't work.

i also checked the result with the scr.exe, the errors are gone :confused:

the movie has Aramaic and Hebrew as language, so there are very much subtitles. does that matter?

[jdobbs]

No. Subtitles are so small that they hardly have an impact.

[berndy2001]

just encoded and rebuilded with 0.60, stutters are still there...

is there an other way (other program) to rebuild, (keep menu and subtitles)?

[Sir Didymus]

berndy,

There are a lot of beautiful other proggies for doing backups of dvds. Shrink is just one of them. Use google with "backup dvd" and you get more than 3.000.000 hints. You have just to choose the one which suits more your needs. In one of your previous posts you mentioned that you tested Shrink, but you were preferring DVD-RB. You have just to take a decision if you like DVD-RB or not...

In any case, don't you think it is just unpolite to ask in this forum, focused on the development of rebuilder, if someone knows some alternatives free of bugs (and maybe even freeware) ?

You'd better understanding that rebuilder is in beta testing. It means that some bugs are known, and are expected. Every contribution for making steps and improvements is welcome...

:rolleyes:

Ok. Let me stop here.

Please in the future remind this simple rule:
think before post.

[lamster]

What are you using as the encoder?

I'm using QuEnc; others have reported this problem with CCE. I don't see the problem if I use Rejig. Perhaps you can use that as a temporary solution until Rebuilder works properly even with these problematic stand-alone players.

(It might even be fixed in the next release; jdobbs mentioned a new change in the "Problem with DVD-RB and QuEnc on ntsc film sources" thread. I'm not going to get too excited about it, though, after being disappointed that the "Pack header SCR difference" fix did nothing for me...)

[jdobbs]

What problem with QuEnc are you having? (Not that I will get excited about it). BTW: A new version is posted with a QuEnc fix in it -- don't know if it applies to your problem.

Hi,

Stuttering like crazy on one stand-alone player; works fine on another and with software players.

I downloaded the new release within minutes of your having posted it, and have been rebuilding for over 5 hours so far. I'll know tomorrow if this is finally the fix that does it for me.

Thanks.

[marpada]

i have constant audio dropouts in The Simpsons Season 3 Disk 1 Z1 NTSC.
First three episodes sound good though ::confused:

I used Rebuilder 0.61, all versions before failed with overflow error during rebuild phase, for all 4 disks in the season.

I'm encoding with CCE 2.67.00.27, Avisynth 2.55

My player is Philips LX3000D, no dropout problems with previous versions. No dropout in software players.

Has anybody had this problem with v0.61 ?

[berndy2001]

i wont be unpolitely @Sir Didymus. i did not want to use another programm, i was asking for another solution.

@jdobbs: no, im useing cce 2.67.00.27 with eclcce 1.81

but i'll try QuEnc, may this helps... :cool:

(i only have pal-dvds to backup)

[Faust2]

@Berndy

maybe you should try this thread (http://forum.doom9.org/showthread.php?postid=548842)

maybe ask someone how exactly you must change the .ecl to turn off scene change detection??

[Sir Didymus]

@Faust2

Maybe some clarification is helpful on a simple test to carry out [drawback is that it requires to reencode, at least some cells, of the title].

The simplest way (reencoding the full title) is this one:

1. Put DVD-RB in three click mode, using CCE as encoder.
2. Run Prepare
3. Edit the file rebuilder.ecl, in the d2vavs folder, and change the entries of the cells you want to test from "fix_gop_length=0" into "fix_gop_length=1" in all, or in some specific [item] sections
4. Rebuild
5. VERIFY WITH VULEN that no errors are reported [if you reencode the whole title this step is easier, since no errors at all should be reported; if you reencoded just some parts of the title, this step is less obvious...]

Please consider that the procedure is just an experimental test, useful to collect information and feedbacks from people experiencing dropouts; nothing more [and please do not raise expectations on the matter...].

Cheers,
SD

[Faust2]

I for myself don't have any dropout issues; just wanted to make your findings a little more known :)

thanks anyway for the clarification; I hope somebody can test it out...

I think rebuilder is making really big steps these days...

/crossing fingers
:cool:

[berndy2001]

ok, just tested it.

with the standard-setting (fix_gop_length=0), vulen.exe found 4 errors in the first vob-file. one with 320ms.

with fix_gop_length=1, vulen.exe doesn't find any errors in all vob-files.

dont know, if the stutter should have gone now, but they are still there.

[jdobbs]

That establishes that at least in your case the runt VOBUs have no impact on stutter.

[jdobbs]

Have any of the "dropout people" tried version 0.67 yet? I'd like to get some feedback on the STD buffer changes I implemented.

[berndy2001]

//edit: thank you

[jdobbs]

@ berndy2001

Check your PM.

[berndy2001]

ok, just tested it with cce 1pass vbr, i'm sorry to say it, but dropout is still there. especially in chapter four.

movie: The Passion of the Christ
Player: Denon DVD-1400

[jdobbs]

Could you try using 2 pass VBR? There are lots of additional variables associated with 1 pass.

[berrani]

Hi Jdobbs, I'll test it as soon as you release it to public, early December (I've tested all last public version with my Pioneer 444, one with audio dropout problem :( ).


Thank for you great work :cool:

[psdos]

the passion of christ is the film i use to test RB with audio drops, i test with 1, 2, 3, 4 and 5 pass and gop_fix=1 in .ECL and the time 00:28:10 is presents audio drops.

[jdobbs]

Anywhere else? I'm not trying to fix one drop in one movie, that could be a discontinuity for all I know. I'm trying to see what impact the change in STD buffer allocation had.

[candsh]

I can't figure out why someone would use, to try out a program, versions in the early to mid 50's that were known to have the problems he is referring to when the lastest versions, that have addressed most of these problems are in the mid to late 60's and have even more features available. Am I missing something here

[Rockas]

All I can say is that I've made a backup of PASSION OF CHRIST AC3 only (region 2) and I got no problems with it :)

keep it UP

[candsh]

Concerning the drop outs all I can say is that I have not experienced any (none) problems with the back-ups I have done. But, I have never done any preprocessing of any kind and always used the current version. I almost feel like I should apologise for not having any problems, but, ........ I'm happy. Sent you a few extra bucks again. Thanks

[jdobbs]

Believe me, you are in the vast majority. The audio dropout problem is virtually non-existent. I have never experienced it and therefore can't even confirm that it is truly related to DVD-RB or some other part of the processing. I've heard it related to certain players, only to have others (including myself) find that it plays fine on those same players. 99% of all stutters relate back to cheap discs and go away if the exact same image is burned to another better quality disc.

But -- I want to make sure I address any reported problems so I continue to work on it. Because in some presented examples there is evidence to indicate DVD-RB is at fault.

It is, though, by no means something that the vast majority of DVD-RB users need to worry about. I know I don't.

[berndy2001]

ok, just burnt it on dvd (2 pass with cce), the stuttering at the beginning is gone away, but at the beginning of the fourth chapter (about 0:30:00) the stutter is still there. i also checked 0:28:10, yes, i also have stuttering there.

i don't think, the stutters are cause of bad quality discs. as i noticed this problem first time, i tried other discs and reencoded the movie again, 'cause i thougt there was a problem during encoding or burning.

but i have to say, this is the first and only movie in my collection where the stuttering exists.

[Rockas]

Ok... here's a solutions for all shutter problems and dropouts...

buy a 40€uros Denver DVD player :D

Ok, I admit I'm kidding but you can search the all forum and you'll never find any problem with DVD Rebuilder submited by me :)

Why? well I never bought a single "so called" good DVD player... the bad ones cost less (here in Portugal I've seen some on sale for 25€!?!?!?) have 2 years warranty (at least here in Portugal) and when they broke down... I can alway buy another... and they read everything I put on it :)

keep it UP

ps.
offtopic (SKINS) :)
@jdobbs
the VTS and STATUS boxes still don't get the size entered on the .txt files

[psdos]

Rockas it not true, i test with players of 40€ and have dropouts, so it not is the solution.

[Rockas]

Did you tested any recent Denver? (this is not advertise :))
I've done tests on four different models and they go just fine... I'm refereng to models of this year but I can tell you only the number of mine 438(mpeg 4 ;))... the other ones I don't know (my brother has two different and my sister another one but they don't live with me :( )

keep it UP

edit: sorry... the price of mine is 75€ - In Portugal

[jdobbs]

It seems that every time anyone mentions anything you have a problem with that one too. Have you tried working with a different burner?

[gizzin]

im sorry to say jdobbs your program is at fault, no offence not that you program is good. There are many people reporting dropouts usually with pioneer players. It probably has nothing to do with compliance of the DVD. I've done a encode a movie with 1pass all the audio dropouts where gone, but when i did a mutlipass they were present. This was with a previous version so this must say something.

[psdos]

@jdobbs

I test different burns and different mark of disc. There is very much films with audio drops, not only the passion of christ have problems.

[jdobbs]

@gizzin

I disagree. Define "many". I'd be surprised if you could go back through the DVD-RB posts and find 20 names of people who are experiencing dropouts. I use a Pioneer -- which was reported to experience "dropouts" and have never had one. Others have reported using Pioneer players without dropouts.

Why have so few reported it?

I can only speak to the current version. It fixed an issue that has been reported to fix it by others. If anything happened on an earlier version it no longer applies -- as it is yesterday's news.

I've spent an inordinate amount of time on this issue -- never once knowing if it is even real, only because I want to support the people who report problems -- even though the number of people reporting it was so extremely small.

[jdobbs]

@psdos

There are very many films that get dropouts "for you" -- that is not the same thing as "there are very much films with audio dropouts"

What brand of blank DVD do you use?

[gizzin]

sorry for my poor grammmar, i meant to say good program.

[KamikazeCJ]

Wow... great app Jdobbs. People like you making DVD backup a lot easier for wannabes like me. (Just in time for release of dual layer media too)hehe... Used to use you as a backup to DIF4U but finding to use you more. Done maybe close to a dozen now.
Anyway small talk aside, I ran across a stutter (or glitch) in the video "Matrix". Seems to happen around the areas of "Follow the white rabbit". (In both regular play and white rabbit play). The video has a brief pause (dropout) during BOV in area and area around re-entry into movie. Saw this thread for stuttering but don't know for sure if this classifies as that or maybe some seamless/nonseamless cell issue. I read where you used Matrix in your multiangle testing of V.65 Did you experience anything?
I did use Remake 2.6 something.
And only your public version 66a rebuilder. Not sure if 67 may have solved this?
Almost forgot... Playing this on a Sony dvp NC650V

[psdos]

With Shrink o CloneDVD2 same films all ok, but if you dont test passion of christ to say one, we will never solve this.

NOTE: There is more films, not only passion of christ. Disney films for example.

[gizzin]

jdobbs didnt you get cells with the present dropouts in them and the originals from sir didymus? isnt this enough proof?, is it possible that a simple thing like not having enough ram on your computer could cause a dropout because it isnt providing enough information during the rebuild phase (not talking about the std buffer thing). I have a 1.6gig p4 with 256megs or sdram. this is just an idea

[gizzin]

or = of

heh.

I have a 1.6gig p4 with 256megs or sdram. this is just an idea I may be mistaken, but I don't think Sir Didymus has ever experienced any dropouts either. He is working to help DVD-RB standardize against the DVD spec -- and that was the genesis of the fix that went into 0.67.

There are lots of reasons why you could get stutter -- most of which are not related to DVD-RB.

[Sir Didymus]

@gizzin

Hi, :)

Let me state clearly (once more time...) that I never recently experienced dropouts, so I didn't send anything concerning dropouts to Jdobbs.

I just reported in the past some formal infringements (SCR timings too short, VOBU min len too short, STD Buffer Overflows) with the hope that addressing something related to these subjects it was benefical for people experiencing dropouts.

My job (as beta tester) on all of these formal infringements is ended: I think I provided Jdobbs with the proper elements about these subjects, and I can not do anything other. To say the thruth my feeling is that I have been sometimes too pushing, and I am afraid for this, especially considering that all the backups I have done with DVD-RB are playing perfectly on the standalones of my family (I have just three available).

All I can say more is that it is evident to everybody that ALL of the reported infringements have been addressed by Jdobbs, and for the ones where the cure did not introduce new troubles to everybody for reducing the troubles of few people, Jdobbs cured them.

I sincerely doubt that. The O.S. takes care of memory allocation; if you don't have enough real memory, you'll just do a lot of swapping. If there's not enough swap space and a memory allocation request fails, then either the application checks the results of the allocation request and puts out an appropriate error message, or it doesn't, tries to use the NULL pointer, and crashes. I don't see any way that insufficient memory on your PC could lead to introducing stuttering in the rebuilt DVD data.

[psdos]

@jdobbs

Are you test with passion of christ? it dont work with Rebuilder or you want write a list of films with audio drops?

NOTE: in other post is the list, and your it dresses it

[jdobbs]

I've personally done the NTSC version of The Passion of the Christ with no problems.

[psdos]

You have a PM

[cbwarz]

Hi,

I guess i have bad luck :(

I have audio & video drops on Star Wars The Phantom Menace.

Done with:
* DVD-RB v0.6.7
* CCE SP 2.67.0.27
* SW Phantom Menace R4
* DVD Player Sony NC615

With previous versions of DVDRB i have more drops, now is less, but they are there :(

I have a feeling, note the word "feeling", that the audio 5.1 channels are doing the drops. When the sound has effects like volume high or something like that combined with other "thing" is when the drops arrise. But if audio is CBR then it isn't. Audio 1 is AC3 5.1, Audio 2,3 & 4 is AC3 Stereo.

All i have to say is: Sony Player in SALE. LOL.

Thanks jdobbs great program.

[KamikazeCJ]

Any possible solutions to my issue I listed above with "Matrix" ??http://forum.doom9.org/showthread.php?s=&postid=570058#post570058 (http://)

What exactly is meant by audio dropouts?
I've rebuilt several movies so far, and tested only on my PC.

How can I test if the rebuilt dvd is okay?

Test on a stand-alone DVD player. (Unless you're only making backups to play on your PC, in which case testing on the PC is sufficient.)

Listen to the audio. If you have dropouts, you'll know it.

[Rockas]

Listen to the audio. If you have dropouts, you'll know it.

Maybe you should listen the video :D

... sorry lamster... I just couldn't avoid this :)

[Kwark]

I don't have a SA player here, I watch most movies on my PC.
But when I go watch a rebuilt movie at my gf, is there a big chance that the dvd is bad?

If so, that would suck hard..
And it's still not known what causes these drops, and how to avoid them?

[Oldeman]

I used to have SEVERE audio dropouts using DVD-0RB and Quenc, but only on three different model Toshiba players. Not on my Apex 1500, Philips DVDR75 or on my PC software players.

On the Toshibas, the audio got completely out of Sync with the video and the result was unwatchable. You could start the movie at any point and in thirty seconds, the dropouts were VERY noticeable.

I have made several prior posts related to my Toshiba standalone audio dropouts.

Starting with version .60b, it was greatly improved and on ver .67 I can detect no audio dropouts on any of my players. As far as I can tell the audio dropout problems have been fixed.

Great job... JDobbs....

[TheSeeker]

@Kwark

What dvdrb version have you been using mostly? I think the worst ones for the dropouts are the low .6x versions. By .67 (the newest one) It sounds like the dropouts are gone for many. ALthough i have personally never seen dropouts on any of my backups. Well I take that back i saw them on one. The Deer Hunter. But that movie sucked so i didnt really care.

[bobkoure]

I finally got around to testing with my old-standby test DVD Van Helsing. (DVDRB .67, CCE 2.67, Panasonic DVD-R80)
There's a dropout within the first four or five minutes. Interestingly, the audio dropouts are simultaneous with lightning flashes, so the screen is going completely white for a flicker. I would have thought this was a player problem (too much data all at once as the entire screen was going from dark to white) but it does not exhibit it with the original disk. I do not see the audio decoder lights on my receiver flicker (as they did with the star wars disks encoded with DVDRB ... .64? - sorry forget the exact revision that that problem showed up). The audio dropouts are much shorter than with those previous SW ones, so maybe my receiver's indicators have more delay than the length of these dropouts.
Also, I am not observing (hearing?) dropouts when playing this re-encoded Van Helsing with WinDVD.
I plan to get to a couple of friends' houses to test against other set top players but have been overloaded at work - thought I'd post what I found even though I'm not done testing...

[jdobbs]

I've done the Van Helsing NTSC version with no problems.

[Rockas]

Any of you guys with dropout problems got a BenQ DVD recorder?
If you do try the book type change so that your recorded DVD get DVD-Rom format and then try them on your players... I think that should resolve your problems ;) - maybe this is possible with other recorders... check you manufacturer site :)

keep it UP

[erdoke]

@Rockas
I guess that book type bitsetting has nothing to do with possible dropout issues. If a standalone player won't recognize a DVD+R disc it simply won't play it. If it starts playing it, it should be OK throughout the whole playback.

[Rockas]

@erdoke
I'm just trying all the possibilities here... :)

Can anyone with dropouts just test it, please :)

keep it UP

[psdos]

I already found the solution for audio drops. Not to use Dvd-rb. Not another one, since his creator never has dropouts. It will be thing of my recorders, my discs, I am safe I. So there am I decide not to use it more. DVD+R DL powahhh

I don't want to question your knowledge on book type, but it is only a disc type marker. It has role only when starting playback (or never). If it was started succesfully, it becomes just a regular playback. ;) So setting a +R marker to a DVD-ROM marker is only useful when your standalone (or very old DVD-ROM drive) doesn't recognize the disc which tells of itself being a DVD+R.

[powerslave]

jdobbs: I had all sorts of problems with video dropouts with cce basic 2.69 versions. Finally went back to 2.67 one and it finally worked. With the 2.69 version, after watching the encoding going on, it seemed like during encoding of certain segments, the cce screen would just disappear before reaching 0 and the next segment would start to encode. Has anybody seen this kind of behavior in any cce version?

[TheSeeker]

I have seen alot of people have alot of different issues with the cce basic 2.69 version. It seems like that is the worst version of cce to use with DVDRB.

[homey]

Just to add my $.02. I was getting dropouts with previous versions of DVD-RB. With 0.67, I've backed up about a dozen DVDs and not a one has them. Only changed has been the version of DVD-RB. Same media. Same version of Avisynth, CCE, etc. The backups are pretty much flawless now.

Thanks, jdobbs!

HDC

[eriksen76]

The recent movies I did with version 0.66 worked flawless

But today I encoded another movie (no pre-processing)and there was numberous dropouts.

Very strange I think

/Julius

[gizzin]

This happened to me too but in a earlier version. I cant really remember the exact number but it was a above 60. I did a encode of Gang Related 1pass w/analysis it had no dropouts. Then i did a multipass encode of 7passes and it had the dropouts in the exact same places as the other encodes had of previous version. To me this should of indicated a possible reason for the dropouts but im not sure.

[Ngr]

Hi

I get audio dropouts on quite many dvds. These mostly occur on scene changes. It may be that i have a Pionner dv-535 and a 717. They dont occur on any of my pc dvd players.
Worst of these is in i,robot R2.
I am using cce trial 2.69.00.27, avisynth 2.5.5, dvdrb 0.67.
I dont get any dropout if i use dvdshrink, dvd2dvd-r.

[rocko1911]

Hello there,

I'm new to the forum, so hello everyone!

Have these audio / video dropouts only occured with multiangle movies??
Otherwise I will get myself a standalone and can provide additional testing (of my non-multiangle movies done with RB).

@jdobbs: Thanks for this nice proggy :) Keep up the good work.

CU,
Rocko

DVD-RB 0.64

you are right, in only have these problems with multiangle disks too.
just tried it with 0.68 (no matter, if cce or procoder used)

anyone other who can report this?

[f@chance]

Just to add my experience so that JDobbs can go on with this excellent proggy. With 0.64 I did Voyager season 3 and had a few drop outs (small audio glitches) on two disks but no loss of sync.

Did the donation thingy and have done now many back-ups with 0.67 and 0.68 and have not encountered any audio difficulties.

Same AVS, CCE, DVD Remake 2.54 no other changes

Just went from 0.64 to 0.68

SA player is a Sony DVP NS-930V

Maybe the answer is donation :)

[DVD Maniac]

Got my v0.68 yesterday and gave it a test drive with what has become my defacto Rebuilder test movie - Paycheck. I must have run every single Rebuilder version with this.

Well, I am pleased to report that FINALLY the audio drops have gone!

Brilliant! Fantastic!

I am going to run more tests, but I am cautiously confident that you have found the solutions jdobbs. Well done!

Congrates to Sir Didymous as I am sure his buffer test proggie helped in this final solution.

Well done to the Rebuilder Team :sly:

Sorry for the very late feedback to your important post. (Being off-line for some days...).

Your new is very cool, and I am very happy the problem seems being definitely solved. :) :) :)

I want to state my contribution has been very little, since I simply pointed out some formal infringement may had some relationship to the problem. Nothing more. So all the congratulations (adding some more on my side) should be directed to Jdobbs.

Hey, my friend, I like to give credit where credit is due... you were very instrumental in finding this glitch. Thanks.

[TCrowe]

As of .68 the audio dropouts have been fixed? Can others confirm?

Thanks...

[eriksen76]

I justed tested 0.68 on a movie which used to have lots of "stutter" in the beginning (first minute or so).

About 70% of the "stutter" is gone, but still some of it is there. So we're almost getting there now aren't we.

I guess it needs to be tweeked a bit more Jdobbs :)

Also tested version 0.68 on a movie that have had a "drop-out" in the exact same scene with previous versions. I am happy to anounce that the drop-out is GONE now.

Audio Drop has always been the consistent problem with my players(s) until v0.68. I don't think I have seen any video stutter problems simce it was "fixed" many versions ago. I was under the impression that any video errors had been sorted and it was audio drop that was the remaining bug?

I'll keep a look out on future results.

[jdobbs]

There are no video stutter errors of which I am aware.

You're right with version 0.68 I have not seen any video stutter so far. Only thing left is small audio stutter which has become even more rare with the new build.

Like I wrote ealier, one of my problematic "audio stutter movies" has left me like 30% of the audio stutter compared with previous DVDRB releases.

I can't figure what is is about your setup that make is so much worse than anyone else... what brand of player do you have?

One JVC and one Pioneer connected to my 4:3 tv. Nothing special.

Audio stutter almost gone but not quite.
With build 0.67 and ealier you could not have overlooked this error during watching the movie, but with 0.68 i might be possible, as its small glitches in sound. The problem might be that I know in which scene to look for it, and therefore I listen closely and finds it.

Not a major problem, but believe me, its there. I did a backup of my new LOTR ROTK SE, and there where no problems at all during the 4 hours. So the error is very rare. But I always test the new versions of DVDRB on previous problematic movies.

If you're able to tweek it a little further, then send me the build and I will do the testing right away. Could be 0.68a ::)

Hi...

I too can confirm that the audio drops are still there in 0.68, but as eriksen76 says they are much better than in previous releases of RB. where before they were very frequent, now they are less often and less noticable...

The player i have the problem on is made by Pioneer

What ever you have been doing seems to be correcting the problem...

[TheSeeker]

You all should try out version 0.69. seems there were even more SCR calculation corrections so maybe that will lessen the dropouts even further.

Thanks Seeker...

ill give it a try..!!!

[J-Wo]

hey guys, I'm really excited to give 0.69 a try. I've dropped out of the DVD-RB scene for months but the last major problem I was having was audio dropouts, so I'm excited to give this new version a try. Has anyone had success with pre-processing (i.e. using VobBlanker of PGCedit to blank out cells) and producing an audio stutter free DVD-RB output? That's where most of my problems came from before. I know you can always encode and build with RB first, then blank out the extras you don't want, but that makes output size prediction a little tricky.

Anyway I'm going to give things a go and see how the new version works...

Most people using it have done this, only a very small amount of users have reported the audio-dropout thingy at all.:)

Quoted. I am among the most... :)

[candsh]

I have never had a problem at all with audio/video drop-outs or stutering of any kind. I have a Pioneer DVD player and Burn with a Pioneer A06 and A08. One thing I do differently is I play all audio back through a Denon home theater Rec/amp. Never remove any of the DTS because my system handles it. If there were a problem it would show up immediately. I also have started using VOB Blanker to edit out some unwanted segments and have had no problems there either. I actually started doing this to TRY to create a problem but none showed up. Liked it so well that I have continued using Blanker, especially since Jdobbs mentioned the possibility of incorporating a similar type function into RB at some future time. Just don't seem to be able to create this problem even when I am trying to!! Might also mention the problem doesn't show up on other players I have tried, Go-Video, JVC, Sony, Apex

[eriksen76]

Listen carefully now Jdobbs............

All stutter seems gone now with version 0.69 - Just tested it on the movie which left me like 30% of the stutter with version 0.68

Incredible work!!!!!!!

[Ngr]

Great work JDobbs

I am always testing a few movies between each release. I,Robot which had more than 30 audio dropouts on several different parts of the movie, now i can only detect about 5. Thats a major improvement.

Thanks

Did you test this one with version 0.69 - This is the first time that I have got rid of all the stutter.

I thought all had the problem solved now

I haven't heard of any with "drop-outs" since version 068 - only "audio stutter". Which was solved for me with 0.69.

/Eriksen76

[Ngr]

@Eriksen76

I did test it with .69 but i think that what i refer to as drop outs may actually be stutters. Since english is not my native language i cannot be sure of the differentiation. What i experience is that at certain points in the movie(almost always the same), i momentarily loose sound. That lasts for a few millisecs i believe. Because the duration is so sort, i am not sure if the sound is gone completely or its just very low in volume. Could you please explain to me the difference between stutters and dropouts?

[J-Wo]

re: stutters vs. dropouts

I'd really like to know that definition as well. Based on your description Ngr, that sounds like an audio dropout. i.e. the sound literally "drops" out for a second or less. As if you pressed the mute button on then off. I assume a video/audio stutter occurs when there is a "hiccup" in the movie, i.e. a short repetition of a small segment of the film. Think of when your CD or record has a scratch and so "skips".

Personally I have never experienced stutters, only audio dropouts. I'm anxious to see the results of my 0.69 encode from last night, but I can't check til after work! :)

My definition (dont know if its right) is that the video drop outs are when the movie acts if there is a tiny scratch in the media and so "skips". Example: A man jumps into the water and when it splashes it acts as if i hit pause/resume very fast. So the audio is affected as well. Almost like a fast layer break. But as mentionend these errors are no longer there for me after version 0.68 was released.

Regarding the audio stutter the picture is not influenzed at all. It acts as you decribed before:
i.e. the sound literally "drops" out for a second or less. As if you pressed the mute button on then off.

I have not seen this error after version 0.69

Hope I explained myself in an understandable way...

That sounds right to me.

Studder is when both audio and video are affected (Slight jump or glitch in both picture and sound)

Audio drop out is when the audio cuts out for a fraction of a second but the video is unaffected.

I Did a 6pass encode with cce v2.67.00.23, Avisynth 2.5.5.0, Decoder v1.0.1.0. DVD rebuilder v69 (Thanks Jdobbs) is the one i used but it seems to have the same dropouts in the same place and it eventually causes the audio to be out of sync with the video. So do you think this buffer underun is the problem or does it just have to be tweaked more. It was tested on a Pioneer DV-434.

@Gizzin

I noticed the more passes you do the worst the dropouts are. There is no quality benfit to doing so many passes. Try doing 1+2. I think this will solve your dropout problem.

Strange. Ive never seen a patern in the number of passes vs. number of drop outs. But you might be right

Please let us know if it makes any differences for you.

What do you say Jdobbs??

/Eriksen76

[gizzin]

ya i've noticed that too, with a previous version along time ago i did a 1pass w/analysis of Gang Related R1 and it removed the dropouts completely. Btw erikson76 not stuttors in the video, dropouts of the audio for a couple miliseconds. I've never noticed any sort of video stuttor in any of my encodes.

[J-Wo]

Well I'm VERY happy to report that I am audio dropout free using v0.69! Used to get them all the time on older versions, and attributed it to my using the custom notch matrix and OPV encoding. But my recent test showed that was not the case, so I think 0.69 has definately solved the problem for me. I think I've decided that I get better quality from 2 pass VBR and the standard CCE matrix though... which is too bad cause it takes twice as long but I guess DVD-RB has converted me from OPV!

[Ngr]

After many experiments the past few weeks i am convinced that the audio dropouts( video is not affected) i experience are very much desktop player dependent. I have a pioneer dv-535 and dv-717 and they both excibit this behavior. But they are both manufactured the same year. Dv-717 was the top model of the year. I tried playing my problem dvds in a friends players (extremely cheap models, less than $150 each) and they played ok. I think that later players are much more relaxed in their parsing or whatever.

[gizzin]

I tried doing 1+2 passes on Summer Of Sam R1. Which i was hoping would remove the audio dropouts. But unfortunatly this didnt work this time.

[jdobbs]

@gizzin

You seem to have more troubles with this than anyone... and I suspect it is not related to what others have reported. I need to know some things:

1. What kind of player do you have?
2. Do you do any kind of pre or post processing?
3. What audio do you keep (Dolby 2.0, 5.1, DTS?)
4. Do you use any of the addon packages (RB-Opt, RB-Keeper, etc)
5. How many dropouts would you say you get per disc?
6. Is it only audio, or do you also see video hiccups?
7. Has your problem improved at all since v0.67?

[gizzin]

First off, I have a pioneer DV-343. I never do any pre-processing of movies. Depending on the DVD i usually only keep the DD5.1 but in the case of Summer of Sam R1 its the only track anyways. No I don't use any of the addon packages. In most cases there is usually only about 2-4 dropouts on a disc. Summer of Sam this is not the case there seems to be more. Just the audio I have problems with, I've never had any sort of video problems (With newer releases at least). V67 Of Rebuilder seems to reduced the number of dropouts in Summer Of Sam R1 since this is the only DVD I've been testing with almost every version. V68 and 69 the dropouts seem to be the same to me. Alot of the dropouts are in one location so it's generally easy to tell. Hope this helps in any way. One question for you, Have you completely eliminated the Buffer overflow or underflow error? or do you plan on it?

[gizzin]

Correction. I've never tested it with v68.

[jdobbs]

What version of CCE are you using?

[gizzin]

CCE SP 2.67.00.23 trial

[Lorek]

I'm getting Audio Drops on Neon Genesis Evangelion using

Rebuilder .69
Lite On Burner 16x DL
Tested on Playstation2 Dvd Player
Media TDK 8x 4.5gb
CCE V2.69.01.10
Works fine when I play it using PowerDVD on my PC but
not on my standalone.



1. What kind of player do you have?
I'm playing it on a Playstation 2

2. Do you do any kind of pre or post processing?
No

3. What audio do you keep (Dolby 2.0, 5.1, DTS?)
5.1

4. Do you use any of the addon packages (RB-Opt, RB-Keeper, etc)
No

5. How many dropouts would you say you get per disc?
40+, I only watched the movie halfway through.

6. Is it only audio, or do you also see video hiccups?
Its only Audio
