I use TMPGenc to convert avi's to vcds. My Vcd's work fine in my dvd player but sometimes when playing the vcds there is a problem with the sound. The problem is that sometimes the sound doesnt go in time with what is happening on the screen. Sometimes when the voice of a person comes on, the lips of the person meant to be speaking doesnt move. The delay is only about 2-4 seconds. I was wondering if there is a setting mistake that i am doing. If anyone can help plz let me know...
thnx

Hey,
Have you checked the FPS on the avi? Is it 23.976 FPS?
What I would try first of all is to rip the audio out with V-DUB, the convert the movie in TMP using the audio that you ripped. On the left side under How To is a good description of how to do it. This has worked for a few movies for me.
If this doesn't work, send me of an e-mail and I'll tell you step 2 (not complete). I fixed the problem, but are having problems with quality of the movie. I'm away for the whole weekend, so I can't get back to you until next week.
As soon as I fixed the problem with picture quality, I'll publish a How To on this site. Almost there.... -
I'vebeen fighting this problem for months and ripping the sound out and readding it doesn't work. If you watch closely the picture speeds up and slows down then the sound catches up. I noticed it when the scene changes or there's a lot of movement. DO you have a APEX dvd player? I don't know if its my apex or TPMG. I've tried usuing different templetes and nothing works. Do a search on 'out of sync' or' lipsync' and you'll find a lot of reading material. If someone knows the solution to this problem please let us know what it is.

I convert a lot of movies to VCDs.. and have noticed a growing number of avi files/DivX movies with audio synch problems.. for some I have to rip the sound in VirtualDub and actually stretch the sound file with as much as half a minute using CoolEdit 2000 before merging video amd sound in TMPEnc. Time consuming to say the least.. I wonder.. what did the DVD ripper do wrong in the first place.. another strange thing is that some times the error isn't there when playing the original file in MS Mplayer.. but it sure is there when playing it in VirtualDub. I wish there were a good audio correcting program out there somewhere.

The reason I asked what the FPS were was because 1 movie I downloaded got out of sync when I converted it. I found out that the movie was running at 24.032 FPS. What I did was rip the audio with V-DUB, then convert the movie to 23.976 FPS.
After that I converted the movie in TMPGenc using the audio that I ripped from the original AVI. Only problem was that the quality got bad, the movie got blocky and looked like a VHS rip, but the audio was perfect throughout the whole movie.

Try using the audio gap correction in Source Range in TMpgenc. I had to set mine at -700 for memento

I think its just the stand alone players that barely are able to handle decodeing mpeg1. My computer plays the orginals and the VCD's fine but when played in my APEX 500-W there are always out of sync problems, i've goteen to the point that i just accept it as a problem with the cheap a$$ decoder ship in my player
just my 2p -
Fraunhofer-IIS's MPEG Audio Layer 3 codec
A VERY popular ripers codec
The Fraunhofer-IIS codec is very lazy and incorrectly sets the bitrate of the stream. For instance, a 48Kbit stream encoded by the Fraunhofer-IIS codec has a specified rate of 6000 bytes/sec, when in reality the stream is about 5971 bytes/sec. This 0.0048% difference may not seem like much, except that it causes the audio to race past the video approximately one second for every 200 seconds of video. One way to ‘fix’ this problem is to correspondingly adjust the video frame rate to compensate.
