Movie offset seconds

[xabat]

I would like to know where this option lies in the program BBmpeg.

The reason why is because I have a capture card, and I use it to convert my home videos to VCD. I have tried SVCD, but they went out of sync. Untill i tried converting a DVD with DVD2SVCD.

And as explained in DVD2SVCD ">0 is recommended. It can solve desync on DVD players"

But in bbMPEG i can't seem to find where this option is. It would be very nice to be able to make my home videos in SVCD instead of VCD ;).

One last thing....

How to use bbMPEG what ever I drag into the program to multiplex, it seems to refuse it :(

Go to settings in bbmpeg/program stream setting amd at the bottom is video/audio startup delay. 1000= 1 second.
:D

[xabat]

No I am not talking about the audio/video startup delay's...

There is a function in DVD2SVCD called "Movie Offset Seconds". It says it can solve desync on DVD players.

My movies go desync for about 25 - 30 min in the movie. But I can pause and then it is Sync again.

What will I gain if I set the Movie Offset Seconds to 5 instead of 2???

Most of times, this problem happens when you use IAuthor with chapters. It can happen with vcdxdbuild also. BBmpeg settings cannot solve it. There are 2 options for you:

1) use vcdimager to make cd images. There will not be chapter selection, but this async issue will be solved;

2) use 2 cds if the movie has up to 90min time length, 3 cds if it is up to 135min and 4 cds if it is up to 180min. This means, use almost up to 45min for each cd. Maybe your player don't handle properly cds with more than 50min of movie.

Sadly you could be right....

YES when using Iauthor with chapters, Bye Bye sync ;)

I never use DVD2SVCD to make images, only MPG files, and then I burn them With NERO 5.5.6.4

But about that whole 50 min max on each CD. You could also be right about that. Because Some movies stays sync, and I have just looked at the length at these movies that stays sync. AND WELL they are under 100 min. ;) BUT.. that logic gets screwed if I use any other audio than 224 bit rate.

Just some info my DVD player always shows 39.40 min or so, when playing SVCD....

WHAT I don't understand... HOW do you know that some players can't handle movies with more than 50 min on a CD. What about the movies you buy. I mean, the player says it can play SVCD, and I am keeping the standard even if i put 60 min on a CD...

Will it help if I increase the Movie Offset Seconds to 5 sec???...

As I said in my last post, bbmpeg settings cannot help you - the movie offset is between these settings.

My player (Philco PV2100, OEM of Skyworth 850) has exactly the same behaviour of yours, and some other guys here had reported the same thing. Looks like APEX owners have better luck.

To close this question.. YES YOU ARE RIGHT..

Just tried watching a SVCD movie on 80 min. after 50 min it went out off sync.. :(.

But one thing I can't understand is.. Why do my DVD play display 39:40 min nomather what the real size of the min on the CD is..

And as it can play 50 min without going out of sync, shouldent it display 49:40 instead, that would have made more sense..


Please help me out one last time ;)

Well, I have a theory - just a theory:

In the SVCD spec, a cd of 74min should have at least almost 37 minutes of movie. This means that a cd of 80min should have at least almost 40 minutes. My theory is the following: when the SVCD compatible player loads the media, it reads the Table of Contents (TOC) and recognizes the disc as SVCD, which "should" have only (almost) 40min of movie. Most bigger than this time, most difficult to sustain the sync.

[xabat]

But if you are right after 40 min it will get out off sync, but the human eye wont see it before about 10 min after..

How many min do you put on a SVCD so that you think it will stay synced ??

I have a movie with 48 min on one CD, and it do not look like it goes out of sync, but another movie with about 57 minon one CD, it realy gets bad....

my movies also gets desynced after 25´-30 minutes =(.. any solution ?
the strange thing is that this onky happens to some movies..

Very old post, old problem ... but my problem. I have also the audio desync issue. Along the movie, I can be a small one (few 100 ms, but you feel it) or more than 1 second. I have NOT made extensive tests, so I can NOT confirm that :
. the 2 sec offset in bbMPEG settings has no influence on this problem (">0 is recommended. It can solve desync on DVD players" ?).
. it becomes worse with the time, much worser after 25-30 sec.
. reset of problem when paused.Most of times, this problem happens when you use IAuthor with chapters. It can happen with vcdxdbuild also. BBmpeg settings cannot solve it. There are 2 options for you:

1) use vcdimager to make cd images. There will not be chapter selection, but this async issue will be solved;

2) use 2 cds if the movie has up to 90min time length, 3 cds if it is up to 135min and 4 cds if it is up to 180min. This means, use almost up to 45min for each cd. Maybe your player don't handle properly cds with more than 50min of movie.
. I have used I-Author and VCDXBuild with chapters :
. In both cases, I used I-Author muxer before Authoring (it solves other issues on my Pioneer DV-444), but I don't think this has some influence on this problem.
. The strange thing is that while playing the CD without any sync issue on PowerDVD, the problem always happens on my Pioneer DV-444. Video and audio play OK separately, but with a delay slightly varying with time.
. Going directly to the problematic chapters (Next button or direct selection) always showed similar offsets.
. I made a test with only 2 problematic chapters (5' video). Even in this case (<< 25'), the problem is still present on the second chapter. Much less (100 ms skew instead of 1 s), but still there (noticable because it is a scene with a speaker talking very fast).

So, any news on this subject since Mozart last statement ?
. any new settings for miracle solution ?
. why is the problem happening on standalone DVD player and not on software DVD player ?
. is the only solution the dilemma : chapters or sync problems ?

I missed this one from Xabat in http://forum.doom9.org/showthread.php?s=&threadid=11318. Same approach than Gerti67. I will try it, but as I am using I-Author muxer, I wonder if bbMPEG parameters are used while muxing and cutting BEFORE remuxing with I-Author or not. Otherwise, this is not a solution for me.
The Solution To Svcd Sync!!!!.. For Real!!!

I have finally found the answer to get a SVCD sync on a standalone DVD player!!!....

I have a Nintaus and this player was supposed to play anything, but I had huge problems with SVCD

BUT HERE IS THE SOLUTION TO ALL OF YOU HAVING THE SAME STUPID PROBLEM!!

The solution is to mux it right with bbMPEG..

I have just burned 60 min on a CD, and my player still only shows 40 min... BUT THE MOVIE STAYS SYNCED....

the secret is:

set the startup delay to 230 in video and audio in the bbMPEG setting, and your SVCD will be forever synced...

This is a solution I think many of you will be glad to see!!!


Now you think "yeah right, but then it is out of sync on my computer" NO IT'S NOT

I ran the movie on my DVD player, and at the same time on my computer, and they stayed exactly the same!!!.....


This is just to awsome!!...

I do not know why this solve the problem, and why it works with 230 or maybe more!!!.. BUT IT DOES...

in http://forum.doom9.org/showthread.php?s=&threadid=12901, another member had success with its Toshiba sd-1300 using Roxio Videopack. I will sure not use that SW, but the interesting comment in this thread is :I have noticed videopack creates svcds with the mpegav directoryI remember that DVD2SVCD is offerening this option somewhere. Maybe another investigation path.
