Audio offset - To DVD2SVCD

[24hourloop]

It looks like DVD2SVCD even with the latest BeSweet version has a problem with movies with an audio offset (where the AC3 track doesn't start immediately with the video). They are multiplexed as is and as such are slightly out of sync.

Doom's comments on the latest BeSweet version indicated that this was fixed in BeSweet but apparently it isn't (I don't ever seem to be able to find a summary of changes in the BeSweet zips).

Con somebody confirm or deny my observations?

please try this version:

Edit: now replaced by build 2

Have you ever used any of the pre-BeSweet versions?
If so have those worked for you?
Try a test and grab a 1.04 version to see if your audio is out of sync with it. If so it's probably a problem on your end.
I have had no Sync issues with any DVD2SVCD version with my Stand Alone Player or using WinDVD.
I have problems if I use Windows Media Player.

The audio is also manually adjustable. You can set a startup delay on either the video or audio to help with sync issues. If it is consistent then you could find the correct setting and always use that. I have not seen many posts concerning out of syc audio. This is the only reason I believe it might be something on your end.

Try the older version on a video you know you had problems with.

No, I haven't seen this before with the earlier versions but I may just not have run into it. (After all, I do not check everytime with DVD2AVI to see whether there is a difference).

This symptom is certainly not consistent. I have noticed it with this particular DVD and checked - there was the offset.

I wanted to download the package you indicated but the link does not work ...

[markrb]

Try this. Just had to mess with the link a little. DDOGG's must have somehow abreviated it.

EDIT:
It seems that the link is automatically abreviated. I had to remove the http:// for it to give the whole thing.

[24hourloop]

Thanks - got it - trying it out.

How can you say this mark?

with the amount of posts re: this issue that you yourself have responded to.

all the early 1.06 versions that used besweet have this out of sync audio problem. (1.06 build 1 - 1.06 b1 pre1 & pre2)

I can't comment on pre 8 or the new 1.06 build 2 because I went back to 1.05 build 4. I knew this worked for me.
I'll give the latest Version a try tonight.

[24hourloop]

I am not exactly sure of the nature of my problem. Using DVD2AVI I found an offset of 82msec. However, when I finally had corrected the mixing it turned out to be a good third of a second.

Maybe it was a bad rip. I am not sure. I used vstrip that hadn't failed me yet.

Anyhow, I downloaded the latest version (still trying it out) and I must say - nifty, nifty, nifty. All the latest and the greatest stuff in there and he has definitely listened to everybody's requests. Good job!

[markrb]

Most of the ones I saw where directly related to the bug that elimated some of the audio. There were a couple of posts related to out of sync, but nowhere near the amount related to the CCE crash/freeze issue that would make it more of a wide spread problem.
By the amount of post just concerning the out of sync audio and elimating all those related to Windows media player and the BeSweet issue with removing audio the numbers are relatively small.
This makes it seem more of a one time, a particular computer or DVD issue. That was the whole point of placing the ability to adjust the delays manually if a particular DVD gave you problems.

Now I am not saying it's not a bug or whatever, but if it is relatively few people are having this problem.

Slightly off topic -

I had an audio out of sync the other day, but it was like 10 seconds. Turned out it was the "This has been altered to fit your TV" black placard that came up (interlaced no less). That is the only time I have ever seen a problem. I flipped it over and did the widescreen version with no problems. Just something to stick in the mental databank.

This is one reason I look forward to a (maybe)future preview version that will allow setting a start point in the d2v easily.

I get the same audio offset error. The movie I have is the ususal suspects, widescreen version. when I play the original DVD a 'polygram - filmed entertainment' logo pops up, and then music starts AFTER the logo disappears. When I play the muxed file mpg the music starts at the same time as the logo, and so the audio is ahead by about 15 seconds for the rest of the movie.

oh, and Im not playin the mpg in mediaplayer. and Ive used the latest versions, both build 2 and 3 actually.

How can I fix this? is there a way to easily re-sync the out of sync mpg file, and then just load the mpg into nero and burn?
(I remember I once used a program for divx that would just loop a small portion of the film over and over again, and you just adjusted a little slider untill the sound and video matched up)

I think maybe Ill try the pre-8 versio tonight. whatever that is.
thanks.

After loading crash recovery file, change the startup delay in the bbMPEG tab and resume from muxing.

It may take a couple of trys to get the correct number, but it works and it's quicker than re-encoding the entire movie.

Good Luck

it is now fixed in v1.2b1 (http://dspguru.notrace.dk/BeSweetv1.2b1.zip).

[pool]

great. Ill try v1.2b1 tonight. thanks.

[pool]

okay. I tried besweet v1.2b1 . I still get the exact same audio sync problem :(

[24hourloop]

I had the same problem. I don't quite recall whether I used internal ripping or vstrip but using the opposite ripper fixed the problem for me.

[pool]

hmmmm. I used internal routines for ripping. but i wouldnt think that would change anything since the vob files dont have sync problems. am i right?

oh well, I eventually loaded the crash recovery and resumed from muxing like marks430 said, manually adding the audio delay in the bbmpeg tag untill I got it right.

But now the beginning of the 2nd muxed mpg is messed up. The first 8.5 seconds (same time I set the delay to) have no audio, followed by some jitters in the video. oh well, this i can live with.

I had the same problem because of the "this movie has been altered to fit your TV" placard at the begining of Princess Bride. The placard ran for about 7.5 seconds (based on the DVD player counter). I used the crash recovery tab, and started again at Muxing and cutting. With DVD2SVCD set to advanced I adjusted the audio delay in bbMPEG to 8830 (instead of 180).

I think the result is pretty close to perfect. I got a good result on the 2nd attempt but, it took a few more tries to get it perfect. On my machine (P4 2.53 GHZ) each redo took about 10mins. so it's not too big of a deal to correct this manually. I would've gotten it fixed faster if I had made the changes before loading the d2v recovery file DUH! If on the next version the author of DVD2SVCD would want to automate this audio delay repair process I wouldn't mind though. :D

One small problem with the above method is that on the 2nd disk I loose about 5 seconds of audio at the begining, but then it picks right up and is right in sync. Log to follow.

My log file is too large for the post. I will attach it if anyone wants to see it.

Dont post in an old thread if your having a problem, make a new thread and also dont post your log file you need to copy and paste it in the thread.
We changed the forum since last year, all problem posts go in dvd2svcdbasic section. So make a new thread in there.
