Sound sync problems

[maldrich]

I have ripped many svcds using dvdripper, dvdavi (?) <tmpgenc & Nero - but all have the same problem - beautiful picture but sound sync problems. Usually starts fine but within 2o mins is noticeable - by the end of the svcd really annoying - please please can anyone help??

I think I have finally figured this problem out. I was having the same problem. I started out basically using SEFY's guide. I used the following programs: Smartripper, DVD2AVI, TMPGEnc and Nero. My DVD ripped, served and encoded fine. The burn went also went well (make sure to use the newest NERO if you want FF in SVCD). But after a few minutes the audio started to lag very badly. So I tried everyone's RIP guides, from SEFY to LLAMA. None would rectify the sync problem. I even tried DEMUX and split with BBMPG and encoding with this same program. I also tried the newest TMPGEnc (version 2.5...I think)and two versions of DVD2AVI. Also I tried different OS's (NT, 2000, and XP).

Then it dawned on me. The difference between regular NTSC and film and the frame conversion. So instead I turned the "force film" off in DVD2AVI. Even though the preview said film (percent rate was greater than 95) and the frame rate is at 29 fps (NTSC). Once DVD2AVI was finished I encoded in TMPGEnc. But here is the important part. I used the NTSC template and did not....I repeat...did not use "inverse telecine". I also used DVDRIPGUIDES.COM's SVCD templates. So in a nutshell, I followed the above's rip guide...I just didn't "force film" and I didn't use "inverse telecine". This fixed my audio sync problem from begining to end. Last note.....keep both versions of DVD2AVI around (1.76 and 1.85). I found that sometimes I would have to use 1.76 because TMPGEnc would scream "unsupported file" when browsing to the *.d2v file. Once I used the older DVD2AVI frame serving it would allow the encoding.

The funny thing was it was the movie "Dude...where is my car?". This movie proved to be one of the toughest yet....

AlterEcho, out of curiasity, where is it my guide didn't work for you ? cause I don't use the Force Film, i avoid it at all costs

PS: I've ripped "Dude, where's my car?" was the smoothest movie, no probs!

First thing....I wanted to stress how much we appreciate the time and effort that you have put into the guides. If it hadn't been for your guides I would not have been able to even know where to begin.
The statement "cause I don't use the Force Film, i avoid it at all costs" made me think. I could have swore you had placed that in the newest guide. My mistake, you clearly state " Some movies may come in the Film format which is 23.976 fps instead of the regular NTSC 29.976, so you might want to enable the Force Film feature of DVD2AVI". I misread your statement. For some reason (probably after my sixth cup of coffee) I read it to mean force it into film mode when the DVD was greater than a certain percentage for film. Even if it was NTSC (29). Thanks for correcting me on that one. Again, thanks for the guides and taking the time to reply.

BTW...once I figured this out, "Dude" was a breeze. It just so happens that this movie was where I first saw this problem. LOL

To AlterEcho:

"keep both versions of DVD2AVI around (1.76 and 1.85). I found that sometimes I would have to use 1.76 because TMPGEnc would scream "unsupported file" when browsing to the *.d2v file. Once I used the older DVD2AVI frame serving it would allow the encoding."

Just for reference, the reason for this is:

The '*.vfp' files are version specific, when you run DVD2AVI it makes a registry entry to [HKEY_CURRENT_USER\Software\VFPlugin], so on my system if I first run my DVD2AVI v1.82 I find this at the above KEY:

"DVD2AVI"="C:\\Program Files\\DVD2AVI 1.82\\DVD2AVI.vfp"

Which now means TMPGEnc will only support '*.vfp' made with the above DVD2AVI.vfp. If I now load in a d2v file made from any other version of DVD2AVI into TMPGEnc I'll get the above warning.

So all anyone has to do is make sure that REG KEY points to the version of the VFP file used to make the d2v file BEFORE loading it into TMPGEnc. So if you run the DVD2AVI program used to make you D2V file this will work.

Hope that all makes sense.

I thought that DVD2AVI was having a problem within the plugin matrix of TMPGEnc....it had not occured to me that DVD2AVI had written to the registry. I hadn't had a chance to investigate any further and what you say makes total sense. Now I will not have to carry around both copies.

Thanks again

I'm glad to hear the problem is atleast solved
