XviD to VCD conversion results in audio sync problem

[DRP]

I've D/L'd an XviD encoded video. It plays perfectly using WMP 6.4 that come with W2K Pro. I have followed this guide: https://www.videohelp.com/tmpgenc.htm for conversion of Xvid to VCD to the letter using the very latest versions of TMPGEnc, VirtualDub & VCDEasy.

Following those steps revealed nothing amiss. I got no unusual error messages that weren't expected or advised about in the guide I was following. The problem is that when watching the video, the sound starts out synced to the picture but then gradually gets left more and more behind by the video.

It's not a huge amount by any means - maybe only a second or so (up until the point where it was annoying me so much that I stopped watching) - but it is annoying enough that it looks dubbed on the screen and I don't want to watch it.

Can anyone help out with this? Is this normal and accepted for XviD videos? I've never had anything to do with XviD before - this is my first attempt at converting one.

For the record, this is what AVIcodec has to say about the original XviD video I D/L'd.

File : 349 Mb (349 Mb), duration 0:44:17, type AVI, 1 audio stream(s), quality 58 %
Video : 307 Mb, 970 Kbps, 23.976 fps, res. 512*384 (4:3), XVID = XVID Mpeg-4, Supported
Audio : 41 Mb, 131 Kbps, 48000 Hz, 2 chan., 0x55 = MPEG Layer-3, Supported

This is probably caused by a VBR mp3 audio track (not XviD related). Extract the audio first, simplest way is to just open the AVI in Goldwave and save as wav. Use this wav as your audio source and the AVI as video source.

Did you already extract the audio as a WAV (as per the guide you linked to)?

If so, you might experiment and try just feeding the XVID directly into TMPGEnc (i've experienced many problems after extracting WAV from XVID whereas audio extraction is OK with DIVX).

wee haggis,


ditto. i don't extract audio anymore. i just scan for bad frames in vdubmp3 and delete them if necessary. then i load the avi into tmpgenc for both the audio and video. no problems, even with ac3 audio, since i installed odio dekoda. no sync problems at all!

Okay, I'll try this. I now have the latest version of GoldWave v5.04 but when I try to install it I get the message that it needs DirectX v8 or later to proceed. I only have DirectX 7 installed as I have only recently rebuilt the computer with a brand new W2K installation.

I duly went to the DirectX site and saw the latest version is 9a, but I also read that once installed it cannot be uninstalled. Everything is running just fine on this computer right now as it is and I'm very nervous about installing something which has the potential to break everything which I only reinstalled two weeks ago with no option to uninstall if it all goes bad.

Can you make any recommendations as to the worth of DirectX 9 on a brand new W2K Pro installation? Should I just go ahead and install it or would I be better off trying to find a copy of DirectX 8 and install that instead just to get GoldWave to install?

Thank you for your help.

Yes I did. I'm fairly new to this conversion caper having only recently bought my first DVD player so I followed the guide exactly - strictly by the book.

If so, you might experiment and try just feeding the XVID directly into TMPGEnc (i've experienced many problems after extracting WAV from XVID whereas audio extraction is OK with DIVX).

Okay thanks. I'll try this before the GoldWave thingy because if this works then I won't have to muck around with my DirectX installation and therefore risk breaking the whole computer again.

Okay I've done this and the result was an MPEG file about 3 times larger than it should have been (1.2GB) with *no* sound in it at all when played!

So what on earth went wrong there? I followed the guide exactly as before only this time I didn't extract the audio into a WAV with VirtualDub, rather I just let TMPGEnc have the XviD file I downloaded as the input for both video and audio.

Any ideas?
